    I am a TV service technician working on a Sony LCD TV
    model KDL-32XBR4 with colored vertical lines across the screen.
    I have worked on many CRT TVs, but not many LCD TVs yet.

    I don't have the SM for this TV. A web search was not
    very productive on the cause of this problem.

    Has anyone repaired a problem like this?

    Thank You in Advance, John

    Here are several Google hits for service manuals for sets
    incorporating the WAX3 chassis:

    Two possible causes

    T-con (usually behind a shield at the top of the LCD panel. The
    cable from the main board connects to it.

    Bad LCD panel.

    The service manual is available at
