Sharp Notevision PG-C30XE problem with computer display

I tried with 3 different computers (Asus, Medion, Toshiba with Win7 and Win8) and 2 different vga-cables connecting the projector with the computer. Every time the display lacks the green color. The display shows only magenta and red but no yellow and green. I connected the projector in both of the inputs. The Video input of the projector however is working perfectly, full color, no problem.

    From the Sharp company in Holland I just got the suggestion that "the VGA input was set on YPrPb instead of RGB". So I looked in the menu of the projector and with the first entry "Picture" where you adjust the different colors there was a setting at the bottom of the list: "signal type" - and then a choice: "Computer/RGB" or "Component". It appeared to be set on 'Component' instead of 'Computer/RGB' It was difficult to see the difference. So I put it back to 'Computer/RGB' and the problem then was solved! Bright colors again! The previous setting on "Component" does not make sense to me at all because I always use this projector with a computer (in the RGB mode) and I am the only one who is operating this projector. But OK, problem is solved! Thank you for the replies!

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 :)

Testimonial: "Thank you for the detailed answer! I'll clarify what I did: I connected the Notevision via input1 and later via input2. Both are apparently designed for the computer ('computer'is being printed on the back of the projector at these inputs) The s-video or the RS232C input I didn't use yet. The input3, the audio-video input, I connected with a DVD player (3 cables with tulip- or sony connectors for left-audio, right-audio and video) and that works excellent! The computer cables I use have connectors with 3 rows of 5 pins (total 15 pins) at both ends. I have been able to connect XGA monitors (1024 x 768) through these cables with my Asus and Toshiba computers, no problem there. So I still don't understand why the display is purple-red. Is some circuitry damaged? Could I use Input 3 for the computer? (after transformed the signal from RGB to ... But perhaps (hopefully) the solution is in a different direction."

    Hein, I have a complete copy of your projector's operation manual open in front of me. Let's take it 1-step at a time. You have an Asus computer that you hook up to your projector. 1.) What type of video cable are you using? 2.) What input port are you using for this hook-up? 3.) Does it work properly?

    Thank you John for your efforts! And for the start to systematically solve the problem. I was happy with the answer from the Sharp Holland company, although they were mentioning the YPrPb mode, which I didn't understand. I went to search in the menus and found at the bottom of Picture settings a menu item Signal Type. There it appeared there was a choice between Component and RGB. And indeed the menu has shifted towards Component and as soon as I put it back to RGB the display was bright and colored and sharp! Thank you again for youir assistance

Why is my Sharp PG-D2510X Projector keep saying that there is no signal? It worked up until yesterday.


Check both input selections on your computer and your projector. They both need to be set on the same input to work. For example, if the computer is set at 1080 and the projector is set on 720, it wont work. They need to match. Good luck!
