From Service Manual 368869, p.41:

1.Check whether there is condensation on the Main PBA connectors (CN9/CN10 for DMR77, CN10 for DMR57, or CN801/CN803 for DMR78/77 new PBA, CN801 for DMR57 new PBA).

2.Measure control board supply voltage at the test points. Expected: 12 VDC and 5 VDC; a drop below 4.75 VDC on the logic rail points to a failed onboard regulator.

3.Inspect all connectors on the main control for corrosion, thermal stress, or backed-out pins. Reseat each connector with the power disconnected.
