Hello everyone. I have a problem with my Sony MZ-R3. The device powers up, but only displays 'Error 40'. When I press play, it shows 'MO RUN', and 31 or 32 below, depending on weather or not I have inserted a disc. I read the service manual and it said, that I'm in the automatic adjustment mode. The player never went further than '32'. The disc I'm putting in it works as I have tested it in my other players. One time I was using the player and it worked fine, then I put it aside, and when I tried playing it again, it just displayed 'Error 40'. Thank you for help in advance.
