Green screen on VGA with Viewsonic PJD5122

The projector has 3 VGA ports and the problem persists with every port. Multiple VGA cables have been tried, and multiple VGA-out devices, and it's all the same. The projector's demo screen is a colorful image on a white background, and looks fine when the projector boots up.

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.

SOURCE: projector is not able to project red from the vga cable

I assume connecting a monitor/lcd panel display doesn't exhibit the missing red? To narrow this down, try using the cable with either a different projector or monitor/flat panel display. In short, does the problem follow the cable to these other devices? If so, then even though there are no pins bent over, the cable is probably bad. Cables can develop an internal connection break, even without showing any external evidence. This will usually occur at a connector end, and is often the result of overflexing, bending or other straining of the cable near the connector. Can you borrow another cable from a friend? A couple of other possibilities: 1. A broken solder connection at the VGA jack inside the projector. This can occur, again, if the connection is stressed (flexed, jammed, pulled on etc.). 2. The circuitry just beyond the VGA jack, which processes the video information could have a defect, not passing the Red info. The latter problem is one for a capable technician, and depending on expertise, you might be able to repair a broken solder connection.

SOURCE: Bought 3 MP3300 projectors for presentation projects

you can replace the colorwheel yourself, but unfortunately dell does not sell parts. you need to send the projectors in for repair. and like the other guy said, never buy lamps from e-bay.

What cable or adapter do I need to connect my projector to a MacBook video out port?


You will need a Mini-DVI to VGA adapter. Apple sells this item through their online store.
http://store.apple.com/us/product/M9320G/A?mco=MTY3ODQ5OTY
You will also need a male to male VGA cable to attach the adapter to the projector.
You can find modestly priced cables at monoprice or other retailers. example: http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10201&cs_id=1020102&p_id=2898&seq=1&format=2
Plug the cable into your projector and then plug the adapter into your MacBook. The MacBook will automatically resize your picture to the appropriate resolution for the projector.
Enjoy!

I have an Acer One netbook and tried to connect it to a projector but the normal looking lead from the projector did not seem to fit. The lead has those two wee screws at the side, and no place for them...


The Acer One netbook has a mini-VGA port on its left side. Page 10 of Acer's QuickGuide shows the port as item 3 External display (VGA) port. But unfortunately, the description shown for it is incorrect.
From your description, your projector's lead likely has a mini-VGA connector on the end as pictured. The connector can simply be plugged into the mini-VGA port but there are no holes beside the port for screws so it would just be a friction fit which should be sufficiently secure for most puposes. The connector and port are mini-DB 15 male and female respectively and can only fit one-way. The port has the wide side of the D on top so you would have to turn the pictured connector over to be able to plug it into the port. Windows XP should be able to detect the projector via plug-and-play installing any display drivers if required. Page 8 of Acer's UserGuide describes Hotkey + Display toggle which switches display output between the display screen, external monitor (if connected) and both. Pressing + with the projector plugged in will bring up a window in the middle of the screen allowing the selection of internal display, external display, both, or a 800x600 VGA projector. If the display is on the projector, unplugging the cable should automatically revert display back to the internal screen. For VGA see http://en.wikipedia.org/wiki/VGA_connector splines.jpg

The projector shows slides as purple but computer has the right colours?


Check your cable...you are missing one of the primary colors. you could have a bent/broken pin on either the projector port or the cable or laptop port. this would be the VGA connection.

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


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.
