Screen : NO SIGNAL

Hi there
I have also the famous "no signal" disease.
Conf : brand new (2 days old)
Athlon 2000+
256Mo PC2100
DD 40Go
MSI KT3 Ultra 2
MSI NVidia GF4 440 64Mo
Screen IIyama LM704UT
My question:
I'm surprised, as so many people claim the same pb, that MSI doesn't have THE answer!! (I see answers for Power Suppluand refreshrate)
It has to be an Hardware BUG!
I WANT a statement.
regards and goog luck from France

Mac Mini DVI to HDMI (blank screen, "no signal")

I have an older Mac Mini with just DVI. I bought a Monster Cable DVI to HDMI adapter (http://www.monstercable.com/productdisplay.asp?pin=4596) trying to hook up to a Samsung 46" LCD TV. All i see is a black screen with "No Signal". What am I doing wrong? This worked when I had a straight DVI to HDMI cable (from MonoPrice).

Just to update this:
Got my DVI to HDMI cable today!
Plugged it in, booted her up and was presented with a perfect 1080p HDMI signal without having to alter any display settings.
Fantastic!
In my display menu I have 10 resolutions to play with with , 3 of which are full 1080p, one is specifically for PAL tv in the UK.
Couldn't be happier!
Hope this thread helps anybody who is having any connecting woes between their mac mini and their sharp TV
Thanks

Apple TV shows nothing on screen- no signal

I have connected Apple TV to TV with hdmi cal le but the screen is blank showing a no signal message. Anyone had this before?

Welcome to the Apple community James.
You may wish to try the following:
Press and hold the menu and the up button simultaneously on the remote for six seconds, the Apple TV should then begin to cycle through the various resolutions available to it at 20 second intervals.. If you see a picture appear up on your screen, use the remote to scroll down to the OK option and select it.
If you can test it on another TV too, that would be useful.

Screen protector signal issues for iPhone 4?

I've been having the same problem with my iPhone 4 for a while now. The phone is perfect otherwise but on most occasions while using the phone i've been experienceing a loud crackling noise when making noise when making/recieving calls or no sound at all (no ringing and can't hear the other person speaking) however the speakers/mic work fine..
I've had a matte screen protector on the front of my iPhone ever since i've started using it and just recentley removed it and the phone is working perfect with the crackling/no sound problem gone! I have perfect clairity when making calls!
I was just wondwering is this possible that the screen protector could have caused this? To me I believe it has as the issue is now gone but my family don't think this is the case as it doesn't sound very likely a piece of plastic could do this?
Also if anyone could suggest a screen protector that could help prevent this from happening again I'd be very greatful. I think I might have to trial and error but some suggestions on where to start would be appreciated! My previous protector that I believe caused me this problem was the Power support HD anti-glare film ser for iPhone 4
Thanks in advance!

It's hard to believe a screen protector can cause such a problem, I still think it's tricky to blame the problem on your screen protector.
Maybe you could try some super thin screen protector and see if the same problem would happen again. If it does, then it's definitely something wrong with your iphone.

GTX670 - Signal lost/black screen after windows loading icon

Hello,
I hope I am posting this in the correct forum area. If not I do apologize.
Here are my specs:
Board: MSI Z97-G45 Gaming
Bios: ?? whatever pre-installed on mobo
VGA: MSI GTX670 OC
PSU: Corsair HX750 750W
Intel Core i7-4790K
MEM: 12 GB Kingston HyperX DDR3 1600 2x 4GB, 2x 2GB sticks
HDD: SSD Kingston 120 GB (Win7), HDD 1 TB WD 7200 RPM (Win7), HDD 1.5 TB WD 7200 RPM (storage)
COOLER: Corsair Hydro Series H60 Water Cooler
OC: no overclocking done by me..default settings
OS: Windows 7 64bit Professional
So to keep this as direct and as short as humanly possible here is my situation.
Had a gtx670 card that I had to send back to MSI under RMA. They sent me what looks like a new gtx670 card (no dust) that I received yesterday (4 Aug). Last night I removed temporary old card (9800gt) and plugged in new 670gtx. Things seemed to be ok, reinstalled driver after card was recognized. Played one round of Battlefield 4 for testing purposes and all seemed good.
Upon exiting the game things went south in a hurry. Moving the mouse cursor around was extremely slow and choppy. Mouse clicks were not recognized. I could not bring up ctrl-alt-del to get to task manager. At this point the cursor turned to spinning circle as if things were happening. However, after 5+ minutes of nothing changing I did a hard boot.
Restarted and after the windows loading screen the signal appeared to be lost to the monitor and I was left with black screen. This was with the SSD. I then attempted to load into the HDD windows OS that I hadn't logged into yet with this card and was greeted with the same issue.
I can load into Safe Mode with no issues. In safe mode I removed all nvidia drivers and was then able to load into windows normally using basic windows vga drivers. The moment I load the Nvidia drivers and restart the computer I then have the issue again. This happens with both drives.
I have reset the video card in the PCI-Ex16 slot and still received the problem. I have tried a different PCI-Ex16 slot and still had the issue. I put the old 9800gt card back in and windows loaded perfectly and without issues on both drives. I put the 670gt in and try to load into normal windows and I lose signal and get black screen after the windows loading screen.
I'm at a loss at the moment. I think it's the drivers, but could it be the card?
Doing some research I've come across some people saying there may be issues with the nvidia HD audio drivers that are installed with the video drivers. Could it be as simple as uninstalling or unchecking that particular driver?

Flashed the BIOS last night to the latest version and attempted to launch windows with the GTX670 card. I still experienced the same issue where as soon as windows finishes it's loading animation (with Nvidia drivers) and it goes to the login screen, the monitors cut out.
At this point I feel like it has to be the card. The moment I install the video drivers and restart, I have the problem of losing the signal/black screen.
What I have done:
1) Completely wiped any/all video related drivers from the computer and started from scratch. No success.
2) Ran Memtestx86 to see if it's a problem with my memory sticks. No problems found.
3) Put the card in a different PCI-Ex16 slot to see if there was a problem with the slot. No success.
4) Flash updated the BIOS on the motherboard to the latest version. No success.
I have a dual boot computer with Windows 7 64-bit installed on an SSD and a HDD. The problem happens on both drives. Yet, the moment I install my old 9800GT the problem disappears and I can login to Windows just fine.
I will be sending the card back today on another RMA.

Xorg hang with "No Signal" on screen after incomplete -Syu

Hello everyone.
I had a uptime of ~60 days and decided it was the time to pop -Syu and take a deep breath, this time, it choked me ..
pacman -Syu was downloading almost a Gig of packages and was near the end or just started installing when the screen just got cleared suddently and showed me this ..
1888218888++++++++
Yes, nonsense, something went terribly wrong, and I did not use it meanwhile updating, it was just updating all by itself when this happened..
Afterwards I did another pacman -Syu after a reboot and it installed the last packages but startx gave me a screen without signal (No black screen or anything, just like if it was unplugged) .. The rest of the system is freezed and I cannot reach TTYs by CTRL+ALT+F-keys absolutely no response, not even by network services like SSH.
I now am in doubt, should I do a reinstall of all packages on my system to be sure this is not caused by incomplete installations/upgrades of xorg and it's parts or should I try anything else?
xinit/startx is reacting the same ..
I have not been able to find a similar problem by searching, all refer to the Xorg hotplugging which is disabled in my Xorg which bugged me on the last -Syu ..

UPDATE:
The official NVIDIA driver caused the problem since the "nv" opensource nvidia driver works fine.

What is going on with my iPhone 5s touch screen?!

I bought my iPhone 5s in November of 2013. I've loved it so far, until about a month ago when I noticed a major problem. When I type on the keyboard vertically (haven't tried horizontal) different parts of my screen start being activated. For example, the amount of times I've been texting someone and end up sending a FaceTime request (so activating the top right corner) is ridiculous. I even tried posing this question originally off of my phone (why I thought that was smart, I'll never know), and I found myself typing in the question tab or refreshing the page or typing in the middle of random words every single time. I notice it very badly in iMessage, but I've also seen it happen on Facebook as well. There are times when I even find myself three pages back from where I was at first, because of typing/touching. Basically, I have no idea what's going on. Some days seem better than others, and other times I can barely send out a message to someone. It certainly helps when I slow down the pace of typing (I thought maybe hitting 'blank' parts in between keys was causing it), but alas this only helps mildly, and sometimes not at all. I also don't believe I see this touching error outside of typing (however, this could be because I don't notice it as overtly). It seems like if I was capable of recalibrating the touch screen, that would help. But the iPhone doesn't come with a recalibrating option other than wiping the phone. I'm just at a loss as to how typing the bottom half of my screen sends signals to the top half. Am I the only one facing this? Or does anyone have any remote clue as to what could be going on/can be done to stop this? Obviously, it's very inconvenient in my life.

[P6N SLI Platinum] black screen NO BOOT after D-bracket replug [RMA-SOLVED]

Quick setup specs;
P6N SLI Platinum
E6600 (box/stock 2400mhz basic)
2x 1Gb DDR2 6400 Gskill HZ
Sapphire ATI X1600Pro (PCI-e basic)
Aerocool Zero DBA 620W
(2 HDs sata, 2 Hds pata, 2 optical pata at first -all OK at first, disconnected after, so irrelevant here ,( )
(XP Pro clean new install from start)
I tried to check the forum old posts before trying to write that new one, but could not find any really related totally adequate posts so far (or i missed them, sorry if so, then -?). I could already find very useful informations on first aid usual 'rebooting' procedures to follow with minimum new boot configurations, d-bracket new LED signals etc. But so far no luck, all same, nothing better, nothing cured here for the stuation here. ,(( Also excuse my english if not perfect, i am not english either. ,(
VERY bad & sad problem here... ,(((( :
All was working perfectly great during 5 days.. the P6N SLI platinum install went GREAT initially (as normal, not a first pc built, all normally happening, so far so good, etc).... all hardwares compatible together at first (dedicated ATX 'full' 8x8 pins connector too for the cpu only for ex -all working perfect at first try. quick tensions 5V/12V under msi dual core control tool perfect too etc), was great easy going/ great strong ultra-stability feeling on the hardware side.. i was just now concentrating on the software side (no special BIOS tweaks even attempted so far, all on basics-normal e6600/ddr2 auto-settings, apart at the end ddr2 quick test -when problem occured- on 450(900?)Mhz at 2.1V, far far easy under its possible specs max anyway.. and had been working perfect for 3 days with that little ddr2 boost try -no time for special bios further tweakings now, etc), reinstalling and transfering/reorganizing slowly my necessary files/hds/softwares from old to new setup, no oc, nothing special tempted (i was planning oc, new cpu more suited fan/silver6 etc only for the end..), LAN file sharing setup done, Realtek audio setup test done, etc ; installation had been so far one of the quickest and problem free ever... explaining maybe also my fatal lack of cautioun for just (too much) 3 sec in the end after 5/- days of perfect working new ring going on.. ,((( :
At first, i also tried to immediately install the D-Bracket too to check possible hardware install problems -very useful feature i of course thought too..and wanted to try too, "in case of"..- (installing it from quick reading of the printed manual..with no colour pic coding inside..and quick error coming from there thereafter with an initial mismatch usb/jbd1 inverted plugs connections.. *both* having the exact same pins numbers and dispositions, beeing side by side on mainboard layout.. and so able to connect both headers indifferently.. so i did not see it immediately (( .. and no way to see it otherwise as such, anyway.. ,( ), just to be sure all was ok. I noticed that LED were of course, never lightning (not normal).. but as EVERYTHING else was working fine (GLAN, sound, etc etc).. i did not bother more than that -- error checking not necessary.
Till that fatal clumsy day i wanted suddenly to.. check the D-bracket too. ((((
All was working well, XP pro opened for hours as usual etc..
i had not yet totally finished to install the motherboard in the pc-case (always on desk, free in sight..)... so i could always see the connections on it. ... and i noticed that ... the colour headers codes were NOT matching (usb=yellow..).. i had just stupidly initially badly connected the D-Bracket jdb1/usb adjacent plugs (inverting them), so... And still, all had ever worked perfect.. except the D-Bracket, of course, was sending back no lights then, obviously.. so i did the fatal error.. confident all was stable enough and strong if even that initial plug error had had no consequences at all.. i did the fatal bad move to try to UNPLUG the D-Bracket connectors and put them back in right orders WITHOUT switching OFF the power supply so... like an hot USB plug, sort of, in a way. fatal error.. :( :( :(
As soon as i began to remove the usb/jdb1 connectors and put them back in normal order... the system suddenly SHUT DOWN ... no special bad noise, no special smell.. just sudden SHUT DOWN.
From there.. impossible ever to boot back again the so far perfectly working machine (((((((((((( , always same till now :
i switch on the power supply.. orange led appears on motherboard (ok)... i switch on the motherboard.. green led on motherboard appears (ok)... CPU fan begins (ok), video fan begins (ok) .... and... NOTHING.. total black video screen. no more even possibility to see the BIOS. :( total dead startup .. and the fans are going on eternally, blocked eternally in that inital startup with leds on too (no sudden shut down after a few seconds.. just.. nothing)... :(
Suprem irony.. the D-bracket LED seems to 'work' now.. "of course". Just the PC no more booting at all ^. Only thing is that only green LEDs are appearing, no red ones... simply the sequence, from start and never changing :
1. GREEN 2. GREEN
3. GREEN 4. (---) (not red, just nothing -?)
If i look in manual, it means "Testing RTC (real time clock)". I don't know exactly what it means *here*, but sounds to me it is the most basic initial first BIOS checking.. and BIOS can't be reached for even that so ; BIOS fried???? :( :(
I tried every 'standard' things recommanded usually here in older posts, for new boots recovery attempts thereafter in such 'boot errors' situations (clear cmos button pushed in every possible ways -quick, long, quick etc..-, removing little by little everything but the very minimal least energy taxing setup; keyboard, cpu, video, motherboard; 1 ddr2 nearest cpu slot.. point).. NOTHING. Worst, i tried to boot with one of those elements missing.. exact same D-Bracket lightning from start to.. eternally (123 GREEN 4-nothing). Even tried to remove the little (cmos?) KTS lithium battery for a few hours -that could work sometimes with the old already ultra-sensitive amd/nforce2 chipset bioses problems, so i tried there too-?-; same 3 green lights and fans running and nothing else happening from there.. ((
Always the same; total dead boot as above. black screen. no possible access to even bios panel. ,(((
So my desperate questions, now: of course, the origin is obvious here; all happened "by my fault" when i tried 'too quickly' to 'hot-plugging' replace correctly the D-BRACKET plugs *without* switching off the power supply... all shut down suddenly when i put back correctly the usb& jdb1 headers... :( ;
- do you think there could be any possible last HOPES to recover the situation that i had missed (a well known situation in such d-bracket handling 'common' (?) connection error, a simple trick to try i had missed ??)
- do you think i FRIED something in the process on the motherboard ?? :( :(
- do you think it is 'only' the BIOS (fried????) ?? :( :(
- do you think i could have fried a specifical external key component in the process (not necessarily motherboard) : ddr2 modules, cpu, video card????? :( :(
- is my only solution is to send the motherboard to RMA (no other ways now) ???
please, don't hesitate to give me any possible hints to try to avoid the RMA process.
can i avoid it, right now?
is that possible to fry an whole board just with such a D-Bracket 'hot plug switch' (on a so far perfectly working -light- setup - no oc, little video card, etc) ???? :( :(
That is the only C2D Intel/ddr2 motherboard i have here around. No possibility to test elements by elements for precise error checking (cpu, ddr2 modules, video card or powersupply).
Only things i could check so far are;
- the power supply (aerocool 620W zeroDBA) ;
i tested it back on my old amd xp-m nforce2 setup.. always working apparently. NOT 'fried' so, apparently. but no way of course to test for exemple the special 8x8 (or 8x4) Intel ATX cpu connector on old xp-m motherboard. But power supply NOt fried at least, apparently -?
- the video card.
no way for me to really test the pci-e card on other motherboard around but.. i tried a very old PCI VGA card.. that one works on old setup.. and on P6N, no effect, doesn't improve the situation. So, not sure the new pci-e video card isn't fried.. but a new video card doesn't correct the dead boot problem.. (
No way for me to test the ddr2 or CPU directly though.
Do you think DDR2 or CPU could have been fried in the process too ???
or just, as i fear anyway, 'simply', the motherboard BIOS fried -??? :-(
Really, thx for any suggestions..
if there could be an 'hidden' trick i did not try yet to try to recover the (initially working perfectly!!! (( ) setup, WITHOUT engaging the motherboard RMA process (at least 2 or 3 weeks lost here to wait the return..online store etc..)....
please, suggest me.. ,((
i am *really* very sad of that stupid clumsy idea to want to 'enable' the D-Bracket.. all was working great so far.. and i lost all with just that stupid idea to try an hot plug bracket reconnection without switching off the power supply it seems.. can it be possible,sigh?? all seemed so stable before that, that i.. just lost my usual cautious just 3 sec too long it seems... :-(
Thanks in advance
hoping post not too long too, but i tried to expose the situation as precisely as possible; first time i ever had such a problem with a motherboard/system install.. that is quiet ironical knowing it was also the best and quickest/easiest easy going new built i ever had so far too.. till then ,( .. and all came from the 'helper' d-bracket 'luxury second hand possible boot helper diagnostic tool' checking in the end too, here.. really hoping i can avoid an RMA process.. and no other hardware elements (apart the motherboard?) could have been damaged in the process ? ,(((

hi, thx a lot for the quick answer. sorry for the length indeed (i did not know exactly how to describe the situation.. without omitting any later possibly important details).
Alas, i already tried that many times in following interesting asnwers on similar problems in old posts here; did NOTHING. ,(
But after your post, i tried it again, and removed for the remaining *hours* (6/8h?) the cmos battery as suggested again *too* so -pushed again the clear cmos button etc when battery out, then when in again, then replugging the powersupply etc; NOTHING better alas too. always same, no boot, black screen, no bios. ,(
Problem always the same, to sum up, for clarity:
power supply on => orange motherboard led is lightning up, motherboard on => green motherboard led is lightning up, cpu/video/case fans are working up as normal and.. that's all. nothing else forever. black screen. no signal. not a single chance to get again the bios setup screen.
another detail i omitted, maybe; keyboard lights are all lightnng up too.. and stay blocked in that state too. tested with 2 different keyboards, same. to shut down the leds, fans etc, only one solution, shut down the power supply button directly, at that stage.
right now, i test on barebone minimal system as recommanded too;
cpu, 1 dimm (closest cpu slot), video, keyboard. all rest disconnected.
i of course tried to reset the cmos with the 'magical red button' many times before, with power supply cable plugged out, pushed the button trying almost every possible way so far (quick, long, long sequences, short sequences etc etc)... changed NOTHING so far -is that thing working?? ,(. and right now, same after hours with cmos battery removed too. ,(
the d-bracket leds are always (now it is correctly plugged..) :
123 GREEN 4 (nothing)
"Testing RTC (real time clock)"
another 'interesting' detail is that; those leds are appearing IMMEDIATELY after the motherboard is switched on, from start (green led appearing on P6N). and it is staying as such till the end. nothing else. i tried to connect also the case speaker ; no bips, no sound signals at all too.
I also remind the system was WORKING like a dream during 5 days *before* i had that sudden TOTAL boot problem.... AND i touched almost nothing in the bios too all along, for initial security reasons too.. (i was concentrating on the software installs anyway right now, NOT on the oc side..). The ddr2 quick little change i did was also the ONLY change i tempted to simply test quickly some setting i already saw working without problem with that P6N and that kind of ram.. and it was working without problem so far too, so.. all the time idem. And it had been perfectly working for 3 days as such untouched from there; no problems at all (those memory modules have been seen on that motherboard largely at those specs, why i did that quick test anyway.. far under their possible max -micron chips). it was even working so well i forgot to put the setting back as default after that quick ram test.. so much it was stable too (even if i had not time to do real memtest test on that one - i did for many hours with the initial automatical default settings too, to check the ram quality, was perfect for many hours, so ok too, no bad ram initially too-; was so stable for all my XP software installs operations etc.. that i forgot it thereafter, to be true..why it stayed like that till that moment (incidently).. but i preferred to mention it 'just in case' though, yes. i also did not push at all the dimm voltages in the process, it was always far inside the specs at 2.05V to be exact -usual for that ram too up to those numbers easy for it. i did not push the ram voltages either so..).
The problem ONLY appears when i wanted to unplug the *initially* badly connected D-bracket headers so (inverted headers.. but that caused NO problems either so far too for the system stability.. only the LEDs were of course not working so far..) : i did the error to NOT switch off the power supply. :(
*then* immediately the system shut down... and above situation appeared. ,(
BUT all was working perfect before.. ram setting included so. ,((
So my simple questions now too ;
- do you know what means *exactly* the d-bracket message 'Testing RTC" (123 GREEN, 4 nothing).. initial bios problem, isn't it?? other ways to recover it now?? ,((
- is it a WELL KNOWN PROBLEM when we try to disconnect and replug too hastily the d-bracket headers without switching off the power supply (*my* main erorr here, it seems :( :( ) ????
... and of course, do you think it could have *fried* another key component (cpu, ram -?? why i reminded the setting, just in case-?-, video card? .. ) with that d-bracket initial disconnection error ... ,(
as i said, i have no secondary c2d/ddr2 motherboard here : no way to test the cpu and ddr2 modules on another motherboard to be sure too here. :( i absolutely can't know if they have been damaged or not, here.. :( :(
any other idea for the motherboard itself though ??? ,(
once again, thx a lot for any suggestions and precisions on that problem (is that a COMMON well known problem with the d-bracket, when we unplug and replug it without extrem care like i did -my main inattention error it seems.. mainly because all was so stable before too.. ((( - without shutting down the power supply/system FIRST ???? can it be possible 'only' that shut down all the system??? (( )
thx in advance again +

Monitor says - "No Signal"

My G3 has been connected to a 21" Dell (really a Sony Trinitron CRT flat-screen) for over 6-1/2 years, and worked flawlessly. One day, on start-up, I get a blank screen with a terse message… "NO SIGNAL." (!!) Checked all the connectors, pulled & reseated the video card (an ATI Rage 128 of 16MB, rev. 1- #661-2190, with the extra MPEG-2, DVD decoder- #661-2109); after two days of non-sense, took it to the shop… where it worked flawlessly on THEIR service counter! The battery needed to be changed, and was. Took it home, and it was "s-o-s." "NO SIGNAL."
Out of desperation, I connected a spare 20" Apple Multi-scan CRT (also a Sony Trinitron), and everything worked… 1-2-3 and we were on the desktop. Over the next two weeks, the Apple Multi-scan never failed to work.
Thinking that I had a +monitor issue,+ I acquired a Sony 20" TFT flat-screen. Connecting it up, I got the same results… a blank screen with the terse message… "NO SIGNAL !!" Unsavory language followed. Sooooo, I acquired another video card. Inserted it and connected up the flat screen. Again… NO SIGNAL !! The G3 was on the counter four times and worked like there never had been a problem. Even when I took the G3 in with the Sony TFT flat-screen. They said to hold down the Command-Option-P & R keys on start-up. This will bring the flat-screen up, but on start-up later, itz back to business as usual. IF my video card were the problem, the flat-screen would NOT work at all; once up & running, I've made changes to all the monitor settings- to my satisfaction. I've run it for three hours. Re-setting the P-RAM has not changed the blank screen & NO SIGNAL problem.
So, for now, itz the G3, Multi-scan and me. The flat-screen sits. Appearantly, there seems to be BOTH a hardware and software problem. But I'm leaning more towards the software. However, my brainbox DOES know what monitor is connected to it, viz the DISPLAYS pane.
WHAT say you– Grand Wizards?

Hi! and THX for your reply . The Sony TFT LED flat-screen has 2 RGB analog inputs (J15 & J16) and 1 DVI-D (J17); the flat-screen knows which input is connected to the G3. In the downloaded Sony TFT LED Computer Display manual, on page 15 - under the "INPUT SENSING ON/OFF menu," the monitor automatically detects an input signal to an input terminal and changes the input automatically. While there are no specific "switches," there is the menu. Apparently, I can turn off the *automatic sensing* and manually set the input. I haven't "tried"that just yet. When I rise to the chore of moving things all around again, I'll try manually setting the input. However, I doubt that this will have any effect on things.
Not to throw more dust into the air and further confuse matters, I am begining to suspect my original OS X 10.3 install disk; the one I acquired was for/from a 12" PowerBook G4… @ the time, brilliant me said… "So itz for a 12" PowerBook, so what? Itz Panther, right??" After the original install, there followed 2 updates,the last one being 10.3.9; up until recently, there have been absolutely no glitches on start-up. ALWAYS full-screen… until about a week ago. NOW, the last half dozen start-ups, have been with the reduced screen (the gray "bite-of-the-Apple) for the 12" PowerBook (!!). In any event, I am acquiring a "regular" version of the Panther install disk.
I find it strange that what triggered this whole mess (apparently) was failure of the PRAM battery. Or perhaps, that was just coincidental? REGARDS.

Iphone 5 signal dropping issue

Hi guys,
I just got my Iphone5 as a gift from my friend month ago.
It was really exciting when I first got it. However I found sometimes when I unlock the screen, the signal will suddenly drop to 1 bar and then searching, this will take seconds and then appears no service. If lucky, the signal will come back soon. But it still really annoying! And this happens more often recently.
I tried reset network setting few times but it didn't help at all. So I thought maybe is due to carrier's issue. I am with Vodafone, so I bought a Telstra prepaid sim and try to see if this fixed the problem. But still, keep lossing signals!
This is so frustrating!
And my battery is draining really fast as well, even I turned off wifi, bluetooth; minimum brightness; all background apps off. its still draining!!
Anybody got the same issue here? I tried google this but seems nobody got the similar problem
Could anyone help me please?!
Thanks!

Thank you for your answer!
Did your phone just fixed itself?! How long did it takes?
I'm worried if it's actually no signal after we lock the screen? I mean once I left my phone in the bathroom and I forgot so I called up but it just directly into voicemail! I thought I lost my phone!!
And what if I need to make a emergency call??

R9 280x TF GAMING: Sporadic black screen on boot and system resume

Link to my full system specs
ASRock Z97M OC Formula (running latest BIOS version)
Acer B296CL Monitor over DisplayPort
MSI R9 280x 3GB TF GAMING, vBIOS 015.042.000.000.003435, S/N 602-V277-250B1406048461
AMD Catalyst Omega Driver: 14.501.1003.0 WHQL (latest non-beta driver)
When booting my computer in UEFI mode, occasionally, my monitor does not wake from sleep and the screen remains black until Windows takes over and the login screen displays. This seems to usually occur after the computer has been powered off for more than 10 minutes. Sometimes this never happens, the screen remains black the whole time, and I need to hard reset. Sometimes it boots fine.
This black screen / no signal issue also occurs far more frequently when attempting to resume from sleep. I strike a key on the keyboard or hit the power button while the computer is in sleep mode, the computer wakes up, but the monitor never turns on. This forces me to either hard shutdown or reset in order to restore graphics.
In addition, I have a Razer keyboard that shuts off its backlight when the display is turned off, and it remains off when this problem occurs. This likely means that there is a problem with the card, drivers, or something else, rather than cabling. I might just RMA if we don't get anywhere here.
Perhaps a good first step would be ensuring that my card is flashed with the latest vBIOS. Can you send a link to that?
I'm also wondering if ULPS might be interfering, even though I am not in a CrossFireX setup.
Other than this MAJOR issue, the card works fine when playing 3D games. Though, I had major issues with video artifacts when playing 2D games or doing anything else simple (web browsing, moving windows) because of the absolutely terrible decision to underclock the past couple generations of AMD cards so much that the GPU can't function. I solved this by modifying an OverDrive profile to raise the idle clock to 850 MHz, but not overclocking at all.
Thank you.
Meta discussion for the mods (feel free to PM me if you would like to discuss this further, in order to keep the discussion here on topic): sorry for not immediately opening up another forum topic when commenting on this issue. Every single other community that I've been a part of prefers to keep users with the same problem on the same thread. In my experience, mods yell at people for opening up duplicate bug reports and duplicate issues far more than they ask people to fragment information across multiple threads, therefore making it difficult to consolidate information.

It could be a mobo issue, but all of the quirks seem to point to the card.
I do not recall if I tested the card in another PC, but I no longer have a second desktop to test with.
I do think I tested an NVIDIA card on a separate Windows install with this build though. No issues there if my memory serves correctly. I've been troubleshooting this issue for months, and I'm becoming tired of this stubborn problem, so the attempts at problem-solving are becoming blurred.
vBIOS is attached.

Problem with X -config (freeze + black screen)

Hi, everyone. I'm a newbie in linux, so dont punch me .
I was following the beginners guide & after X -config /root/xorg.conf.new got freeze + blackscreen (alt + ctrl + bckspc or alt + Fn dont works).
I have created /X11/xorg.conf & can start X server, but X -config /root/xorg.conf.new or /etc/X11/xorg.conf gives black screen (with signal).
My VGA is HD3850.
Any ideas how i can fix it?

My english is fine (i read well at least) .
At first message i said
I have created /X11/xorg.conf & can start X server...
I =can= start x server --- its mean that startx works fine & i can see 3 windows with clock . And if you mean that i dont want use x -config, then for what all this manipulations with reinstalling was?
Besides "Xorg -configure" & "x -config /etc/xorg.conf" are different things for me, because one create the basic config, while second test this config. So i thought you mean that i have to create it from scratch without using any commands
... Damn.. i just have read english & russian beginner guides. Russian says: "after installing xorg u have to create conf file, using Xorg -configure, then test it with command X -config /root/xorg.conf.new & IF IT WORK - copy to /etc/X11/xorg.conf. I didnt find that in english version .
Well, thank you for your patient & help . I think, that problem is solved (i think - say me if i wrong)
But i still want to know, why x -config /etc/xorg.conf give me that black screen + freeze, so if anybody knows - plz, message me.

Not a vid from me but its what it does.
Was his diagnostic of motherboard failing right?
Also I reseted pram and smu with no changes at all.
I cant connect another monitor since i dont have one.
Apple is kind of a long way from my home so I want
to have an idea of whats happening.
Thanks for any help

Well i think the board finally fried today. I waked it up from sleep, got a screen for half a second, then a strange noise and a black screen.
Now even with an external monitor i get no image. The screen says signal, no signal, signal, no signal, etc. My friend has an Imac like mine that he doesnt use since he got a macbook pro and told me if i needed pieces, i just have to tell him. So if you got an idea of whats wrong, I'm open for suggestion.

Single screen KVM with dual screen setup

So here's the deal. I have dual 20" cinema displays hooked up to my Quad. I took one of the displays and hooked it up to my IOGear DVI KVM (http://www.iogear.com/main.php?loc=product&Item=GCS1764) so that that display could be shared with my Powerbook G4 and my Core Duo MacMini. However, when I change ports on the KVM, the secondary display "disappears" from the PowerMac and it starts freaking out. Sometimes it will just try to detect the screen (constant signal flickering) for a minute and then give up and operate as a single screen system but most of the time it tries to detect the screen for 2+ minutes until it just crashes the whole computer and then I have to reboot the PowerMac.
Any ideas?

Removing pin 16 on the DVI cable to the PoweMac might help. See the last item in: <http://www.gefen.com/kvm/support/faq/>
