This TV probably needs the convergence amp IC's replaced. When they go bad the TV will not turn on.Call a good TV Tech and tell him you want the IC's upgraded to STK 392-150 instead of the original STK 392-120 and check all resistors in the circuit for proper value. They could be burned or open.

I have a 50 inch LG plasma tv that is less than 2 years old. It use to turn on by itself throughout the night, and now it's completely not working???


Hi there
Try doing a system reset on the TV, by unplugging everything from it, then wait 3 minutes and plug the power lead in only. If it works, then plug everything back in one by one. If the problem persists it may be that the software has been corrupted in an update process, which can be performed at night via the aerial signal (this may be why it was turning on at night). In which case contact the TV manufacturer.
Hope this helps

We were watching TV and the TV just turned itself off. We try turning it back on and we have a black screen for 10 seconds and then the TV turns itself off again. Called Sanyo and they said to unplug it...


Yes,unplug,replug the tv an hour later.The tv should reset itself back to factory setting and work.Not,than the tv power supply board have problems.That the board,where the power a/c coard plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

Picture goes off


A temporary solution is to unplug the TV for a few minutes, remove static from the glass with your hand. It is important to unplug rather than turn off. If you have a degauss button you can also press that before unplugging. Wait several minutes or an hour. Then plug it back in. If you have Picture in Picture it may be an issue with that and to permanently solve may need a repair person. The unplugging may get you by for a few days at a time. That's at least better than an hour.

Samsung hp-t4254 plasma


Hi Rickpo:
After installing the $11 kit and the additional $13 kit recommended by (http://preher-tv.blogspot.com/2010/01/samsung-hpt4254-no-power-repaired.html) mostly surface mount diodes (also available on Ebay), the Samsung HP-T4254 came back on, but would only play for 4 minutes. I found DX801 flowing both directions, replaced it with a diode from Fry's. Works great, $26 total repair costs :-)

Power light flashing/ no picture


I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.
