Hi there,
Odd problem with 27" iMac mid 2010. The customer chipped it in, screen turns black although Mac is still running, no wake up possible. ASD says: Replace the LED driver board.
Did so, everything is fine. The customer being on holiday, I had the opportunity to 'torture' the thing nonstop for a week: all programs running + youtube videos -> not a single failure.
After a week of usage, the poor Sir brings it back -> 'Same as it ever was ' ( Talking Heads )
Now ASD says: Video controller failure ( Test #3 - #12 open GL )
So whats this now? Logic board or video card? Repairable or scrapyard?
Thanx for helpful comments.
Kind regards from Krautland
