This is a longshot, but if you are restoring your Rv-b90, you likely know how to fix my issue. I had not used the cassette feature for a long time, usually just listen to CD's. Put in a tape, it clicked but would not play. Now, the window shows that it is in play mode (but it isn't playing), and the door will not open. How do you force the door open and remove the cassette? I don't want to damage the tape as it contains our wedding music. Simply wanted to make a playlist from it. Help!
