The TX-DS797 contains an internal microcomputer that performs
high-level operations. However, on extremely rare occasions, noise
or interference from an external source or static electricity may cause
faulty operation. If this occurs, unplug the power cord from the wall
outlet, wait five or more seconds, and then plug it back in. This
should correct the situation.
