We have a toshiba projection tv 50H72. we are getting picture distortions of lines verticle & horizontal. convergence has been rest, the only way to get rid of the squiggly lines is to turn tv off...

There is a common problem with this particular model that involves what is known as the"Hypermodle" this is a cuircit board that controls signal processing. The symptoms you describe sounds similar to this problem. This board has 11 very small parts call capacitors,that go faulty over time and get worse with more time. Ideally replaceing this board was the right thing to do in the past however since this was a common occurance the boards quickly became in short supply. Toshiba issued a Service bulliteen to shops on how to repair them. I repaired 2 of them a month at the shop. Now this is a repair that only the most experience tech should attempt. very small parts and easy to damage if not done right. Our shop generally charged around 250 to do this repair. most of the cost was in labor. but always ask if they have done this repair before.

Tv screen problem

It can be a problem with the light tunnel, if the upper mirror detached you get half screen.

It can also be a convergence problem, if one of the ICs is defective.

Toshiba 50H72 rear projection TV. NO Video

Bad caps and solder connections, especially in around the 9v regulator just about center of the defection circuit... Not a terribly expensive job and certainly worth the repair if the cabinet is in good condition...
