Question about LG 42LC2D 42 in. LCD HDTV

1 Answer

TV won't turn on after being off for an hour or so. LG47 " LCD

My TV have developed this same issue repeated inquiry's to LG yield the same result " we can recommend a repair facility." This is gonna cost ya. From all the other post I have read about this issue it looks like a power control board issue with bad cap's. This problem has hit the computer industry also. There is/was a manufacture in china making these crappy cap's and sold to everyone. ( must have been cheap ) gateway dell IBM hp bought them for their system board and a year or so they leaked. this must be the same issue. Know I have to take this unit apart and try to replace these cap's ohh boy looks like a challenge will post how i make out when i get the courage to do it.

Replacing capacitors is a guessing game. 60% of the problems are caps, but it could be a bad diode or a mini-transformer. For a do-it-yourself, best to have the best research material available for the TV to get down to the real problem. A Service Manual for the TV will have the diagrams, schematics, test points, and part number lists.
If your TV model is 42LC2D, here's a link to get you one:

LG LCD TV volume/sensor problems


it could be 2 issues: faulty remotes or stuck buttons on tv's keyboard. Where did you get 2 remotes? cable or directtv boxes? those are universal and must be programed to work with tvs. or, do you have 2 identical LG remotes in your household? either way, if you have kids on premises and lot of drinks carried around, remotes could be contaminated with fluids inside and malfunctioned. You must become a CSI and figure it out!
Good luck and let me know the results.

There is a green line from top to bottom on my lcd tv LG47''


Most likely it is a LCD panel failure.
If it is out of warranty I would call LG to see if they could help with the repair cost. Their Customer Service Phone Number is 1800--243-0000.
If it is under warranty, they could help you find a Authorized Service Facility near you to repair it.
I hope this helps,

power supply is developing sustain issues and will eventually shut down completely. get it serviced now before it becomes a real issue and too expensive to repair.The way it is now the repair cost should be acceptable.......
