Question about Mitsubishi WS-65907 65" Rear Projection Television
When I first turn on the TV the picture comes in with the colors seperated for a few minutes and then they snap back in place. The colors also seperate occassionally while watching TV. We found out by accident that if I hit the bottom of the TV the colors will also snap back in place. Can you help me?
If you open the TV from the back. Look toward the front, right. It is a large IC, usually two of them that look alike. All the cable assembly's are coded so it should be easy to disconnect enough of them to flip the large circuit board and get at the underside of the STKs.

By now I hope your TV has been fixed. If not...Don't adjust anything! You have an intermittent problem on your convergence circuit. You have to be comfortable with soldering. Unplug. Find a TV tech, tell him (her) to open up the back of the set. carefully flip over the circuit boards and re-solder all the pins on the STKs. Its a cold solder joint. Done.

The issue you are having could be caused by your television needing the convergence adjusted. During production your televison has the three picture tubes that are converged to form a single image on the screen. Over time these can come out of adjustment.
If you go to this link http://download.jazel.net/misc/filecache/b8/b89bca4c8b740315d378e8ed030461c5_1227-517SeriesOwnersGuide.pdf and check pages 57 and 58, it gives you a very detailed guide on adjusting your convergence. I am aware this model number is slightly different than yours, but I own a 47" Mitsubishi and this is the exact procedure we use to do our convergence so I am confident it is fairly universal.
The reason that they might snap back into place when you hit the base is that they are actually three different colored picture tubes or rods. By hitting the unit, you are moving these. I would suggest doing convergence on a regular basis and to avoid hitting your tv. :)
I hope this helps!
