T.V. won't turn on

RCA T.V. Model no. P46734B4
The T.V. was working fine. Turned it off and later tried to turn it back on. The on light blinks on and off 3 times then nothing. It's off. You can hear it click each time the light blinks. But not picture and no sound. Can you help?
I would appreciate any advice I can get. I figure that the light blinking on and off 3 times means something.

This is a classic symptom of high voltage shutdown. There is probably a bad flyback [high voltage transformer]. The problem is one for the techs. Replacement usually involves also replacing several H/V components as well. The TV tries to come on, energizing the H/V circuits, then, the protection circuit detects too much current and goes into "protective shutdown" and then tries again. After a few tries, it stops trying. The protective circuit us there to keep from blowing breaker or causing a fire.

If it's an expensive set, take it in to the shop, otherwise go shopping for a new one. This repair can run anywhere from $100 - 400.

TV wont turn on, makes buzzing noise and shuts off


I have two RCA HD52W59 TV's. I have had one for 3 years and one 4 years. The one I have had for 4 years is giving me the problem. Last week the tv turned off while watching it. It wouldnt come right back on. 10 minutes later we tried and it worked fine. the other night the kids were watching and it turned off and smelled like something burning. I tried turning it right back on and got no power at all. I tried to turn it on two days later and it made a buzzing noise and the green light went out. Never did get a picture, no powering up on the screen. Any ideas? Don't want to spend alot of money. Really loved the TV hope it isnt junk now. Better yet I hope the same thing doesnt happen to the other one I have.

Need solution


Hi,

Appreciate the direct "Ask Me".

Your concern with an RCA D52W26 is when you attempt to turn it on, it powers up as indicated by the LED lights but they then power OFF a few seconds later? or it powers on then you get to see bright line(s) left to right, then the TV powers OFF? or it powers on but only bklinking LED lights? If yes on the last any sequence to the flashing/blinking?

Hope that this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Please post the model number of your RCA as usually its a bad flyback and start up capacitor when you get a 3 blink error code . But I can help you better if I have the model number of your set.

Not turning on again


try cleaning The air filter in your set. It may be a thermal problem due to a clogged air filter.

TV auto shut off-power indicator light blinking-won't turn back on


You could have gotten an electrical surge that put your set into a shutdown condition and unplugging the set and letting the Microprocessor reset will fix this problem if it dosent blow out the main power regulator as you still or might I say have a regulator IC problem. IF THIS PROBLEM HAPPENS AGAIN MORE THEN A FEW TIMES WITHIN A SMALL TIME FRAME I WOULD HAVE THE SET LOOKED AT BEFORE THE REGULAOR BLOWS SOMETHING OUT!!!!
