One question, with your username, are you a private pilot BTW just saw a
VS400 setting in a scrap pile but have no access to any of it's components. "cessna" wrote in message . .. Need service manual, ckt boards for a Mitsubishi projection Tv model unknown (rear cover missing) made mid '80s - early '90s, can email pic Thanks |

Yes, a private pilot with electronics as a second hobby, looks like no
one is repairing any more Arthur Jernberg wrote: One question, with your username, are you a private pilot BTW just saw a VS400 setting in a scrap pile but have no access to any of it's components.

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 "cessna" wrote in message . ..

I'll check that, however one board is missing, several boards have part
numbers starting with 85xxx I'll get more numbers and get back. Bill Jr wrote: How about checking the part numbers on the boards and see if one of us can decipher those to a proper model number.

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 My encrypted email address is NLA due to spam. "cessna" wrote in message . .. 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 Bill Jr wrote: How about checking the part numbers on the boards and see if one of us can decipher those to a proper model number.

The missing board is driver for the deflection , are any board photos,
schematics available, what cost would this deflection board be? Bill Jr wrote: cessna, Actually that does help narrow it down a bit.

Humm, that must be it, there is no board with a flyback, didn't find DD,
but DA, DE, DL, DC, and wires to the deflection yokes R G B, are all unplugged, I could have missed DD. you Florida? Maybe I should find another to tinker with ? ? ?

Yes, I'm in the Orlando, FL area. Cheers, Bill Jr |
