Sony KDL46Z4500 vertical lines - Resolved.

[Aim]

Hi,

I had this vertical lines problem for the last few weeks (please see images).
I checked loose coonections around PCBS and tabs for LCD screen etc and had no luck.

After reading tge informaton on this site, suspected the TCON board and managed to buy a used one. Fitted the board yesterday, all OK now.

Thought of sharing the symptom images, hoping they would help someone to determine the faulty component.

Regards,

Thanks for posting. Looks to me like it would have been bad panel. Glad t-con fixed it.

Hi,
Yes.. I had the same doubt that it could be a faulty panel.
When I found out this TCON board has 4 processors, each controlling quater of the LCD panel, I took the chance to purchase an used board to try. The symptom was continously occurring on 3rd quater of the panel.

It looks as though you still have an issue. Just to the right of the Sony badge going up around a third of the screen?

Just to clarify, all images attached in my posting were taken prior to replacing the TCON board.

No Dick, I think those were his images of the fault symptom.
