My SR7300 has a similar problem. It works fine apart from no display. I tracked to problem to open circuit filaments (heater elements) in the fluorescent display. Could be a tough ask getting one of those displays these days.
Hi @ratbaggy , For what it’s worth the display is a Noritake CM2071C. Marantz part # HQ31606920 Part ID is VC01, found on p.50 of the service manual. I couldn’t find it by searching for the part number or the make and model number. You may have better luck.
