Mitsubishi VS-5075, the screen is white with a small picture at left. If I push pip on the remote it goes dark, push it again and I get the small picture on left side.
I've been through the menu and can't get the full picture back. Can you please help?

Re: pip only on screen
Try hard reset first==Unplug ac cord overnight,
then try again.Possible signal board trouble--
Practice visual acuity technique==look for CRT
coolant leak on circuit board.
Also suspect PIP PCB==can be by-passed by a knowledgible tech.

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.
1. VERT 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 ELECTROLYTICS (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).
If the source to the PIP input is a color signal then the PIP display will be color. PIP sets have two video sources one goes to the main screen while the other goes to the PIP. it all depends on what the format of the signal is being sent to each input. This is quite normal.
rule number one about all vs chassis with vertical can pip boards
take them out and throw them away
i could fix one but you couldnt beleive me
and it wouldnt be worth your while
do a search on your modle number until you come up with instructions on how to add two caps to the pip board connector to bypass it
until you do this you are wasting your time
Mitsubishi ... we're still building Zeros
