4.5. SELF-DIAGNOSIS FUNCTION AND TROUBLESHOOTING
Restriction:
The information included in this section is exclusively for service personnel. Do not disclose it to
persons other than service engineers.
The VDR-M70/M50 is equipped with a self-diagnosis function: If it detects a problem when
power is turned on or during operation, it will display a message, replace the content of problem
with an error code (4-digit alphanumeric characters), and then store it in flash memory.
4.5.1. Message displayed by self-diagnosis function
There are two types of message displayed when the self-diagnosis function detects problems:
messages for minor problems, and messages for serious problems.
Information:
The messages of self-diagnosis function will be displayed until the power switch is set to "POWER
OFF" or the disc is removed, regardless of whether there is a minor or serious problem.
(1) Messages for minor problems
These messages appear when troubleshooting is likely
possible for the problem detected when power was turned
on, following the procedure below.
Procedure when message shown in Fig. 4-5-1 appears:
Set the power switch to "POWER OFF", reconnect the AC
adapter/charger or battery, and then set the power
switch to "VIDEO" or "PHOTO (disc)".
Procedure when message shown in Fig. 4-5-2 appears:
Set the power switch to "POWER OFF", press the DISC
EJECT button, and then reinsert the disc. After that, set
the power switch to "VIDEO" or "PHOTO (disc)".
If the problem is handled by the procedure shown above,
servicing is not necessary in almost all cases. However, if
the VDR-M70/M50 cannot be restored from the problem
or the same problem recurs, appropriate servicing will be
required.
The information on minor problems will be stored in flash
memory as error codes (4-digit alphanumeric characters),
whether or not the VDR-M70/M50 is restored from
the problems. See "4-5-2 Error codes stored in flash
memory" for how to display the stored error codes.
