8 Self-Diagnostic Function

TOP PREVIOUS NEXT

Carry out the following procedure after repair works to ensure effee self diagnosis and tilt adjustment. When using the self diagnosis function, confirm that “NO DISC” is being displayed on the display panel and alsothe optical pickup has not been replaced yet. Carry out the self diagnosis in accordance to the guideline and replace the optical pickup when the current value of the laser drive is above 50.

[NOTE] Measure the value once the POWER button is depressed and power is connected before the equipment warm up (within 3 minutes).

•Carry out the following self diagnosis when “NO DISC” is being displayed on the display panel, the equipment does not read the disc or before the replacement of optical pickup.

1.When “NO DISC” is being displayed on the display panel, equipment does not function smoothly, etc.

2.Check the current value of the laser drive. With no disc in the drive, press the “Screen Display” button on the remote control while pressing the STOP button on the equipment.

3.Implement step 4 if the value is below 50. Replace the optical pickup when the value is above 50. After replacement, implement step 2 again and if the value of the optical pickup is above

40, replace the optical pickup again. There is a possiblityof electrostatic failure during replacement.

4.Carry out tilt adjustment of the optical pickup if the value of the optical pickup before replacement is below 50 or the value of the replaced optical pickup is below 40.

5.Carry out initial setting. Press the “> 10” button on the remote control while pressing the STOP button on the equipment. With this, the whole procedure is completed.

When an FROM or an EEPROM in and on the module P.C.B. has replaced, carry out the recovery disc processing to optimize the drive.

Playback the disc above to process the recovery automatically.

Recovery disc (Product number: RFKZD5TR001 [SPC supply] )

FROM disc (Product number: RFKFRV45C040 [SPC supply] )

Note:

This unit requires no initialization process carried out after the traditional DVD players were repaired. When the recovery measures are taken, the customer setting will return to the factory setting as same as the procedure described in item of “Initialization” in10.1 is carried out. Write down the contents of the setting before recovery processing, and reset the player.
