WOW another person that kept the rd-kx50, Welcome brother or sister to the fold..lol.

I had that problem a couple of times, I just remove the hdmi cable while the tv and recorder are off, and then connect it once it's back on.
It's a pain to do this, but you could just use the component cables and not worry about the issue (at a slight cost of picture quality)

try replaced z board Manufacturer Toshiba Part Number 75003032 Description ZSUS PCB ASSY

try switching to a different video source and play a DVD or a game system. If the issue is still there try unplugging the TV for 5 min. and then plug it back in.If the problem works fine on all other devices except the video source that has the issue try hooking up the same device your having the issue with to a video source you know works if that works then you have a bad video source on the back of the TV, if it does not work it's either the cable going to the TV or the device itself.

It sounds like the HDMI port on the back of your Marantz is damaged. if you know for sure that the HDMI port works on another tv still you might just use component connection because the visible difference between component and HDMI is not very recognizable.

Try this

1. Turn ON TV
2. Connect PS3 to TV HDMI input
3. select TV HDMI input for PS3
4. turn OFF PS3 if it is ON
5. Press and hold the [I/O]Power button until the PS3 until you get the "HDMI Detected" message.

Also, this TV has a circuit that deactivates the HDMI if the rear cover is removed. It is possible the HDMI may have been turned OFF. This is reset in the service menu of the TV.

Same thing happens to me, turn the tv off and back on, it will work fine then.

I talked to Toshiba about his problem, this morning. They said they have never hear of such an issue. I told them the TV was less than 1 week old, and would hope Toshiba would do something in response to my alternative action of returning both my Toshiba HD DVD and 52LX177 for a new brand. They said all they can do is have me go to a service center for them to repair it. 1 week old TV and DVD, $4000, for repair; I don't think so. I talked to two different people a Toshiba regarding this, with the same answer. Very poor customer support, especially for a higher end product like this. I think I have no choice but to change brands.
