Question about LG 32LC7D Television
The IR receiver in the TV may have gone out, but check the remote signal first.
Testing remote control:
The remote control puts out IR (InfraRed) signal that human eyes cannot see, to find out if the remote is sending out the signal or not you just point the remote at the digital camera’s Lens (Digital Camera can detect IR), you should see flashing light on the camera’s screen when any one of the remote button is pushed. If you do see the flashing on the camera, then the problem is in the TV IR receiver or the main logic board; more troubleshooting with scope will be needed to look at the signals.

The flashing blue light shows that the TV is receiving I.R. from the remote but doesn't mean that the signal being received is recognized by the Samsung. If you have a "universal" remote then your TV code may need to be re-entered/reprogrammed...changing batteries in a "universal" will usually require it to be reprogrammed. Also...because of the remotes construction (rubber membranes with carbon dots that short across PC traces) I've seen certain buttons stop working altogether.
