Hi,

I'm introducing an HD621 into a system with a G65 and a Panasonic Plasma TV (TH50PZ850U). Connection to G65 is via MMHR and comm. I get sound but no picture. I think it is a handshake issue but when I've seen that problem before there is some flickering of the screen before it goes black. In this case I see nothing at all on the screen. The sources are TIVO and Oppo. This set up was working with a simple HDMI switch so I know (or think) the cables are not the problem.

I tested the HD621 with a different Panasonic Plasma (newer) in another room and it worked. For the test, I ran an Oppo into the HD621 and then connected the HD621 out directly to the plasma. So the HD621 was not connected to a processor.

I tried the same "stand-alone" test with the plasma where I want to install the HD621 and it did not pass video. So it seems there is some sort of problem between the HD621 and this particular plasma.

My dealer suggested that I try a different HDMI input on the TV which I have not done because the TV is mounted on the wall and the inputs are not reachable without taking the damn thing off the wall. Will do if there is no other option.

I wonder if I had a video processor or some other device in the chain between the HD621 and the TV would the problem still arise. In other words, does the device only need to handshake with the units immediately before and after? I think it probably has to do a proper handshake with every device in the chain. At one point I had a Radiance before this TV (but no HD621) and had no problems which is why I was thinking of sorting this by putting the HD621 out of direct connection with the TV.

Anyone had or heard of a problem like this?

Suggestions?

Thanks.
