I think you might have a bad solder joint in the power supply circuit or a bad solder connection in the horizontal drive circuit. I've found a few RCA's that had a poor connection on a little inductor coil in the base circuit of the horizontal output transistor. A drop of solder cured this problem. Stargazer

I have a 50" philips magnavox tv that changes channels on it own and turns itself on frequently. What is causing this issue?


Do you live with someone who likes practical jokes; even silly ones?

There are a number of companies that make remotes that can mess with someones TV or other remote devices.
I have a watch, as a gag, that will self program its remote to operate any TV capable of this feature. With this watch, I can change channels, power status and even reset the TV to factory default state.
Next time this happens, look behind you.

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

My mitsubishi tv model ws55908 will just turn itself off after I have been watching it. It could be as soon as 1 or two hours or 4. it does not happen all the time I can go a month without it happening...


This TV has a self diagnosis feature. When the set fails, push "menu" and "input": buttons at the same time and hold them in for more than 5 seconds. Watch the front panel light. It will blink two numbers five times. Get back to me with the numbers.

When it shuts don, the standby light should be blinking a repeated pattern. PLease update this with the count of blinks. That will indicate the circuit that caused the shutdown.

If it is not a cold solder on the CRT board at the end of the tube (inside)...... then the CRT (tube) is bad. The CRT costs more than the set new.

TV turning off


INtermitant problems as the are called usally mean bad solder connections...the joints between electronic components. this set when it has a problem shuts down. This is safty cuircits. It could be a connector. when the set shuts down. it locks out for a period of time.. DO you have to uplug it to reset it? IS there any sounds. Without know more i would guess its high voltage.

Turning on


I have had this happen too. You need to unplug the unit so that it resets itself. After you re-plug it in you need to set the time. If you just reset it without setting the time it will happen again. This has happened to me a few times. Good luck!
