Question about Mitsubishi WD-73732 73" Television
I purchased my WD73732 projection TV from Circuit City on May 18, 2007. This weekend on June 13, 2009, the color on the tv started acting up. The best way to describe it was the color was gone but trying to come back in. This causes the screen to flicker constantly almost like the color is trying to restart but won’t. Vague hints of colors also flashing. Behind the flickering the images are still clear (picture not otherwise distorted). If I turn the TV off for a few minutes it comes back on with good crisp color for about 30 minutes and then it goes again.
On the night of the 13th, I unplugged the TV and left it that way overnight. In the morning I turned it back on and enjoyed a good picture for most of the day. At about 3 PM on the 14th the problem came back so it appears to be a time/heat sensitive problem. This is my second Mitsubishi projection TV (my 60 inch still going strong with never a days problem after 10 years) and I am devastated to be encountering this problem after only 2 years (I already had to replace the lamp about 2 months ago).

SOURCE: problem with color
Yes you have a problem in the red crt driver board. Most likely the driver transistor is failing. This is a component level repair, so if you have no experience with TV repair, play it safe and call in a trained tech to assist you in this matter. Good Luck

You need to replace the "light engine". This is very very difficult. You need to take it to a repair shop. But this will be very expensive. Around $1,000.00

This model series had a odd problem that caused this. It was the Hoizonal wire connctors for the yoke. If my memory serves me right, the Yoke wire harness went from Yoke to Yoke and plugged in at the casing of each yoke. What I found is the solder connection on the small board of each Yoke was intermitent. Please be careful if you choose to tackle this. It is in a HV Area.
Hope this helps,

The convergence amplifiers need to be replaced.
This set may have one big amplfier chip rather than two.
The chip(s) will be on a big aluminum heatsink.
There may be bad resistors related to these chips, as well as one or two fuses that are open.
I've replace many convergence amplifiers.
If you have good soldering skills and ac test fuses and resistors, you can do the repair yourself. Caution that even with the set unplugged, there could still be dangerous voltages present on some components.
Search this site for specific convergence repair related to your set.
