Question about Televison & Video
You should try another remote to determine if the remote is actually defective, or there is a fault in the TV set. I have seen both scenarios, of either the TV was defective, or the remote was defective.
I suspect the remote to be defective more than the TV having a problem. The reason is that you can use the remote to turn the power on and off in the first place. This means that in the TV the IR receiver module, and the remote circuit processing to the uPC is responding.
If it is not the remote that is defective and the TV's IR path is responding, there are several other possibilities. There may be lockout function in the user menu that locks out the main controls from the remote. There may be some other type of defect with the uPC system controller. This can be firmware, or some type of hardware failure which would be a bad device in this area on the circuit board.
There are control circuits for the functions in your set. In most TV sets they are shared with the front panel controls. There could be a fault in this area as well.
Anything past trying another remote to verify the remote functionality of the TV, and checking the user menu for a lockout feature, will indicate that there will be the requirement for technical service.
