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?
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!
