Your model is the VZ8 that doesnt have the pip board it has an IC for control of the PIP. So your problem has to be in the video or deflection circuits You can get a service manual off this link that I am part owner of if you need one. We also help by giving free support to help with the diagnosis and locating parts. This is a free service when you purchase a manual and we email the manual within minutes of placing your order. Its listed as VS60707 and sells for 10.99 its the full factory service manual.
Heres the link if your interested.

I have sound but no picture on my mitsubishi VS-45VA2, what can I do to solve this problem?


Well, today may be your lucky day. This is a 200.00 repair at least, but I'll attempt to help you for free. Most commonly on this set the pip module fails. This is a small standup board mounted on the signal pcb. There are 2 plugs that connect it to the signal board. These plugs are VS and VA. First, Disconnect the power to the tv and remove either the front or rear cover. Use good lighting. Disconnect small standup board from signal pcb using a small screwdriver to undo the two clips at VA and VS connectors. Pins of the VA connector are marked on the board so you can tell which one is pin 1 through 11. Simply jump a small wire from pin 5 to pin 11 and a small wire from pin 7 to pin 9. Make sure the wires do not touch and this will bypass the pip module for testing. With pip module removed and 2 jumpers installed plug set in and turn on. The set should now show a picture but the pip will no longer work. Hope this helps. Good luck, Russmann.

Tip

Do it yourself Mitsubishi PIP module BYPASS


This applies to most Direct view and some projection sets made in the 1990's.

While it is possible to repair in some cases this problem it is quicker and cheaper just to bypass the module--you will no longer have the PIP function.

Here are the bypass instructions:

1.) With the set unplugged remove the back cover and locate the PIP board to the left side of the set--one wire (usually green) is soldered to the metal shield. Unsolder the lead and set it aside.

2.) The board is plugged in and you will have to release the two tabs at the bottom to pull it out.

3.) Locate the pins on the large plug (should be 12 pin) on the bottom of the board.

4.) You need to CUT the copper foil traces with an Exacto knife on pins 5, 7, 9. and 11 near the plug so they are no longer connected to the plug.

5.) You install (on the bottom of the board) a 4.7 mfd filter cap with the + on pin 7 and the - or negative on pin 9.

6.) You install (on the bottom of the board) a 4.7 mfd filter cap with the + on pin 5 and the - (negative) on pin 11.

7.) Reinstall the PIP board and make sure the caps do not touch anything near that board; solder the ground wire back to the shield.

The reason the board fails is because the surface mounted caps dry out and or leak onto the circuit board---there are a lot of them.

I have seen shops replace some of the caps and get it to work but sooner or later more go bad so usually it is better just to bypass the board and not have the PIP feature anymore.

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.

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

Mitsubishi projection TV VS-4561 Vertical Hold issue


Good Day, Maybeitstime:

Joe the cheapest way is to repair it yourself and this is what you need to do:

VERTICAL JITTER/HORZ UNSTABLE-CHECK 'GE' CONNECTOR PIN 5 FOR 1VPP Y SIGNAL INTO PIP PCB THEN CHECK 'GE' CONNECTOR PIN 11 FOR 1VPP Y SIGNAL FROM PIP PCB. IF SIGNAL AT PIN 5 IS GOOD AND PIN 11 IS CLIPPED OR REDUCED. CHECK ALL ELECTROLYTIC's (I.E.C7001, C7014, C7026, C7036) AND ALL CONNECTING TRACES TO THESE CAPS FOR CONTINUITY 2. HORIZONTAL TEARING, VERTICAL JITTER. SIGNAL RELATED CONDITION. APPLY FOLLOWING CIRCUIT CHANGES ON PCB-SIGNAL: A. REPLACE R2K8 WITH A 1K RESISTOR (BASE OF Q2B2). B. REPLACE R2K3 WITH A 47 OHM RESISTOR (IC201 PIN 50). C. ADD A 100PF CAPACITOR FROM BASE OF Q2B2 TO JUNCTION OF R2L0 AND R2K6 (GROUND). As you can see this might be over you head but for a 1994 model you did get 14 years of watching TV enjoyment. 'Might think about replacement. Good Luck, big IRISH.

Hi i have a 93 Mitsubishi model# ck35402. I was told that the pip had went out. was hoping someone could walk me through on how to remove and reroute


From the bottom of the main board locate IC 2004 between the PIP module and the tuner. Remove the jumper between pins 2 & 6, then jump pins 6 & 7. Next , pull the pip module from its socket and toss it. The symptom for a bad PIP module could be black screen, no picture, blue streaks, wavy or jittering picture.The audio will not be affected. Make sure the symptom fits the cure before you bypass the PIP. Good luck!

Mitsubishi VS-50707 50 in. Rear Projection...


There is a quick test you can do to determine if the problem is in your PIP module, using two 4.7uf/50v electrolytic capacitors. The PIP module plugs into two connectors on the main board. Remove the PIP module, and on connector VP on the main board (the 11 pin connector), use one cap to jumper from pin 7 to 9 (negative lead on pin 9); and use the other cap to jumper from pin 5 to 11 (negative lead on pin 11). If the PIP module is bad, you will now have video. The PIP module has surface mount capacitors that go bad. Just make sure you solder a small lentgh of wire to the capacitor leads to prevent them from shorting as they cross over each other. Just plug the wires into the socket no need to solder them.

This is a pretty commom problem with this model. As it has several bad capacitors that go bad. If you have no solid state repair experience, and to save you from any high voltage shocks that can kill you, i would highly advise you to contact a local authorized repair shop to assist you in the repair of this set. As much as you really want to repair this set yourself, To do so would be tempting faith! As a Tv set these days are all solid state and have no user serviceable parts inside of them and to try and experiment with them, could be very harmfull and a risky thing for the user to do. Please find a trained tech to assist myou in the repair of your set. Good luck , and please report back on how the set was repaired.
