Display not working Properly please help???

Question

Hey all I have read thru about 25 pages of different posts relating to the video screen problem, and none see to be exactly like mine. I have 1st genereation IMAC G5, that had the orginally logic board problem where screen wouldnt come on at all, i got it fixed once under apple care warranty, then i had another problem where system kept crashing causing automatic restart which apple store genuis bar said was also logic board, this time i was out of applecare coverage but, i got ot covered thru the extension program that just ended in dec '08. Last week when i got home my screen was off, i restarted by holding pwer button down, then i got partial screen( only dock bar items, prgrams, & etc where showing, no desktop files), so i restarted again and got this strange pixeliate screen after loading(see image: http://i152.photobucket.com/albums/s183/nofate21/Picture001.jpg), so i rrestarted know during loading process I get normal apple logo, but with horizontal pink lines running thru screen at variables( see image:http://s152.photobucket.com/albums/s183/nofate21/?action=view&current=Picture003 .jpg & also http://s152.photobucket.com/albums/s183/nofate21/?action=view&current=Picture003 .jpg). Now it varies when i restart CPU, sometimes I get completely black screens, sometimes i get blue screen with nothing, and the last couple of times I get a black scrren with a mouse cursor that moves normally. i have also tried restarting while hook-up to external display(my lcd TV) and I get same image (although minus the intermittent/variable horizontal pink lines), please help with any suggestion or even advice( such as trash it, try to fix with ordered parts, etc) Have appt with genuis bar, but already know the will say $800-1000 for new logic board or whatever

Answer 1

Are you saying you already got it fixed but the problem is reaccuring??
I am part of the unlucky ones who didnt't have applecare or the extended warranty. My iMac broke down 8 months ago. I no longer have any display. The strange thing was I left it at home because I went to uni, so there was a period of at least 10 months where it was not used. But still it failed within a few weeks of me getting back home. I was sucked in by their adverts making me believe they were a superior computer to any windows based. How wrong was I. It has now left me with a very bitter taste.
Any of you guys know if it still will work if I connect an external monitor?
