Re: unable to control channels or volume
Is the remote a universal? Make sure you select TV as the the device you are trying to control. You can also fix a wonky remote by popping out the batteries and mashing down all the buttons. This rids the remote of any built up electricity that could be hampering functionality. Also, the remote sensor on the TV is controlled internally of course so a power drain of the TV wouldn't hurt:
1. Unplug the product's power cable so that the device is not grounded to the house. Do not simply turn off the power-bar if one is in use. 2. Press and hold in the products power button for 1 minute to release the retained electricity from the capacitors and circuit board.
3. Plug the product back into the wall outlet rather than a power-bar to rule it out of contributing to the problem and turn the device back on.
What do the buttons on the TV itself do? Do they work properly? If not, the problem is going hand-in-hand with the remote and again, the problem is internal and service or a firmware update, if available, may resolve this.

Try changing the input device to something you are sure, works such as a DVD player. Look for any loose contacts in RC jacks/sockets/Cable. Look for jammed buttons on remote and/or on control panel. Try removing the batteries from remote and operating from the control panel of TV. If these are ok, Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.
it could be 2 issues: faulty remotes or stuck buttons on tv's keyboard. Where did you get 2 remotes? cable or directtv boxes? those are universal and must be programed to work with tvs. or, do you have 2 identical LG remotes in your household? either way, if you have kids on premises and lot of drinks carried around, remotes could be contaminated with fluids inside and malfunctioned. You must become a CSI and figure it out! Good luck and let me know the results. Alex's tv.
I hate to give you the bad news, but this is not an easy fix for a do it yourself-er. you will need the internal diagram to fix this. There is an IC (intregrated circuit) chip inside that has most likely failed. I would recommend that you take it to a qualified repair shop for estimate or repair. There is really nothing in this case that you can do to fix it yourself without the proper equipment.
if you have an external jack for hooking up a surround system you may try to route the volume through this type of device and control the volume that way, but this is just a temp solution. Best of luck to you, I hope this helps.
Just bought an LG 32" HDTV and have the new Samsung STB, with a Scientific Remote; the code in the remote manual for LG says to use 1005, but after trying it and many others, I used the "Find Code" set-up (991) and (990) in the remote manual and happened upon 1004 for the LG.
While this worked, the remote is a bit awkward, as you have to enter yet another code (998) in order to control the Power for both the TV and Box with the remote; the good news is that the instructions to do this are pretty straightforward and well presented.
Now, I can turn both TV and Box on/off with power button on remote, can change channels with remote and also vary volume with remote!
