Unfortunately, that sounds as though it could be a graphics card issue (and that card is soldered onto the logic board, which would necessitate a replacement of the entire thing). In order to find out exactly what it is, I'd suggest making an appointment at a Genius Bar near you - that service is free. You would then know what it is and get an estimate for the repairs - after that you can make a decision as to the best way for you to proceed.
I am going to try and file a claim with American Express and see if they will cover it. Unfortunately there is no apple store anywhere near me. There is a certified apple store (Simply Mac) I will try and take it there or the other man that works on Macs in town.
Could it be anything else? And if it is my graphics card/mother board would that permanently damage my display (guessing that would need to be replaced also?) I was going to get Applecare around the year end and I forgot. What a dummy.
Good idea trying the credit card - you may need something to prove the damage, such as an estimate from the Mac store.
In the meantime, you might want to run the Apple hardware test (it's not foolproof though) - follow the directions exactly and run the extended test:
Not sure if it will pick up on a graphics card defect, but it may be worth a try - make sure you copy any error codes/messages before exiting the test.
Well, I ran the hardware test (the extended version) and it is not showing anything.
Today I ran consecutive episodes of a tv show and by about hour 4 the 'stains' were worse (in the am you could barely see them) so it definately seems heat related. I went to a nearby authorized apple repair shop and the young kid there was not much help-apple really was not either (out of warranty) I guess I just have to stick with the local store and have them take it in and look at it.
I have always thought this thing ran hot, probably the first week I got it I called and asked them about it and they poo pood me!
There were quite a few (possibly heat related) screen discoloration / graphics issues threads here about two years ago or so, but that is now too late for you. It's too bad you weren't persistent when you first got it - I would not have found it acceptable.
In any case, tell the shop exactly when the symptoms show up so they can reproduce them.
I've been having "staining" on my monitor... darker "splotches" on my dark gray desktop.
Normally I put the machine to "sleep" at night via apple menu.
I read somewhere on the board that it is caused by some condensation that can build up from sleep. I was told to set "put computer to sleep" to NEVER and to use a screen saver set for 15 minutes and display-sleep for 30. The thread said that an Apple tech told the person to keep a constant temp in the iMac... either hot (running) or cold (off). He said that sleep mode is "lukewarm" and can cause issues with screen colors. Sounds reasonable to me, I suppose.
Last night I shut down all night and this morning I booted up and there was no discoloration. I went for a walk and screen saver came on and when I got back all is well. I'll report back. Maybe this is just a simple temp issue. Oh.. I'm in N. CA and it has been very cold and damp at night the past few weeks and house goes down to low 50s at night. I'm not sure that has anything to do with it.
