Question about LG 42LC2D 42 in. LCD HDTV

1 Answer

LG LC2D Recently my (about five years old) LG 42LC2D LCD television has been blacking out for varied amounts of time. Sometimes no picture is visible for minutes, other times, seconds. This occurs when watching regular cable, not HD, and when watching DVDs, and playing PS3. The sound continues to be transmitted perfectly, so I can hear the audio crystal clear, just no picture. After some time the picture will return, but it is getting increasingly worse - not too unbearable, but I know it will definitely get there. Currently I only have my PS3 hooked up to it, HDMI, etc. I thought maybe the console could be aggravating the problem. I hope I can get some feedback as to potential issues, I realize a definitive answer is near to impossible without a technician actually opening the thing up and seeing the mechanics, etc. Any advice would be appreciated. Potential costs (in whichever area you're in) would be helpful as well. Cheers, from Vancouver

Bravo, I think this is the best stated question I have seen on FixYa in the four years I have been here.

My opinion would be that you are having a power supply issue, without testing the voltage to the backlight I would guess you have a failing capacitor on the PS board.

A good place to start is:
When the picture is blacked out
Shine a bright light(flashlight) on the screen
Look very close for an image
If you can see the picture your backlight is not functioning.

Get back with me and will will get this fixed for cheap

LG 42LC2D screen periodically blacks out, sound still plays

It is possible the salt air may have corroded a marginal connection ont he 24 volt supply. You can either simply buy a power supply board from any of several online vendors, and swap the board yourself, or you can try reflowing the solder on all of the connections on the Power supply board. Replace all the electrolytic capacitors in the 24 volt supply portion of the set while there.

It would not hurt to check the inverter board for bad solder connections as well, excessive leakage across transistor terminals in the oscillators, and potentially stressed electrolytic capacitors that may or may not show visible signs of stress.

Hello, having aproblem with my LG LC2D .TV.only had it 2 days.Problem is turn t.v on and picture goes off can still here sound [time varies sometimes it will stay on for 2hrs sometimes only mins.]not very...

There is nothing you could have done other than physically breaking it (that would be obvious). There is a problem inside the set. Return it for an exchange. These things happen although rarely. Don't waste any time on this, just get it exchanged.
