CAUTION FOR SAFETY IN PERFORMING REPAIR

1-1 LASER BEAM SAFETY PRECAUTIONS

This DVD player uses a pickup that emits a laser beam.
Do not look directly at the laser beam coming from the pickup or allow it to strike against your skin.
The laser beam is emitted from th e location shown in the figure. When checking the laser dio de, be sure to keep your eyes at least 30cm away from the pickup lens when the diode is turned on. Do not look directly at the laser beam.
Caution: Use of controls and adjustments, or doing procedures other than those specified herein, may result in hazardous radiation exposure.

1-2 IMPORTANT SAFETY PRECAUTIONS

1-2-1 Product Safety Notice
Some electrical and mechanical parts have special safety-related characteris tics which are often not evi­dent from visual inspection, nor can the protection they give necessarily b e obtained by replacing them with components rated for higher voltage, wattage, etc. Parts that have special safety characteri stics are identified by a ! on schematics and in parts lists. Use of a substitute replacement that does not have the same safety characteristics as the recommended replacement part might create shock, fire, and/or other hazards. The Product’s Safety is under review continuously and new instructions are issued when­ever appropriate. Prior to shipment from the factory, our products are carefully inspected to confirm with the recognized prod uct safety and electr ical codes of the countries in which they are to be sold. However, in order to maintain such compliance, it is equally impor­tant to implement the following precautions when a set is being serviced.
1-2-2 Precautions during Servicing
A. Parts identified by the ! symbol are critical for
safety. Replace only with part number specified.
B. In addition to safety, other parts and assemblies
are specified for conformance with regulations applying to spur io us radiati on. T he se must a lso be replaced only with specified re pla ce men ts. Examples: RF converters, RF cables, noise block­ing capacitors, and noise blocking filters, etc.
C. Use specified internal wiring. Note especially:
1)Wires covered with PVC tubing
2)Double insulated wi res
3)High voltage leads
D. Use specified insulating materials for hazardous
live parts. Note especially:
1)Insulation tape
2)PVC tubing
3)Spacers
4)Insulators for transistors
E. When replacing AC primary side components
(transformers, power cord, etc.), wrap ends of wires securely abo ut the terminals before solder­ing.
F. Observe that the wires do not contact heat produc-
ing parts (heatsinks, oxide metal film resistors, fus­ible resistors, etc.).
G. Check that replaced wires do not contact sharp
edges or pointed parts.
H. When a power cord has been repl ace d, c he ck that
5 - 6 kg of force in any direction will not loosen it.
I. Also check areas surrounding repaired locations. J. Be careful that foreign objects (screws, solder
droplets, etc.) do not remain inside the set.
K. Crimp type wire connector
The power transformer uses crimp type connec­tors which connect the power cord and the primary side of the transformer. When replacing t he trans­former, follow these steps carefully and precisely to prevent shock hazards. Replacement procedure
1)Remove the old connector by cutting the wires at a point close to the connector.
Important: Do not re-use a connector. (Discard it.)
2)Strip about 15 mm of the insul ation from the ends of the wires. If the wires are stranded, twist the strands to avoid frayed conductors.
3)Align the lengths of the wires to be connected. Insert the wires fully into the connector.
4)Use a cri mping tool to crimp the metal sleeve at its center. Be sure to crimp fully to the compl ete closure of the tool.
L. When connecting or disconnecting the internal
connectors, first, disconnec t the AC plug from the AC outlet.

1-2-3 Safety Check after Servicing
Examine the area surrounding the repaired location for damage or deterioration. Observe that screws, parts, and w ires have been returned to thei r original positions. Afterwards, do the following tests and con­firm the specified values to verify compliance with safety standards.
1. Clearance Distance
When replacing pr imary circuit components, confir m specified clearance di sta nc e ( d ) and ( d’ ) between sol­dered terminals, and between terminals and sur­rounding metallic parts. (See Fig. 1-2-1)
Table 1-2-1 : Ratings for selected area
AC Line Voltage Clearance Distance (d), (d’)
220 to 240 V
Note: This table is unofficial and for reference only.
Be sure to confirm the precise values.
3 mm(d)
6 mm(d’)
2. Leakage Current Test
Confirm the specified (or lower) leakage current between B (earth ground, power cord plug prongs) and externally exposed accessible parts (RF termi­nals, antenna terminals, video and audio input and output terminals, microphone jacks, earphone jacks, etc.) is lower than or equal to the specified value in the table below.
Measuring Method (Power ON) :
Insert load Z between B (ear th ground, power cord plug prongs) and exposed accessible par ts. Use an AC voltmeter to measure across the terminal s of load Z. See Fig. 1-2-2 and the following table.

1-3-4 Instructions for Handling
Semi-conductors
Electrostatic breakd own of the semi-conductor s may occur due to a pote ntial dif ference caused by electro­static charge during unpacking or repair work.
1. Ground for Human Body
Be sure to wear a grounding band (1M) that i s prop ­erly grounded to remove any static electricity that may be charged on the body.
2. Ground for Workbench
(1) Be sure to place a conductive sheet or copper
plate with proper grounding (1M) on the work­bench or other surface, where the semi-conduc­tors are to be placed. Beca us e the s tatic el ec tr ic i ty charge on clothing will not escape through the body grounding band, be careful t o avoid contact­ing semi-conductors with your clothing.

Cautions On Batteries
Use “AA” (R6P) batteries in this remote control unit. Replace the batteries with new ones approximately once a year, though this depends on the frequency with which the remote control unit is used. If the remote control unit does not operate from close to the main unit, replace the batteries with new ones, even if less then a year has passed.
The included battery is only for verifying operation.
Replace it with a new battery as soon as possible. When inserting the batteries, be careful to do so in
the proper direction, following the and marks in the remote control unit’s battery compartment. To prevent damage or battery fluid leakage:
Do not use a new battery with an old one. Do not use two different types of batteries such as alkaline and manganese. Do not short-circuit, disassemble, heat or dispose
of batteries in flames. Remove the batteries when not planning to use the remote control unit for a long period of time. If the batteries should leak, carefully wipe off the fluid from the inside of the battery compartment, then insert new batteries.

4-3 ALIGNMENT PROCEDURES OF MECHANISM

The following procedures describe how to align the individual gears and levers that make up the tape loading/unloading mechanism. Since information about the state of the mechanism is provided to the System Control Circ uit onl y through the Mode Switch, it is essential that the correct relationship between individual gears and levers be maintained.
All alignments are to be performed with the mech-
anism in Eject mode, in th e sequence given. Each
procedure assumes tha t al l pr evious pro ce dures have been completed.
IMPORTANT:
If any one of these ali gnments i s not perfor med prop ­erly, even if off by only one tooth, the unit will unload or stop and it may result in damage to the me chan ic al or electrical parts.

Note: Upon completion of the adjustment of Guide
Rollers [2] and [3] (Refer to Fig. 5-4-3), check the X Value by pushing the CH UP or DOWN buttons alter ­nately, to check the symmetr y of the envelope. Check the number of pushes to ensure preset position. The number of pushes CH UP button to achieve 1/2 level of envelope should match the number of pushes CH DOWN button from center. If required, redo the “X Value Alignment.”

1-D. Azimuth Alignment of Audio/Control/
Erase Head
Purpose:
To correct the Azimuth alignment so that the Audio/ Control/Erase Head meets tape tracks proper ly.
Symptom of Misalignment:
If the position of the Audio/Control/Erase Head is not properly aligned, the Audio S/N Ratio or Frequency Response will be poor.
1. Connect the oscillosc ope to the audio output jack on the rear side of the deck.
2. Playback the alignment tape (MH-2) and confirm that the audio signal output level is 8kHz.
3. Adjust Azimuth Adj. Screw so that the output level on the AC Vo ltmeter or the waveform on the oscil­loscope is at maximum. (Fig. 5-4-6)
Note: Upon completion of the adjustment of Azimuth Adj. Screw, check the X Value by pushing the CH UP or DOWN buttons alternate ly, to check the symmetr y of the envelope. Check the number of pushes to ensure preset position. The number of pushes CH UP button to achieve 1/2 level of envelope should match the number of pushes CH DOWN button from center. If required, redo the “X Value Alignment.”
2. When the tape has been curled up or bent, turn the alignment screw to adjust the height of REV Post. (Refer to Fig. M11 and M13.)

1-E. Checking and Alignment of Tape
Path during reversing
Purpose:
To make sure that th e tape path is well st abil ized dur­ing reversing.
Symptom of Misalignment:
If the tape path is unstable du ring reversing, the tape will be damaged.
Note: Do not use an Align ment Tape for this proce­dure. If the unit is not co rrectly aligned, the tape may be damaged.
1. Inser t a black cassette tape into the tray and set the unit to REV. Then confirm if the tape has b een curled up or bent at the Take-up Guide Post[4] or REV Post[5]. (Refer to Fig. M11 and M12.)

Many electrical and mec hanical parts in this chassis have special characteristics. These characteristics often pass unnoticed and the protection afforded by them cannot necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement par ts that have these spe­cial safety characteristics a re identifie d in this m anual and its supplements; electrical components having such features are identified by the ma rk " ! " in the schematic diagram and the parts list. Before replacing any of these components, read the parts list in this manual carefully. The use of substitute replacement parts tha t do not have the same safety characteristic s as specified in the parts list may create shock, fire, or other hazards.
