Dell 3200 Projector color green instead of yellow on VGA not on S-Video

This happens when the blue channel of the VGA cable doesn't work. This can be by an internal defect or by a defective cable. Since you changed the cable already, its the connector.

Replacing the lamp module requires special considerations:

1. Turn off the projector.
2. Wait 30 minutes for the projector to cool down and then unplug it.
3. On the bottom of the projector, loosen the two screws on the lamp cover and then remove the cover.
4. Loosen the two screws on the lamp module and pull out the module.
5. Insert the new lamp module and tighten the two screws.
6. Install the cover and tighten the two screws.
7. Turn on the projector. If the lamp does not turn on after the warm-up period, try reinstalling the lamp again.
8. Press enter on the projector or on the remote control to open the on-screen menu.
9. Press the up ( ) or down ( ) arrow to select Setup and then press the right ( ) arrow.
10. Press the up ( ) or down ( ) arrow to select Reset lamp hours and then press enter .

what cable are uusing coumpount vga 15 pin to coumpunt or u try new cables

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)

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.

There are 3 different types of analog video signal ports on your projector; s-video, composite video, and RGB. Which one of the three are you using to connect your PC to?
The projector's resolution rate is XGA [1024 x 768]
If you are using a VGA cable designed and capable of handling 640 x 480 resolution; then it will not support XGAs 1024 x 768 signal. On the other hand, if the coaxial cable you are using is a multi band one that is capable of supporting VGA and XGA resolution signals, most likely the problem is not with the cable- although I have come across brand new cables that are defective.
Please let me know if this helps or else we'll try another approach :)

Replace the connector(s). It's likely the red component has failed...

Unfortunately, there is no simple VGA-to-RCA adapter cable if you're connecting to a composite video input (usually colored yellow) or s-video input. VGA output is separate red, green and blue video and synchronizing signals, and they all need to be combined. You need a VGA-to-video converter to do this.

If the projector has component video input jacks, then you can buy a simple adapter cable.

Hope this helps. Thanks for using Fixya!

I'm going to guess that you are using an RGB cable to connect to the projector and the projector is expecting a composite signal. The composite signal would be what uses a yellow connector when you use hte red/whjite/yellow type of cable. All of the video is carried by the yellow. If the projector is expecting this and you send out component (RBG in this case), then the only video signal processed is the green. Since the green also contains the sync signal, the picture will be seen but green.

Check the menus on the projector. You should find a video selection area that will allow you to change to component input.

Please update this if you have any more questions.

try reseating the vga cable. Try removing the cable, the green tint should disappear meaning that the color or lack of one of the primary colors blue/red/green were missing due to bad connection. or maybe you have a bad vga cable.
