1. SERVICE PRECAUTIONS- Service PrecautionsA
B
1) You should conform to the regulations governing the product
(safety, radio and noise, and other regulations), and should keep
the safety during servicing by following the safety instructions
described in this manual. 2) Be careful in handling ICs. Some ICs
such as MOS type are so fragile that they can be damaged by
electrostatic induction. 3) Before disassembling the unit, be sure
to turn off the power. Unplugging and plugging the connectors
during power-on mode may damage the ICs inside the unit. 4)To
protect the pickup unit from electrostatic discharge during
servicing, take an appropriate treatment (shorting-solder) by
referring to "the DISASSEMBLY" . 5) After replacing the pickup
unit, be sure to skew adjustment. 6)During disassembly, be sure to
turn the power off since an internal IC might be destroyed when a
connector is plugged or unplugged. 7) In case the internal fuse has
blown, check the voltage of the rear stage. 8) Handling
instructions for touch panel Please handle the touch panel with
care as it contains glass. Dropping or giving a strong shock may
break the panel. Wear gloves, etc. to protect your hands from the
glass edges that are not deburred. 9) Remove a small board (2
screws) provided for pulling out an RCA line, before removing the
mother board. 10) Hot areas Red area: Hot area. Be careful not to
burn yourself Moter Unit(Side A) Moter Unit(Side B)

NOTES ON SOLDERINGFor environmental protection, lead-free solder
is used on the printed circuit boards mounted in this unit. Be sure
to use lead-free solder and a soldering iron that can meet
specifications for use with lead-free solders for repairs
accompanied by reworking of soldering. Compared with conventional
eutectic solders, lead-free solders have higher melting points, by
approximately 40 C. Therefore, for lead-free soldering, the tip
temperature of a soldering iron must be set to around 373 C in
general, although the temperature depends on the heat capacity of
the PC board on which reworking is required and the weight of the
tip of the soldering iron. Compared with eutectic solders,
lead-free solders have higher bond strengths but slower wetting
times and higher melting temperatures (hard to melt/easy to
harden). The following lead-free solders are available as service
parts: Parts numbers of lead-free solder: GYP1006 1.0 in dia.
GYP1007 0.6 in dia. GYP1008 0.3 in dia.A

Check 12:How to judge whether the flash memory has reached its
life or not.A
If the reaction to user operation is slow or operation is slow
in general, there is a possibility that the flash memory has
reached its life. Make judgment regarding the flash memory life by
looking at the display of the LD energizing time. 1.Let the LD
energizing time displayed. (Refer to the FE test mode for the
method of displaying the LD energizing time.) 2.If the second digit
from the left of the energizing time display is showing E, such as
E , it means that the flash memory has reached its life.

8. EACH SETTING AND ADJUSTMENT8.1 DVD ADJUSTMENTA
1) Precautions This product uses 5 V and 3.3 V as standard
voltages. The electrical potential that is the reference for
signals, is not GND, but VREF (approximately 2.2 V) and VHALF
(approximately 1.65 V) . During product adjustments, if the
reference voltage is mistakenly taken as GND, and a grounding
contact is made, not only would it be impossible to measure the
accurate electrical potential, but also the servo motor would
malfunction, resulting in the application of a strong impact on the
pick up. The following precautionary measures should be strictly
adhered to, in order to avoid such problems. The reference voltage
and GND should not be confused when using the minus probe of a
measurement device. When an oscilloscope is being used special care
should be taken to make sure that the reference voltage is not
connected to the probe of ch1 (on the minus side), while the probe
of ch2 (on the minus side), is connected to GND. Further, since the
body frame of most measurement devices have the same electrical
potential as the minus side of the probe, the body frame of the
measurement device should be set to floating ground.
If the reference voltage is connected to GND by mistake, turn
the regulator OFF immediately, or turn the power OFF . Remove the
filters and wires used for measurements only after the regulator
has been turned OFF. After the power supply is turned on, regulator
ON the following adjustment and measurement are promptly done.
Whenever the product is in the test mode, the software will not
take any protective action. For this reason, special care should be
taken to make sure that no mechanical or electrical shock could be
applied to the product when taking measurements in the test mode.
Whenever the EJECT key is pressed to eject the disk, no other keys,
other than the EJECT key, should be pressed until the disk eject
action has been completed. Press the EJECT key only after the disk
has stopped completely. If the product hangs up turn the power OFF
immediately. Laser didoes may be damaged, if the volume switch for
the laser power adjustment of the pick up unit, is turned.

There are two methods for adjustment, a method whereby the
adjustment is made while monitoring the RF waveform using the
oscilloscope (method 1) and a method whereby the adjustment is made
while checking the RF level in value by OSD (method 2). The
adjustment procedure is shown below. Refer to the paragraph for the
service test mode regarding entering of the test mode and the
operation procedure. Adjustment procedure: 1. Turn the DVD
mechanism module upside down so that the pick up can be adjusted.
When the module is turned upside down, there is a possibility that
the disc is rubbed. So, first place a coin with the thickness of
approximately 1.5mm on a desk, and set the module upside down in a
way that section 1 in the illustration below comes right above the
coin.

2. Install the pick up. (Refer to the section regarding removal
of the pick up from the mechanism unit.) As for the precautions in
handling the pick up, refer to the precautions in handling the PU
as described below. 3. Method 1: Connect the oscilloscope by
referring to the connection drawing so that the RF signal can be
monitored with AGND2 as the reference. Method 2: There is no need
for setting of any equipment. Proceed to step 4. 4. Turn the power
ON, and load the disc for adjustment.(GGV1018) 5. After setting the
disc type to DVD layer 1 in the front end test mode, turn the power
ON, and move the pick up to the inner periphery. (CRG Home) 6. Turn
the LD ON. 7. Set to focus close, and make auto adjustment for all
items under that state, then set to tracking close. And make auto
adjustment for all items under that state as well. 8. Make an
intermediate periphery (ID: 100 000) search, and move the PU to
intermediate periphery. 9. Method 1: Proceed to step 10. Method 2:
After setting to Tracking Open, make all auto adjustments, and set
to Tracking Close this time with a command that can be RF
displayed. Make auto adjustment for all items under that state as
well. 10. Use TORX driver (T2) (GGK1095) for the following. Method
1: While monitoring the RF waveform on the oscilloscope, turn SKEW
adjustment screw A just a little bit in a way that the level will
reach the maximum. While the pick up is at the intermediate
periphery, turn SKEW adjustment screw B just a little bit in a way
that the level will reach the maximum. While the pick up is at the
intermediate periphery, turn SKEW adjustment screw A just a little
bit in a way that the level will reach the maximum. (Make
adjustment in the order of A -> B -> A, Please end the each
adjustment by turning screw clockwise. ) Method 2: While monitoring
the RF leve
