Question about Televison & Video
For sure you are getting a higher voltage on to the section where the limit is 200 volts. So the Switch mode is irregular and not regulating the power output. Possible failure of the invertor oscillator IC., the power diode. in series.-possible AC factors coming in.
It is easier to trace back logically into the section of the positive voltage that the capacitor receives to identify.
When powering use a variable power supply to check before the full voltage is applied.
