Question about LG 42PB4D 42 in. Plasma HDTV

The TV will not respond to the remote and

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?

Hello,

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.

Regards.

My 42PB4D turns itself off and immediately back on. Interestingly this happens a lot but never when watching a dvd nor in the wee small hours of the night.


There can be several causes for this, few of which you can do anything about. However, a few things to try:

1) Replace the batteries on your remote control.
2) Try resetting the logic functions on your tv by unplugging it for a minute, then plugging it back in.
3) Try covering up the infra-red receptor on the front of your TV to see if you're getting unwanted signals from the receptor. taping a piece of foil over that area is perfect. If it doesn't stop after doing these two things you'll probably need to take it to a shop.
4) If this does stop it, then look for unexpected signal sources. Have you added a remote control extender? Added a new device to your audio-video system? Changed to a new remote?

I hope this helps. Joe

Can't find the codes to programme satelite reciever on my tv remote. Please help. I have a Motorola HD reciever with SHAW Direct.


On most universal remote control, you will find the procedure to enter the builder code OR a procedure to pass through all the codes of the remote, one by one and pass to the other TILL you find the right one. It happen to me numbers of time and i've always trick it this way! Good luck.

Tv works fine for few minutes, then the tv wont respond to remote


There's clearly a heat-stressed component in there, possibly something as simple as a badly soldered joint in which a gap opens up due to heat expansion.

It's not that old a TV so may be covered under warranty. If not it's going to need to go into a repair centre where they can find the fault and repair or replace the affected part.

Re-soldering a bad joint isn't always possible in which case the circuit board which it's located on gets replaced instead.
