Default Samsung UN48H6350 - Going Crazy

Hi all. I've got a Samsung UN48H6350 that suddenly started going crazy.

The volume goes all the way up then down, inputs keep changing, it turns on and off. It's constant too. I unplugged all inputs from it thinking it might be a CEC issue with no luck. Unplugged it overnight with no change.

I did read something that said this is fairly common with some Samsungs. If this is a board swap, I was wondering if anyone knew about this issue and could tell me what board needs replacing.

Thanks!

Im not familiar with the power button and Ir set up on this tv, but if they are separate, unplug the button setup and use the remote control. This was a common problem on older LCD Samsungs.

Thanks for the reply.

To me, it looks the IR and controls are tied together.

What I just did was unplug the cable coming from the IR/wifi/button module where it plugs into the main board. I fired it up and it does the same thing.

I'm assuming this is saying I need a new main board?

Thanks again.

I would check voltages on mainboard connector with cable off and see if you have any voltages on the pins.
