5.1 Self-diagnosis function and service mode

TOP PREVIOUS NEXT

Each results of self-diagnosis function and service mode is displayed on the LCD of AV control receiver (SA-DT100). When using these function, confirm the unit to be connected by system cable.

Improving the self-diagnosis function

The self-diagnosis function in our DVD player currently in use is improved as follow:

Pressing various button combinations on the player and remote control unit can activate the service modes.

Item Player mode and

button combination

Jitter check In PLAY mode,

press “STOP” button on the player and “5” button on the remote control unit.

Error code check Press “STOP”

button on the player and “0” button on the remote control unit.

Function Display Cancellation

Jitter check Jitter rate is measured and displayed. Measurement is repeatedly done in the cycle of one second. Read error counter starts from zero upon mode setting. When target block data failed to be readout, the counter advances by one increment. When the failure is caused by minor error, it may be corrected when retried to enable successful reading. In this case, the counter advances by one. When the error persists even after retry, the counter may jumpby two or more.

Error code check The latest error code stored in EEPROM is displayed.

J*1_xxx*2_yyy*3_zz*4 *1: Jitter check display mode *2: Jitter rate *3: Readerror counter *4: Focus drive value Jitter rate is shown in decimal notation to one place of decimal. Focus drive value is shown in hexadecimal notation.

Error code (play_err) is expressed in the following convention. Error code=0xDAXX is expressed→DVD nn UXX Error code=0xDBXX is expressed→DVD nn HXX Error code=0xDXXXis expressed→DVD nn FXXX Error code=0x0000 is expressed→ DVD nn F--Error code except above→DVD nn XXXX *nn denotes the serial number of history.

ADSC internal RAM data check

In STOP mode, press “STOP” button on the player and “PAUSE” button on the remote control unit.

In STOP mode, press “STOP” button on the player and “OSD” button on the remote control unit.

Press “STOP” button on the player and “1” or “2” buttons on the remote control unit.

Initial setting of laser drive current Initial current value for each of DVD and CD laser is separately saved in EEPROM.

DVD laser drive current measurement DVD laser drive current is measured and the result is displayed together with the initial value stored in EEPROM. After the measurement, DVD laser emission is kept on. Itis turned off when Standby/on key is switched off. (It is also turned off when the primary power is switched off.)

ADSC internal RAM data check ADSC internal RAM data is read out and displayed. Change the address with “CANCEL” key operation to show the data for 11 addresses.

LD0*1_034*2_028*3 *1: Laser current measurement mode *2: DVD laser current measurement *3:CD laser current measurement The value denotes the current in decimal notation. The above example shows the initial current is 34 mA and 28 mA for DVD and CD laser.

LDD*1_034*2_032*3 *1: DVD laser current measurement mode *2: Initial current stored in EEPROM *3:Measured current The value denotes the current in decimal notation. The above example shows the initial current is 34 mA and the measured value is 32 mA.

A*1_0FA*2_6901*3 *1: ADSC internal RAM data check mode *2: Address *3: RAM data for specifiedaddress The value is shown in hexadecimal notation. The above example shows the data in ADSC address 0FAh is 6901h.

Press “STOP” button.

CD laser drive current measurement

In STOP mode, press “STOP” button on the player and “3” button on the remote control unit.

CD laser drive current measurement CD laser drive current is measured and the result is displayed together with the initial value stored in EEPROM. After the measurement, CD laser emission is kept on. It isturned off when Standby/on key is switched off. (It is also turned off when the primary power is switched off.)

LDC*1_028*2_026*3 *1: CD laser current measurement mode *2: Initial current stored in EEPROM *3:Measured current The value denotes the current in decimal notation. The above example shows the initial current is 28 mA and the measured value is 26 mA.
