Tim, optical cables in current technology are for audio only so they have no bearing in a discussion of video.
How is your video connected? Specific details about affected source(s) and their precise connections will help lead to a specific answer.
If you're using component video (Red/Green/Blue) cables you may have them crossed or one is not connected tight. As you state, direct connection is good. I avoid many problems by never running any signal to or through a device that doesn't use or improve it. IOW, video goes straight from a source to the monitor. High-end audio goes directly from its root source to the AVR. No problemos.
Hiya David
Cheers forth reply. We're connected via hdmi. I am worried that the hdmi board has gone. It's just out of warranty too! Arg! Tried different cables... Expensive bit of kit looks like it's gonna get more expensive!
Like I said, you're not absolutely required to have any video run through the receiver on its way to a TV. It's not like the receiver does anything TO the video besides screw it up in your case. Bypass it. That's why all modern A/V sources have separate audio and video outputs. Each should go directly to the device that is designed to extract the best presentation. Unnecessary interconnections only add potential points of failure.
Do you know David, I had never thought of it that way but it does make total sense. I think in my haste last year I just wanted it up and running but there is a separate optical I can use for theps3 so I shall do that! Nice one mate, and thank you for the solution. Not worrying about the repair so much now.
