Dell 3200 Projector color green instead of yellow on VGA not on S-Video
I have tried the S-Video port and my yellow is yellow but useing the VGA the Yellow is Green. I have replace the cord, checked it out on other computers and have the same result. Is it the VGA on my Projector? What kind of checks should I make to narrow the problem down? Is it expensive to replace the VGA port or can I install a driver to fix the problem. Or heaven forbid, do I need a Mother Board????
Thanks D. James
Re: Dell 3200 Projector color green instead of yellow on...
I have found that the S-Video port has the correct colors, but the VGA port has green inplace of yellow. I believe the VGA port on the projector is the problem. I don't know how to replace the VGA port or if it can be replaced. Thanks D. James, tweezers.

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 :)
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.
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.
NO , it will definitelly not solve the problem at all.
Usually if there is a discoloration it is either the colourwheel ( turn the Projector upside down and back again - if you hear anything loose falling around on the inside - then your clourwheel is broken) But the unit will switch off almost 98% of the time if the clourwheel was faulty.
Otherwise it is gonna be your Mainboard that needs repair or replacement. Must warn you it is a expensive part to have replaced.
