Frustrating Picture Issues - Horizontal Blue Lines

I have a Toshiba 46H83 that is only about three years old. For the last several months multiple thin horizontal blue lines across the entire screen from top to bottom have appeared, typically when first turned on. On occasion they will go away but lately the lines are more intense and they are always somewhat visible. There are now only moments of clarity. I have pulled the screen and cleaned the lenses and saw no real issues, nor did it have any affect on this issue. I have noticed that the lines are affected by vibration, if I tap lightly on the top of the set it may clear up for a short time, but most likely will re-appear. This problem is present regardless of inputs; digital cable, DVD, VCR, ECT. I have tried different power supplies also with no luck. I have called the only qualified service outfit in town with a response we can come look at it for a fee. What I would like to know if anyone has seen this issue before? Is there something I can do to fix it or investigate further? Is it worth paying a field service tech to come look at it? Or do I need to cut my losses and buy a new TV? Any advice would be greatly appreciated. Thanks

Toshiba 46In HD Rear projection TV Vertical lines on screen

We also have vertical lines with our JVC 62"... turning it off and letting it cool down is the only solution. For us, we know it's a problem with heat. We simply are wits end on fixing it. added two additional fans, a exterior fan to blow heat away from the back of the tv, pulled everything else away, etc.... Anyway, goodluck.

Model 55X70 Toshiba Projection tv

dont know about warranties but horizontal lines means your horizontal frequency which runs about everything has drifted off sync and if too high or low it will activate shut down circuits in high voltage and power suppy, even causing HOT transistor to short. good luck and call a tech.

Horizonatal lines on Toshiba 46H83

If the repairman you had look at the set is used to working on projection sets, have him come back and Re-Solder Connector Px801 (Edge Connector) On The G-Hyper Module. (Pins 1 And 2 Of Px801 probably needs to be Re-Soldered) Otherwise, find a different repair person.
