2.2.3. Optical Pickup Breakdown Diagnosis
This unit is equipped with the optical pickup self-diagnosis function and the tilt adjustment check
function. Follow the procedure described below during repair in order to perform self-diagnosis and tilt
adjustment effectively. Especially when “NO DISC” is displayed, be sure to apply the self-diagnosis
function before replacing with an optical pickup. Replacement of optical pickup generally requires when
the present value of laser drive exceeds 45 (DVD) or 45 (CD).
Note:
Start diagnosis within three minutes after turning on the power (as diagnosis fails when the unit
becomes warm).

2.3.1. EEPROM Checksum (ROM Correction)
Purpose: To check for microprocessor firmware version and EEPROM checksum (ROM correction).
Below are the procedures for this mode.
Step 1: Enter into Doctor mode (for more information, refer to section 10.3 on key operation to enter into
this mode.
Step 2: Check for firmware version and EEPROM checksum (By pressing STOP button on main unit
17

followed by “4” and “7” on remote control).
- When entering into DOCTOR MODE, the firmware version and
checksum of EEPROM (if applicable) will appear on FL display. Below
is the information on the EEPROM IC (ROM correction) under 3
possible situations:
1. In the case that the correction point existence data is other than 0 (ie.
correction file exists), EEPROM checksum display for the
microprocessor shall be made after calculating checksum by summing
up the content of data area from EEPROM.
2. In the case that the correction point existence data is 0, [NO] shall be
displated.
3. In cases that the filename is different even though a EEPROM is set,
or no correction file exists, [NG] shall be displayed (the correction point
existence data is set to 0 at this condition).
18

Note: Microprocessor firmware refers to version number for microprocessor IC. It is subject to change
which would be updated accordingly. ROM correction checksum refers to the HEX code that is
displayed upon key buttons pressed if an EEPROM is loaded in the unit.
