My remote went out, so I thought. Have tried 2 more universal remote and none of the codes are working. Tried a code search to no avail. Any ideas?
If you have a video camera - turn it on, and while 'filming' - have someone point the remote at the camera, and press a button.
If the remote is sending out the infrared signal - you will see the light thru the camera. If the remotes are working - then it is something in the TV.
The TV would need a visit to the shop - for repair - if it is worth it.
