Thank you for the reply Johannes. I've just checked the reset line and all of the components within it test ok. I've also completed the reset adjustment per the service manual, but still cannot get Bank A and Program 1 to light up once I remove the 56k resistor from KLM-376. The D/A adjustment steps that follow work as they should, but once those are completed and the synth is powered off/on again the LEDs remain stuck on Programs 1 and 8.
I misspoke previously when asking if my RAM chip may be defective. I meant to ask if there could be a problem with the Main CPU, D8048C-345? Could this chip be causing the programs to lock?
