TV remote control circuit contact problem

If I insert the battery in to lg TV remote control the IR emitter sends a signal, without press any button on the remote control, how can I solve this problem?

Hi @ayaya

Check if any buttons are stuck down.

If not you will have to open the remote and clean the motherboard using Isopropyl Alcohol 99%+ (available from electronics parts stores) as something is shorting out the tracks on the board that the buttons make contact with when pressed.

Here's a video that in principle shows what to do.
