Hi, I have tested the voltages of the memory on the RAM board, Voltages are around 3.1-3.2V when the computer is powered off and around 5V when the computer is on. I have taken out the Extra memory it have with no luck. The system has no extra rom in it. The flex cable is align in the slot. But still a black screen. However the contrast knob still doesn’t function but you can hear interference when the contrast knob is turned but no effect on the screen. I try the beep test, that still doesn’t work so the system must be stuck. I have re-seated the ROMS but nothing changed. You can hear the system reset when you push the reset button or turn off or on the system from the speaker clicking. Also some times the board clicks randomly like a 5v relay is going off and on.
Any ideas, I am sort stuck? Thanks, Ethan
