To be used as a rough guide to judge
whether the pickup unit is all right or not
• Dirt on the pickup lens
• Degradation of the laser diodes for
reading CDs and reading/writing to/from
DVDs
• While the User Operation display is displayed, press the ESC , DISP , then 2 keys, in that order.
• While any subscreen of the second screen is displayed, press the DIG/ANA key repeatedly.
The subscreens change cyclically.

If the total hours of duration of emission of the laser diode (LD) for DVDs while reading
2
and that of
emission of the LD for DVDs while writing
3
exceed 4,700 hours, the LDs may be degraded.
Perform an LD degradation judgment, using subscreen 4.
Press the ESC key.
Press the ESC key.
• While the User Operation screen is displayed, press the ESC , DISP then 2 keys, then the DIG/ANA
key twice, in that order.
(1) Writer maintenance information of ATA/ATAPI DEBUG OSD (Subscreen 3)
MTTF hours for each LD
DVD: 4,700 hours
CD: 11,000 hours
The ATA/ATAPI Writer Maintenance Info is obtained each time the power is turned on. Thereafter, the
data on the subscreen is updated each time the SEARCH key is pressed (the updating command is
sent) while this subscreen is displayed. Care must be taken when updating this subscreen, because an
undesired command is inserted if it is executed while recording, etc.
[Note on lighting time data for each LD]
Since data on lighting time of each laser diode (LD) are stored in the flash ROM on the MAIN Assy, after
the MAIN Assy is replaced, the data will be cleared. However, after the LOADER Assy is replaced, data
on lighting time of each LD will be retained in the MAIN Assy. Therefore, before either the MAIN Assy or
LOADER Assy is to be replaced, it is recommended that you write down the lighting time data.
