Corrupted/Flickering display

Over the last few weeks I've noticed that part of the window that displays the movie/clips is corrupted along the top and right edges. Display of the finished movie isn't affected, but it makes editing and composing very eye straining because the corrupted part of the display is constantly flickering.
Anyone else got this problem and found a solution?? I haven't tried re-installing imovie because I don't know how.

>An external monitor functions fine...
Thats good. The main thing there is no problem with GPU.
> I'll start with checking the cable connection to mobo, followed by a replacement inverter board.
I dont know if FL inverter can be reason for this. I dont think so.
Anyway, send some feedback. It will be interesting to know if you will be able to fix this.

Safari 3.2.1 With 10.5.6 Update = Corrupt Font Display

Since updating to 10.5.6, Safari is corrupting the display of certain small fonts, such as the "Compose" and "Preview" tab labels at the top of this Discussion "New Topic" window, and mail subjects in Yahoo web mail. The problem is more severe with small bold fonts. I have OS X's font smoothing turned off for font sizes smaller than 12 pt, and use the CRT smoothing style, as I prefer little to no font smoothing on my LCD monitor.
I've reset Safari, corrected duplicate fonts, validated all fonts, run DiskWarrior, FontNuke to clear all font caches, and even reinstalled the 10.5.6 combo updater; nothing has helped. If I make the font one size smaller, the corruption is mostly corrected. OmniWeb 5.8 has the same issue as Safari under 10.5.6; FireFox 3.0.5 & Camino 1.6.6 are unaffected, and render fonts as well under 10.5.6 as they did under 10.5.5.
I've booted my 10.5.5 backup to verify that Safari 3.2.1 and OmniWeb 5.8 had no font display issues before the 10.5.6 update. The 10.5.6 update was the only software change made on my system since the 10.5.5 backup I used for comparison.
Anyone else seeing strange font display in Safari under 10.5.6? I think you'd have to minimize OS X font smoothing as described above for the problem to become visible. I'm out of possible solutions, other than hoping for a fix in 10.5.7.

Well, for the time being, I'm just going keep 10.5.6, and use revised font smoothing settings: "Automatic" style, and "turned off" for font sizes 10 pt and smaller. The reason is that I did a little more investigating, and found that the distorted small font issue affects the entire system, including the Finder, not just Safari.
I checked my G4 MDD that's running 10.4.11 on two 23" monitors (1920x1200), and it has the same issue as my G5 running 10.5.6, if font smoothing is turned off. So, this is apparently a long standing OS X issue that, for some reason, never affected my lower resolution G5 system driving a 20" monitor (1680x1050) until the 10.5.6 update was installed.

A536 corrupted screen display

Hi,
Good day!
Anyone can help me with my A536 phone?
It has corrupted screen display (with horizontal lines)
Please see attached pictures for your reference.
Thanks,
PJ

Factory restore would restore everything back to default, note that factory restore would delete all data and apps.
This would narrow down if there are any apps which could be causing lines issue. Also I would suggest to do a System Update first. If that does not help then factory restore. If factory restore does not help then service center.

Flickering Display Successes

Since the other threads are getting so long with people saying the same thing, i thought i would round them all up and start this one for people who have fixed thier flickering display to share with others how they did it. Hopefully this should be useful for people who havnt fixed theirs yet.
So please don't post unless you have fixed your display (or apple have).
Il start... I downloaded the latest battery update and it seems to have worked.

I have the same problem (but no solution I'm afraid). If I move the screen back and forward a few time I can find a position where the flickering stops. I'm guessing this is a cable or connector problem. For me, it's an irritation that doesn't warrant paying the money to get it fixed, since my PB is 3 years old and if the screen gives up the ghost completely then I'm ready to buy a new laptop.

IPhone 4 Flickering Display and Unresponsive Screen

My iPhone 4's screen was not responding when I tried to swipe it or anything of that sorry - texts and notifications from internal apps kept coming in as they normally would however. After backing up the phone to my laptop, I manually shut it off using the power and home buttons, which was successful. I let it sit for a minute and then turned it back on, and upon looking at the screen noticed that the display is flickering just the tiniest bit (it's definitely enough to notice, though.) Any suggestions on how to remedy this?
Saw in previous discussions the suggestions to turn off auto-brightness and the problem would be solved, however I already had the auto-brightness turned off when the flickering occurred.

Pink flickering display problem

Hoping someone might be able to help. The screen on my Powerbook G4 15" 1.5Ghz (OS X 10.4.11) is a dark pink (almost black) and flickers. You can still just see the desktop and icons but only very faintly. Originally, it went pink only on start-up (or when the screen woke from sleep) when it would gradually 'warm up' to white. I now can only use it in clamshell mode with a Studio Display which doesn't have the pink problem . From reading other posts, I gather that this seems to suggest that there isn't a problem with the logic board, but maybe the backlight has gone, or a cable, or the inverter needs replacing. Has anyone had the same problem, and if so was one of these that was the problem, and were you able to fix it? I've looked at various online diy repair tutorials and reckon I could handle most of them, but I'd like to be as sure as possible that I'm replacing the rigt parts before undertaking the project. Any suggestions gratefully received.

Peter: I'm sure I wrote a reply to your post the day it first appeared here, but I guess I must have hit the Back button instead of the Post button after composing it. Sorry!
The fact that an external display works fine for you indicates definitively, as you've guessed, that your logic board (including the GPU) is working properly. The problem is with your display backlight. An old, tired fluorescent backlight tube is typically pink or reddish until it warms up, and a very old one may stay pink or reddish all the time. If your backlight is flickering, it may never warm up properly, so that may explain its continued pinkness. The flickering may be caused by a failing inverter (which supplies power to the backlight) or by a damaged backlight cable (damage can be caused by chafing where the cable passes through the display hinge) or, much less likely, by a failing backlight tube. In your shoes, I would begin by replacing the inverter to see whether that eliminates the flickering. Replacing either the cable or the backlight tube is much more involved, and I don't recommend those as DIY procedures.
Sarah: You haven't told us how your display is misbehaving, so I don't know whether or not my advice to Peter is on target for you too. Exactly what are you seeing on your built-in display, and what do you see when you connect an external display?

Corrupted font display under GNOME 3

Why do my fonts suddenly go from displaying normally to looking like this under GNOME 3?
The same thing happens under Cinnamon. Other desktop environments don't have this problem.
I'm using an ATI Mobility X1400 notebook video card.

Hi Unia,
This problem predates the recent Fontconfig changes.
By "suddenly", I mean that at some random time after I login to my GNOME 3 session, the fonts go from normal to corrupted. It could be 30 seconds or it could be 30 minutes.
The fonts don't always stay corrupted, either: for example, at another random point in time, my XChat fonts will go back to normal, but my VirtualBox and Chromium fonts will still be corrupted. If I logout and login again, the problem is fixed, until they decide to randomly break again.

Graphics corrupted / garbled display on Core Duo MacBook Pro (ATI)

My first-generation (Core Duo) MacBook Pro (with ATI chipset) is having video problems.
When this happens, the graphics become corrupted / display becomes garbled and the computer freezes shortly afterwards making it basically unusable. You can just about follow a garbled mouse pointer around, but it is unresponsive.
The only solution is a hard reset (power button for seven seconds).
Has anyone encountered this problem?
At first, I suspected that the computer was overheating as it seemed to occur only after prolonged use - but in the past two days, it could freeze immediately at login screen basically making it completely unusable.
Apple Hardware Test (on original CD) says "No Problems Found", but I still suspect hardware trouble as this only began occuring a week or so after my computer had the left fan replaced (it stopped working after an earlier problem in January at the Apple Store in Highcross Leicester.
I suspect something ELSE is wrong and that it requires service again, so am planning to go to the store in Birmingham on Sunday (which is closer to me -- I went to the Leicester store last time). What should I ask Apple to look at? The graphic corruption occurs even when running right off the Leopard CD, or even on the Apple Hardware Test!

Hi - thanks for your help with the issue. Just as an update, I brought my Mac in for service on the 8th February at the Apple Store Bullring – and oddly, it worked perfectly in the Store. However, I showed them this thread and the pictures they had – and they replaced the logic board and apparently it's one of the costliest parts ever possible to place, shockingly expensive that it's like the cost of a new laptop! However as it's under AppleCare (well, higher education parts and labour warranty) it was covered. Phew!
I got my Mac back today, and so far, it appears to be working perfectly (though as the graphic problems were intermittent, I'm making sure I do backups!), and fingers crossed, I should now have a working Mac once again!

Wicked bad Flickering Display in 2009 MacBook

On Memorial weekend of this year (2014) I went through airport security with my computer. I've done this before, but when I got to my destination and turned my computer on the flickering and weird flickering stripes on the left side were there. I did not drop it or do anything else that I can think of that would have damaged it. Oh yeah, I have a MacBook 2009. I don't know about any other specs and since I can't see my apple menu icon thingy I can't tell you more. I started to check out buying a new monitor (my husband did this for his Dell) and then I began to wonder if it is the monitor or maybe something else, something internal. I am obviously not a computer savvy person. I need to do something quickly (finally) so I can display photos for a special occasion. Any thoughts?
Thank you!!
MacBook

You could contact an Apple Store with Genius bar for a diagnostic test to see what
is the actual defect behind these symptoms you've noticed; they can give you an
estimate on costs to repair the device. In several regions (esp US & Canada) the
Genius bar diagnostic testing is a free service...
http://www.apple.com/retail/geniusbar/
Find an Apple Authorized Service Provider
Visit an Apple Retail Store
http://www.apple.com/support/contact/
This is about the best advice a person can offer in this regard, since there appears
to be a hardware defect and there are more than a few parts that could cause it.
Hopefully this helps resolve the mystery, at any rate...
Good luck & happy computing!

Corrupt result display during testing.

I have a custom UI running TestStand sequences. The sequences call my COM DLL to display results during testing. The results are displayed in a CWnd derived list. The results scroll in the list. If anything interacts with the list (message box, or mouse) the list becomes corrupted (blank lines etc), and eventually the process crashes. This occurs on win2000 but not on WinNT. Any similar problems, or suggestions?
Also, the COM DLL dialog is run in a user interface thread.

I have done something very similiar to what you are doing. I have an MFC User interface that runs test sequences. I also have a DLL interface to an active X automation server that the sequences call. The server also displays test progression information sent directly from client applications that the sequences call. I also had problems with my displays working correctly when we moved from NT to 2000. I resolved the problems by upgrading to MFC service pack 5.0 and rebuilt all my components in Windows 2000.
I hope this helps,
Steve

10.4.9 and corrupted screen display

I updated my 1.83Ghz MacBook Pro to 10.4.9 today, but when I wake it from sleep, the screen display is severely corrupted. I need to hit the power button, and get it to sleep/wake up again before the screen clears and the machine is usable. Anyone else notice this?

I am experiencing the same issue on a new MacBook Pro after going to sleep.
However, you can actually enter your log-in details (if you've set up log-in after sleep under security), and access the Finder, but the screen is still corrupted.
However, if I close the lid, and reopen, the problem resolves itself, i.e. the screen is no longer corrupted, and I can log-in as normal, i.e. so, you don't need to power cycle.
Previously, I tried resetting P-RAM, and that also seemed to temporarily resolve the issue, but it occurred again about a week later.
I have a feeling it may be something to do with the "Safesleep" file being corrupted, and I have tried to disable that via Terminal using the following command (usual disclaimer about making changes via Terminal): sudo pmset -a hibernatemode 0
(NB. default setting is 3 if you want to turn this feature back on).
I tried that yesterday, and the issue hasn't re-occurred yet, but will keep you posted. I suspect that isn't really the issue, because I'm not always trying to recover from the safesleep file, i.e. just normal sleep after a few minutes without any power loss.

Pismo with flickering display

My Pismo is loosing its display! The problem is that it flickers sometimes. The video image appears bright but the image is displaced from side to side or totally unintelligible. The following can cause the display to flicker:
* closing and opening the display is 100% likely now to cause flickering from just a little to whole screen illegable.
* clicking on keys can cause slight flicker, as can the track pad.
But, my wife discovered that if you move the display forward or backward until it is good, then you can move it to the desired position and use it that way for several days so long as you don't move it again.
This Pismo is my favorite computer to date, so I hope I can keep this from killing it.

Paul,
I am not sure what to advise at this point. You may have a damaged ribbon cable where it enters the connector at the logic board. If the antenna cable is too short, somebody may have already been into the display and contributed to the problem. Possibly the data cable was also a little short and stress has damaged it. If any part of the ribbon cable is damaged, it would require replacement; this would entail removing the display and partial disassembly of the display to access the cables on the back.
If the data cable and/or connector for the data cable on the logic board are at fault, you are looking at some dollars for repairs. This link below gives an idea of what used parts cost:
http://www.ifixit.com/Products/G3-Pismo/Displays/10/6
If for some reason the male connector on the logic board is faulty, you would probably need a replacement board:
http://www.ifixit.com/PowerBook-Parts/G3-Pismo-Logic-Board/IF106-020
If a certified tech made the repairs, it may not be worth the money.
I cannot explain the scrolling issue. You could connect to the external again and see if in fact there may be something wrong with the VRAM and/or graphics chip that did not show up the first time.
You are at the point some Pismo owners reach...you really like the powerbook and are now facing a decision...to repair or move to a new(er) platform. At some point, one moves on...possibly you are there now.
I hope I have been helpful and thank you for your gratitude.
