Panasonic PT-LC56U Multiple pictures

I have a projector that is projecting a picture for each color. They are not aligned so it makes the picture blurry and almost like a tv getting bad reception. I am not sure what is going on and how to fix it. Any ideas?

Picture went dim, new bulb installed still dim.

before installation of a new lamp your projector need a service due to dust your LCDs and analysis block not pass on the light properly and now you get a multi color background and very dim image.
so you service your projector to a technical person

I have two Panasonic PT-LB10VU projectors doing the same thing. They project find with RGB, but when trying to project a VHS tape through video, the image rolls or has multiple lines running through it. ...

first of all you replace the present video driver VHS tape and try any other dvd driver or any other video device if problem exist then the main board of you projector is faulty.

Solution: open the upper over remove 5 screw back side of projector.
disconnect the panel ribbon cable.Remove lamp cover with 3 screw remove main board with 4 screw and 8 connector. put it face down on a table and use a table lamp for more light.
check very carefully the area I show in the picture with red arrow there is a resistor no.R041(on resistor 750) is burn out or black replace witch 75ohm resistor and check around the resistor if burn any other component replace with the same after repair of main board fix the all part of projector as you open. Power on and use any video device other than your VHS tape maybe the high voltage comes on video output.
if fault exist then need to be replaced the main board. good_help_11.jpg

Distorted picture.

Is the menu text clear on the screen, when it's focused correctly. Or is that also distorted.
If the menu text is OK then the picture signal is dodgy. could be due to a bad earth lead on the video cable.
Is it distorted on all signal inputs
