8590A ADC 2V Fail

Hi

My 8590A now displays ADC-2V Fail and ADC-GND Fail. I see inside that the 15V led is off and the fan doesn't spin (tested separate and it is fine). The power supply is fine when disconnected, and removing the boards one by one doesn't seem to fix the problem. I can't find the service manual to see what is connected to 15V. Any suggestions or where I can find the service manual and/or wchematics.

Thank you, Kevin
