I have the same problem as several people on the site. My new 42 in LCD set (42LB4D) has stopped responding to the remote control. It worked fine for a few days (like 3) when we brought it back from the store, nut now it does not respond. Any suggestions will be greatly appreciated.
LG had a run of bad diodes in some of there lcd tv's recently but have been good about fixing those effected units. Tv's will not respond the remote and may turn on and off by itself and cycle thru channels.

Check the remote control for its infra-red emission. Check it with fresh batteries. Check by pressing all the buttons on it; and see whether all of it generates infrared signal while pressing. If it is found OK, check and replace the infrared sensor inside the TV. If you wish to get some details; check the site linked here. It has details about how to check a remote control; by one among the post. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ If the remote control is found OK; check and replace the infra-red sensor inside the TV. Contact any service technician.
The first possibility is that the new remote control is a dud out of the box. It can happen. Another possibility is that the remote sensor in the TV has failed. Then the remote is transmitting, but it's not being picked up by the TV. (The lights are on but there's nobody home.) If you can, return the new remote to the store and exchange it. Then, if the set still doesn't respond, you'll need to replace the remote sensor.
is it the factory remote? if it is check to see if something is blocking the sensor on the tv, clean the sensors, if it is a universal remote alot of new tvs have codes that even some of the new universal remotes dont support. if thats the case you will just have to make do.
Your problem is not with the remote but rather the circuitry designed to respond to the signals transmitted by the remote(s)
Find out what board has the circuitry that responds to the remote signals and replace that board. Got a better idea?.
If very expensive then you have 2 choices - deal with a remote less set or get a new one.
