Unfortunately, there are a number of possible causes: power supply going
out of regulation; reset needing to be recalibrated; dead latch ICs on
the CPU board; etc.
Is this one of the units that had battery-leak damage in the past? Even
when repaired, these units can develop troubles later on, due to hidden
damage to the board traces & continuing decay from traces of acid that
weren't cleaned up.
