5-4. HOW TO IDENTIFY OPTICAL PICK-UP KMS262A/KMS-262E
To check the emission of the laser diode during adjustments, never
view directly from the top as this may lose your eye-sight.
This set uses optical pick-up KMS-262E in the production, but for
the repair, only the KMS-262A is supplied. As a result, two types
of optical pick-ups are used for this set, and the specified values
for the check and adjustment of the laser power vary depending
on the type. Therefore, in performing the check and adjustment of
the laser power, first make sure the type of optical pick-up. The
type of optical pick-up can be identified as follows.
5-3. PRECAUTIONS FOR USE OF OPTICAL PICKUP (KMS-262A/262E)
As the laser diode in the optical pick-up is easily damaged by static
electricity, solder the laser tap of the flexible board when using it.
Before disconnecting the connector, desolder first. Before connecting the connector, be careful not to remove the solder. Also
take adequate measures to prevent damage by static electricity.
Handle the flexible board with care as it breaks easily.

• Check Disc (MD) TDYS-1 (Part No. : 4-963-646-01)
• Test Disk (MDW-74/GA-1) (Part No. : 4-229-747-01)
• Laser power meter LPM-8001 (Part No. : J-2501-046-A)
or
MD Laser power meter 8010S (Part No. : J-2501-145-A)*1
• Oscilloscope (Measure after performing CAL of prove)
• Digital voltmeter
• Thermometer
• Jig for checking BD board waveform
(Part No. : J-2501-149-A)
• Attached software “OpenMG Jukebox”
(Part No. : 4-237-880-01)
• Software for test mode
(Distributed together with the Service Manual)
• Attached USB cable (Part No. : 1-757-471-11)
• Personal computer (Refer to Servicing Notes)
5. When observing several signals on the oscilloscope, etc.,
make sure that VC and ground do not connect inside the oscilloscope.
(VC and ground will become short-circuited)
6. Using the above jig enables the waveform to be checked without the need to solder.
(Refer to Servicing Note on page 8)
7. As the disc used will affect the adjustment results, make sure
that no dusts nor fingerprints are attached to it.
8. In normal operation check after the completion of adjustment,
be sure to perform the recording check (check in, check out)
using the software “OpenMG Jukebox” attached.
*1 Laser power meter
When performing laser power checks and adjustment (electrical
adjustment), use of the new MD laser power meter 8010S (Part
No. : J-2501-145-A) instead of the conventional laser power meter is convenient.
It sharply reduces the time and trouble to set the laser power
meter sensor onto the objective lens of optical pick-up.

5-7-4. Auto Check
This test mode performs CREC and CPLAY automatically for
mainly checking the characteristics of the optical pick-up. To
perform this test mode, the laser power must first be checked.
Perform Auto Check after the laser power check and Iop compare.
Procedure:
1. Click the [ENTER/YES]. If “LDPWR
” is displayed,
it means that the laser power check has not been performed. In
this case, perform the laser power check and Iop compare, and
then repeat from step 1.
2. If a disc is in the mechanical deck, it will be ejected forcibly.
“DISC IN” will be displayed in this case. Load a test disc (MDW74/GA-1) which can be recorded.
3. If a disk is loaded at step 2, the check will start automatically.
4. When “XX CHECK” is displayed, the item corresponding to
XX will be performed.
When “06 CHECK” completes, the disc loaded at step 2 will be
ejected. “DISC IN” will be displayed. Load the check disc (MD)
TDYS-1.
5. When the disc is loaded, the check will automatically be resumed
from “07 CHECK”.
6. After completing to test item “12 check”, check OK or NG will
be displayed. If all items are OK, “CHECK ALL OK” will be
displayed. If any item is NG, it will be displayed as “NG:xxxx”.
When “CHECK ALL OK” is displayed, it means that the optical
pick-up is normal. Check the operations of the other spindle motor,
sled motor, etc.
When displayed as “NG:xxxx”, it means that the optical pick-up
is faulty. In this case, replace the optical pick-up.
