Sharp Notevision PG-C30XE problem with computer display


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 :)

Green uhe on white


green discolouring in white means lack of red.
probably wrong input setting or signal interruption on input- or mainboard. Check mainboard for smd capicitors with losses in value.

My Epson EMP-S1 projector shows pink color with VGA input only, ok with video input and menu screen. What can be the problem?


With the VGA you have a bad cable or a bad input jack. I would bet on the cable first. You are missing the green or the blue on the screen and that is why the red/pink is more pronounced now.

When i connect the projector to my computer, all it says is no input selected. i need help with this IMMEDIATELY!!!


make sure the computer has the output screen signal enabled on the external rgb connector. you can confirm this by connecting an external lcd monitor to the pc. swap the pc vga output to the projector.
then make sure the vga/rgb input source is selected on the projector.
also select the lowest resolution on the pc to start with. when a picture appears on the projector, then increase the pc screen resolution until it says it's not able to show it, and back off to the last setting that worked

Our club owns a Canon LV-7240 which has worked OK. Last night we showed an NTSC DVD from Europe and no red showed. We could see what the colours ought to be on the laptop screen. On the big screen,...


Can't answer for the menu issues, but I can garuntee this is not a problem with brightness, contrast or sharpness, and very unlikely that you'll find a solution in the menu. What is likely is that the VGA wasn't plugged in properly initially. When the signal is going down the VGA it's broken up into 5 seperate signals, Red, Green, Blue and 2 sync signals. What is likely is that the green and blue pins havn't properly made contact either inside the projector or inside the laptop. This would also explain why it worked when you tried later because it made the connection properly. I would suggest trying again with the same laptop, if it does it again, try another PC without moving the projector or the VGA connector that's plugged into the projector. This will atleast narrow down your problem, but it doesn't sound like a problem with the projector to me. Also try plugging the laptop that wasn't working properly into a monitor (this will test the laptop)

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.

Why does my projection look green if the colors are right on the computer?


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.

Connecting Projector to High Def Source (e.g. PS3 HDMI)


That projector supports M1-D also which is the digital side of the M1-DA... Anyway, they sell cables that are M1-D to HDMI to which you can hook directly to the PS3. They are decently priced too, less than $20. I know this thread is old, but I came across it due to an issue I am having with my xb31, broken color wheel. Trying to find parts...
