Question about Sony Grand WEGA KDF-55XS955 55" Rear Projection HDTV

1 Answer

KDF-55XS955 Blue lines

We have had this TV for about 16 months. Suddenly today after we we watched a DVD, we noticed these blue lines coming out of the bottom right corner of the screen. They are not perfect horizontal lines...somewhat like a 'mass', if you will. I have pictures, but can;t figure out how to post them. We have never seen them before, and at the moment only see them when that area of the picture is dark. Can someone tell me if this is the color convergence that need to be adjusted? And if to get to that little panel? Thanks!

This is an optical engine problem - it needs to be replaced - it will only get worse. Sony has had problems with the optical block and is extending the warranty for this problem. (this is a LCD projection tv - there is no convergence)

Blue spot on screen center. Peoples faces and show blue tint

if you have a Sony LCD projection ..Theres good chance optical block needs replacing .This spot will get bigger and will eventually cover most of screen the longer you use it .needs repair.If there is no warranty on this unit..I would estimate repair around 6- 8 hundred dollars ..

I have the same problem. The repair guy said it's the optical engine and you may as well replace the set as pay for the repair. First time I'm glad I bought the extended warranty. That's another story. Zonieal
