My tv keeps loosing channels and saying channel does not exist. If i do get the channel it is not a clear picture and the wind up loosing it
You can try a factory reset. search on line for mitsubishi model number owners manual.

The green CRT's (color picutre tube or color wheel, or ballast) will need to be tested for replacement.
It is quite common with these tv's
You will need an ohmmeter and or voltmeter and test each component for currency and accuracy

There are two and sometimes three very large IC’s that control the convergence in a big screen set. I think that you have two that are on the board in the center of the set. They are secured to a very large aluminum heat sink.
There are two ways to repair intermittent connections on the convergence IC’s. I usually remove the board with the convergence IC’s on them and then and solder the connections. The other method is to tilt the circuit board and solder them while still installed in the chassis.
If you remove the board and repair the connections, be careful to remember which connections need to be made when you replace the board. Mitsubishi uses a lettering system, so it should be easy.
If the problem remains after you have made the repair, it is possible that the pins on the IC’s have become loose. In this case the IC’s need to be replaced. I have seen this on several occasions.
If you choose to repair the set yourself, be very careful of the high voltage that can be stored in the capacitors, and CRT’s. This voltage can be as high as 30,000 volts.
I hope this information allows you to resolve this issue.

the DM board is failing and it is no longer avail sorry

I know this is an old thread, but I would like to post this information in the hope that someone will find it useful.
I just finished fixing this problem on my 1994 VS-6061... the problem is the PIP (Picture In Picture) board located on the Power Signal board. The PIP board contains the numbers 530B552. I bypassed the PIP board by following the directions I found at the following link:
http://forum.doityourself.com/entertainment-center-tvs-stereos-vcrs-dvds/130383-mitsubishi-cs-35301-rolling-picture-problem.html
"Plug in a 4.7ufd @ 35v filter cap (+)at pin 5,(-)at pin 11. Plug in a .01ufd(any voltage) between pin 7 and 9. Just plug the caps into the socket, where the PIP board was mounted (they don't need to be soldered). Just don't let the leads from the two capacitors touch, as they cross each other. The 0.01 cap is non-polarity, so either way it plugged is fine. Basically you will bypass y-signal through 4.7u, in pin 5, out pin 11, and bypass c-signal in pin 7, out pin 9 of the PIP socket.”
The bypass requires 2 capacitors: One 4.7ufd @ 35v and one Non-Polar 0.01ufd @ any voltage.
Remove the PIP board, then plug the two capacitors into the socket where the PIP board was mounted: plug the 4.7ufd capacitor with (+)at pin 5,(-)at pin 11 and plug in the non-polar .01ufd capacitor between pins 7 and pin 9.
If there is a ground wire (possibly brown) soldered to one of the tin cases on the PIP board, then you should connect this ground wire to the PIP socket either at pin 2, 4, 6, 8 or 10 which are grounds of the socket.
This PIP board was used in many Mitsubishi televisions and they were plagued with problems...This is why many of these older Mitsubishi televisions had similar problems…
Good luck
