Using a Dell projector, is there a way to get it to project white without any inputs, versus the standard blank blue screen? It goes white when searching for inputs, but switches back within seconds when...


Since you did not provide the make and model, you will have to pull out the manual and check the settings. It may provide you with a setting change for the background color. Perhaps you can connect it to a computer, open an new blank document and project the blank image to get your white light.

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.

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.

I see no red and green colors on screen projected by pjtx 100, the rest of the colors are visible.


If you are using a component video cable (Red, Green, Blue) you may simply be missing the Red cable. It may not be fully plugged in.
You can verify that this is the case by: 1. Unplugging all video cables 2. Plug in the green cable, you should see a black and white image. 3. Plug in the blue cable, you should see some colours coming through. 4. Plug in the red cable, you should see all colours properly.
If not, unplug the blue and red cables and plug the blue cable into the red port. The colours will look incorrect, skin tones will be blue. If the colour comes through the problem is the cable. If the colour does not come through, the problem may be the projector.

InFocus Projector-Searching


most likely it is your cable. If a for sure brand new cable doesn't fix it it is most likely the main board. Also try flashing the software again.

Sony VPL-CS5 menu will not display


Give input signal to the projector and see that if the menu appears or not on the screen.
if menu comes on the screen then put the backgroung color to blue, instaed of black.

if nothing comes on the screen, then the LCD panels are faulty.

Projector lamp shows blue on white screen


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.

Delay/ whitescreen when projecting video from laptop


1.
Connect the external display port on your laptop computer to the projection system, and then turn on the projector. For information about connecting external devices to your laptop, see the documentation for your laptop computer.
1.
Set the display resolution of your laptop computer to match the resolution of the projector system. First, on your laptop, open the Display Properties dialog box by using the Display icon in Control Panel, and click the Settings tab. Then, in Screen resolution area, move the slider to adjust the display resolution of your laptop. If you don't know which setting to choose, try 800 x 600 pixels; this is a common setting for many projector systems. YOURS sounds like 640x840.
3.
If you have audio in your presentation, connect a cable from your laptop's audio output jack to the audio input jack on the projector, and then test the volume by playing a file that contains sound.
4.
Start the Player on your laptop. If you want to only display the Player on the big screen, and not the desktop background, maximize the Player or set it to play your video using the entire screen (full-screen mode).
