GE Free Standing Range Oven JB900SOK3SS Control Panel Blank Surface Burners work

[rgr]

Control Board WB27T10502 GE Model No: 191D3159P134; ERC3B-2K1
Touch Panel has no lights or buzzer, unresponsive. I cleaned the touchpad ribbon to no avail. I have experience troubleshooting PC motherboards down to the component level, but not with appliances. I think I need a schematic/wiring diagram to trace voltages, continuity, etc. The unit has been barely used, unfortunately the touch pad is integral with the front panel/fascia.

Any quick tips, advice or help will be greatly appreciated, thank you.
