RCA TV I have a RCA HDTV. For the past month or so it has been turning off by itself, sometimes even turning on itself too. This past week it would only stay on ten minutes tops and now it will not even stay on a minute. The power light comes on but no picture and within a minute it shuts off. What's going on?

Sir try to check the bulb if not damage sometimes it has a factory defect. Sir let me know if the bulb is ok. Good day and best regards.

Your convergence has failed and needs to be repaired. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

A problem in the deflection board. Could be a Cap. Resoldering the deflection board may take care of the problem. You need to call a TV man to do this kind of work.

Best of luck

Hi,
If it is Sony KDF-42WE655 model then it sounds TV needs lamp.
Have you replaced its lamp since 2006?
And please check when TV gets off itself, does its standby red light blinks? if yes, how many times it blinks? This is an error code.
Let me know to find out any possible solution.
Thanks.

RCA hdtv has a crackle then smell like something burning and then shuts off. What could the problem be

Color Wheel.

the best thing you can do is take it to a shop and have it repaired as the problem has gotten worse..

Just had mine repaired yesterday.

They relaced a TD4611 voltage regulator and a C2200uf 50v part.

Total including service call $188.00 in Western Canada.

I would turn the circuit board over and check for clod solder joints and cracked solder, you will have to look close, my other sugestion would be to get a can of freeze and spay the different IC's and see if it stays on longer.

The fault is most likely in the sync amp section, or in the video detector section, or the area where the sync extraction is done. It is very common that some of the electrolytic capacitors in the mentioned areas become worn down with age.

An experienced TV service tech should be able to troubleshoot the sync areas, locate the faults, and replace the defective parts.
