Looking at your picture in post #149, the Rifa capacitor C30 is connected from one side of the mains connector to S3, which is correct. However on the same pin of the mains connector is a reddish/brownish wire which appears to go to V4, Unless a spare pin on V4 is being used as a termination point this is incorrect. The wire should in fact go to the voltage selector.

The other side of the mains connector is connected directly to S3 which is correct.

I would suggest reverse engineering this part of the circuit.
