LG 3D TV 47LM4700-UE unending Input Scrolling

LG 3D TV 47LM4700-UE Continuous Input Scrolling.

After a recent close lightning strike my 3D TV (LG 47LM4700-UE) has a strange problem where the input keeps constantly flashing /switching from one to another at high speed. So obviously I can't watch the TV as the input keeps changing.

Ive tried unplugging it, took batteries out of remote/ replaced. Nothing works.

I assume this is the main board?

If it is, how hard is it to replace?

Answer this question I have this problem too

Is this a good question?

A lot of these TVs have different boards, and the model number doesn't identify it specifically enough. I'd suggest opening it up and posting the model numbers on the boards. Take a close visual inspection at everything, particularly the power circuitry, to see if you can identify any toasted components. Feel free to post some photos here!

Where are these model numbers that you refer to? I have the back off.
