Yes, I tried connecting it to tv(sony bravia) in my living room and it works fine.
OK.
Well, then I think the next thing that I would do would be to connect it directly to the PJ to be sure that works too.
If that works, then we are back to a handshake problem as a real possibility, and that can absolutely be one of the most frustrating problems of them all! May not be a good solution if that is the problem.
It may be worth checking the setup on the Marantz to see if it may be trying to do some video processing that is causing the issue. I guess that you are not getting audio at all either? Or can't get far enough along to test that? If no audio and no video, then that indeed suggests it may be handshake. If you get audio but no video, that suggests a config problem.
A workaround may be to use an HDMI to VGA adapter and plug VGA directly into the PJ. Those will also usually have a DAC for the audio stream, and I found that to be better than the onboard DAC on the Pi too. Note--You have to change some config files for the timing etc on the Pi to work with a VGA adapter (search Youtube).
Honestly, I think that you are better off posting in forums dedicated to the RPi rather than the AV forums.
But, if you get this worked out, please come back and post here for the resolution to the problem!
I have a Pi running Emulation Station on my DIY arcarde cabinet. I'm about to set up a Kodi streamer for my BR. Those are the B+ model. Then, I was thinking about picking up a Pi3 to set up a Emulation Station and Media streamer for the man cave.
