when problem occur while cam is operating, the self-diagnosis function starts working, and may display the service mode display code. in your case, C:31:40, pertains to a part of the cam tape compartment mechanism called the drum that doesn't start up. issues could prevent you from recording, playing back tapes, rewinding or fas forwarding. t/s steps are: try diff tapes esp. w/prev recordings, reset cam (press reset button while cam is on, located just below the menu button, in the panel where the lcd screen goes to), power reset (remove batt and ac adapter and leave cam w/ any power source for at least a minute). if issue persists, unit will require repair. hope this helps.tnx:)

A bizarre coincidence but our Sony DVD player DAV C700 did exactly the same when the kids were watching a DVD. All other functions on the system are still working but the DVD player wll not eject or play - and the self diagnosis function C 81 remains illuminated on the display.
