My stove's burners, including igniters work fine, but the control panel is dark and unresponsive, so oven can't be turned on. Problem is probably due to too high a voltage (220) across plug due to a generator problem.

Trying to figure out what to replace. The control board and display panel seem not to be getting power (Vdd to ground is zero), so I assume problem is a power supply, but can't locate it. Should I see a voltage (5-12 volts) across these wires with the unit plugged in? Is there a schematic likely to be hidden somewhere, and if so, where? Thanks for any help.
