Onkyo 606 No video through HDMI, Audio is there though.

[stfn]

Hello,

Just hooked up my first Receiver after having to wait 4 months for my 5.1 set.

I tried my PS3 and I hear the audio, but no video at all just snow. I replugged the HDMI cable in and 1 time it worked and I had video for a few minutes. But when I switched to a different HDMI source and back to this one again, video was gone again.

I really have no idea what the problem here is. I hope someone here does.
