It's normally a power failure/surge on the main board. Most common with LG tv's of this type. Samsung tv's of this type don't actually turn off, they only go on standby, which is why you can turn the Blue Eye off in the menu. One solution to try (if you haven't already), is to disconnect it from the mains (this is also the only way of actually turning the tv off), leave it for 24 hours, and try again.

Not really that tough. Sounds as though the backlight is shutting down, either from a power supply failure, or a failure of the backlight circuit itself. You can verify this by holding a flashlight to the screen in the area where the menu usually appears to see if it displayed on the LCD panel with no backlight. If you can faintly see the menu displayed, your backlight has shut down and the most likely cause is the backlight inverter board, followed by the power supply and the backlights themselves which are part of the LCD panel. If you found this information answered your questions, please be sure to rate it. Thanks!

When I turn on my Sony TV, ti stays on about 30 seconds then shuts off, What do you think is wrong?


Do a Power Reset.
1. Turn off TV.
2. Unplug the power cord of the TV from the electrical outlet.
3. Let the TV remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet. (If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.)
5. Turn on the TV.
If issue persists after doing the steps, reset the TV to factory default settings.
1. Turn on the TV.
2. Using the supplied remote, press and hold the UP arrow button.
3. While holding the UP arrow button press the POWER button on the TV itself.
4. When the TV goes off, release the POWER and UP arrow button.
5. The TV will turn on by itself and the initial setup screen will be displayed. Just follow the on-screen prompts to finish the setup.

The screen will turn on, but after 2 seconds the screen goes black, the power button stays lit, and sound remains. What could this be?


it could be a bad CCFL lamp, inverter, power supply 24vdc output, or a main board problem. The set will need to be properly diagnosed.

Did you check the service manual troubleshooting guide yet. You can try disconnecting the power to the inverter board and see if it will stay on and have sound.

I have the same model and the same problem... I am told the power display board is is the issue and may need to replacing. New board costs around $80,or a bad capacitor depending on your paitence.

Screen goes black but still sound


This is inverter or backlighting problem. Can you try switching it on and off quickly for a couple of times and tell me if these '2 seconds' get any longer'. If picture stays longer and longer before shutting down, one lamp needs replaced-if not, please replace inverter board

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.

TV turns on, then immediately off again


hi nel2874

so, you have a television that turns off immediately after you turn it on.
It sound like your power supply on the unit is out. Because I don't know the value of your unit I cannot comment on replacing the unit. But I would recommend that you use our website to find a Flat Panel TV Repairman near you. You may want to call to get an estimate on replacing the power supply before considering replacing the unit.

T.v. will not stay on


Power on your TV and press the INPUT button on the side of the TV repeatedly and rapidly until you can change it to a different input, such as AV.

If this does not work. Try this: With the TV off, press and hold the input button on the side of the TV for about 5 seconds. The TV should power on and the input list will appear. Let me know if either of these work.
