I purchased the above model second hand last week and for the 1st 2 days it was fine. Brilliant picture/sound, I was over the moon. On the 3rd day I turned the TV on and after about 30 minutes the screen went white, but I still had sound. Now every time I turn the TV on the picture is fine for between 2 and 30 minutes and then it goes to a white screen again. I've been told by a TV repair shop that it is the lamp(s) and been quoted £695-£895 + VAT to repair it. Could there be other reasons for the problem? There is no way I am paying that sort of money to get a 5 year old TV repaired but it looks fantastic in my lounge and I would be really gutted to see it go. let me know if you think I have been misinformed and there are other reasons for the fault. Thanks in advance.
