EP739 Projector will not recognize any input signals. Problem seems to have started when it was connected incorrectly to DVD using VGA input with component cable. I believe green and blue were confused. Projector runs through its usual input signal scroll after startup, but no longer (where it once did) recognizes any signal grom VGA or RCA video in. I once used the item as a computer monitor, to display cable TV, DVDs... but no longer. Any ideas on how to solve this one? Any help would be greatly appreciated. Thanks.

You don't say whether or not the "adapter" is simply a gender-changer, or if it actually converts the digital signal from the HDMI port to an analog one for the VGA port. Some monitors have both analog and digital input capability and can automatically adapt to the the digital signal, even if applied to the VGA (analog) port. Other devices are not so smart and need an actual digital-to-analog converter style adapter.
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!
You may need to check the settings of your mac book that permits you to output the signal to an external display. Also you may need to purchase a display port adapter (VGA, HDMI or DVI) that is compatible with the input connector on the projector
Composite video are yellow RCA jacks and are made for analog signals of standard definition video. If you are connecting a digital source or a high definition output, it may be beyond the capabilities of the projector. You may be able to find a VGA to composite adapter if you laptop or whatever has a VGA output port. VGA is along the same lines of composite (analog, standard definition).
I think, the issue might be because of lenght of the composite cable. Not all projectors can "recognize the signal" on too long composite cables, try a "standard size" cable used on monitors, it is i THINK 1,8 feet long...? Dunno. Try two short cables and see if you get "green" - if not, then your cable is too long and gives the signal to much "resistance", so your projector can "read" only one of the color channels, in your case green. If your projector setup requires long cables (and it usually does ;) ), you will have to stick to Cinch connectors and analog video signal, which I have tested on 35m long cable without any visible quality loss. Hope this helps. ;)
