I've had a Sony FQ70 for a few months and overall I'm very pleased with it. However I have recently noticed a strange sort of red colour smear appear at the bottom left of the screen. It is only really evident when it is a white line on a dark background. http://homepage.ntlworld.com/steve.blencowe/tv/tv.jpg The above is a picture of the TV in WS mode displayed a grid. The colour bleed can be seen in the bottom left but disappears towards the top or right of the screen. Is there anything in the service menu I can access to alter this? Thanks.
