Every now and again the tv wont respond to remote. The remote works on friends tv (same tv exactly). suspect IR sensor on tv. How easy is this to replace please? Many thanks!
Replace the remote sensor. this component can be located just behind the infrared window at the front panel.

The IR sensor is in fact a "plug in device" .
The TV will have to be disassembled to replace the sensor.
You should make sure the remote is functioning before you do anything as drastic as taking your tv apart.
I am sure you have tried fresh batteries so the next step would be to hold down any button on the remote, the led light should have a faint pulse, it may be hard to see and you may have to go in a dark room but the led will pulse if the remote is good.
If you have a universal remote, program it for your tv and test functionality.
An RCA universal remote will work with your tv, if the codes don't work do a search with the remote.
If you decide to replace the sensor you should be able to find one at http://www.shopjimmy.com or http://partstore.com.
Let me know if I can be of further assistance.

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.

Most of the time it is the Main Board in the TV that the sensor plugs into. They have had many issues with this Board causing this problem. To be sure, you will need to call a professional.
Hope this helps,

SOURCE: Remote sensor on TV (LG 42PM1MA) seems to be broken.
Have the technician check for 5 volts on the remote IR Sensor if present the the Remote sensor has failed. Have him replace it to factory Spec's. No need to replace entire main board when the sensor is no more 5 dollars....
