AG-DV2500P -2- AG-DV2500E -3- SAFETY PRECAUTIONS GENERAL GUIDELINES 1. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been over-heated or damaged by the short circuit. 2. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly installed. 3. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards. ELECTROSTATICALLY SENSITIVE (ES) DEVICES Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically sensitive (ED) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and semiconductor "chip" components. The following techniques should be used to help reduce the incidence of component damage caused by static electricity. 1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist trap device, which should be removed for potential shock reasons prior to applying power to the unit under test. 2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as alminum foil, to prevent electrostatic charge buildup or exposure of the assembly. 3. Use only a grounded tip soldering iron to solder or unsolder ES devices. 4. Use only an anti-static solder removal device classified as "anti-static" can generate electrical charges sufficient to damage ES devices. 5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices. 6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (most replacement ES devices are package with leads electrically

SECTION 4 TECHNICAL DESCRIPTION 4.1 (1) (2) (3) (4) 4.2 PRODUCT OUTLINE DV Standard/Mini cassette compatible 4.5 hours consecutive recording/playback possible using Standard cassette (DV270) 5.25-inch half hight bay size compact design (mechanism unit only) Layout-free with horizontal and vertical positioning capability MECHANISM 4.2.1 Mechanism out line Item Compatible cassette Loading system Head cleaner Reel drive FWD/REV reel switching Tension control AG-DV2500 Mini/Standard Cassette compatible Front loading Yes (solenoid) Reel motor (1 motor) Swing gear switching Tension band method (SUP/TU dual control) 4.2.2 Regarding standard cassette AG-DV2500 is newly compatible with DV standard size cassettes. Fig. 4.2.1 shows a size comparison with conventional Mini cassette. All dimensions differ, including cassette thickness in addition to height and width. · Mini Cassette 66 48 14 .9 12.2 32.5 · Standard Cassette 125 78 38.7 5 14.6 61.6 Fig. 4.2.1 Comparison Between Mini Cassette and Standard Cassette 4-1 4.2.3 Cassette housing operation outline (1) Inserted cassette type detection In its initial state, the reel disk is in the standard position, and only when a mini cassette is inserted it changes to the mini cassette position. As explained in Section 2, it is the reel change plate (Fig. 4.2.5) that changes the position of the reel disk. As previously compared in 4.2.1, the thickness of standard and mini cassettes differ. Standard cassette thickness : 14.6 mm Mini cassette thickness : 12.2 mm Based on this difference, it is differentiated within the cassette housing whether the inserted cassette is standard or mini. 1) When a mini cassette is inserted The reel disk position changes to the mini cassette position at the same time the cassette housing performs the intake movement. The reel change bracket (Fig. 4.2.3) located on the right side of the cassette housing is linked to the reel change plate (Fig. 4.2.4), so when the cassette housing intake movement occurs the reel change plate also moves, thereby changing to the mini cassette position. Cassette Holder Bar Fig. 4.2.2 Cassette Holder Bar Cassette Holder Bar Reel Change Bracket Fig. 4.2.3 Reel Change Bracket 2) When a standard cassette is inserted The cassette holder bar (Fig. 4.2.2) is pushed up for the amount of thickness differential in relation to mini cassette, and in conjunction the reel change bracket (Fig. 4.2.3) located on the right side of the cassette housing moves upward. As a result, the link with the reel change plate (Fig. 4.2.4) becomes free, and the reel disk becomes held in the standard position even while the cassette housing is undergoing the intake movement. Reel Change Plate Fig. 4.2.4 Reel Change Plate 4-2 (2) Mini Cassette Incorrect Insertion Prevention Function Sub Flap Fig. 4.2.5 Sub Flap Sub flaps are attached on the cassette guide assembly located on the bottom end of the cassette housing door. These two sub flaps are designed to open when bo

SECTION 3 ELECTRICAL ADJUSTMENTS 3.1 PRECAUTIONS FOR ELECTRICAL ADJUSTMENTS 3.1.3 Signals required for adjustments NTSC and PAL color bar signals are required on "3.3 VIDEO SYSTEM ADJUTMENT". NTSC: 100% color bars (100, 0, 100, 0) (Without SETUP) 100% color bars (100, 7.5, 100, 7.5) (With SETUP) PAL: 100% color bars (100, 0, 100, 0) (PAL does not use SETUP.) (1) Composite 100% color bars 3.1.1 Measuring instruments and Tools required for adjustments (1) Measuring instruments · Oscilloscope: 2-trace, 100 MHz or more. · NTSC/PAL waveform monitor (WFM) · NTSC/PAL Composite and Y/C video signal generator · Frequency counter: 10 MHz or more, resolution 100 mV or less. · Monitor TV (2) Tools 1 Alignment tape B Vp-p Electrical adjustments should be performed only when they are required, for example, during maintenance. Electrical adjustments that are possible only after mechanism adjustments should be performed after completing these. Before proceeding to perform electrical adjustments, be sure to warm up the unit for at least 10 minutes after turning it on. Use the 10:1 probe with the oscilloscope unless otherwise specified. NTSC : A = 0.714, B = 0.286, C = 0.0536S (SETUP 7.5%) PAL : A = 0.7, B = 0.3, C = 0 A Vp-p C Vp-p 1.24 Vp-p VFK1842 Fig. 3.1.3 (1) (2) Y/C 100% color bars Y/C (Y) NTSC : A = 0.714, B = 0.286, C = 0.0536 (SETUP 7.5%) PAL : A = 0.7, B = 0.3, C = 0 2 Rewrite board (Jig connector) VFK1846 A Vp-p C Vp-p 1.0 Vp-p Table 3-1-1 3.1.2 Alignment tape specifications VFK1842 No. 1 2 Video signal Moving image Audio signal Moving image audio Time (min.) 10 10 Applications Block noise check ·Interchangeability adjustment ·Video/audio play circuit check/adjustment B Vp-p Y/C (C) NTSC : A = 0.286, B = 0.84 [SETUP 7.5%] (0.9 [SETUP 0%]) PAL : A = 0.3, B = 0.885 Color bars 1 kHz B Vp-p A Vp-p Table 3-1-2 Fig. 3.1.3 (2) 3-1 3.1.4 Notes for adjustments Since the AG-DV2500 is compatible with the recording and playback of the NTSC and PAL signals, it is required that both NTSC and PAL be adjusted. The NTSC and PAL signals use different Y signal V/S ratios and color levels. Be sure to use the specified signals for the adjustments. Both the NTSC and PAL signals use a variety of signals differing in the Y levels and color levels, etc. Also note that the NTSC signals include signals both with and without the Setup component. The AG-DV2500 is provided with input and output level adjustment capabilities only. If a signal of the specified level for color and setup is not available, read the following for the substitution. (1) Y level adjustments (Both of NTSC and PAL) If the available Y signal contains a white level of 100 IRE (PAL: 0.7 Vp-p), the signal can be used in the adjustment as described in the given procedure. If the input signal has the setup, adjust the luminance level from the pedestal to the white peak including the setup. (2) Setup level adjustment (NTSC only) The NTSC signal generator usually generates a signal with the Setup

Table 2-1-1 2.1.1 Precautions 1) Be sure to apply a screw securing torque when attaching a part. The securing torque should be 0.14 N/m (1.4 kgf/cm) unless otherwise specified. 2) Always unplug the power cord of the set before attaching, removing or soldering a part. 3) When unplugging a connector, do not pull the wire but grasp the connector body. 4) Do not make an adjustment or rotate a potentiometer blindly while the source of trouble is not identified. 5) Before adjusting electrical circuitry, be sure to wait for more than 10 minutes after turning the power on. 2.1.3 Equipment required for adjustments 1 Alignment tape 4 Torque screwdriver VFK1845 VFK1842 VFK1209 Replaceable bit (long type) 2 Cassette torque meter 5 REWRITE board (Connector board) VFK1843 for FWD mode VFK1844 for REV mode VFK1846 3 Post driver VFK1149 Table 2-1-2 2-1 2.2 DISASSEMBLY/ASSEMBLY OF THE MECHANISM 2.2.2 Mode transition To change the mechanism mode manually, rotate the emergency gear of the mode motor assembly shown in Fig. 2.2.1 as below while holding it down. The mechanism mode can be changed by applying 3 V DC to the mode motor electrodes. The MINI and STD reel positions can be changed over by manually sliding the reel change plate. 2.2.1 Mechanism position for disassembly/assembly The mechanism should basically be disassembled and assembled in the unloading end (No Cassette) position. However, other mechanism position is sometimes required for disassembly or assembly. In such a case, the required position is specified every time in the descriptions in 2.6, "Replacement of major parts".
