A while back my TV was turning itself on and off. Cutting to the chase, I discovered it was my TV remote control when the problem ended when the batteries were removed.......so...how to fix it.
Step 1: Open the Remote
I opened the remote and noticed there was an "oil" on the rubber key pad and circuit board.
Step 2: Swab the Parts
I took a swab dampened with alcohol, and cleaned the "oil" off.
Besure to get into the recesses on the rubber pad.
I reassembled the remote and it worked perfectly!
This has also worked for my cordless phone keypad.
