i have exactly the same problem as the other people who have written about this tv model on the forum and there seems to be manty many more out thereon forums reporting the same problem that sony will not acknowledge.
there are dark lines running down my screen and a dark shadow line about an inch think on the right hand side of my screen, this was more noticable when watching football. my tv is not under warrranty anymore but is only 2 and a 1/2 years old. it seems that sony have created their screens to only last this long as lots of people have the same complaint.
i have just rang sony and i have been told that "there is no known problems with this model" that is rubbish as clearly there are a few of us just on this forum with the same pronblem. So we are paying about £1000 for a tv that will only last 2.5 years. i am disgusted with the lack of help and support from the sony call centre staff who basically said i need to get it fixed myself and i need to book it in with a service engineer. I suspect this is a problem with the panel or with the screen where a replace ment would cost you more than getting a new set. it would cost me £45 just for someone to come out and tell me that without even having it repaired. as a dedicated sony buyer over the years i cannot believe that my most expensive buy has only lasted 2.5 years.
WHY IS SONY NOT DOING ANYTHING ABOUT THIS PROBLEM??
