I own a Hitachi 4:3 HDTV (model # 53UDX10B) and recently acquired a Comcast HDTV receiver. When I view the HDTV channels through the new Comcast receiver, I often get black bars at the top and bottom, as well as the left and right sides of the image. It's like looking in a box within a box. What is wrong, and how can I fix it?
I've had a Toshiba big screen hdtv for about 10 months and lately the picture has been flashing white for a second then goes back to normal. This is a rear projection T.V. that seems to already have burn in from the closed captions (two rows of little squares across bottom of screen)....Is my tv about to die on me?
