[rtstorm]

Hello, my friend have this TV and it have strange behavior. TV work ok then sudden it will change channel, or turn volume up to max or switch between inputs. He thought that remote is problem and he try to put out that battery but problem still appear.

Have you ever experienced this kind of issue?

Disconnect your IR sensor board from the main board after turning it on. If problem goes away then its a bad sensor board. If the problem persists, then you have a bad main board.
