Sony Bravia TV Picture Problems, Need Some Help

I have a Sony Bravia TV (model KDL-46W4100) and recently it started having these colored squares and distortions in the picture. It only changes the color of the area, the picture coming from the movie/video game/cable is fine. I cant find the same problem like this on my search of the internet but maybe someone has seen or experienced this and has some advice on how to fix it.

Looks like a classic board failure.

The one with the decoder and RAM on it. While these are no TV repair forums your TV repair person will likely change out the big board in the set.

Answer
Colored squares

Yes, I had the similar problem with my Sony Bravia, although the colored squares were visible all the time. Technician came out and diagnosed it as a panel failure. Replacing the panel costs more than the TV did new. TV was 2.5 years old when squares appeared.

Ouch.

Seems like either board or LCD, if out of warranty, it's toast.

Am I having the same problem?

I've owned the same Sony Bravia KDL-46W4100 for three years. In fact I own two. Six months ago I started getting one square / rectangle of discoloration. Then two. Now there's tons. I've done the full firmware upgrade and it didn't solve the problem. Like the previous poster, is there anything I can do? Is it worth having someone come by and see if they can fix it? Or is the cost not worth the repair and I should just get a new television?

Sony Bravia TV picture problems

I have a Bravia KLV 46W410A , 2 1/2 years usage with absolutely the same problem. I think 2 and 1/2 years usage is to little an usable life for a tv set, and ,worse, for a Sony top ranked model!! I will have a visit of a service man tomorrow and I will let you know his diagnoses.

It's the T-Con board

The T-Con (timing & control) board needs to be replaced. I did mine for a little over $100 (used) and about an hour and a half of time. It's usually located near the top with a few ribbon connectors from the panel going to it. From my research this sounds like a common issue with these Bravias so the question is would this be worth it to you if there was a good chance the same issue will just happen again?
