Rolling Screen on Mitsubishi Rear Projection TV – Model VS-5071
Mitsubishi Rear Projection TV
Model: VS-5071
Manufactured: March 1994
I am having a problem with a fast rolling screen on the above tv. I’ve tried to make as many observations as possible to be helpful.
Observations: Done while synced up with working tv for comparison, so I could tell what the scene really was. Tried all following observations on component and coaxial inputs.
With screen of white snow:
-The snow looks fine, no funny colors or blotches.
-The green on screen text is stable, no jumps, rolling, or double images.
On Black Screen:
-The Green Text jumps slightly and has a shadow/double of red text offset about ¾” to the left.
-Text does not roll.
Color Movie Screen (dvd):
-Screen roll (seems bottom to top) rapidly.
-Text is the same as on the black screen.
-When playing a scene with black background and white text, the white text seems to have a green tint to it, with a slight red shadow.
Watching TV:
-Imaged stabilized (stopped rolling) briefly when commercial had top Third white, middle third black with small red text, and bottom third white.
- Also stabilized when screen was black with white image (no color at all).
-Orange appears red and gray appears bluish (I think, image rolls so hard I’m not for absolute sure).
-Rolls on black screen with small white text (dish music channel)
VCR Color Movie:
-Always rolled on color screens. Even if paused, unless next situationà
-Stops rolling if tape is paused and has a lot of white static bands on it.
-Blue vcr screen (fill for no signal) appears correct color but has rolling shadow bands over it.
VCR Black and White Movie:
-Black and white film still rolls if playing, but if paused on certain scenes will stop rolling, still a little jumpy, but I think that is the vcr not the tv. Seems to be more likely to stop rolling on scenes with larger patches of white.
- Black and white movie when paused and stable has pink and lime green lines following the outlines of where some white and black meets.
-Pink and green lines appear on the screen at the same time, but do not appear on the same points. i.e. Where black and white meet will either be a pink or green line, but not both on the same boundary. Lines are about 1/8-1/4” wide, solid color, not striped, and up to 12” long.
That is all I have observed so far, that I know might be relevant. I can take pictures or maybe short video clips (don’t know how refresh rate will affect my camera) if that would be helpful. I appreciate any help anybody can provide.
Thank You,
Joshua

Awesome! Looks like that person (eddwhatley) was very very knowledgable of this type of work.
It definetly takes years and years of experience to learn, and hopefully there will be a pro on this site that can help people out.
