The red is cutting out. white=blue+green+red. without red, you get blu+green, or cyan. if this was an lcd projector, i'd say it's a burnt light filter, the red lcd, or the lcd has come unplugged. but since this is a dlp projector, you have either a dmd board issue or a main board issue. either way, it'll be pricey.

Green screen on VGA with Viewsonic PJD5122


VGA is separated analog signals in Red, Blue, and Green. Under normal cases, you'd be able to change the cable, source, or input port and resolve the issue. Unfortunately, if the green tint persists with all input ports on the projector (The two blue ones are Input, the black one is output. There is a potential that attaching input to the black output port could have caused the damage), different sources, and different cables, then it's likely a problem with the projector hardware itself and would require warranty service or otherwise repair or replacement of the projector. If you have an alternate way the projector can be attached, then try that (Such as SVideo), otherwise there may not be any good solution in this case short of checking the guts of the system.

Our club owns a Canon LV-7240 which has worked OK. Last night we showed an NTSC DVD from Europe and no red showed. We could see what the colours ought to be on the laptop screen. On the big screen,...


Can't answer for the menu issues, but I can garuntee this is not a problem with brightness, contrast or sharpness, and very unlikely that you'll find a solution in the menu. What is likely is that the VGA wasn't plugged in properly initially. When the signal is going down the VGA it's broken up into 5 seperate signals, Red, Green, Blue and 2 sync signals. What is likely is that the green and blue pins havn't properly made contact either inside the projector or inside the laptop. This would also explain why it worked when you tried later because it made the connection properly. I would suggest trying again with the same laptop, if it does it again, try another PC without moving the projector or the VGA connector that's plugged into the projector. This will atleast narrow down your problem, but it doesn't sound like a problem with the projector to me. Also try plugging the laptop that wasn't working properly into a monitor (this will test the laptop)

I have a VT465 and the projection back ground is yellow and I can't get it to be white


If you are talking about the actual image that is coming from a laptop being yellow instead of white, then this is caused usually by a bad signal cable running between the computer and the projector.
To be more specific: All colours in a projector get made up in some way between red, green and blue. White is all of these colours at maximum, yellow is made by red and green at maximum but no blue. If your image is Yellow when it should be white, then the blue signal information is not reaching the projector. This can also happen within the projector or computer itself but is less likely. If your using a VGA cable (15 pin cable) then blue is run through pins 3 & 7 (positive and negative respectively), see if your cable is either missing these pins on either end or if they are bent, although it's more than likely within the cable itself. You can test this theory easily by trying to put something blue on screen, if the blue signal isn't getting through then it'll appear black.
If changing the cable doesn't solve the problem try testing the computer by trying to use a different one, and test the projector by plugging in a monitor or another projector.

If you are getting a yellow screen without sending signal and just trying to get the "no signal" or "no input" screen white, then this won't be the case.

Hi there, my dell projector 1800mp is not projecting an image on screen and it only black lines across. what should I do to fix it?.


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.

3While 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.

My picture is coming out in black & white instead of color. What am I doing wrong


Two possibilities come to mind...!st: Verify that your component video cables are correct ie red to red, blue to blue and green to green. Check this at both ends of the cable. In the dark, people often get the green and blue cables reversed. 2nd: Gently shake your projector. If you hear things rattling around inside, it's more than likely your colorwheel has shattered.

Large dot in the middle of the projected display


there is a burned-in spot on the polerizer light filter for the blue lcd. it makes sure the light is blue coming through, that's why it is black on a blue screen, and yellow when the red and green are the only light showing through. it needs to be replaced. pat # PFiLW0213CEZZ.

No display on expantion vga port for projector


The problem might be related to your native screen resolution. The C702TU laptop has a resolution of 1280 x 800. Most projectors do not support this resolution and if you cloned the main display, your projector cannot sync at this resolution. Look for an option to output a second display )instead of cloning) within your display settings. If your projector is plugged into your VGA port and turned on, Windows usually detects the second display automatically. Change the resolution on the second screen to something like 1024x768 or 800x600. These resolutions are supported almost universally across projectors.
