Hi christisfree

Try using a different cable that you connect from your source to the Projector.

A colour change is normally a faulty cable , but if the problem persists after changing the cable , then you might be in for a new Mainboard.

Try the cable and get back to me on this one.

It doesn't show red color. i tried to do factory reset. but still problem.


1.After turning on the projector, press "+" and "-" buttons on the control panel
simultaneously for 3 seconds and release the buttons when screen goes blank.

2 Press "+" and "-" buttons again to exit the diagnostic mode.

3 While in Self-diagnostic mode, the screen will run a seven-color-cycle test as
following:
Red--> Green--> Blue--> White--> Watchet Blue--> Dark Green--> Yellow.

Ensure that the colors of the test pattern are correct.

Contact Dell if the colors are not displayed correctly.

I have a green tint on my Proxima DP5900. The menus seem to maintain the proper grey color along with have red borders around things that are supposed to be red. S-Video, VGA and all other video inputs...


it's the input board. if it was anything in the optical engine, the menu would be discolored as well. try resetting all the settings to factory default. if that doesn't work, see if there are any loose cables or loose solder joints inside. if all that is good, then you'll have to replace the board. now the bad news: proxima has no parts for that model. sorry.

The color is not correct. No red. A lot of blue


if you have an lcd projector, the red lcd panel is not working or one of the filters are fried. if you have a dlp projector, the colorwheel needs replacing or the main board has an issue.

My video yellow plug works fine, showing correct video colors yet, the red blue green connection is only showing picture in a pale green


Yellow is composite input if RGB is not working it's probably a cable/output problem try with a different device first.

Vp800 LCD Projector has dark blob on display.


blow out any dust with canned air. chances are there is an object blocking the image. or there is a crack or burn spot on the 2nd fly-eye lens (diffuser). the first one is right next to the lamp (if you remove the lamp, you'll see it). the second is right on the other side of it.

Manual for lightware vp800, and i can't get the sound to work


Try changing to your S video wire input.If you hear a cracking sound it could be you've blown your speakers.It depends on your application but I run all my DVD equipment through my stereo system,just run the same video wire to your stereo and select that input on the stereo .And yes they do have remote controls,try ebay where you can get another vp800 w/remote under 100.

Colour problems with projector


In short If the reds show as red, The greens show as green & Blue shows as blue. I would say thats as good as it can project. It's hard to judge color without seeing it for ones self but usually DLP projectors that use a colorwheel do not have perfect color.
