Re: Keeps turning off
This unit has a common problem with fans. If one of the cooling fans is intermittent the unit will turn off when the fan fails. A qualified tech with a service remote can get into the service menu and on this unit the is a menu line that shows pwr down failures.

Kindly do not keep attempting to turn it on, as you are likely to spoil some other boards/parts/components of the TV. Look for any loose contacts in power out let, RC jack, cable and socket. In order to ensure, it is not caused by the input device, connect a DVD player and see. Switch off TV, switch off power, remove plug and wait for 48 hours and retry. If problem persists, I suggest it is better to refer it to a qualified service technician, since the back cover has to be opened for investigation/rectification.
I would start by pulling the batteries from the remote control. Manually turn the TV off and then back on, manually. If the issue resolves, replace the remote.
If the issue continues; you will need to find a local TV Repair Shop and have the Tuner Board replaced.
Check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis. If you wish to get some details; check the site linked here. Pull up older posts. Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts. http://electronicshelponline.blogspot.com/ The most probable cause is with its audio output IC itself; overheats.
I Have the same problem, LG 32" , LC2D a couple of work arounds that work are
1) - never unplug the mains plug
2) - i noticed it does this when the clock time is --:-- , i find that switching to digital tv can stop this,
however these are only tempory fixes and the problem re surfices, as i have found out after having no problem for 12 months, i have accidently unplugged the mains, and now the tc keep turning itself off,
Its the BULB people! You need to change it every 3 to 5 years! I have had my sony 55" for 6 years... I had Best Buy come out 3 years ago, changed the bulb... it worked fine. Just started flasshing and shut its self off and back on again. Time for another bulb.
