Tv will not respond to any remote control functions
RE-Program the rc to the TV

Unplug power cord- safety first!
open backcover
check powersupply- top center right is p.s.
top left side of powersupply you'll see 5 capacitor 3300uF 10V.
see any pop up on top? replace it All with same rate or 16v is O.K.
do not use temperature rate 75c. Use 105C.
if you know how to solder. you could save $300 at least!
SOURCE: LG TV 32LB9D VOLUME STUCK AT 100, NO RESPONSE TO REMOTES
The fault may be on the control board. Sometimes the button switches can be stuck, or there may be something causing some conduction on the control circuit board. It is also possible to have a component failure that is causing a continuous command to keep the volume to the high position.
Something that causes failures of controls in TV sets is when people clean the screen, they spray liquid cleaner on the screen. Some of it drips down in to the controls and on to the circuit board. This will usually cause damage, and thus the set will require shop service.

IR senor may not be bad. Try using a different remote (universal) and program to TV. If universal remote works and your doesn't, you may need to purchase a remote instead of IR board. If you confirmed that the IR board is bad then replacing the IR board will fix the remote issue. IR board is an easy fix. Just open the back cover out and it's located right in the middle toward the bottom of the TV.

sparrow00, your fix worked for me, and I think I know why. The 1/8" remote input jack on the back of the TV has electrical contacts inside that are probably there to sense the presence of a plug-in remote. When they detect the insertion of this plug they disable the front panel IR (infrared) receiver and the TV only responds to this plugged-in remote and the buttons on the TV itself. After some period of time these contacts get corroded and the circuit is no longer completed between them. The TV now thinks an external remote is plugged in, and it ignores its own front panel IR receiver.
When you plug a 1/8" plug into this remote socket on the back of the TV it wipes away the corrosion. When you remove the plug the internal contacts conduct properly again and the TV responds to its front panel IR receiver. For best results you should plug a 1/8" headphone plug into this remote jack and twist it a few times, then pull it out and repeat several times. Repeat every frew months or whenever the TV acts up.
Thanks for your solution!

Read an earlier post about cleaning out the remote sensor connection on the back of the tv, tried that out and it works. Awesome
