I have an LG 47LB5D LCD Tv that shuts off after approximately 30 minutes running time. It will cycle back on after a few minutes, so I assumed it was the power control board; replaced it but Tv still shuts down. It does seem to stay on longer, sometimes up to 2 hours without shutting down. When it shuts off, you can hear a click as if a switch threw. This started after a lightening storm but not sure if we had a strike.

I have an early ps3 with 4 usb slots, my problem is that when i power on by the front switch, it shuts off, i can repeat turning it back on and each time it stays on just a bit longer each time, i may do this 10 times before it comes on and stays on, and i am able to play any game with no problem until i shut it down, this only occurs when it has cooled down for a couple of hours.... any ideas or thoughts for fixing this problem?

My Toshiba powers off every few mins and will not turn back on until i unplug the tv and plug it back in. Will only stay on for another few mins.

Removed front panel and placed a fan there in hopes the the heat syncs are now being over worked. Still shuts down every two mins.

I have a 32" flat screen tv that will stay on for somewhere around maybe 15 minutes. It shuts itself off. It won't turn back on for anywhere between 30min to 1hr. Unplugging it and replugging it in doesn't seem to make a difference. There are no flashing code lights when it shuts off. I have opened the back and all of the capacitors look good, none blown, bulged, etc. There is no burn marks on any of the boards. I can't see anything wrong with it... Of course I don't have

My tv, and also my mother in law's, which were both bought at the same time 6 years ago, started turning off by themselves. They won't turn back on immidiatly but if I wait a few minutes They will come back on. Not for long though, about 10 or 20 seconds or so. Seem's like the longer I leave the tv off the longer it will go without shutting down. Any suggestions? The TV'S are not at the same residence.

RGB to DVD player. Hdmi to dvi cable and occasionally a VGA cable. Has worked fine in the past with more connections.

Set will turn itself off, then on again, repeatedly and will eventually stay on after cycling various times. Did vacuum back of exterior, seemed to help for about a week. Also, seems to correct itself (not 100% sure), if you catch it while on and turn off then wait 5 min, seems to turn on and stay on.

The TV seems to take ages to turn on, the red on/off light flashes and then goes off completely and the screen stays blank. It then switches on again and after a few seconds/minutes will switch back off. Eventually it seems to warm up and stay on. On occasion it will take up to 10 minutes for the TV to warm up and switch on. Once on there is no problems. I have not tried fixing this as I feel it may well be a job for a qualified technician. Please advise if the TV is safe to use, and what's need

I have a Olevia 226T and it keeps randomly shutting off. I tired unplugging everything and letting it sit over night but that only fixed it for a day. If I shut it off all day and turn it on at night it will work for about 40 minutes before shutting off. When I turn it off then and turn it back on it will only stay for 10-20 minutes. I have had the tv for about 5 years and never had an issue before. Any help??
