Hi, I'm having trouble connecting my av receiver and vcr to my optoma hd20 projector. I'm using composite and no signal is being detected by the projector. If i connect a dvd to the projector using composite, a signal is detected and a picture is displayed. My receiver is a marantz sr5200.
any ideas anyone?
 
i found a similar problem when i tested the composite out from scart on an old skybox to the hd20.

it would not work until i connected up and switched on the red and white sound outputs to a receiver. maybe that may work for you aswell.
 
Thanks, I didnt think it would work, but i tried it anyway. And... it worked!!! Connecting the audio and the video to the receiver worked!!
Thanks
