The missing board is driver for the deflection , are any board photos,
schematics available, what cost would this deflection board be?

cessna,
Actually that does help narrow it down a bit.
Seems that these boards were used in both the VS-400 and VS-401 sets.
The numbers on the boards would more than likely be 935C10901 for the power
board.
Signal board would be 935B06802, and the Main board is 935B06504.
Later on Mits added another digit to their part numbering system so that the
listed board part numbers would have an additional "0" on the end of their
numbers. This little factoid is almost useless at this point as Mits doesn't
have any boards for these sets and haven't for quite some time.
Anyway, this is about an '84 model anyway. Are you quite sure that you want
to undertake trying to get this set running? You most probably will find
that the CRT's will be worn out by this time in their life. Quite a few
replacement parts will be difficult to find if maybe not available at all.
I'll take a look around in our boneyard to see if there are any boards this
old still laying around, but I don't think that we are going to get that
lucky.

Which board(s) do you think could be missing?

Do you have a "home" page that you could upload a few pictures to?

Try that and let us know.

Good Luck,
Bill Jr

OK, a tag on the side of the cabinet, indicates possible projection tube
numbers VT0729B22, a power supply board has 93C10901.2.3.4.5.6.7.8.9,
the tuner has ENV 5677062 and 295P22701, another board video? also has a
93Bxx- similar to the other board, what else would help?
and Thanks for your interest

How about checking the part numbers on the boards and see if one of us

can

decipher those to a proper model number. Then you may be able to get

some

useful information.
BTW, even with the back missing they usually had a little white sticker

on

the main board that had the model and serial number on it.

Good Luck,
Bill Jr

one is repairing any more
