Problem with eyeclops video projector...after

Unplug all rca cables from your eyeclops, then try all three colors one at a time, into the yellow colored hole on the side of your eyeclops, until you get a picture, and you have to have the dvd player on and playing a dvd, otherwise the light won't come on your projector, then plug in the audio sources, the yellow and white. When I got my eyeclops mini projector, it wouldn't work at all when I plugged the yellow rca cable in the yellow hole on the side of the eyeclops, the red into the red, and the white into white. Only when I placed the red rca cable into the yellow hole on the eyeclops, the yellow into the red hole, and the white rca cable into the white hole did it finally work. That was for my dvd player. With the video game function, I plugged each color Rca cable into their same colored holes on the eyeclops and it worked fine, but again, you have to have your device, whether it be a dvd player or game system on and running before your eyeclops led lights will turn on. Not sure I had to switch colors when I played my dvd player, but that's how it works on my mini projector, anyways.

My sound is not working and i know it has a built in speaker and it has a volume scroll can someone help me
