I would suggest to check for cold or crystalized solder joints first, overheating regulator, dry or bulging capacitors around the power supply and lastly you may want to check the backlight bulbs for intermittent condition.
Good Luck.

TV goes to green, sound stays on a few seconds then TV shuts off.


Sounds like you have a bad picture tube. More than likely the CRT could be shorted, which would cause the set to shut down.
My first advise would be to power up the set with an isolation transformer with the voltage about 60% approx. 72 Volts AC, and monitor what happens when you increase the voltage slowly.
If the set remains on at 60 -70 %, then when increased to 90 - 100% it shuts down, you have something drawing too much current ( which could be the CRT )

Olevia 332h comes on for a few minutes then turns off


I have the same problem with my Olevia 332h. The TV shuts off after 10 seconds. I decided to wedge a desk fan in between the wall and the back of the TV. It worked! The TV doesnt shut off anymore. This problem is obviously heat related. I hope this information helps you.

New TV 9 mos old, Won't stay on after power up? Remote or manual turn on, set keeps turning off after 1-2 second green on and brief screen flash.


I would try leaving the TV unplugged for 30mins so the TV can reset itself.
If that doesn't work, your TV should still be under warranty. I know 95% of come with a 1 year warranty.
The most common problem with Sylvania TVs made by FUNAI, the Backlight Inverter board fails to early in life. ( That's the part that powers the screen)
The Tv can't power up the screen and it turns off automatically. Basically called "Protection Mode" so it protects the other parts inside the TV.

Loewe Articos 55 RP


There is a software patch that increases the cut off temperature you may get this at Loewe Website. Quick fix is reverse one of the fans on the back of the set this gives a through flow of air rather than all fans blowing into the set.

Lcd tv shuts down by its self


All you need to do is remove the back cover, then remove the metal cover that covered the power supply. Watch tv w/o cover, it won't shut down again. Try it and post here if it works.
