Question about LG 42PB4D 42 in. Plasma HDTV
My LG 42PB4D TV will not respond to the remote and replacing the remote didn't help. The TV always works fine from the front panel controls. It responds intermittantly to the remote for brief periods, seemingly after the TV has been turned off for a while. When it does respond to the remote, all the buttons on the remote work. Unplugging the TV made no difference.
Neither new batteries in the old remote nor a new remote made a difference, so I believe it is the TV . Is there a remote sensor module or connection that could be bad?
If new batteries did not fix the problem, then it means the problem is either from the remote or the TV.
You need to do some diagnosis to confirm the source of the problem.
Remote: Check the remote battery terminal, see if its not rust. Also, disassemble the remote, can check the connection between the terminal and the remote board, see if there is no disconnection of any kind.
If after checking and all seems well, then it means the remote is defective. To confirm, borrow a remote, test it with the TV. If it works, then it means you need to replace your remote. But if the remote you borrowed does not work, then it means the problem is from the TV and not the remote.
TV: There is a sensor in the TV that communicates with the remote. If this sensor is defective, the remote won't communicate with the TV.
The TV sensor might have loosed contact from inside of the TV or it maybe defective and need to be replaced.
So do the above troubleshooting and let me know if the problem is from the TV or remote. If problem is from the remote, you need to do a replacement. But if otherwise, let me knows as well.
