Location: Inside Top of DVD mechanism. 1-3-1 IMPORTANT SAFETY PRECAUTIONS Product Safety Notice Some electrical and mechanical parts have special safety-related characteristics which are often not evident from visual inspection, nor can the protection they give necessarily be obtained by replacing them with components rated for higher voltage, wattage, etc. Parts that have special safety characteristics 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 product safety and electrical 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. Precautions during Servicing A. Parts identified by the # symbol are critical for safety. Replace only with part number specified. 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 the 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 insulation 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 crimping tool to crimp the metal sleeve at its center. Be sure to crimp fully to the complete closure of the tool. L. When connecting or disconnecting the internal connectors, first, disconnect the AC plug from the AC outlet. B. In addition to safety, other parts and assemblies are specified for conformance with regulations applying to spurious radiation. These must also be replaced only with specified replacements. 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 wires 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 about the terminals before soldering. F. Observe that the wires do not contact heat producing 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 replaced, check that 5 - 6 kg of force in any direction will not loosen it. 1-4-1 Safety Check after Servicing Examine the area surrounding the repaired location for damage or deterioration. Observe that screws, parts, and wires have been returned to their original positions. Afterwards, do the following tests and confirm the specified values to verify compliance with safety standards. Chassis or Secondary Conductor Primary Circuit Terminals d' 1. Clearance Distance d When replacing primary circuit components, confirm specified clearance distance (d) and (d’) between soldered terminals, and between terminals and surrounding metallic parts. (See Fig. 1) Table 1 : Ratings for selected area AC Line Voltage Clearance Distance (d) (d’) 120 V ≥ 3.2mm (0.126 inches) Fig. 1 Note: This table is unofficial and for reference only. Be sure to confirm the precise values. 2. Leakage Current Test Exposed Accessible Part 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 (earth ground, power cord plug prongs) and exposed accessible parts. Use an AC voltmeter to measure across the terminals of load Z. See Fig. 2 and the following table. Z AC Voltmeter (High Impedance) 1.5k 0.15 F B Earth Ground Power Cord Plug Prongs Fig. 2 Table 2: Leakage current ratings for selected areas AC Line Voltage Load Z Leakage Current (i) Earth Ground (B) to: 120 V 0.15µF CAP. & 1.5kΩ RES.

When you connect or disconnect the FFC (Flexible Foil Connector) cable, be sure to first disconnect the AC cord. 2. FFC (Flexible Foil Connector) cable should be inserted parallel into the connector, not at an angle. 1. Do not supply hot air to the chip parts around the flat pack-IC for over 6 seconds because damage to the chip parts may occur. Put masking tape around the flat pack-IC to protect other parts from damage. (Fig. S-1-2) 2. The flat pack-IC on the CBA is affixed with glue, so be careful not to break or damage the foil of each pin or the solder lands under the IC when removing it.

Installation (1) Using desoldering braid, remove the solder from the foil of each pin of the flat pack-IC on the CBA so you can install a replacement flat pack-IC more easily. (2) The “I” mark on the flat pack-IC indicates pin 1. (See Fig. S-1-7.) Be sure this mark matches the 1 on the PCB when positioning for installation. Then presolder the four corners of the flat pack-IC. (See Fig. S-1-8.) (3) Solder all pins of the flat pack-IC. Be sure that none of the pins have solder bridges. Instructions for Handling Semi-conductors Electrostatic breakdown of the semi-conductors may occur due to a potential difference caused by electrostatic charge during unpacking or repair work. 1. Ground for Human Body Be sure to wear a grounding band (1MΩ) that is properly 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 (1MΩ) on the workbench or other surface, where the semi-conductors are to be placed. Because the static electricity charge on clothing will not escape through the body grounding band, be careful to avoid contacting semi-conductors with your clothing. Example : < Incorrect > Pin 1 of the Flat Pack-IC is indicated by a " " mark.

Since information about the state of the mechanism is provided to the System Control Circuit only 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 mechanism in Eject mode, in the sequence given. Each procedure assumes that all previous procedures have been completed. IMPORTANT: If any one of these alignments is not performed properly, even if off by only one tooth, the unit will unload or stop and it may result in damage to the mechanical or electrical parts. Alignment 1 Loading Arm, S and T Assembly Install Loading Arm S and T Assembly so that their triangle marks point to each other as shown in Fig. AL2. Alignment 2 Mode Gear Keeping the two triangles pointing at each other, install the Loading Arm T Assembly so that the last tooth of the gear meets the most inside teeth of the Mode Gear.

Preliminary/Final Checking and Alignment of Tape Path Purpose: To make sure that the tape path is well stabilized. Symptom of Misalignment: If the tape path is unstable, the tape will be damaged. 3. Check to see that the tape runs without creasing at Take-up Guide Post [4] or without snaking between Guide Roller [3] and AC Head. (Fig. M3 and M5) 4. If creasing or snaking is apparent, adjust the Tilt Adj. Screw of the AC Head. (Fig. M6) Note: Do not use an Alignment Tape for this procedure. If the unit is not correctly aligned, the tape may be damaged. 1. Play back a blank cassette tape and check to see that the tape runs without creasing at Guide Rollers [2] and [3], and at points A and B on the lead surface. (Refer to Fig M3 and M4.) 2. If creasing is apparent, align the height of the guide rollers by turning the top of Guide Rollers [2] and [3] with a Guide Roller Adj. Screwdriver. (Refer to Fig. M3 and M5.) Azimuth Adj. Screw AC Head X-Value Adj. Screwdriver Tilt Adj. Screw Fig. M6 1-B. X Value Alignment Guide Roller [2] Guide Roller [3] Purpose: To align the Horizontal Position of the Audio/Control/ Erase Head. AC Head B A Take-up Guide Post [4] Fig. M3 Symptom of Misalignment: If the Horizontal Position of the Audio/Control/Erase Head is not properly aligned, maximum envelope cannot be obtained at the Neutral position of the Tracking Control Circuit. 1. Connect the oscilloscope to TP301 (C-PB) and TP303 (CTL) on the Main CBA. Use TP302 (RFSW) as a trigger. 2. Play back the Gray Scale of the Alignment Tape (MH-1) and confirm that the PB FM signal is present. 3. Set the Tracking Control Circuit to the center position by pressing CH UP button then “ PLAY ” button on the unit. (Refer to note on bottom of page 2-6-4.) Lead Surface of Cylinder Tape Fig. M4 Correct Guide Roller Incorrect Tape Take-up Guide Post Tape Fig. M5 2-6-3 4. Use the X-Value Adj. Screwdriver so that the PB FM signal at TP301 (C-PB) is maximum. (Fig. M6) 5. Press CH UP button on the unit until the CTL waveform has shifted by approx. +2msec. Make sure that the envelope is simply attenuated (shrinks in height) during this process so that you will know the envelope has been at its peak. 6. Press CH DOWN button on the unit until the CTL waveform has shifted from its original position (not the position achieved in step 5, but the position of CTL waveform in step 4) by approximately -2msec. Make sure that the envelope is simply attenuated (shrinks in height) once CTL waveform passes its original position and is further brought in the minus direction. 7. Set the Tracking Control Circuit to the center position by pressing CH UP button and then “ PLAY ” button. 1-C. Checking/Adjustment of Envelope Waveform Purpose: To achieve a satisfactory picture and precise tracking. Symptom of Misalignment: If the envelope output is poor, noise will appear in the picture. The tracking will then lose precision and the playback picture will be distorted by any slight variation of the Tracking Control Circuit. 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 properly. 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 oscilloscope to the audio output jack on the rear side of the deck. 2. Play back the alignment tape (MH-1) and confirm that the audio signal output level is 8kHz. 3. Adjust Azimuth Adj. Screw so that the output level on the AC Voltmeter or the waveform on the oscilloscope is at maximum. (Fig. M6) Dropping envelope level at the beginning of track. 1. Connect the oscilloscope to TP301 (C-PB) on the Main CBA. Use TP302 (RF-SW) as a trigger. 2. Play back the Gray Scale on the Alignment Tape (MH-1). Set the Tracking Control Circuit to the center position by pressing CH UP button and then “ PLAY ” button on the unit. Adjust the height of Guide Rollers [2] and [3] (Fig. M3, Page 2-6-3) watching the oscilloscope display so that the envelope becomes as flat as possible. To do this adjustment, turn the top of the Guide Roller with the Guide Roller Adj. Screwdriver. Fig. M7 Dropping envelope level at the end of track. 3. If the envelope is as shown in Fig. M7, adjust the height of Guide Roller [2] (Refer to Fig. M3) so that the waveform looks like the one shown in Fig. M9. 4. If the envelope is as shown in Fig. M8, adjust the height of Guide Roller [3] (Refer to Fig. M3) so that the waveform looks like the one shown in Fig. M9. 5. When Guide Rollers [2] and [3] (Refer to Fig.M3) are aligned properly, there is no envelope drop either at the beginning or end of track as shown in Fig. M9. Note: Upon completion of the adjustment of Guide Rollers [2] and [3] (Refer to Fig. M3), check the X Value by pushing the CH UP or DOWN buttons alternately, to check the symmetry of the envelope. Check the number of pushes to ensure center 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.” Fig. M8 Envelope is adjusted properly.

Do not use the part number shown on these drawings for ordering. The correct part number is shown in the parts list, and may be slightly different or amended since these drawings were prepared. Many electrical and mechanical 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 parts that have these special safety char-acteristics are identified in this manual and its supple-ments; electrical components having such features are identified by the mark " # " in the schematic diagram and the parts list. Before replacing any of these compo-nents, read the parts list in this manual carefully. The use of substitute replacement parts that do not have the same safety characteristics as specified in the parts list may create shock, fire, or other hazards.
