I paid over £1000 for an lcd tv around 3 years ago and after about 2 years it started showing like dark shadow running vertically ,these have got worse and also has some other issues with viewing .The tv has been pretty crap to be honest and the picture quality even when new was not as good as my two sons who both have Flat screens in there rooms,I put the model number into Google and up came complaints from loads of people with the exact same problem and the same complaint at the lack of concern from Sony, who refuse to recognise the problem ,The problem seems to be polarising of the backlight which means a new panel which is not worth the effort or expense so looks like a new TV instead .I have had a similar problem not long back with Sony with the PS3 ,which everybody that owned one had ,and again they were no help so There will be no more Sony products bought .Just a rant and warning for anyone considering a Sony product ,beware their customer service is not good at all.
