Hello, I recently received a Toshiba 56h80 rear projection tv from a friend. He swears it works when he gave it to me. After transporting the tv home in the truck, when I turn the tv on, I have audio but no video. Instead the screen is white with diagonal, rolling black lines; not even the menu will display. Any ideas what the cause of this would be? I have some experience with electronics and repaired a panisonic rear projecition tv (IC circuits) with the help of this forum. Thanks!
Anybody? I'd really love to fix this thing. If it helps, I get the rolling black lines on all inputs except for the composite inputs. No picture on composite inputs, but solid black scren.
