Hi All,
Quite a few names on here i already recognise from AR & CM forums.
Anyway, I have a slightly different issue with this iMac 27" 2011. It came in with the usual GPU issue. This is no problem, as we ordered a NEW GPU card from Apple.
This all went fine, card replaced imac working fine, no issues at all, passed VST, AST ASD etc etc.
Next day just before calling customer, we tried it again. NO IMAGE/BACKLIGHT this time.
On further inspection, LED 3 is not illuminated. I assume we have been shipped a duff card from Apple. Not the first time, but quite rare.
We try 2 more new cards, and none of these work. All these cards are fine, so it must be a logic board issue.
Other than the logic board supplying PP5V_S0, PP3V3_S0 & PP12V_S0, what else should i be looking out for ?
Thanks
