Hi
I have some a1280 820 2915 boards no one gives image at all... but they turns on and chimes.
It is very likely to be GPU issue so wanted to follow jumper gmux converting to uma way...
My question would be: is this posible? since they dont give video ...no backlight...no gray or white screen no logo...
I mean chime is heard ...fan spins .. mac is on but no image...
Is uma conversion posible only when you have primitive video? Or can be the case when you do not have video at all?
Thanks in advance.
