So after 6 months of waiting I got my replacement HDMI board from Marantz. I installed it last night and I initialized it like it said to in the service manual. It worked. I hooked it up and turned it on and after a while of working it freezes up and displays error CY920. I looked this error up in tje manual and it said I need to load the firmware update. I don't see any downloads on the marantz website. Does anyone know where to get it?
