Black screen - Leopard problem?

I woke up this morning to discover that the backlight on my iMac G4 (USB 2.0) running Leopard wouldn't come on. I figured it was just a random hardware failure, probably of the inverter board, but then a friend with the same model iMac called me to say her system did the exact same thing today as well. It's probably just coincidence, but Leopard is known to have some graphics driver problems caused by the latest updates. I'm wondering if a lot of other iMac G4 owners have seen the same failure recently since upgrading to 10.5.2 and Leopard Graphics Update 1.0.

Does anything come on?
Have you ever changed the PRAM battery?
I would check it first. When mine went, I had no response from my Mac at all; just a light on my power button; absolutely no boot at all.
Check out things in Texas Mac Man's Battery, PRAM, PMU tutorial on the subject. His tutorial is a little dated (don't believe it even mentions G5's) but the info in it, except SMU not being included, still applies.Cheers! DALE

N770 TF 2GD5/OC Gaming black screen blinking problem

Hello there,
i upgraded my PC 4 days ago with a MSI N770 TF 2GD5/OC Gaming graphic card. I installed the newest graphic drivers. Clean install and without nVidia Experience. My problem is black screen blinking when i am playing or watching. Screen turns to black for 1-5 seconds like monitor lost its signal. It happening when i click to fullscreen button. No matter if its in youtube or windows. It happening every time. It does the same when i am playing. Big lag and then black screen blinking for 10 sec. Sometimes more sometimes less than 10 sec. I used Google and i am not the only one, who have this problem. Some people says, that GPU BIOS flash helped but in MSI website is only one BIOS and i dont know if its newer than mine or not. S/N of my card is 602-V282-380B1404100829 (if it helps) and my current bios is here h t t p ://leteckaposta.cz/186979270 (just click on the GK104.rom in the middle). I think i tried almost everything. Registry clean, anti malware and spyware, drivers re-install, turn W Aero Off, UAC off and other worthless tips how to fix this issue. I monitored my PC with many temperature software and i am 100% sure, that overheating isnt the problem. So could you please check if the MSI Bios is newer than mine or tell me what to do to fix this irritating problem?
Thank you very much
PS: I am not a native speaker and english is my 3rd language tbh, so please excuse any grammar mistakes

you are using latest vbios version, test the card in another PC

Black Screen render problem

When I try render it is a black screen then makes a sheep noise PLEASE HELP I'm using a macbook air

The sound you are hearing, is the sheep having too much grass.
This is a general render error. If you want more information on what is causing this crash, you should check your render error logs.
You can find where they are stored in the Render Settings --> Log menu.
That being said, it is usually three things that cause this. Two common, one uncommon.
The biggest culprit is a plugin which is rendering badly.
The second, is a codec which is not encoding properly.
The far third, is that your RAM is dumping.
If you want to post those, maybe we can take a look and talk you through it, but without knowing more about what's going on, we can't just tell you what is causing the problem.
Good Luck

Black Screen = Inverter problems and more

I have a 17" MBP and recently had my display go totally black on me on a plane (which i see has happened to a bunch of other people here)
Took it in and the repair guy won't send it to apple on my warranty because of an unrelated dent in the corner of the computer, which he says apple will claim accidental damage on.
The dent occurred 8 months ago, and my display broke down 2 days ago. All apple could offer me was to get a second opinion, and if the dent is far enough away from the inverter, MAYBE they'll repair it.
Any thoughts on how to proceed here? I'm getting pretty frustrated.
Thanks.

Oh, sorry, didn't get that. That monitor was actually called the 22" Cinema, not 21". Apple had a 21" CRT but I think that was called a Studio Display, so I got confused.
So sometimes it works correctly at 1600 x 1024 under Windows (Bootcamp) and sometimes it doesn't? Is that correct? Those times when it is giving a black screen, have you considered trying to establish a VNC connection to the mini from another computer on the network? You might find that the wrong resolution is being sent to the ACD those times when you get a black screen. Though that doesn't really tell you why it's happening, it's a starting point.

Toshiba with black screen, similiar problem?

Hello forum, hope to hear from someone for tech advice. I have a Toshiba model 32av52r flat screen TV. It worked fine, but we went away for awhile and when we came back it no longer works. I am ok and confident with working on things like this. The TV has a SOLID green light on the bottom front. No picture or menu signs. I live where there are occasional power outages so I believed this may have been a problem. I searched via web and some experts believe the power board may have failed. I order on via ebay and replaced. I still get only a green light on the bottom. I have hooked up to a satellite receiver (I use a video cord and the three cords ((red/white yellow)), but am not sure I have those hooked up right.....but I still would think I would get a 'no signal' display or something. I am hoping for some simple checks I can do....is there a reset button? check for power/ohms at certain points?
It seems that others have had this, and the solution is inserting USB in to side??? I assume one would would have to download something.....? Thanks

turn off the tv then unplug the power cable,disconnect all the devices that is connected after that press the power button for about 10 sec.
plug in the power cord then turn on tv.if still no display,try to press the menu button,if menu button is not showing it is a possible lcd screen failure or system board

Ipad black Screen display problem?

Having a problem today. My iPad fell off my desk (with its case on) and when I picked it up & tried to unlock it i was completely black. I connected it to itunes and did a reset but it's still black it actually talks now and any kind of display or the apple logo appears very briefly (like a second or less) but disappears ?

You could always try the general steps of restarting, resetting, and then trying to restore but Im thinking that this is most likely a hardware issue so you'd be better off visiting an Apple Store first to see what a Genius rep thinks it could be.

MSI GX623 black screen, Afterburner and that old story

Hello. So maybe someone will know the cure for my problem. I have an MSI GX623 gaming laptop, i have it for like 3 years, i dont remember. So when i bought it I started playing games with it (because it's a GAMING laptop :D). After some time I've started to have black screen/crash problems. So because I had warranty, I gave the laptop for repairs. As I remember, they've changed GPU and cooling system. I took it back from them, hoped that the problem was in the past, but that same day I played GTA 4 and there it is again. All this was like 2 years ago. Until this day I used MSI afterburner and it helped, but sometimes the problem used to show up again, so I used to leave pc on sleep mode and it helped. Right now, I'm using a cooling pad, the afterburner for some time, like half a year. It was like a month until yesterday it all started again. Everything was fine, i turned my laptop, open LoL to play, started the match and bammm, black screen. I thought, ok, not the first time, lets just restart the laptop, open afterburner and it will be ok. Not so fast, as much as I wanted it to be ok, all day I couldn't play anything, not nba 2k14 not lol (these are the 2 games I played for like half year). Well all day I had to watch Sopranos and Prison break, no lol or nba :/ I left it on sleep mode overnight and today it's good as new, played lol, nba, it's all cool, but after some time ( the laptop wasn't shuted down for no time), a short, like few hour brake without games, wanted to play lol and there it is again. I don't know what's wrong, the temperatures are fine, more like fine, yesterday i cleaned the inside of the laptop from dust. Everything is perfect, but it's still there. I've updated afterburner, but no help. Maybe there is some new solutions to this problem without afterburner? Thank you BTW, I use windows 7, but these days it's like xp, everyone uses them D: thx for the help )

Could be heat related. Do you know what temperature your CPU and GPU are running?
Just to be sure on the driver front, uninstall your current graphics card drivers, run >>Driver Sweeper<< to clear any driver traces, reboot and then install the ones from the MSI website: http://eu.msi.com/index.php?func=nbdriver&maincat_no=135&prod_no=1702

My mbp always hang (black screen but still keyboard light)(snow leopard and lion) and self hang and restart(mountain lion), How can I do? (I report problem to apple for 100 times but no reply)

I use mbp late 2010 (MacBook Pro (15-inch, Mid 2010) Serial Number: W802627ZAGZ)
(core i7 2.66GHz. 15" 4GB 1067 MHz DDR3) and change display to highres (1920x1080)

I use it and it still hang up (not it reach 100 times errors) how can I do with this problem?

I'm betting that it was originally Partitioned with Snow Leopard.

Have 2004 eMac...screen goes black without notice. Getting a reconditioned 2005 eMac. Can I have the HD swapped from old eMac to reconditioned one without problems??? Black screen is called "collapse to black" and occurs 4-5 daily

Have 2004 eMac...screen goes black without notice. Black screen is called "collapse to black" and occurs 4-5 daily. From what I understand, this is due to bad capicators????? Found a reconditioned 2005 eMac on line. Can I have the HD swapped from old eMac to reconditioned eMac without problems???...with regards to software applications. Old eMac is running 10.4.11 and reconditioned on runs 10.5. Suggestions, tips would be greatly appreciated. Thank you.

Might want to make sure both units are not affected. This is the range of serial number from the now-defunct Apple Repair Extention Program for USB 2.0 eMacs:
G8412xxxxxx- G8520xxxxxx
YM412xxxxxx - YM520xxxxxx
VM440xxxxxx - VM516xxxxxx
A "collapse" is more indicative of a video cabling issue, but the bad caps produced such a wide range of problems that it's hard to sort through them.
If the old eMac is a USB 2.0, which a 2004 unit should be, the HD should exchange with the new one. As the last of the eMacs shipped with Tiger, the new computer should have no probelms with a 10.4 boot volume on the old drive. You can upgrade to Leopard one you have hte new disk in place.
NOTE: Takeapart and reassembly on the USB 2.0 must be done "just so" or you can permanently damage the power switch. Instructions for the USB 1.1 takeapart are slightly different , and the power swtich damage is usually caused by people using the older instructions on a newer eMac.
If you are not up to the takepart nor can you find a local computer tech who knows these. consider taking the drive out of the dead computer(won't make much difference if you damage that one as it's dead), buy an external Firewire enclosure, and put the old drive on it and use it to move data to the new computer. Then you can leave the external attached as a backup drive.
Is the new one a 1.42Ghz model? They have been practically trouble-free around here. We have one and it's been rock solid since we bought it as a refurb in Jan 2006. The 1.42G has the advantage of a Core Image-enabled video chipset, the ATI 9600.
And all USB 2.0 eMacs can, with modern memory modules, support up to 2G of RAM.

Imac 20" intel Leopard black screen, does not start up

Imac 20" intel Leopard black screen, does not start up,
yestarday i put my imac aluminium in sleep, when i wake up this morning the computer did not start up from sleep and also did not start up from the power button back, i try several times and nothing, i hear the sound of the start up but i remain with a black screen. What can be the cause? The video , maybe? I did not install any hardware lately on it.
note: i have a wireless keyboard & mouse

Not running Leopard (Panther), but I have a similar problem on my 24" iMac. Computer was working fine last night (I shut it down) and when I went to boot up this morning the computer is stuck on a black screen.
The boot up sound is initiated but nothing after that. The power light stays at full brightness, if I touch the power button the light blinks and then after a while it goes out. A full reset does nothing. I've tried reseting my PRAM, which works because I hear the start up sound twice, but no change to the black screen.
I don't have access to another Mac, would inserting the Startup Disc I received with the computer do anything?

Installation on Macbook with black screen problems

Hi, Having a hard time installing BootCamp on a Macbook 2007 model..
It would go to the point when it is restarting from the XP disk to install and show a black screen.
I have tried everything I have read.
remove battery.
reset pram
do disk utilities off of Leopard Disk...
The machine is running 10.5.6
But the kicker is that it would install Vista fine from two different installation cd's but I have tried XP SP2 from at least four different cd's and would have the problem.
Anyone have any idea why it would install Vista (both home and business edition) fine but not XP SP2?
thanks
rsp

I'm dealing with this problem for a week now. Fact is, I could when I got my Mac do the partition using Boot Camp and install Vista. But last week I got an error message that windows can't find the ntoskrnl.exe (or that's defect). I couldn't start windows from the CD, I couldn't start it from another windows CD, nothing worked. Since I didn't have that many data on windows I decided to delete the partition and start from scratch using Boot camp. So far I tried to reboot probably 100 times trying out everything I found on all forums.
Using Disk Utility to check HD, run repairs, even erased everything on the new boot camp partition. That all works fine. But as soon as I restart from the CD to start the Windows installer I get a black screen.
Unplugging power cords for 30 seconds: no success
Holding down ALT/Option key: no success
taking the battery out: no success
running the FreeDos: no success (didn't start running the CD)
The solutions 1 and 2 suggested by LukeD: no success.
I'm pretty upset and lost right now. I do need a windows for running a learning software that wouldn't work on Mac. Now I'm trying to fix my Mac and I'm not able to learn anything at all.
Any suggestions?

My iMac 8.1 was slowing down and had permissions problems. I backed everything up, and then re-installed. Now all I get is a black screen. Power+D gives me a hardware error message: HDD-1336. Help!

My iMac 8.1 (10.6.8 ) was slowing down and had recurrent permissions problems, mostly with Java. I backed everything up, and then re-installed from time machine. Now all I get is a black screen which says I need to reboot. Power+D gives me a hardware error message: 4 MOT/1/40000003: HDD-1336 or HDD-1327. When I reboot from the OSX CD and start disc utilities everything checks out OK. When I reload 10.5.2 from the OSX CD everything seems to work OK and no more permissions problems. But then I loose all my email and safari stuff. Anyone have any ideas short of going back to my old PC?

Thanks for the help. No point in fooling around with it any more. Will I be able to use it as a monitor if I get a mimi mac?
Cheers. Don
No unfortunatley it's too old, you are referring to Target Display Mode which became avialble in 2009, your 2008 needs to have the HD replaced. I'd still do that if everything else is OK or you can simply buy a new MM and display or even a new iMac or an Apple refurbished iMac to save money.

How to How to install ATI Radeon HD2600 driver on bootcamp 3.0 windows 7 partition w/black screen problem

Ok....so i've posted this question in a different way, and i gotten several "scratch the surface" answers from people just saying to install "Ati catalyst", or insert the os x dvd and run set up.exe, and update to boot camp 3.1 or 3.2...while these all seem like great suggestions, I am finding myself needing more specific direction or "hand holding" so to speak.....here is the MAIN problem...
The Background/history
I used boot camp (3.0, and i found updates for 3.1 for imac and for windows, but can't find for mac pro, AND they all are ".exe" files which run on windows..which as you'll see is the big part of my problem...So I recently updated my mac pro (with the ATI Radeon HD2600 graphic PCIe card with 10.6.7 from 10.5.8. I created a single partitioned drive to install windows 7 professional 64 bit. The download software function didn't work (Thanks, APPLE for that poor level of support) so have to select the option that i have already downloaded, or have other media with the drivers already on it....i restarted with the windows 7 disk in....
The installation of Windows 7 Pro 64-bit
So the installation of windows 7 seemed to go flawlessly, was able to use my existing 23" hd apple cinema display (so somehow it has drivers that work with the graphics card, or maybe the motherboard's on board video components) and i select english, and install now, custom, blah, blah, blah...installation causes a few reboots, then restarts ultimately back in os x since that is the default boot os i use on this desk top and have to do the "opt" button to select booting in windows....so when i try restarting in windows, now using the actual boot drive on which i am installing it, it ran through another reboot or two, but then after that, my display goes black.... in the communities, the solution sounds super simple... "go download the ATI catalyst for the black screen problem....windows 7 doesn't have device drivers that work with the ATI radeon hd2600...no problem, just go download and install...."
The problem, re-emphasized : I cannot even finish the install for windows, because of this driver problem....i cannot see anything....I have tried to reboot in safe mode, and that then seems to invoke whatever basic drivers that do work, likely through the motherboards onboard video vs the actual graphic card, and the screen works and says that it's wanting to complete the installation, so i'm thinking awesome this is gonna work....and then.. "windows installation was not completed and cannot be completed in SAFE MODE, need to restart, blah, blah, blah" pops up...and forces reboot...so Safe Mode allows me to see, but won't allow me to finish the install of windows 7...and without completing the install i can't run (ranther I DONT KNOW HOW TO) any of the various .exe files everyone is telling me are the solutions to my problem...like update 3.1 and 3.2 bootcamp...they're all .exe files? not sure why, because bootcamp runs in 10.6.7 i thought, but whatever...it needs running Windows to execute...then the ATI radeon hd2600 driver for windows 7 that i downloaded from the site has an installation program that is an .exe file, which needs windows to run... Does this make sense, why i can't just use these fixes, that seem to be the only fixes out there....so can someone school me step by step here (not just the highlights) of how to update bootcamp, and how to install the ati radeon driver without having been able to complete the windows 7 installation because the monitor goes and stays black????
This is so very frustrating for the record...and any substantial help "not just go download this..." would be immensely appreciated.
Some other things i've been told to try that i've tried and nothing seems to happen as i'm told it will....
---I've been told to install the osx dvd and run "setup.exe" - AGAIN...it's an exe file...and 2 - when i put in the os x file it just wants to re install 10.6...so need more help if this is even a real solution to understand how to make it work...
---I've been told to update boot camp to 3.1 and/or 3.2 from 3.0, using Apple Software Update....Well, my software update is saying everything is up to date and there is nothing new to download at all, and when i reverify the bootcamp version it is still only 3.0.2...and again downloading the updates from www.apple.com/support/ for 3.1 and 3.2...all of those are .exe files...need windows to run them...again, refer to the problem described in detail above...
---I've been referred to the black screen on imac early 2011 thread saying it should fix my problem...and reading it it SEEMED like the most promising resolution...it involves creating a boot flash drive for windows 7 and an xml file that sets the imac drivers to auto install during the windows installation..and it got me farther than anything else..but still ultimately ended up in the darned black screen...my assumption is that it's because it's for imac and not mac pro so not ati-radeon specific drivers....ok....that's enough..please...anyone who thinks they can help...your help is desperately needed...thanks so much in advance!

hey Hatter, thanks so much for getting back...so just to be super clear...is there no way to install the drivers using an exe file given my current state? no way to do it with command prompt or something? if can make work with existing card, i'd prefer it...now when you say it's 'toast' how do you mean? it works well with the os x partitions and always has...so i'm not sure i follow, just want to be clear...
Now to your point of starting with only the one drive installed...so i would put that bootcamp drive in bay 1 and disconnect the rest...i'm not totally sure what you're suggesting the effect should be of doing this? just that i'm just installing windows without the bootcamp deal...but if windows 7 doesn't support the ati radeon hd2600, it still will go black screen no? or you're saying it will run video through the motherboard if it's the only bootdrive, and will run all the way through the windows install without trying to switch over to the hd2600? (slrry flr these questions..just really want to make sure i understand what you're telling me..thanks so much for your patience and help by the way...it's very greatly appreciated...your support is priceless!
So now, assuming none of the above is possible...referring now to the ati 5770 that you referred to...you mention it works with 10.6 well, and that windows 7 supports it ...2 questions on that
1) Windows 7 supports" meaning, out of the box windows 7 supports it? or will i have to install drivers still through some update, because again, if that's how i have to do it, then won't work, cuz can't start windows to see anything to install any drivers or run any thing at all...so it would have to just work with initial installation.
2)hardware wise for my Mac Pro 3,1...intel dual quad core xeon, blah blah....will this card work? it's a PCIe and should fit on my board no prob, etc?
