Re: toshiba television

Is it a Toshiba or RCA? What's the model number?? When it "stays on..." do you get a picture and audio okay??? If you continue turning it back on does the lapse in time continue to get longer????

Toshiba 27af45 repeatedly turns itself off. Sometimes (usually) every few minutes, other times will stay on for hours. Works perfectly otherwise.

The fact that the television stays on for hours and other times turns in five minutes shows that your problem is intermitent .A defective component in the power supply is probaly causing the B plus voltage to go up.The TV can also have a dry joint which looks more likley i am curtain if you gave the TV a firm tap to the side when it come off it would come on back. Try it .

Is the tv getting too hot and shutting off? Vacuuming will help get the dust out of the fan but inside the actual tv there may still be dust blocking cooling.

Philips/Magnavox TV, model MS3250C321 shuts off randomly.

TV shutting off automatically means its a problem with the Lamp. Contact Pioneer or any local tech shop or Best buy and get the same replaced.
Turning off after specific time : Go to the timer option and disable the Automatically Switch off option. This will resolve the issue. Please let me know if it worked. If you need the user manual or instruction manula please click on the link below Hope this will be of help to you.

You most likely have some broken solder connections either in the low voltage area or in the horizontal section of the tv, board has to be removed and re-soldered, hope this helps
