No video after SSD upgrade, 2 LEDs on, 3rd off
After the initial replacement, the system worked and I was able to use it as normal. A couple of days later, the screen went black while I was using it, and have not been able to get any picture since. I took it all back apart, and have broken it down to having the least possible things connected with no difference.
When plugged in, I get LED 1. After pressing power, LED 2 lights up. I never get LED 3. Fan spins up when powered on, eventually running at max.
I’ve tried new PSU, new CPU, and new logic board with no success. I’ve also tried combinations of all of the new and old parts together without any difference. I must be missing something. Is there a ‘reset’ or something that I might be missing?
