Disconnect one ribbon cable from t-con to panel and see if it stays on. Then the other.

Probably. Just throwing things out to try. Seems strange it comes on in the same time each time.

Disconnect main to control board and connect jumper to autogen on control board. See if you get a test pattern.

Re: Lg 55uk6950plb

I told you what chip I think it is. Maybe some alcohol and some side lighting of the chip will enable you to read number.
