Panasonic TC-212T power problem

Senu · Guest

I have a Panasonic TC-212T Tv the problem is that I have a power problem, that the relay clicks but nothing happenes only the LED is light normally & when I measure the voltage on HOT it's reading fluctuating from 4- 91v ( changing frequently. I think I have some grounding problems on the relay or power to the replay problem because when i was measuring volatges on secondary & with -ve of meter on ground & if i touch the autocoupler with the +ve the Tv starts & work normally & the fluctuating voltages reads normally 91V ( the B+ ), so help me what can be the problem

the power supply is not with STR , it's with a power transistor (C4804 ) and the i have checked all the resistors on the power supply, they r all ok. so what can it be ? give me some ideas plz

If the pwr supply has 2 capacitors in range of 2.2mfd 350v change them, and also one for 250v 10mfd, or check them if you have a cap meter.
I am looking at a different model, so values may differ, if they do then check the electrolytic capacitors on power supply.
