If everything else on the remote works, most likely the PWR function on the remote is not working.

This may be a problem with the conductive rubber membrane under the button, or the matracy circuit is not reading the function due to any number of problems.

You can call the manufacture parts rep to see if it is possible to have parts for the remote. Most of the time, they are not worth to service, and parts are not sold to support remote control service. You will most likely have to order a new remote from the manufacture rep.

I suggest to NOT buy a universal remote. They rarely can do more than the most basic functions. Many times universal remotes have different issues with different models of sets.

Why is there a beautiful picture but no sound and cannot change input?


Re the sound, make sure that the mute switch is not on.

Re the input, did you try changing input at BOTH the tv and remote controls. Could be the remote source button is not working.

According to the spec sheet for your TV (see attached link), the only video files it recognizes and plays are MPEG-4 (files with extension .mp4) or DivxHD (files with extension .divx). If your video files are not of these types, you can download a free video converter PC application to convert your files to the two types that your TV can play from the flash drive.

one or more of the tiny switches on that board with the controls is bad--either replace the board with the controls or just use the remote.

The plastic buttons will seem fine--it is the tiny switches under them that causes this issue.

Unplug it for about an hour to let it reset itself and try again, if it still has problem then you will have to open it up or take it to the repair shop. The power supply module will have to be looked at first to make sure all the voltages are present. Right now the 5vdc standby power supply is working and may be partially function processor.

37'' LG lcd tv, no power


I just want to clear things here.
The stand by light will remain on whenever the tv set is turned on by a button on the side of the tv.

Then use your remote to turn on the tv, but wait as it can take 10secs before you get a picture.
