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

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.

The service manual is available at www.elektrotanya.com

Hi,

Thanks again to everyone who responded.

Based on information I found searching the web, I returned the TV to the
customer (no charge) because I have a small business and I didn't want to take
the risk of investing in a T-CON board (one possible cause of this problem).
