Need help w/ Toshiba 40H80 problem (1 Viewer)

[Raleigh Smith]

I have a Toshiba 40H80 HD ready TV. Paranthese lines have developed on my TV. They were not on the TV when I purchased it. Months after owning it about 4 or 5 lines that looked like this ((((( developed on the left hand side of my screen in the center. The outer ones were larger and they became smaller as they went toward the middle of my screen. They were only a couple of inches. Over time they have gotten larger, spread further towards the center of the screen and developed on the right hand side as well. The problem looks similar to this:

((((((((((((((( ))))))))))

I have spoken to a Best Buy technician 2x and have been told that what I'm seeing is the lens. That this is normal on all projection TVs and he can do nothing to fix it. If this is true, please let me know. If it is not, can someone help me get this problem corrected or point me in the direction of documentation that I can use to strengthen my position? I emailed Toshiba and am waiting for a response regarding this problem as well.

Thanks in advance for your assistance, advice, and suggestions.

A few things to check for:
(1) Clean the inside of the set. If you are gentle and careful, and if there is a removable panel to let you reach inside, you can do this yourself. Pay attention to the three lenses on the CRT's down below, and to possible cobwebs suspended in mid-air.
(2) The screen has two or three layers. They may have separated leaving an air pocket. There is probably no easy-to-explain sure fire way of fixing it, but it may depend on a trial and error process of loosening the perimeter screws that hold the entire screen in place, pushing the layers together at the middle, then tightening the screws again.

Allan, Thanks for the info. I'm not too comfortable w/ opening up my TV. I wouldn't know where to begin. But I'll give it a try.
