    LG 55UN6955ZUF. Help

    Hi
    I recently acquired an LG55 UN6955ZUF
    When I cycle it on it has backlights and audio.
    No video just the light blue hue of the backlights.
    I've replaced the main board hoping it would take care of the problem but, same outcome.
    I've started taking some reading from the buffer strips on the panel itself but I'm not sure what the reading should be.
    Here's the current readings

    LEFT SIDE BUFFER
    VCC33. 3.35 VDC
    CLK 70 ohms
    DI 130 ohms
    GND. gnd
    CS 3.27 VDC
    DO. open
    WP. OPEN

    RIGHT SIDE BUFFER
    VCC33. Open
    SCL. Open
    SDA open
    GND GND

    Has anyone had issues like this.
    The tv is only around 4 months old

    Thanks in advance

    Unplug the ribbons and see what you have in the picture.
