Morning all, I've had my MZ-NH900 for a year and a half. I'm now having problems with the main unit where the buttons and display don't work. I can use the remote to do everything with it, but would like to get the main unit working again. I have all the functionality ie. it plays, records, charges still but am thinkin it is a ribbon cable that needs to be reconnected. Does anyone know which of the 2 ribbon cables would cause this problem? JK
