Question about LG 37LC7D 37 in. LCD HDTV

LGE LCD Remote Control no longer works

We unplugged our LGE 42" LCD TV (and AV equipment) during construction for several weeks. When we plugged everything back in, the remotes worked for everything else, but not the TV.

The Cox remote works for the cable, but does not operate the TV. The TV remote does not operate the TV. The buttons on the TV DO operate the TV, so I know the functions still work.

What could be causing the problem?

Bad filters on the main board or a bad AUX REMOTE jack on the back of the unit (also part of the main board) re the cause of this problem.

Try plugging in any jack that will fit into the AUX REMOTE jack on the back and then pulling it back out. This may fix the problem or remove any dust that may have collected in the jack. If this jack has something plugged into it (or goes bad) the TV will no longer have remote control operation (because it thinks an external remote box is being used). If this does not work then the main board will need replaced.

Note, many repair techs will think the IR board is bad (the Infra-Red Receiver board) at the front of the TV, but this is usually not the case with this model.

Hope this helps, please rate my solution.

THANK YOU ! THANK YOU!

I had the same problem with my LG 42LC3R 42" LCD TV and your solution solved the problem. I simply plugged in an RCA stereo jack to the AUX remote port on the back, removed it and that solved the problem. Aparently, dust or something got in there. How simple!

I had just got off the phone with LG, and because the TV is out of warranty, they wanted me to bring it to a service center far away for evaluation. Quite a task, given I don't have a box for it nor a car to take it. You're solution made my day!

I have a 42inch sharp aquos LCD tv and there is no power. The power button keeps blinking. There is no picture and sound. What is the fix to this problem.


Power problem are cause by many reasons, i.e Power supply circuit, Lamp driver circuit and most often the TV detects an error cause by power surges. To protect TV from further damage most LCD TV have protection circuit built internally. If this is the reason of your LCD TV not powering On, an error data must be reset back to zero.
To change data you will need to access the service mode and change the value of lamp error code to zero (0). Entering service mode requires a trained TV technician. Changing data can cause more problem to your television. If you are not qualified to service your television, please do not go to service menu codes. Moreover below are the process, pls do so at your own risk.
* Unplug the TV * Press and hold the {VOL -} + {CH+} buttons located on LCD TV unit (not in remote control) Note: If above didn't work, alternately use (VOL -) + (TV/AV input) buttons located on LCD TV unit (not in remote control) * While holding the above buttons, plug in the TV. * The TV will turn on with the "K" or "K123" appears om screen. * Use {CH+} {CH -} buttons to go and display the service menu. Note: If above didn't work, alternately use (VOL -) + (CH -) buttons. * Search for "LAMP ERROR menu" from the displayed service menu by using "up or Down cursor" from remote control, or alternatively use "CH - or CH+ to select "LAMP ERROR" * change it to zero (0) value, using {VOL+} or (VOL -) on remote control. * Turn the set off to exit the Service Menu.

You have a pair of head phones? On the back of the TV there is a CONTROL input jack. Unplug the AC on the TV and rapidly insert and remove (fully) your head phone connector into this jack. Do this about 10-20 times. Plug the TV back in. Does the remote work? If so, put a piece of scotch tape over the empty CONTROL input jack. Dust gets in this jack and messes up the remote communication. I hope this helps.

It might have been blown out by the lightening storm. that happened to two of my tvs that were plugged in during a lightening storm. they both, and two dvd players, would not work after, but the ones that were not plugged in were fine. You should unplug your major electronic equipment during a storm, unless you have a power surge plug/equipment.

LG 42 LCD no sound or picture


Did anyone find out the solution for this??????? I have the exact same problem with my LG 32 LCD. I only had it for a year and a half, and the green light blinks a few times and it shows no picture. Not even a red light when the tv is off. The same thing happened a couple weeks ago and by some miracle it started working again.
