My iMac G5 17 inch LCD monitor has green pixel burnin after internet browsing for several hours


I have placed this thread inside of "Consumer Hardware & Components," because I think that my topic is best related to LCD monitors, and I think that "Consumer Hardware & Components" seems to best represent this issue.


After browsing the internet for several hours at a time, at the top left of that part of the screen where my browser's webpage viewing pane is (roughly 1.5" down from the top of the screen display), a very slightly greenish line indicating the line border between my browser's webpage viewing pane and my browser's tabbar (which is black due to theme installation on my browser) appears. Once it appears (might take 2 hours first), it gets quite visible after 2 hours, and then seems permanently burnt in after a total of 4 hours. This problem has been getting increasingly worse for the past two months, when it just first started out as a faint discoloration. Yet before two months ago, I had been fairly active with web browsing, and was extremely active with web browsing for hours straight last summer with no pixel problems. Luckily when I first turn the computer on and use it for 2 hours or so, there is no evidence of screen burn-in.

I have nearly always used to set my monitor to dim and then go blank after 2 minutes of use so that the piezoelectrics do not need to do so much work (in contrast to leaving the monitor on 24/7 like I suppose some people do).

I have heard about LCD burn-in being not possible, because it's an LCD, unlike with a CRT, but I am personally witnessing LCD-burn-in with my iMac G5 17" monitor. So, after researching the topic online, I had heard about individuals setting the display to maximum brightness and then flashing a screen-covering animation of entirely black or white frames at a fast rate to correct the problem, but that has not been too successful for me.

What else can I do to reverse the burn-in?

I would prefer to not have to replace the screen, as I doubt that I can do that.

You describe the problem as being a line invariably between the webpage viewing pane and the tab-bar...

also, you mention using a theme, but don't mention which browser, OS version, or anything else.

Stupid question:

what happens when you move the window?

LCDs can and do burn in, but it doesn't work the way you've described.

Do you have AppleCare? It sounds like your iMac is defective.

Well......

iMac G5 1.6 GHz
Mac OS X 10.5.3
Firefox 3 beta 5 with NASAlaunch theme
1.25 GB RAM
80 GB Hard Drive
AirPort Installed

When I move the browser window, the seemingly "burnt-in" stuff on the screen stays there, and it looks like a sorta fuzzy thin line.

I have to put the monitor to sleep for maybe 10 minutes to get the discoloration/burn-in to go away.

Could it be the light source behind the LCD?

Still an Applecare problem though.

I have no idea if it's the light source.

Behind that portion of the monitor where the line shows up is the hard drive and the case airholes.

I don't have AppleCare.

Any possibility you can take a picture of the line?

Alright well...


here are some pics:








I don't understand why so many details of me are needed. Haven't people seen LCD burn-in by now and know what to do?

Well once again, I have had to go back to doing research:

-
Yes, Virginia, There is “Burn In” On LCD Flat Panels � HDGURU.Com
-

Apparently this is called LCD retention (rather than burn-in).
But anyways, I guess that's about it then.

Apple calls it "image persistence."

According to the article, it's not permanent when it comes to LCDs. Turning the display off for an amount of time, or, playing a movie will fix it.
