Fair enough. What is a chassis? Is that the light engine or some other part?

I believe its the entire back part with all the component boards attached to it. I am not sure to be 100 % honest. From what I do know is that the signal board and power supply board are part of it somehow.

I actually watched what he did one time, and just to replace the ballast, he had to remove like 50 screws and take off damn near the whole back of the TV. Seems like they would make things a bit easier to access than that.

Who thinks about service? That's somebody else's problem! Service is always the worst on the first gen of anything...

The chassis represents over half of the display, very expensive, and there are few parts left after that one! It is a huge metal can with a world of wires coming out of it. Very difficult to service so many opt to replace instead along with providing the Mits 6 month warranty that comes with it.

These can be difficult to service depending on the problem and lamp lighting is probably one of the more difficult to diagnose on this particular chassis.

Does the Mitsubushi have a self diagnostic program? If so, how do I access it?

They do. It flashes out digits with the power light creating a code and then you refer to a chart. This is best left between you and your service center when you actually have a problem. Bear in mind it is very similar to idiot lights on your car; they don't tell us much and only get us pointed in a direction.

Have been, and am currently going through exactly what everyone here has gone through. Bought TV over three years ago and has beeen nothing but trouble. Thank god for the extended warranty. Went to Fry's today, where I originally bought the TV, to get yet another loaner, and there were 10 Mitusbishi's all returned for repairs/returns.
Repair guys have told me on multiple visits that they work on these TV's all day. Had another visit for my second power pupply board and before they came to my place, they had to do the same thing to the same TV right down the street. Not only did my power board go out again, but the DM board, and now I'm dealing with a chassis having to be re-built. Over three years this TV has been broken down for over three months. Three years, three bulbs.
Customer service, non-existant. Mitsubishi, doesn't care. Fry's keeps putting the same defective parts being back in. Stay away!

I worked at Best Busy stores promoting DLP technology for Texas Instruments and I met many consumers who were picking out a new TV b/c their Mitsubishi DLP failed during the warranty.
When their sets were made in El Toro, CA next to the El Toro Marine Base they were reliable
great sets but they moved production to Mexico and quality went down the toilet. In these third world plants, there is a high turnover of assembliers and the Q & A reflects it.
I have a Yamaha DPX-1 DLP projector that is 7 years old...yes seven...and I have had no problem other than normal lamp changes (done under warranty). The unit was made in JAPAN.
I know surgical instruments made in Germany are 1000% better than those made in India
and I think where it is made makes the difference.
