Display Of The Error History - Pioneer DVD-V7400 Service Manual

DVD-V7400, DVD-V7300D

7.1.2 Display of the Error History

• The type, date and time, and the number of occurrences of errors
of the player can be recorded.
Up to 8 types of errors can be recorded, and the number of
occurrences can be counted up to 255 per error type.
The date and time of the latest error is recorded per type. The date
and time are based on the real-time clock built into the player.
If the real-time clock has not been set or the setting is wrong, the
dates and times of occurrence recorded will be those of the clock
at that time.
• An example of the error history display is shown below:

• In the above example, two types of errors are recorded, and six
other types of errors can be further recorded. In the above two
cases (error codes "11" and "C3"), the error history will be recorded
until their error count becomes "FF."
• The data of the error history can be cleared if the number of error
types reaches eight or the number of errors reaches 255. After the
data of the error history are cleared, new errors can be recorded.
(Cleared data of the error history cannot be restored. It is
recommended that the data of the error history be written down
before clearing.)

How to display the error history
• Press the ESC, TV/LDP, then SIDE A keys on the remote control
unit for service use, in that order.
How to clear the data of the error history
• While the error history is displayed, press the CLEAR key on the
remote control unit for service use.
Display of power-on and playback duration
• The power-on duration and playback duration of the player can be
recorded.
See below for how to display power-on and playback
duration.
• Power-on duration: Accumulated power-on duration of the player.
• Playback duration: Accumulated playback duration of the player.
Duration is counted even in Pause and Still modes. This playback
duration can be considered to be the spindle motor's duration of
rotation or duration of use of the laser diode.
Note: The power-on duration and playback duration are measured
using the CPU clock of the player, so you should allow for
about 2% error. Use these displays merely as a guide for
servicing.
• The data of the power-on and playback duration are not cleared if
the player's software upgrade is downloaded from the dedicated
web site.
(As for the DVD-V700, the data of the power-on and playback
duration are cleared when the player's software is upgraded.)
How to display power-on and playback duration
• While pressing the DISPLAY key of the main unit, set the POWER
switch to ON. (This is also explained in the Operating Manual.)
