Ive learned a bit about this model in a day, as my nieghbor bought a new Sony and gave me this one. The repair shop was going to charge $600 for the board but then couldn't come up with one. I didnt find a board but did buy two more Mits 65 s both for $750 and one of them almost like new. I have the first one about back together as it appeared had leaked coolant fluid on signal board. I cleaned with alcohol and think it might. I like the picture they have so I would still buy a board if could find one. And will try to make two of three last a few more years or all of them looks like would be pressing my luck. I think I could part one of them out and pay for the other two. Let me know if you think we should have a visit as I am by no means an electronics wizard. I used to be a race car builder, so they could possibly end up with wheels on em. Thx for the come back have a good one.

boards for these sets are never available any more from Mitsubishi----google PTS---they repair, rebuild all kinds of circuit boards.

Mitsubishi WS65807


The Color Signal on this Model Series travels across three boards before being sent to the CRTs. The 3DYC Board, Signal Board and the Terminal Board. Most likely, the 3DYC Board or the Signal Board is causing the problem. I have had intermittent solder connections on the 3DYC Board to cause no color problems. This Board plugs in and is located on the left front of the Signal Board as you look from the rear of the chassis. If you feel you are not up to the task to work on the set, call a Mitsubishi professional. To find one, call Mitsubishi at 1800-332-2119.
I hope this helps,

Picture with signal applied is purple and distorted/choppy


The board you seek is the doubler (2HDW) module.. a lot of time reseating the board will solve the issue. If HD still works, this board is likely you problem. This board upconverts all non HD signals to hd to put onto the screen. IF HD doesn't work, you more likely need a signal board. This board has all the settings on it and is much more difficult to replace.

We have a Mitsubishi DLP and the timer light is flashing on and off and I cannot turn the power on or off on the TV


Bad signal board, DM module and or formatter board. Try replacing the signal board first. About 50% of my fixes with flashing timer LED was solved by signal board replacement. If this doesn't work, then try replacing the formatter board. And if still don't work, then DM module must be replaced.

Mitsubishi don't have a real answer behind these failures. I know and I've tried. Do have two of them just came in my possesion for repairs. One has same problem and just put in order for new signal module.

Mitsubishi tv model VS6061 rear projection with rolling picture.


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

Dvd plays fine sound/picture...No sound or picture with cable input


John,
To answer your question no, there are no fuses associated with the tuner input - through the "F" connector jack.
You have there a V26 chassis which has, among other things, standard digital and analog signal inputs. If one works but not the other - and you've verified it's not the cable then the only alternative is the signal board, Mitsubishi p/n# 930b923002...
But don't rush out and buy this puppy, it's a fairly expensive board and there are alternatives to replacing it new or used - PTS Electronics can rebuild this board for half the cost of a new one and most techs use PTS for that reason.
My best advice is to have a qualified shop estimate the repair and if they decide that the signal board needs to be replaced and quotes you a price ask them then about having it rebuilt.
Also take the unit to them to save the pickup/delivery charges and ask for your estimate in writing...
Hope this helps!
Bill

Mitsubishi WS-55908 Convergence Issue; need IC 7A00, Panasonic MN12857k MA2


Sorry, but when the coolant leaks down onto the small signal board, that board will never work right again. The fluid penetrates the board itself since the board is double sided and has many feed-throughs. The fluid gets under the surface mount parts and just eats through the copper traces, part leads and board itself. After trying many times to clean and restore those boards, not one has ever worked right again. The boards are NLA from Mitsubishi, so the set is done.
