Hi, I have a Samsung LE37B650T television which I've had for about 4 years. It has worked very well indeed; however, all that it displays now, is a grey screen. There is sound. On switching on, for about a second, the screen is black then instantly turns grey across the entire screen. Is there anything I can do about this ? I chose this TV on the basis of the excellent reviews that it received - but a 4 year life, doesn't seem much. Given Samsung's position in the market, shouldn't I be expecting better than this ? The TV has not been abused in any way & is in 'as new' condition. So, can it be fixed ? or would I be best served, in going out and buying a replacement ? Probably made by LG.
