My projector has lines on the screen. new bulb didn't help


If this projector is connected by Component Video (3 or 5 wires) instead of HDMI, the most common color related problems are caused by having one of the 3 video cables (Red, Blue or Green) with a bad connector. If everyone is a green smurf the problem is with the red cable. If everyone is a red smurf the problem is the blue cable. If the green was bad you wouldn't see anything.
Another possibility is if the green is plugged into the yellow jack instead of green jack on the projector, you could see what you are describing.
If everything checks out, take the projector to a repair facility.
If you are connected by an HDMI cable, (combined with the fact you mentioned vertical lines not horizontal) then take the projector to a repair facility.
All of this assumes that you don't just have a bad Cable Box or Blu-ray player or Home Theater Receiver. (The source)

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.

Projects a pink background image. Have tried resetting to factory defaults and replacing bulb.


try a brand new cable. if that doesn't fix it then your red lcd panel is probably burnt or the lcd cable isn't plugged in all the way.

MacBook connected Hitachi CP x301 Icons do not appear


Ok what's happening is that you have it set up as an extension of your desktop, you need to mirror the displays. when your projector is plugged in and it is showing only the desktop background, open "System Preferences," click "Displays," click "Positioning" and check the box that says "Mirror Displays." This should do the trick.

Someone changed a setting


The setting is in the Menu. It sounds like you went to the "Image" section which lets you make the adjustments you list. Try the "Source" menu, then "Mirror". That's where you will find options for Rear Screen Projection, which makes the image backwards.

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.
