Question about LG Televison & Video

Open Question

My 32LD460 turns itself off after 5-8 minutes. I just turn it back on and it doesn't happen again. It isn't the sleep timer, and there is an ariel signal. When it first turns on, it starts up quickly, after this self shutdown, it takes longer. Puzzling.

SOURCE: screen keeps going blank

SOUNDS LIKE YOU HAVE A BAD LCD PANEL. THE LAMP DETECTION CIRCUIT IS SEEING A BAD LAMP OR DRIVE TRANSFORMER AND IS SENDING A SIGNAL TO SHUT THE PANEL OFF. NOT WORTH MESSING WITH PANEL WOULD HAVE TO BE REPLACED

This sounds like a protection system cutting in. This happens if there is a major fault and continual use would lead to a fire risk.

SOURCE: 8 month old Symphonic 20 inch lcd tv turns off itself every 3-5 seconds

I have the same problem with mine and its 5 years old I took it apart cause i blew a fuse. I fixed the fuse and got this problem. So my fix was take the tv out back and put 43 7.61mm round in it. The tv is really messed up now but I feel a lot better and know not to buy symphonic any more.

My Sharp LE820 Aquos LED TV recently auto turn itself off, when I turn it back on, a few good 10 minutes or so later it automatic turn itself off again.


Please check that the sleep timer did not somehow get set. If it's not the sleep timer, check if the panel stays ON longer after it's been off for awhile to cool down. Possibly a heat problem with the power supply or main board.

LG 47LD450 comes on, then unexpectedly shuts itself off. No standby power indicator, no nothing. It turns itself back on after 2-3 minutes. This isn't a sleep timer issue. What else could it be?


Well I'm not a T.v. expert but sounds similar to over heating problems. Is the ventilation covered or filled with dust? Try unplugging it and take an air can to the vents to blow out any dust it's collected over the years.

My radio powers off every few minutes. Needs to be turned back on by the on-off switch. How can I stop it from turning off automaticly?


When you press the Power/Sleep button the radio turns on and displays a number 90, or some other numbers. This is the play time that the radio will stay on then turns itself off. It could be that yours is configured with a sleep timer set to 01 minute, 10 or 15. You need to set the timer for a longer period. Thus we turn it on by pressing the Power/Sleep button, read the timer length then press again. Keep making short presses: The timer will cycle through all preset sleep timer durations. Select the length you want.

Sanyo television doesn't turn off either by using the remote or by turning it off at the tv.All other fuctions work using the remote or directly on the set.Even using the sleep timer doesn't turn...


Unplug the set and hold the power button for 30 seconds. Plug it back in and see if that fixes it. If it doesn't then it sounds like there is a problem on the board underneath the power button. Something isn't allowing the circuit to be cut.

Tv switches off after 5 mins


There might be three or more reasons for this:
1) The sleep timer may be on causing the TV to turn off after a preset time.
2) If sleep timer is on and no signal from the remote is received for a preset time (Samsung: 15 minutes) the tv will turn itself off.
3) The TV may have been turned on automaticaly with "On Timer". If so, and no signal is received for a preset time (Samsung: 3 hours) the tv will turn itself off.
4) A fan is not working or a vent is blocked causing the TV to overheat and turn off.
For 1) thru 3), go to the "setup" menu and make sure "sleep timer" and "On Timer" are turned off.

RCA HDTV model#HD52W59. When I turn the power on it stays on for a few seconds and then goes off by itself.


TV turns off unexpectedly
• Sleep timer may have been activated.
• Electronic protection circuit may have been activated because of a power surge. Wait 30 seconds and then turn on again. If this
happens frequently, the voltage in your house may be abnormally high or low.
• Unplug the TV. Wait ten minutes. Then, plug the TV in again.
