Have TV Questions? Ask a TV Technician
Hello, my name is ***** ***** I'll assist you. I'm sorry you're having trouble with it. I need additional info to troubleshoot the issue.
- What video devices/ sources (such as cable box DVD player etc) are connected to TV and does the problem occur on all video input sources?Thanks.
Thanks for the info, are you using LG TV remote or Satellite box remote to change the channel/ input source?
OK, we need to check the remote infrared signals output which will help to determine is it remote problem OR remote sensor on TV is defective that made TV unresponsive for remote commands.
Please get any digital or cellphone camera, press any buttons on TV remote while watching remote front tip through camera (as camera can see infrared light), do you see flashing light on remote front tip?
If so that means remote is working and remote sensor on TV has got problem that is why TV doesn't get remote commands. At this point you may please use control buttons on TV itself to operate it, push Input button to change input source on TV. If problem still persist then unplug TV power cord from wall outlet for 10 minutes to reset the TV, replug back in and press power button on remote or on TV itself to see if it works?
Please reply back with the result and if problem resolved then a positive rating to answer would be highly appreciated.
OK, try to push bit harder the control buttons that should work for non responsive buttons as this type of tactical switch got corrosion on contacts after some time and pressing it a few time bit harder will help to get it working again.
Regarding remote function it is confirmed that remote sensor board inside TV will need to be replaced to resolve the problem. I trust my input will help you out. Please feel free to respond if you have any additional questions.A positive rating to answer would be greatly appreciated, please click on 5 star on this page then click submit/finish button so I can get credit on website for my work.

I wanted to briefly follow up with you and see how the info worked, and see if that accomplished what you were looking to do!
