It is an LVDS issue. Could be caused by anything in the LVDS circuit. So starting at GPU then MUX then coils then LCD connector. Give the GPU some heat and see if the problem disappears, not reflow just 100C or so.
By re-soldered LCD connector do you mean replaced?

Thanks Duke. Didnt replace connector yet but ll start from there. After GPU heat little bid.
