I had this problem with a Mitsubishi and it turned out to be the cable.

The image color on projection is not the same as shown in laptop. There's is no red color.


It could be a broken connection in the computer lead for the red signal, or a fault on the projector that the red panel doesn't work any more.

To diagnose, bring up the projector's on screen display. If there's white in the menus then the problem is the cable. Replace it with a new one. If the menus are affected too then it's a projector problem. This requires the attention of a service engionner.

My dell 1201 projectors displays only in yellow


you have most likely lost 2 of your color guns, most projectors have RED, Green and BLUE as the projector colors (some newer projectors have added a 4th color). if one of your color guns has gone out, you may experience colors that are not correct. that is where I would start. go to the convergence routine, in your setup menu. this is where you can determine if one of your "guns" has quit working.

Hi there, my dell projector 1800mp is not projecting an image on screen and it only black lines across. what should I do to fix it?.


After turning on the projector, press "+" and "-" buttons on the control panel

simultaneously for 3 seconds and release the buttons when screen goes blank.

2 Press "+" and "-" buttons again to exit the diagnostic mode.

3While in Self-diagnostic mode, the screen will run a seven-color-cycle test as

following:

Red--> Green--> Blue--> White--> Watchet Blue--> Dark Green--> Yellow.

Ensure that the colors of the test pattern are correct. Contact Dell if the colors are
not displayed correctly.

Yellow tint


Hello. Here's the visual key to remember about projectors--LCD panels show their colors like this: RED lcd panel displays cyan onscreen(baby blue); GREEN lcd displays purple; BLUE lcd displays yellow. ( You now know where the displayed dust is!) The problem is most likely a burned blue lcd or polarizer filter in front of the blue lcd panel. This occurs when the dust filter isn't cleaned regularly or properly and heat builds up--yes, enough to "cook" the lcd panel or actually cause a burn to develop on the polarizer. The polarizer is just like a lens in a pair of good sunglasses. It is a small, extremely thin, pane of glass with polarizer material glued onto one side. When burned, it causes a "shadow" effect--that enhances the display of that particular color--in this case, yellow.--Hope I was of assistance!---Rick

No way to get simultaneoulsy my videos on the laptop monitor and on tne projector PLC XU 73 card : ATI Radeon X700


Most laptops have a Function (Fn) key in an alternate color (blue maybe) from the usual key text color (white usually).

By pressing this key, along with another key that has text of the same (blue) color, perhaps labelled with "LCD/CRT" or a pic of a monitor, or of 2 squares - one single square and one double "square in square", you can toggle between the modes of:
1. Laptop display only,
2. external display only, or
3. Both displays.

Be sure to check your laptop model manual for specific details to make sure this is possible.

Depending on what it is if it looke like a scorch mark the it is not the Optical Engine (prism) it is more likely to be the polerising filter most are quite esly changed and would cost about £15 ($30) for parts and about twice that to get them fitted at a service center, if it is pixel dots then it is a LCD replacement and not worth doing.

Colors are distorting e.g. Blue streak across top of viewing field


unfortunately not. the discoloration is caused by the light filter getting fried due to excessive dust and heat. and you cannot purchase the parts individually. you'll have to replace the entire optical engine.

A blue hue


If color correcting does not fix the problem you will probably need some professional equipment in order to fix it. It would probably be best to contact a professional service provider.
