Marantz Pre-Pro Glitch

I have owned a Marantz AV-7005 pre-pro for several years and never had a problem. I recently bought

an AV-7701 off Agon and can't seem to get it to recognize the HDMI input and/or pick up correct codecs.

It has an HDMI input specifically labeled 'Blu-Ray', so that's what I used. For a day or two, I was getting

video, but only Dolby Pro-Logic audio processing. Now it appears to be picking up the newer codecs,

but there is no video through the HDMI. I've tried using another HDMI input, still nothing. Would appreciate

any suggestions anyone who's run into this with the AV-7701 might have. The Blu-Ray player is an Oppo

BDP-95 that is connected to the pre-pro through both the HDMI and 7.1 analog outputs.

Swap HDMI cables out and see if that fixes the problem.

Also, by unplugging the Marantz for 10 minutes and then plugging it back in the system does a reset.  Sometimes that works to fix issues on my Marantz 8801 pre/pro.

Thanks admranger......I have gotten past the HDMI problem, but now I have a situation where the pre-pro is locked onto Zone 2 output mode, limiting all parameters to those that apply specifically to Zone 2. I can't figure out how to 'unlock' Zone 2 output....I tried to use the remote from my AV-7005, which lets me turn zones on/off from the remote. I've gone into the set-up menu and made sure Zone 2 is turned off there, so this has me stumped.

Hmmmm...I got nothing.

Try the reset procedure I described above.  If that doesn't work, try AVS forums.  They have dedicated forums to pretty much every Marantz pre pro

Depending on the vintage, some Marantz AVRs had HDMI sockets that failed over time.  I had to replace my family room Marantz AVR after two years of seeing one socket fail, moving the cable to the next socket, seeing that one fail after several months, etc.

Im not sure how long this problem plagued Marantz, but it wasn't just me.  A web search (many years ago) revealed that the issue was pretty widespread at the time.
