Hi
have an issue with a Graphics card, am new to repairing graphics cards so will explain my findings as best I can
12v 3.3v 5v 1.8 & plex all present for about 15 seconds
then no plex, no voltage on the VRM no voltage to VRam 12v 3.3v & 5v remain present
I suspect faulty VRam as the resistance from what I believe to be the ram coils see picture with green box, is only 6.7ohms, shouldn't this be a higher resistance ?
2 of the VRam chips have black spots in the corners am not sure if this from the factory have enclosed a picture of this
any help would be appreciated
Thanks in advance
