And after looking at the schematics in the service manual, there should be a B + voltage emerging from the DC-DC converter circuit. But it does not appear, so the damage lies in this circuit.

To ensure that only a DC-DC converter circuit for B + supply supply to I would be advised to provide a B + voltage from the outside, ie a stable adapter or power regulator.

And then I turn on the tv, blaaaa ,, it turns tv can light up perfectly, appear normal voice and picture.
