When I first turn on my TV (motorola DXC3200 HD box) I have white horizontal lines across the screen, also very distored picture on the left side of the screen.
This disappears and reception becomes excellent after a few minutes. I have tried adjusting the picture on the TV
(Samsung LNA630), have changed the HDMI cable, rebooted the HD box and have also had Shaw reboot the box. It works properly for a while but keeps reverting back to the start up problems sometimes as soon as the set is turned on again, sometimes the fix or fixes last 2-3 days.
Has anyone else had this problem and what did you do to cure it?
