Thanks for reading. I am new and have an Optoma Projector. When I first connected it I didnt connect one of the RGB cables so the colors were really bad. I fixed it and was in HD bliss. I started it yesterday and thought the cable had come lose as the color was bad again. Then I realized it was the startup screen: Normally a rich blue, now it is grey. So the problem must be coming from the projector. I turned it on and off and did a reset but no luck. There are only a few hundred hours on the lamp. I bought it used, so is it possible that it was patched or quick fixed for the sale? It was a great picture but it seems like repair vs. replace, i would have to go with replace. Ideas? Which budget projector has the largest picture for the least distance? I dont know how to phrase it with throw distance, sorry. Thanks.

Can I use normal RCA cables for composite video + audio (just those yellow/white/red ones) to carry a component video signal a very short distance (just from a DVD player to a receiver, <3 ft)? How much will the signal quality realistically suffer? Thanks!
