I have to suspect the model number listed here is not correct as that model is a older rear projection set?

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.

jnagle,

By horizontal I will assume that you mean there is no vertical drive and you just have a line across the screen. If this is the case then I have a tip at https://www.fixya.com/support/r7887362-crt_projection_tv_lost_vertical_drive which should help resolve your problem.

Thanks for using FixYa and for the great rating. Please consider a testimonial. Thank you.

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.

Above is your service manual, i believe your problem will most likely be the STK device Stereo audio output amplifier, developing a fault, either that or the power to the Amp is compromised, so as always start with the Power supply first and work out. Replacing the STK device is not too hard, you need a desoldering tool, and a good 40 watt soldering iron with a fine tip and some rosin cored solder.

Also have a look at this master google link, have a look regarding the stk replacement in particular.

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.

No,this tv have chemicals,it sides could destroy those sensetive chemicals,causes it to distort ur DLP CRTS tubes or worse cases chemicals leakage to the circuits boards,destroy both DLP CRT tubes and circuits boards together.Best way is to tranport it up right.
