    There is a small black curved internal line, like a hunchback camel, at the left hand bottom of the screen. I though it was a crack but its from within.

    Any cable or dish network gives a blurred picture and double-triple images (outlines) of every figure on the screen.

    Please help me understand.

    Ver doubtful the wii caused it. This is a common problem with all projection units the Convergence ICs only last around 3-4 years and they wear out in a instant with no warning what so ever. Its an easy repair if you can solder. If not the link I posted will explain how to solder even tell ya the correct solder Iron to get and where to get it.

    They dont list them by model you have to select your IC based on what yours are. You need two STK392-560 they are located on the D board at locations IC8001 and IC8002. Just click on the correct IC numbers to place your order the Instructions come with the new ICs and they set you up after purchase with a free email and Instant messaging account for free support. they give you all that info when they send the order confirmation email.

Colors are separated red, yellow and green so picture is blurred


Try using the Flash Focus to/or manually try to dial in the convergence. If you are unable to focus the TV using its convergence adjustment it's time to call the TV repair guy. Figure on between $250.00 and $400.00 USD.

Screen color/picture quality

You can access the menu by hitting two buttons on the TV itself at the same time. You then adjust by hitting the up/down buttons.

The double pictures u mention sounds like a convergence problem.

If adjusting the convergence via the menu does not work
you would need to order 2 parts and be able to solder. A rather inexpensive repair if you can do it yourself.

You have a convergence problem. Components are shorted out and must be replaced. Unless you're a technician, there's really nothing you can do at this point.
