Question about Mitsubishi WS-65809 65" Rear Projection Television
Mitsubishi turns of periodically. We have to wait 5 to 10 minutes before it will go on again. If we try to soon, the green power light goes on for one second and then off.
Do you have the tools required to solder electronics? Do you know how to solder electronics? Have you been trained in CRT safty ? Do you know about High Voltage safty? Is the tv Model number WS-65809? Do you know how to perform static geometry adjustement on a WS65809 if needed? Do you know how to perform static convergence alignment on a WS-65809? Do you know how to perform fine convergence adjustement to a WS-65809?
The answer is :yes yes yes yes yes yes yes yes
You can retreive an error code of 23 or 24 right after the tv shuts
itself off .
There is a 95% chance that I could tell you what to solder , no parts need to be replaced in your television and you would not have to pay someone to repair it.

I had the same problem. I deducted that if my TV worked fine for an hour or so and then the colors became bad (green, people's faces purple...), it must be a overheating problem. Simple logic, right? So, I picked up a few tools and a small vaccum and went to work.
I went first for the main source of heat: The lamp. Just a few screws, and I removed it. The lamp cage has a fine screen to prevent the dust to cover the lamp. Mine was covered with dust! And the fan behind the lamp was also covered with dust! Bingo!!! That's my problem! I cleaned everything and vaccumed all the air vents on the the back of the TV. I put the lamp back and checked that the fan was working. The TV works like new since!
Before you are out of a TV for days and spend an arm and a leg for a "Technician" to fix it (replacing expensive parts that didn't need to be replaced in the first place), try what I described above first. It's very simple and it takes only 15 minutes.
Since my TV is 2 1/2 years old, I purchased a replacement lamp. I know that one of these days it will burn out. I'll be ready and my TV will be working again in 15 minutes!
Since my problem was solved, I didn't go to the next step. There must be one or two other cooling fans inside the TV, but they must be working...

Testimonial: "YES IT IS A HEAT ISSUE(IF YOU HAVING GREEN SCREEN ISSUES LEAVE THE BACK COVER OFF AND PUT A SMALL FAN BLOWING IN THE LIGHTBULB AREA.PROBLEM SOLVED"
I suspect a bad connection/dry joint in the power supply.
Look for regulator I/c's on heat sinks. They are favourite to get dry joints and anything that is heavy like transformers and chokes.

SOURCE: My Mitsubishi TV turns on
I had the same problem with a similar tv.
the problem with mine was that one of the input components would over heat and cause it to shut off. also in your case it could be the projectors over heating or even the bulbs are starting to burn out.
i hope this helps you good luck.
