Question about RCA HD52W56 52" Rear Projection HDTV

1 Answer

Tv won't turn on. power indicator light comes on then goes off after about three seconds, then retries twice more then locks out.

I,ve also tried holding the power button in the on position, and it flashes once [the indicator light] then flashes nine times then locks out. i'm assuming this is some kind of diagnostic code, but i can't find any blinking codes on line. any suggestions?

That is what these sets will try to do if the power supply detects a short. The set will try three times to come on then shut down again till you pull the plug or press the power again. It is not really a diagnostic code. Most likly your problem is the horizontal output transistor and or the flyback transformer. Very common problem for this set. good Luck Please do not forget to rate this thread.

CODEFOR PENSONIC TV


Hold down the TV power and power buttons together until the indicator blink twice. Key in 9-9-1. The indicator should blink twice again. Press the TV power BUTTON, Aim the remote at the decoder and press the CH+ channel up button and wait for three seconds again. Repeat the steps until the TV turns off. You`re basically iterating through the TV codes in the remote`s database. Press the OK button once you find the correct code.

Also try codes 0067, or 3778, or 863 for Pensonic. Some people have reported that these codes worked for them. Good luck!

Toshiba 32AV502R won't turn on even though green light goes on


Try changing the input device to something you are sure works. Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.

3 blinks indicates lamp door is not on or has not been reinstalled properly. This also could mean the lamp door switch has failed itself. Try removing the lamp door and putting back on, if that doesnt correct the problem then I recommend having the switch replaced.

The tv is going into protection shutdown. It will try to power up three times, but each time it tries, the microprocessor recognizes an overvoltage, or overcurrent draw, and after three attempts it will place the unit into protection shutdown. There can be many causes of this, but the most likely one is that there is a short circuit in the high voltage circuits. You probably have a shorted flyback and associated components.
