Sony LCD TV Model KDL-32XBR4 with Colored Vertical Lines Across Screen

[[email protected]]

Hi,

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

According to Google, your set has a WAX3 chassis.

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.
