We have a toshiba projection
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.

Toshiba 50H72, replaced IC's, but colors still not
The error codes only indicate the convergence circuit is not working.
In this set it is VERY important to check the 1.8 ohm resistors, if even one is open the convergence will look bad.
These sets are not real easy to get at the chips etc, and I learned the hard way a long time ago to check all the resistors, if needed unsolder one end of each of the 1.8 ohm resistors and be sure all are GOOD.

Most Hyper modules are no longer available from Toshiba.
Hyper modules go bad due to problems in the power supply.
Which also needs attention.
We have developed a method of repairing the modules.
We are a Toshiba dealer in Milwaukee.
Note: What you read on the Internet is only a guess. You guess at you own expense and risk.
A dealer assumes that risk for you and provides a warranty.
