Toshiba 51h83 projection t.v. scrammbled lines across the screen.
The t.v. has a bunch of scrammbled lines from top to bottom. Sometimes a little stomp on the floor, are a shake of the t.v.(which i know is not good) clears it up for a bit. Just trying to get a little advice on what to do. It looks like when theres something scrambling your tv. The picture is there, but the lines make it a pain to see and rough on the eyes. I havent taken it apart are called the repair man yet, just trying to get some advice on what the issue may be.
I've seen this problem before with Toshiba sets. Normally it's been caused by the hyper module.
Usually, the set is worst when first turned on and clears up some, if not completly after it warms up. The problem does get worst over time.

this is normal with rear projection tv's its from long usage when the tv isnt always in full screen mode. you can sometimes fix this by replacing the bulb/ or the color board for the projector. also you can replace the screen as it seems like it may also be do to image burn in if it wasnt always in full screen mode. (did this for my uncles Mitsubishi projection tv)
I've had the same problem for about the last 6 months. My workaround which was to leave the tv on 24 7 and just turn off the TWC service box. But now the symptoms are vertical dark lines going all the way across screen. My guess is that it will cost more to fix than worth it. I paid @$2000 for it new in 2004. Technology has gotten better so I may just go out and get a Samsumg for considerably less and be way better off. None of Toshiba's products had done well for me. 2 laptops, 3 tvs, etc. have taught me this.
I have a wild guess. I have the same tv and channel 72 is the proper channel to watch tv on. I don't know why, but maybe try channel 72 instead of the usual channel 3. Good luck, maybe a quick fix, maybe not!
