I'm Sorry to tell you, that your TV needs a visit from a qualified Service engineer.
My 46in Samsung LED TV (UN46B6000VF) has started showing many red and blue vertical lines across the screen. I bought the TV about 18months ago. It happens with all inputs ) satellite, DVD, VCR, USB, etc... I've tried the self calibration to no avail. Any advice to get fixed would be greatly appreciated.
