    Sony TV, KDL-55EX621, white/grey screen with lines

    I have this 55" Sony LCD with a video problem. The sound seems ok and the screen lights up but there is no picture data. The screen has large blocks of gray & white with darker horizontal bands scrolling upwards. See the photo below. If anyone has any suggestions, please let me know what other info is needed. Thank you in advance.

    looks like panel failure.

    Bright band looks like maybe liquid damage on the tab, from cleaning maybe

      Panel failure likely not fixable

        Would this mean that the boards are still likely to be good?
