Re: toshiba pdp50x3 power supply issue
Vs is a little high, can be adjusted down. Are both Vs and Va dropping out or are they good?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Vs at 211V? Sounds like over-voltage check. Maybe it will do that with no sustain boards, hard to be sure.
OK, can you post a picture of the chassis layout? Clear and in focus please.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

It was OK before?
Check all connectors.
Check all output voltages from PSU - not just Vs/Va but also 3.4V, 6V, 12V etc.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Also check AC DET voltage.
If you put the old power supply in how does it behave?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
