Question about Sony VPL CX4 Multimedia Projector

Open Question

Horizontal blue lines in image

After the projector warms up, I get horizontal blue lines throughout the display. The image is still there, it is just a noticeable color shift.  Is my bulb nearing the end of its life or is it a projector problem?

    Hey, i am having the same sort of problem except that I have blue and green horizontal lines along the projector and I am using a Marantz VP11s1
    . It is only noticeable in dark images (e.g. black) while in very light contrasts, it is hardly noticeable. Can anyone help? Please?

I have a similar problem with our projector. It help to reverse the output for some reason. When reversed, all horizontal banding disappears.

Hi Andy!

Yepp, you can do that, each and one of your projectors have separete settings. So you can run one hanging from the roof and the other one standing on a table if you want. How the picture is showing depends on how you set up the the settings in the specific projector. The the signal that comes to the projectors are always the same, its only the settings on the projector that can change that.

Good luck
Nic

White areas in the image are yellow and the black are blue-green


you have a few issues. first is the yellow in white. the light filter on the blue lcd panel is fried due to excessive dust and heat. unfortunately, you may have to replace the whole optical engine. as for the flashing horizontal lines, the power supply isn't cooling down and the caps are drying out, causing fluctuations in voltage. so, replace the power supply.

NEC LT35 color problem


If you're trying to project video, then the unit needs professional service. If you're trying to project from a computer, you may have a loose display cable, broken pins in one or both ends of the display cable, or broken conductors (wires) within the display cable. The computer sends its image information as a template of RED image components, GREEN image components and BLUE image components with the projector overlays to create the complete image with blended color values. (The computer also sends HORIZONTAL and VERTICAL synchronization signals, but those don'e affect the color content of the projected image.) That's why I'm suspicious of the display cable, conductors or pins.

White vertical lines in image w/ 2 inch black bar horizontal.


the black bar is from the light tunnel collapsing. the white lines are from the colorwheel or the main board has a cold solder joint. replace the tunnel and colorwheel and have the main board looked at.

Horizontal lines traveling up screen


Sounds like a ground loop on the video signal. Try using a ground lift on your computer and or your projector.
