I own a 5 year old 40" sony bravia lcd tv, When


This sounds like what I managed to do to my screen, even though I knew better. Is there any chance you layed the screen face down at some time?

Even though you can still watch it OK, you probably have hairline fractures in the screen face (NOT the screen itself- be thankful for that- the cracks are in the screen coating). LCD screens are a very thin glass laminate with a thin protective glass-like coating. When they are laid flat (like I did to connect cables) if the screen bears any weight, microcracks develop on the front of the screen.

I am sorry to say that the effect is permanent.

I have coloured vertical lines covering my Sony Bravia LCD tv screen. The TV is only 2 years old. I have sound but a very distorted picture. The cable company has checked and says it's a tv problem. I will...


I also have a 2 yr old Sony KDL32xbr4 that now has multi-colored vertical lines on the screen. I contacted Sony and they say they have "no known issue" of this sort for this model. I find this rather puzzling since I have found numerous postings on the web. They told me to try the factory reset. Whatever. Might as well have said "don't buy a Sony". 2 years! $1300 for a tv and it lasts 2 years! Makes me sick to my stomach.
