Check in the Audio section from your Main Menu, there is a setting to switch the internal speakers on or off, you might have it set to the "off" position & therefore no sound, if not you have a problem with the audio section of the TV & this would need to be looked at by a qualified engineer.

This is not a sensor problem. The problem is inside the main system control circuit section. Some voltage loss may cause this type of problem. Contact any experienced service technician. The fault location is a skilled work, and not an easy one for a user.

You either have a faulty 24vdc circuit in the power supply, defective inverter, or a bad back lamp(s). The inverter boards will be on either the far left or far left and far right, if your set uses two inverters. Proper troubleshooting will need to be done before the fault is isolated.

If it is under warranty, follow the contact directions in your manual so that LG can get it fixed. Otherwise, contact a repairman.
