Question about LG 37LC7D 37 in. LCD HDTV
All of the buttons on the side of the TV work perfectly. The remote is not able to control anything but the remore works perfectly on another identical set in another room. How do I unlock the set without the remote?
Bad filters on the main board or a bad AUX REMOTE jack on the back of
the unit (also part of the main board) are 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.
