optoma hd20 no video signal


Standard Member
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!!
