Powerbook screen issues with blue pixels replacing colors

This is my Grandma's computer. It is a Powerbook G4 1.5 GHZ running mac os 10.5.6. It took a trip and she might have possibly dropped it. The issue is with the LCD display. Blue pixels seem to be coming on too much, especially on the edges of the screen. BASICALLY, some spots of color seem to be replaced by blue pixels. Is it a mother board issue, an LCD issue, or a display cable issue? I want to try hooking up an external monitor, but haven't done so yet.

The external monitor would be a good thing to try. If the pixel artifact also appears on the external, it would imply a problem with the graphics chip. If not, it would imply a problem with the internal display or its connections. When pixels are involved, it is often an internal display problem.
If you have the original install discs, you could also try running the Apple Hardware Test and see if anything shows up in the form of an error code.
Good luck!

Is iphone 4 having issues with Blue tooth?. I have checked four iphone brand new sets from different location. Not detecting other devices

Is iphone 4 Having issues with Blue Tooth connectivity ? Last saturday i have bought up iphone 4, when i checked that device blue tooth was not detecting the other iphones. I went to apple store in Ottawa. They checked with their Mac computers. They said Yes this iphone is having problem. Please exchange it on the store you bought up. I have exchanged that iphone with brand new, again same issues...
iPhone is not detecting other devices with Blue Tooth. I have checked with other two. they having same problem.
Please tell me, What apple gonna do with my iphone now ? Should i keep it ? or cancel my contract with cell phone company. As i am sure they not going to replace it again or gonna make excuses.
Waiting for replies [email protected]

I have upgraded my iphone 3 to a 4. I just recently discovered that while the iphone 3 automatically discovers bluetooth but the iphone 4 does not (couldn't discover any bluetooth). My bluetooth is Jabra SP200. It turned out, there are other steps to take with the bluetooth device to pair with the iphone 4. As stated, iphone 3 detected it automatically. But w the iphone 4, I had to press and hold the answer button of the Jabra for it to pair with iphone 4. Call the bluetooth manufacturer directly and check with their alternative pairing procedures.
Hope this helps.

Is anyone having any uneven or discoloured screen issues with iPad mini or iPad 4th Gen?

Hello, in view of the fact that many users had screen discolouration issues and uneven backlight issues with the iPad 3rd Gen, I wonder if those issues have been sorted out. Has anyone here had any screen issues with the iPad mini, or the iPad 4th Gen?

No.

Powerbook screen - weird fuzzy flickering pixels

Hi
We have a Powerbook that has suddly developed a problem with its screen.
At random times, red/pink shimmering pixels will appear.
Here's a photo of the screen: http://www.v12digital.com/powerbookg4screen.jpg
They will just appear at randon, and can stay for a few seconds, or until the computer is rebooted.
I ran an extended hardware test, and everything passed. I've also reinstalled OS X 10.4 using the Erase & Install option.
This seemed to fix it, but about an hour later, the fuzzy pixels appears again.
I've seen other messages about weird screens, but they're all different to this.
I would appreciate any help with this. Any ideas as to what it could be?
Thanks.

Greetings ...
I'm no expert so can't suggest much. I have just noticed that my pixel and screen issue although recent (past 3 months) aren't nearly as severe or consistent as others in the forum. I notice the issue perhaps more when operating on battery power, text iChats, and when I have many applications open/running. My inquires lead me to believe that high temperatures have caused issues with other brand laptops. However I'm still not convinced its software and hardware related.
I have recently downloaded the iStat Menus from the Apple downloads page (free) http://www.apple.com/downloads/macosx/systemdiskutilities/istatmenus.html. I chose the menu bar option, however there are two others to choose from including a widget. With this little utility you can monitor fan speed, temperature, cpu usage among other parameters. My fans are capable of spinning up to 2800+ RPM which I believe is adequate for cooling.
Next I downloaded Andrea Fabrizi's G4 Fan Control http://www.andreafabrizi.it/g4fancontrol/. A small (free) utility that allows you to see the temperatures of each CPU sensor and the temperature at which the fans are set to begin cooling. Best of all you can select different temperatures (lower/higher via a slider type control) for the fans to begin working, or as I've done when working in Illustrator and Photoshop while streaming music ... just slid the fan controls all the way to the left turning the fans on max rpm/cooling. I watched the cpu temp drop from 144˚F to 116˚F in about 60 seconds which is amazing. The default settings only allowed the fans to spool up to 1700 RPM which provided cooling, but nothing to drop the temps more than a few degrees. It took much higher temps to get the fans to spool up to 2800 RPM. Now I run my laptop at very "cool to the touch" temperatures.
I still have not discovered if the pixel problem is related to heat, however, I have direct control over the laptops temperature which in itself has made it more comfortable to use and hopefully will extend the life of its components.
Hope this info is helpful in diagnosing your issues ...
Cheers

Notebook screen issues with green stains

Hello:
I currently own an
HP G62-355DX Notebook PC
[Personal Information Removed]
P/N: XH068UA#ABA
running Windows 7 64-bit
All of sudden (not gradually) green "stains" appeared on my notebook's screen as 3 circles one around the other, sort of like a "bulls-eye" and when I try to run a program in full-screen mode the screen goes bezerk and nothing is readable. I thought it was an issue with the cable connecting the screen to the main-board but I've been told the issues would be different.
These green "stains" or pixels affect any program running or the screen itself, even the Windows 7 starting screen and the HP logo when the notebook is turned on by making the letters on the bottom-left corner unreadable.
After contacting HP at Peru, where I currently reside, I was told the model was not sold here and that I had to contact US support. They said that it could be an issue with the screen itself that could require maintenance at an HP office. And also told me that it was unlikely for remote support to be able to fix the issue.
It is still not over a year before I got the notebook so I'm guessing the warranty is still available.
Would I be required to e-mail the computer back to headquarters in hopes of it being repaired? Is it possible that it could be dealt with at your offices at Peru (I will still be residing here for quite some time).

Screen Issue with HP G7000 laptop

Hi there,
I bought a second hand HP G7000 laptop preinstalled with Windows Vista Home Premium x86 a few days ago, the problem with it was that the screen wouldn't light up even when plugged the laptop was plugged in using the AC adapter which I also had to buy seperately as the original one was misplaced and only cost me £10 for a compatible one off the Internet, the screen wasn't shattered and showed no signs of wear and tear, I took it to my local PC repair shop for £40 in which the contacts behind the screen needed connecting back up and with a little soldering for some other parts of the repair, however when I tookit back to my place the screen lit up fine in which I decided to perform a factory restore to make it feel like it was brand new and that it belonged to me. After restoring the laptop successfully, I noticed that a lot of stuff was a little out-of-date and decided to update it to make it compliant with the latest security fixes as well as the latest bug fixes i.e. to upgrade to SP2 etc, however upon updating and turning on the laptop every so often the display kept going funny i.e. black and white and wouldn't display anything clearly in which I had to keep forcing the laptop to shut down with using the power button in which I don't like doing as this will corrupt the hard drive eventually, however upon researching this problem on the Internet I stumbled across this forum thread http://www.techsupportforum.com/forums/f108/hp-g7000-screen-issue-529809.html using Google describing a very similar problem to me, the problem not only seems to be with tilting the angle of the screen but also the surface in which the unit is placed down on, I've tried various surfaces including my USB fan cooler, glass and wood and all produce various results from time to time. So I guess the answer is to place the unit down on a flat surface that isn't shiny and screen not tilting when using the laptop? I thought the purpose of a laptop was to make computing mobile regardless of what surface you place the unit down on and what angle you have the screen at. Your feedback and suggestions would be much appreciated.
Kind regards,
RocknRollTim
P.S. I also suspect that the problem is related to interference and lighting conditions as well as heating conditions and the battery as the battery sometimes retains its charge whereas sometimes it doesn't and have to use the AC adapter when this happens, don't know whether flashing the BIOS has helped the battery to retain its charge though.
This question was solved.
View Solution.

Hello @RocknRollTim,
I understand that your notebook computer is experiencing an issue with the display screen as well as keeping a charge with the battery, and I would be happy to assist you in this matter!
To further diagnose the integrity of your computer's battery, I recommend following this document on Calibrating the Notebook Battery (Windows Vista). This should help re-synchronize the battery with your notebook.
Because the display intermittently stays on the screen when moved a certain angle, I believe the display panel cables are defective. According to the Maintenance and Service Guide for your computer, this part can be replaced with a camera (462455-001) or without (454932-001), and can be found from the multiple vendors below:

Transparency issues with INDCS3 and Pantone color

Running Windows XP, Serv Pk 2, Creative Suite CS3, All updates.
Heres the deal: We are having problems with PDFs printing and Ripping when using transparencies and drop shadows.
Issue 1: INDD CS3 file with transparent PDF placed as image. Separate frame filled with paper, stroke and drop shadow placed under trans PDF file. Filled frame areas of percentage tint using a PANTONE color used on same page. File re-PDFed (compat to v6) and file printed correctly to XEROX 7760 and HP color. PDF views correctly. Recommended ordering policy applied to all layers as to keep drop shadow below text. PROBLEM: User running Acro 7 to printing to same color printers, receives copy with color tint areas missing.
Issue 2: INDD CS3 file with solid Pantone color on background. Several text frames layered above. Under text frame a solid box with SOLID Drop shadow. PDFed using Acro 8. PROBLEM: User's RIP and DIGITAL presses do not recognize the drop shadow? White knockout box appears in this area.
It seems that CS3 is handling transparency issues differently and/or that Acro 8 (compat to v6) is doing something different. The Acro 8 users have no problem printing or PDFing.
Could this also be the "known issue" of transparencies and PANTONE colors? We are testing out converting all the colors to CMYK.
Please respond at your earliest.
KEN PANTHEN, Albany, NY

Ken,
If your final output is to the Xerox, which can't print Spot colors without converting them to CMYK, you should use process colors instead.
Also, read the articles from InDesign Secrets:

Weird screen issues with safari

Hi, I just got a refurbished 15" macbook pro...not retina, but I believe it's a 2012 model. I'm experiencing a couple weird issues with it. So far, they seem to be exclusive to Safari, but I'm not sure yet. Haven't been able to recreate the same problems in Chrome or other programs. The problems are:
1) When filling text into a blank or box...as in a google search, or typing a facebook message, the text I am typing will often disappear or be invisible until i move the cursur to someplace else...then the text will show up. Words at a time can be invisible. Like I said, so far, I'm only noticing this in Safari, not Chrome, but I'll have to test with Chrome some more to know for sure.
2) Sometimes portion of a page will be misplaced on the screen. For example, if I'm on Safari, and reading a news story, the left side of the page will look normal, and the right side of the page will look normal, but they won't match in the middle....I'll be seeing text from the beginning of the article one the left side, but from the end on the right side as though only part of the page is able to scroll. Again, this is only in Safari so far.
Both these issues (which I assume are related) have been happening since the first day I got the computer last week and it hasn't been dropped or had anything spilled on it or anything. I'm well within the warranty period, but this problem may be hard to recreate immediately if I bring it in to a store, so I want to check here first and see if anybody has any ideas.
I'm hoping this is a simple known bug with Safari that will eventually be fixed and not a problem with my new computer. It is enough to have me second guessing my decision to go with a refurbished model, but I'm probably just paranoid. I'd appreciate any info that anyone has. Thanks!!!

I could suggest a reset, but I don't believe that will do much good.
First, I would contact your local Apple Store, should you be near one, and see if the Genius Bar can solve the problem quickly.
Second, if they require repairs, you can use their expertise; or, you can use iPod Juice - a business that's more competitive. The latter is where I had my repairs done; email them for fees and services.

Windows 7 Blue Screen Issues With Alt-tabbing From WoW

As the title says, lately I've been having blue screens which are mostly caused by wow.
Previously I've had the occasional bsod (once a month or so) when alt tabbing, but it was pretty rare. However recently, I've had something more like 1 a day, usually caused by alt tabbing out of wow. It seems the longer I'm alt tabbed the more likely it
is to happen. I haven't experienced the same problem with any other game, although the occasional monthly ones usually happen when I'm changing my music as I alt tab out of League of Legends.
I downloaded bluescreenview and it appears the cause is some combination of win32k.sys as well as ntoskrnl.exe Based off the fact that it is happening more with a more demanding game, I'm guessing the problem is
most likely due to a bad stick of ram, but I'd like a second opinion.
I'll attach a few of the most recent dump files (the one today is slightly different than the ones last week which seems slightly odd).

We have two consistent bug checks:
SYSTEM_SERVICE_EXCEPTION (3b)
This indicates that an exception happened while executing a routine that transitions from non-privileged code to privileged code.
This error has been linked to excessive paged pool usage and may occur due to user-mode graphics drivers crossing over and passing bad data to the kernel code.
BugCheck 3B, {c0000005, fffff80002e5301e, fffff88008945c70, 0}

^^ The exception occurred in nt!ExEnterCriticalRegionAndAcquireFastMutexUnsafe. This is a routine that first enters a critical region, and then acquires the specified fast mutex for the calling thread.
PAGE_FAULT_IN_NONPAGED_AREA (50)
This indicates that invalid system memory has been referenced.
Bug check 0x50 usually occurs after the installation of faulty hardware or in the event of failure of installed hardware (usually related to defective RAM, be it main memory, L2 RAM cache, or video RAM).
Another common cause is the installation of a faulty system service.
Antivirus software can also trigger this error, as can a corrupted NTFS volume.

Right, so the code wanted to write to 00000000`00000020 which as we can see above is a completely invalid address. The 1st parameter and cr2 however note we failed writing to address
fffff900c25efcf0. This does not make sense, and is essentially not logically possible.
The hardware was told to write to 00000000`00000020, and the hardware came back and said 'I cannot write to
fffff900c25efcf0'. Another way to think about it is if you kindly asked the waiter of your table for more water, he writes it down, but comes back and says 'I'm sorry, but we're all out of coffee'.
1. Uninstall any/all installed Asus bloatware, I for example see Asus PC Probe, and AI Suite.
2. Remove and replace avast! with Microsoft Security Essentials for temporary troubleshooting purposes as it may be causing conflicts:

3. If the above fails, you have faulty RAM.

How can I resolve issue with Blue screen feature?

I am able to use the green screen feature ( using a green screen background), but when I use a blue screen background and I use the blue screen feature, it does not work. The background on the video with the blue screen turns RED and I see that video and not the selected background with the special effects.
any one has seen this before?

Screen issue iPhone 4 - pixel drop

I have had a replacement iPhone 4 for just over 12 months now (around 27th January last year I had it replaced due to a small crack on the back casing near the camera, was due to the official bumper putting pressure on the camera corner). And recently I have noticed that there is a small mark on the screen when viewing some pages with certain colours. As I bought my original iPhone 4 on release day, I am not covered by AppleCare. I was just wondering if anyone knows if they can do anything for me at the Apple store. The issue is toward the top of the screen and is like a small line of pixels that are fine with deeper colours, but have problems with whites, blues and lighter shades.
If anyone has any ideas, please let me know. I am not really willing to pay to get this problem solved as I think the price for repair is way too high.
Thanks.
Damien.

i dont think thats what hes talking about if you look closely at the bottom right hand side of the image there is a redish circle that looks burned into the screen and another rainbow looking one just above it
as to the op I would take your phone into a apple store for replacement seems like there is something wrong with your screen

Screen Issues with MacBook Pro (Static Lines)

Hey guys. I aam having problems with my Screen/Display on my Macbook Pro.
Static lines appear aprox 1/3 of the way in from the right side. The lines run horizontally about 1 inch in length and running vertically all the way down the display. A screen shot shows a normal working display. Took a pic of the problem:
I cannot run hardware tools. My computer did not come with a disc and I know they are only a shipping charge but I do not have even $5. I am a student and this is my only way to do my schoolwork. The Screen (inner display and outer protective screen) was replaced by Apple in May '12. The 1 yr warranty ran out in June '12. When the screen was replaced it started doing this as well, but had not gotten this bad. There are now 2 where there was only one yesterday. I am wondering if it may be the cable as moving the display often fixes or produces the problem. I know the cable is not very expensive and not to difficult to replace.
Here is the info on my Mac:
Nice Name:
Machine Model: MacBookPro9,1
Name: MacBook Pro (mid 2012) 15 inch
Family name: A1286
Model Number: MD103

Group2: Pro

It is getting worse in the sense that it is occuring more often and taking longer to resolve. Moving the laptop lid/display would typically fix the prblem in the past but now it is hit or miss. Even vibrations will cause the issue to occur or resolve. We are leaning more towards the issue being a cable and not the display. Since taking a screenshot produces a pic without issues I would gather that the video card is fuctioning properly. I welcome any comments on this.

Grey screen issue with 10.5 & 10.5.1 - bad experience with Leopard

Here's a quick overview of my bad experience with installing Leopard:
*1st attempt:* Upgraded Tiger 10.4.10, was greeted with the blue screen. This was an APE issue.
*2nd attempt:* Archive and installed above install. This is where the continuing issue first occurred. The issue being on the first or second reboot after a 'successful' installation, I get the grey screen and spinning gear loop. In verbose mode I see this recurring loop:
Mez com.apple.launchd[1] (com.apple.nDNSResponder |xxx|) : posix_spawnp("usr/sbin/mDNSResponder", ...): No such file or directory
xxx = incremental value, it adds 1 each time the error cycles, which happens roughly ever 10 seconds).
Additionally, Disk Utility reports this error: Error: The underlying task reported failure on exit.
*3rd attempt:* Erase and install. Same issue as 2nd attempt occured.
*4th, 5th, 6th attempts:* Bought a brand new hard drive to replace the old one. This was an idea that was raised on another one of my threads. People thought I could have bad sectors. Tried upgrading and archive install from 10.4, no. Erase and install, no. Same issue as before.
*7th attempt:* Tried swapping out the RAM from a friends MBP (who has successfully upgraded to Leopard). No, same failure as before.
*8th attempt:* Tried using his Leopard disk. NO!
*9th attempt:* My last attempt so far... Erase and install, then applied the 10.5.1 update. It all went well, but it always has, until the point where I reboot. It successfully rebooted once, but to be sure all was fine (before using the migration assistant) I rebooted again... Oh what a surprise, it doesn't work anymore. Same enraging loop.
*Any new ideas people, I have faith that there is some genius out there who can provide me with a solution. I will love you forever if you can help me.*
*Quick question:* Do other people see the dialogue box that appears before the computer restarts...
"Updating Boot Caches - The Boot caches are being updated, the system will shutdown when this task is complete" (It's sort of along those lines. I don't have enough time to write down exactly what it says)??
Oh well, back to my newest backup (10.4.11).
*Fingers crossed for 10.5.2 :D*

THANK YOU!!! At least preliminarily...
I've spent the last three hours researching and troubleshooting my greyscreen dilemma, and your post is the only one that seemed to work so far.
I installed Leopard 10.5 onto my G4 Dual 1.25 Mirror, successfully restarted after the install, then had glitchy problems including being unable to run Software Update or even run the Leopard Update after downloading it from the apple website. So I restarted the computer (after removing the Install DVD and shutting the drive door) and found myself stuck at the grey screen with the spinning ball.
Nothing worked. I couldn't do anything to get it to boot.
After researching, I booted into single user mode and ran mount -o rw,remount / # (from this thread: http://discussions.apple.com/thread.jspa?messageID=5796214&#5796214) and when I exited and it began to boot I saw it get stuck at mDNSResponder line prompt, repeating the line prompt every 5 seconds or so and never getting anywhere.
Then I found your post and changed permissions as you mentioned, exited and it booted up successfully. I then immediately ran Software Update and installed the Leopard 10.5.1 update and now all is well again.
Insane for this to be required. I barely know what single user means and would have sent this computer in to Apple if I hadn't found your solution.
Hopefully the next person who searches on this problem will find this and save themselves a horror story too. Thanks again.

Green Screen issue with an flv file

I am attempting to create a Green Screen were I walk out onto my website and speak to the viewer. Everything looks good and plays within Premiere but after exporting and placing it on my webpage a black background shows instead of the background being transparent. can someone help with what I am doing wrong?

> and are flv files the only ones that I would run into this with?
There are other kinds of files that can include alpha channels (transparency). Just so that you know what to look for, QuickTime and some other formats require you to specify the inclusion of an alpha channel from a color depth or channels menu. In some cases, a plus sign (as in Millions Of Colors+) denotes an alpha channel. Similarly, choosing to output to 32 bits per pixel implies an output depth of 8 bits per channel for each of four channels: RGBA (where A is for alpha).
But, yes, FLV with video encoded with the On2 VP6 codec is the main format for web video that supports alpha channels.

Green Screen issue with reflections (Primatte Keyer)

Hi together, as I noticed lately I unfortunally got some reflection issues at this singing bowl in the back. I'm looking forward to chroma key it using primatte keyer.
It looks like I got a serious problem there and I'm looking out for a little help.
Would be so nice to get a clue or two to keep on working on a solution. My problem is - the girl is moving a bit later - so a simple mask would'nt work. I think it would be the best to key the full singing bowl and replace it with an image later.
I also have footage of the setup without the girl sitting in focus.
If I remember right, there was an different keying technice were I can "erase" the full background and when the girl is mooving to the focus everything else is keyed with exeption of her. But I can't remember the correct terms or keywords to look out for solutions online.
Thanks in advance - hope I will find a solution :-/ .. maybe on or another of you guys is able to share a clue with me.

After carefully looking at your shot I would mask the bowl first, put it on top of the original footage, use color suppression on the bowl to remove the green, then nest that comp in another comp, pull the key using the nested (pre-comp), then put the original footage above the keyed comp then use rotobrush to mask just the part of the girl that passes in front of the bowl. The project would look something like this:
I used Keylight's Foreground Color Correction to supress the green on the masked bowl layer. If the camera is moving you can track and stabilize the shot, use a track matte, then re-introduce the motion to the track matte and remove the stabilization to keep things lined up.
Pardon my funky orange solid background replacement, but I think this is the way to do the shot with the least trouble.
