1. SAFETY INFORMATION

WARNING THE AEL(ACCESSIBLE EMISSION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN CLASS 1 BUT THE LASER COMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING THE LIMIT FOR CLASS1. A SPECIALLY INSTRUCTED PERSON SHOULD DO SERVICING OPERATION OF THE APPARATUS.
LASER DIODE CHARACTERISTICS FOR DVD : MAXIMUM OUTPUT POWER : 5 mW WAVELENGTH : 655 nm FOR CD : MAXIMUM OUTPUT POWER : 5mW WAVELENGTH : 785 nm

LABEL CHECK

Printed on the Rear Panel
Additional Laser Caution 1. Inside detection switch (S201 on the SMEB assy) and clampstatus detection switch (S11 on the TRSB assy) are detected by the microprocessor (IC11 in the DVDM assy). To permit the laser diode to oscillate, it is required to set the inside detection switch for the inside position (S201 : ON) and to set the loading-status detection switch for the clamp position (the center terminal of S11 is shorted to +3.3V). The 655 nm laser diode for DVD oscillation will continue if pin 19 of IC1 is shorted to +5V (fault condition) in the DVDM assy. The 785 nm laser diode for CD oscillates if pin 20 of IC1 is shorted to +5V in the DVDM assy. In the test mode , the laser diode oscillates when microprocessor detects a PLAY signal, or when the PLAY key is pressed (S5817 ON in the KEYB assy), with the above requirements satisfied. 2. When the cover is open, close viewing through the objective lens with the naked eye will cause exposure to the laser beam. : Refer to page 74 on service manual RRV2460.
2. CONTRAST OF MISCELLANEOUS PARTS
NOTES: Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List. The mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation. Screws adjacent to mark on product are used for disassembly. Reference Nos. indicate the pages and Nos. in the service manual for the base model. When ordering resistors, first convert resistance values into code form as shown in the following examples. Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%, and K=10%). x 101 RD1/4PU 1 J 561 47k RD1/4PU 3 J 47 x 0.5 RN2H R K RRS1P 1 R 0 K 1R0 Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62k 562 x RN1/4PC F

Description of Error

ID can not read during tracing

Causes if with a DVD

An ID could not be read for 1 second or more.

Causes if with a CD

Operation of the Unit
Subcode check failure during playback ID can not read at 73 the startup 74 Subcode check failure during startup
No frame could be read for 3 seconds or more. An ID could not be read within 1 second after the AFB adjustment had been finished. No subcode could be read within 3 seconds after AFB adjustment had been finished. TOC readout took 30 seconds or more.
Opens (ID readout failure) Opens (Subcode readout failure).
Timeout for reading 81 TOC of the mechanism controller Timeout for reading 82 TOC of the system controller Communication A1 timeout of DSP command A command could not be issued to DSP because Command Busy (XCBUSY) was in force (XCBUSY = L) for a specified time (about 200 mS). Command Busy (XCBUSY) was in force for a specified time (about 200 mS) before and after a coefficient read command was issued to DSP, or the address echo-back after command issuance did not match the setup address. Command Busy (XCBUSY) was in force for a specified time (about 1024 mS) before and after the coefficient write command was issued to DSP. Command Busy (XCBUSY) was in force for 200 mS during continuous coefficient writing, or before and after a continuous write command was issued to DSP.
Reading TOC of the system Stop controller took 30 seconds or more.

No operation

Communication A2 timeout for reading DSP coefficient Communication A3 timeout for writing DSP coefficient Communication A4 timeout for continuously writing DSP coefficient B1 Timeout error for backup Retry error for backup

In the tracing state during the backup sequence, codes could not be read for 1 second or more. In the backup sequence, tracking ON sequence of the servo DSP could not be completed even if more than 500 mS after the tracking ON command was issued. Tracing impossible after retring the tracking ON for 3 times in the backup sequence. During tracing, runaway was detected after three iterations of backup operations for detecting runaway.
Stops Stops Stops (the mechanical controller operates independently). Turns off the power instantly (No indication on the FL display and no writing to flash memory) Stops
B3 Retry error for trace C3
Detection of tracking During playback, the overcurrent detection port was at L for 300 ms or more overcurrent continuously. Short-circuit test corresponding error Violation against digital copy guard While the power was on, the overcurrent detection port was at L for 40 ms or more continuously.

F5 Tray being pushed

The tray switch that had been Open mode was forcibly changed to a mode other than Closes Open by an external force. Reverses the loading Loading, unloading or clamping could not be completed within a specified time (about direction. It timeout is 5 seconds). repeated upon retry, the unit stops. The following error occured eight times. (1) Focus ON sequence could not be completed even if more than two seconds after the focus ON command (to the servo DSP) was sent. (2) Focus IN sequence was finished, actually focus IN was not completed. Stops wherever possible then opens (stops in the case of side B).
