MY LG 42" LCD TV


Tries tv unplug,replug it back like about an hour later for the tv resetting itself back to the factory setting.Tries again,tv should be working.If still getting no power at all than the tv Tuner board is dead,because pictures freezing and dies completely is the causes so it is not power supply board problems.The tv Tuner signal board is the causes,that the board where the incomming broadcasting signal cable plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish tv Tuner signal board for the replacement.

Turns on and off by itself


If this happens on all inputs and you have disconnected the power and reconnected it and that didnt fix it.

Sounds like a logic board issue problem is LG only warrenties tvs for 1 - 2 yrs.

My 42 inch LG plasma turns on and off repeatedly when I try to turn it on. happened a few times before when tv was working fine, now it wont turn on at all. I have to unplug tv to get it to stop turning on...


Theres a short between the start-up processor signal on the interface board and power supply. It keeps sending the same start-byte over and over again to the power board. This could also be a DC high voltage shutdown on the power board its self. Now the tv is in protection mode to prevent further damage. Get it serviced at your local repair center. If its under warranty take it back.

42 in LG LCD TV turns off by itself


Found that TV started switching off by itself. Would try to come on..green light blinked for 2-3 seconds, tv came on (with picture and sound) for 1 or 2 seconds and then it would turn itself off. Found that the issue is with one channel only. If you are facing this issue....try quickly changing the channel the moment it comes on. You can do it either with remote or with the TV buttons directly. also in the same logic, if this is still happening, try changing the source to another (rgb-pc, av1, av2 etc). Basically change it from whatever input it is on currently, if changing the channels does not work. My symptom was that the tv made a loud 'TIK' 'TAK' sound which is louder than normal.
