I have new measurements, now that my meter is properly set to DC voltage. On startup, VS voltage briefly peaks at 211 VDC, then drops, at first sharply and then slower and slower until finally settling at 11 VDC after about a minute. VA voltage peaks at 57 VDC at startup, then quickly falls off to zero.

See the attached image for the power supply board part numbers - there are several BN44 numbers.
