Question about RCA P52937 52" Rear Projection Television
When I turn on the TV, the power will turn off and on. It used to do it every now and then, but now it does every time i turn the TV on. Please help! Thanks!
The power supply section is having trouble.
Common possibilities are:
- Convergences amps are failing, overloading the supply
- High-voltage section (flyback transformer) is failing
(happens sooner or later, about 8 years typical))
- One of a hundred of electrolytic capacitors has failed short overloading the supply. They dry out with age, are cheap to replace, but hard to find which one it is.
- Or any of many other possibilities.
In short, you need a experianced tech to troubleshoot this.
