SERVICE NOTES
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic
breakdown because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic breakdown and also use
the procedure in the printed matter which is included in the repair
parts.
The flexible board is easily damaged and should be handled with
care.
• US, Canadian model
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.
If the optical pick-up block is defective, please replace the whole
optical pick-up block.
Never turn the semi-fixed resistor located at the side of optical
pick-up block.
optical pick-up bloc
semi-fixed resistor
• AEP, UK model
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused on
the disc reflective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.
Notes on Chip Component Replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
TEST DISCS
This set can playback CD-R and CD-ROM discs. The following
test discs should be used to check the capability:
CD-R test disc TCD-R082LMT (Part No. J-2502-063-1)
CD-RW test disc TCD-W082L (Part No. J-2502-063-2)

Notes on CD-Rs (recordable CDs)/CD-RWs (rewritable
CDs)
This unit can play the following discs:
Type of discs Label on the disc
Audio CD
MP3 files
• Some CD-Rs/CD-RWs (depending on the equipment used for
its recording or the condition of the disc) may not play on this
unit.
• You cannot play a CD-R/CD-RW that is not finalized∗.
• You can play MP3 files recorded on CD-ROMs, CD-Rs, and
CD-RWs.
• A CD-R/CD-RW to which a session can be added can be played.
∗ A process necessary for a recorded CD-R/CD-RW disc to be
played on the audio CD player.
EXTENSION CABLE AND SERVICE POSITION
When repairing or servicing this set, connect the jig (extension cable)
as shown below.
• Connect the MAIN board (CN402) and the SERV O board (CN1)
with the extension cable (Part No. J-2502-062-1).
NOTE FOR THE OPENING OF THE FRONT PANEL
In this set, the front panel is lowered to below the bottom face when
it is opened.
When servicing the set, place it on a stand having a height of about
2 cm.
stand
FORCED FRONT PANEL OPEN/CLOSE
The front panel is forced to OPEN/CLOSE at the timing that the
power (ACC) is turned off.
If the Z button for the front panel is not effective, the following
method is used:
With the front panel open: The front panel is closed when A CC is
switched from ON to OFF edge.
With the front panel closed:The front panel is opened when ACC
is switched from ON to OFF edge.
NOTE FOR REPLACEMENT OF THE DIGITAL BOARD
When repairing, the complete DIGITAL board should be replaced
since any parts in the DIGITAL board cannot be repaired.
