hooking old school nintendo to projector

[boodroe]

I am trying to connect my original Nintendo to my projector through an Onkyo TX-SR803 AV Receiver on the RCA composite port. The reciever upgrades the signal to component that connects to the projector. Once I turn the nintendo on I dont get any color, just black and white. The game runs as expected except the picture is in black and white with scan lines. The nintendo works perfect on the other TV. A VCR works perfect hooked up the same way on the projector. Iv tried switching cables and end up with the same results. Oh, and the same thing happens when I hook up my SEGA GENESIS. Are these two consoles too old? Can you not upgrade the signal of these consoles to component? It seems that if it works with the VCR it would work with these consoles. Any suggestions on what is going on and how to fix it. Thanks!

I've experienced that with my HK receiver... it doesn't like the Genesis or the NES.  You'll have to hook them up directly to the monitor.

You may want to try connecting it through the VCR.  I am not sure if the Nintendo sends color burst or not.   

Also, with Sega Genesis, you may want to go to the GamesX.com site and try connecting it through RGB, possibly with a scan converter if the projector does not accept 15Khz.
