How to bypass a MITSUBISHI PIP MODULE

It is possible to repair most of these but damage from the leaking capacitors can sometimes make this tricky or impossible-


Here are the bypass instructions:

Remove back cover and locate pip board to the left of the set--one wire (usually green) is soldered to the metal shield.

The board is plugged in and you have to release the tabs at the bottom to get it out.

Locate the pins on the large plug (should be 12 pin plug)

You need to cut the copper foil traces with an exacto knife on pins 5, 7, 9 and 11. They need to be free of the board.

You install a 4.7 mfd filter cap to + on to pin on 7 and negative lead on 9.

You install a 4.7 mfd filter cap to + on pin 5 and negative to pin 11.


It should only take a few minutes to do this. You will have to remove the board from the set. I have done this a lot of times--Mitsubishi gets 30 dollars for their instructions to do this and no longer sells the board.

The reason the board fails is all the tiny surface mounted filter caps start leaking and fail.

Rolling lines for first hour or so...


It's the one in the metal can, and you can't by-pass them. Very difficult for a layman to replace. It's to the right of the tuner, about 6x6 in size.

Mitsubishi 60" I believe 1997 Model


You need a new PIP module. Surface mount capacitors have leaked out electrolyte and damaged the PIP PCB.

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

whats a quick solution


The problem may be related to bad capacitors on the PIP module. This is a commom fault as vertical sync runs through the PIP board and this is the symptom of the pip board having bad capacitors the TV rolls.

picture has horiz. lines


There is no vertical hold in the tv circuits now adays. You may find a vertical center or a vertical height. Your problem sounds like (if it has PIP Thats Picture in Picture) its in the PIP module and its a small module that stands up and most models of Mistubishi this module is no longer availabvle. The problem with the module is the small pana caps are leaking and ruins the PC traces. I have heard that theres a kit available on E-Bay to jump out this module. Now if its not the PIP model then it could be a few capacitors in the vertical sweep circuit. Also the B+ feed off the Flyback that supplies voltage to the vertical output IC could have a bad or leaky capacitor in the circuit. If your not a tech or solid state troubleshooter theres not much you can do and SHOULD take this set in to a repair center. Good Luck
