Hi I have had my LG RI-28CZ10RX for a year and a half now and today when I switched it on the picture came on for a minute or two then slowly greyed out to a black screen. I still get sound but no picture. Anyone know if this is a common fault with this set? How much it might cost to fix? Bit aggreived that its decided to bust 6 months after the 12 month warrantry Anyone had any luck with LG paying up even though its not within the 12 months? Cheers for any help.
