Projector is not able to project red from the vga cable

If i use the vga cable from the computer it will not show reds. (the pop-up menu will show red when the red is adjusted in the menu) But if i use the s-video port, reds are shown crisp and clear! do you think this is a VGA cable problem, or is it a problem inside the projector? i have tried the connections on multiple computers with the same result, but i have not tried to change the cable. ($50---HA!) i would think this projector has only one video card that supports both VGA and s-video ports and therefore if it was an internal problem, it wouldnt work on either!? OH--and the cable pins are ok. Thanks

Re: projector is not able to project red from the vga...

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.

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.

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)

No Reds , replaced VGA cables, interface, projector bulb, still no reds.

One of the pins on the 15 pin VGA cable had been folded over in half. Proved the computer and cabling worked with another projector. Reinvestigated the connections wired into the ceiling to the projector and discovered that the VGA cable in the wireway had been damaged slightly. Bent and straightened the number one pin on the vga cable and everything is fabulous.

Dell 2300mp projector, colors bad

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.

not all computers are F4 - some are F7... - If there is not a small graphic on each Function button - just press and hold your function button and I'd start with F3 then F4 then F5 and so on - often your image will appear on the projection screen and disappear from your laptop - just re press Function and the appropriate key - you may also need to change your display - go to your control panel then display then settings and you will want 1024x768 - as far as cables you will need a male VGA that will plug into (usually blue) connection on your laptop and then depends on what type of projector you are using - it may take a VGA or RGB (5pin cable ~ red green blue horizontal vertical) make sure that in your menu settings that you have it set to the same as the input you have plugged into
