Switching source and pops up OSD menu randomly

Hello,

ANSWERS:

szalaco could be a faulty Function/IR board. Check connector CN3002 on your main board and see if it is clean and properly connected. If it is I'd start by replacing that. Part number is Samsung BN96-07270D and the board number should be a BN41-00990A
