    tv stays on for seconds and turns-off ---- what is going on

  • Anonymous Aug 29, 2008

    Same problem - turns on for about 3 seconds and then shuts off. Took it to a tv repair shop - they told me the entire panel had to be replaced - $400. No thanks - the tv only cost $275. Should i try another shop? Spent $50 on the first one.

I had a similar problem and I believe the problem is with the high voltage circuit and ccfl transformers. If you know electronics you may be able to find the chips that provide the power input to the CCFL transformer (I had two transformers and 4 FET's). You will also need a micro soldering station and excellent soldering skills to replace the flat packs (SMT). Hope this helps.

Older-model Toshiba TV shuts off by itself


There is a large sand filled resistor on the main board close to where the power cord attaches that cracks. This will stop power until it cools enough to make the connection then heats up rapidly to open it again. It may be worth the trouble if you're handy with a soldering gun and can get the back off the TV. If not then I'd consider getting a flat screen.

Set is 7 years old - it turns off intermintently


Ours used to do that - and then we moved it to another state with us. Since the move it doesn't shut itself off anymore. I suspect that the problem was dirt and dust inside which got knocked loose in the move and the shutdown was due to thermal limits being exceeded. You may want to try vacuuming or blowing out the dust inside if you feel comfortable opening up the unit.
