Question about RCA 20F511T TV
TV has power To front set since LED light is on for stand by button but won't react to button on frony or remote?
The main power supply section is not working.
(standby supply is OK)
Common possibilities are:
- High-voltage section (flyback transformer) has failed
(happens sooner or later, about 8 years typical))
- CRT tube has failed overloading the supply
- Power surge has popped the power input circuit.
(Fuse, rectifier diodes, turn-on relay etc)
- 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.
