TV turns off by itself after 35 seconds of being on. Indicator light flashes red endlessly.


The TV is going into protection mode. Could be a problem with moisture. Can you try warming up the rear with a hair drier? Ensure that you do not apply too much heat to avoid damage to plastic parts. If you can remove the back cover (after unplugging the power outlet and switching off the TV), try doing in on the entire PCB, if you suspect moisture is the problem. Please do not touch anything in the board by bare hand as there would be high voltage charge in capacitors even after switch off. If it does not work, this might need attention of a qualified service technician

My 42LD450 won't stay on! It turns on for a few seconds and works fine, then the screen flashes then comes back on, then flashes again after a couple seconds, then turns off. Rinse and repeat. Tried...


I hope that you can use the warrantee.

Otherwize, it must be possible to repair it with a fried comfortable with electronic because the problem is not permanent. This kind of problem is usually an old capacitor or a bad connection (soldering).
It would be important to check if changing the ambiant temperature fixes the problem. (I.E. move it to the seller for 2h and try..)

Lg 42ld450 is not turning on. It keeps flashing "red" in what appears to be the power saving mode. Any ideas??


The power board or power supply could be the likely cause of the problem. Have that checked out.

LG TV Turns itself off


Sounds like it could be a poor connection in the power plug or a ' dry joint ' on the power board, if it's the latter, it will respond to light thumping at the side of the tv. If that's the case it needs resoldering by a technician..
good luck !
