Bad voltage sensor for GPU from Apple Diagnostics?
Had a problem with the video card, would show the Apple logo at bootup , but could not get to the login screen. Had this happen before so I replaced the video card. Now I get no backlight. I replaced the LCD driver board with a known working and even swapped screens from a known working. Still get a dark screen , text icons, etc. can only be seen with a flashlight. After a few frustrating days checking connections etc. I decided to run diagnostics and got an error code. I *think* it says voltage sensor VGOR for the GPU is not working (see attached image). Any suggestions on how to proceed. Did I get a bad graphics card from ebay?
Ist dies eine gute Frage?
