1. SERVICE PRECAUTIONS1.1 SERVICE PRECAUTIONS

1.2 NOTES ON SOLDERING

- Service Precaution

1. You should conform to the regulations govering 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 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 aconnector is plugged or unplugged.7. : Hot area. Be careful not to burn yourself.

NOTES ON SOLDERING For 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.5 6 7 8

8. EACH SETTING AND ADJUSTMENT8.1 DVD ADJUSTMENT

1) PrecautionsThis 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 ismistakenly taken as GND, and a grounding contact ismade, not only would it be impossible to measure theaccurate electrical potential, but also the servo motorwould malfunction, resulting in the application of astrong impact on the pick up. The following precaution-ary measures should be strictly adhered to, in order toavoid such problems.The reference voltage and GND should not be confusedwhen using the minus probe of a measurement device.When an oscilloscope is being used special care shouldbe taken to make sure that the reference voltage is notconnected to the probe of ch1 (on the minus side),while the probe of ch2 (on the minus side), is connectedto GND. Further, since the body frame of most mea-surement devices have the same electrical potential asthe minus side of the probe, the body frame of the mea-surement device should be set to floating ground.

If the reference voltage is connected to GND by mis-take, turn the regulator OFF immediately, or turn thepower OFF.

Remove the filters and wires used for measurementsonly after the regulator has been turned OFF.After the power supply is turned on, regulator ON thefollowing adjustment and measurement are promptlydone.

Whenever the product is in the test mode, the softwarewill not take any protective action. For this reason,special care should be taken to make sure that nomechanical or electrical shock could be applied to theproduct 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 bepressed until the disk eject action has been complet-ed.Press the EJECT key only after the disk has stoppedcompletely.If the product hangs up turn the power OFF immedi-ately. Laser didoes may be damaged, if the volume switch forthe 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 level value on the OSD display, turn the 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. ) If the error is not good, please perform Method 1 again.

11. Turn the power OFF in the test mode, and after confirming that the disc has stopped, eject the disc.12. Apply adhesive for fixing the SKEW and lock the screw. Refer to the illustration below for the adhesion points.1 2 3 4
