I had the same problem. Got it to stay on by unplugging the front button pc board while I researched the issue. It seems that the switches on said pc board begin to "leak resistance" and cause all kinds of problems like on/off, color maxes out, as well as other crazy stuff. After calling RCA and getting no help I decided to remove those seven micro-switches off of the board and, wouldn't you know! Everything is ok with the exception of not being able to controll the tv from the tv itself. Small sacrifice for a free fix. All tv functions work from the remote. Again, a small sacrifice for a free fix! Just be careful when poking around inside, high-voltage and stuff.

SOURCE: rca turns itself off and on and scans thru all the channels

I have an easier solution, First I want to thank those who posted the solution that the problem is on the small switch board mounted right behind the switches under the picture tube. I figured that might be where the problem was but it's better to to see it confirmed. I thought the problem was more complex like maybe an IC chip got zapped or something but there are none on that board. Only 6 switches, the infared sensor, 1 capacitor and some resistors. I am convinced that in my case at least the problem is caused by humidity. It happened last year constantly durring humid weather in the summer and only a couple of times over the winter when the air is dry and cooler. I did figure an easier way to disconnect all the switches without unsoldering. After you remove the board, flip it over to the solder side and see where the wires connect. You will see them labled GND - KEY - +5 v - LED and IR. The one you want is labled KEY. You will see on the other side this wire is second from the end . Just separate the wires a bit and cut it. That's it. Just be sure it is the one marked KEY. This wire goes thru a series of resistors and the switches and nothing else. Just cut that one wire and put a piece of tape over the cut ends and thats it. it's a lot easier then unsoldering all 6 switches. And if you do decide at some point later to replace the switches, it's easy to resolder the wires and tape it. I did it this way and my TV is working perfect. I was done in ten minutes. You can only control the TV with the remote but so what, thats all we use 95% of the time anyway. I hope this helped you.

TV loose power, then regain 20-30 times a minute

It's trying to speak to you... it wants you to repair it. It must be where the relay is that turns the tv on with the remote control. All aging electronics needs the electrolytic capacitors replaced. When they age they throw the voltage off and cause many other parts to blow up. Aging solder joints could be a factor too. look for parts that have been overheating. The circuit board may have parts desoldering themselves and or overheating the circuit traces.

My sony has started turning itself off after 20-30 minutes, each time you turn it back on it will turn itself off after a shorter and shorter run time. Leave it over night and it will start the next day...

It might be over heating. If there is a lot of dust
inside of the back of the T.V. you should take it outside and blow it out with an air compressor.

good luck

RCA TV, model number 32V550T. No picture but sound is fine.


this sometimes is quite simple to fix as it cud be a dry joint on the circuit board where the tube motor sits.

or it cud be the tube is on its way out, which wud be cheaper to buy a new tv rather than have it fixed

Tv was working fine...then shut itself off.

there is no reset button on any tvs that stop in 1980s when they no longer used tubes in chassis,s now the only tube is your picture tube. you probly have a shorted hori out put transistor.
