6-2-10. ATA/ATAPI Debugging Screen (Second Screen) and LD Deterioration Judgment (for writer)
1. Writer maintenance information of ATA/ATAPI DEBUG OSD (Subscreen3)
1) Turn of the main power ON.
2) On the screen after exiting all menu screens, press “ESC” on the service remote controller.
3) Press “DISP”.
4) Press “2”.
Update the display by pressing the “SEARCH” key while subscreen 3 is displayed.

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.
[Tips]
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 lighti
ng
time data.
5) Press “ESC”. (Returns to the original screen)
* Simplified judgment method of optical pickup quality
1. Stains on pickup lens
2. Deterioration of CD-R/DVD-RW laser diode
* Screens are switched when “DIG/ANA” is pressed two times or
three times to select the desired menu. Press “SEARCH” to start
measurement.
