Alignment and Adjustment
2-2-2 SKEW Adjustment Method
Needed to minimize the variations in Skew of the Pickup unit and to provide optimum match with the recorded signal on the Disc. 1) Connect an Oscilloscope to the "Pin 29 of RIC1" Test Point (See Fig. 2-1). 2) Connect Power, Open the Tray and Play the TDV-533 Disc, Chapter 14. Set the Oscilloscope Range as follows : (Voltage ; 20mV/Div., Frequency ; 10m Sec.) 3) Adjust the Screws "A" and "B" (See Fig. 2-2) using a Hex screwdriver until you obtain a Flat Waveform and the picture is stable. Then, go to Chapter 1 and make sure the Waveform is Flat here as well. If not, you have to go back to Chapter 14 and adjust again. If you cannot obtain a Flat waveform, then the unit is defective. Note : The Deck must be in a horizontal position. Use both "A" and "B" screws to adjust.

1-1 Safety Precautions
1) Before returning an instrument to the customer, always make a safety check of the entire instrument, including, but not limited to, the following items: (1) Be sure that no built-in protective devices are defective or have been defeated during servicing. (1)Protective shields are provided to protect both the technician and the customer. Correctly replace all missing protective shields, including any removed for servicing convenience. (2)When reinstalling the chassis and/or other assembly in the cabinet, be sure to put back in place all protective devices, including, but not limited to, nonmetallic control knobs, insulating fish papers, adjustment and compartment covers/shields, and isolation resistor/capacitor networks. Do not operate this instrument or permit it to be operated without all protective devices correctly installed and functioning. (2) Be sure that there are no cabinet openings through which adults or children might be able to insert their fingers and contact a hazardous voltage. Such openings include, but are not limited to, excessively wide cabinet ventilation slots, and an improperly fitted and/or incorrectly secured cabinet back cover. (3) Leakage Current Hot Check-With the instrument completely reassembled, plug the AC line cord directly into a 120V AC outlet. (Do not use an isolation transformer during this test.) Use a leakage current tester or a metering system that complies with American National Standards institute (ANSI) C101.1 Leakage Current for Appliances and Underwriters Laboratories (UL) 1270 (40.7). With the instrument's AC switch first in the ON position and then in the OFF position, measure from a known earth ground (metal water pipe, conduit, etc.) to all exposed metal parts of the instrument (antennas, handle brackets, metal cabinets, screwheads, metallic overlays, control shafts, etc.), especially any exposed metal parts that offer an electrical return path to the chassis. Any current measured must not exceed 0.5mA. Reverse the instrument power cord plug in the outlet and repeat the test. See Fig. 1-1. Any measurements not within the limits specified herein indicate a potential shock hazard that must be eliminated before returning the instrument to the customer.
(READING SHOULD NOT BE ABOVE 0.5mA) DEVICE UNDER TEST TEST ALL EXPOSED METER SURFACES 2-WIRE CORD ALSO TEST WITH PLUG REVERSED (USING AC ADAPTER PLUG AS REQUIRED) EARTH GROUND
LEAKAGE CURRENT TESTER
Fig. 1-1 AC Leakage Test
(4) Insulation Resistance Test Cold Check-(1) Unplug the power supply cord and connect a jumper wire between the two prongs of the plug. (2) Turn on the power switch of the instrument. (3) Measure the resistance with an ohmmeter between the jumpered AC plug and all exposed metallic cabinet parts on the instrument, such as screwheads, antenna, control shafts, handle brackets, etc. When an exposed metallic part has a return path to the chassis, the reading should be between 1 and 5.2 megohm.

COPY PROTECTION
· Digital Audio disc
· DTS disc
· MP3 disc
· Many DVD discs are encoded with copy protection. Because of this, you should only connect your DVD player directly to your TV, not to a VCR. Connecting to a VCR results in a distorted picture from copy-protected DVD discs.
Play Region Number
Both the DVD player and the discs are coded by region. These regional codes must match in order for the disc to play. If the codes do not match, the disc will not play. The Region Number for this playe | File name 27095303843_CH5.pdf5. Disassembly and Reassembly

6-2-2 SKEW Adjustment Method
Needed to minimize the variations in Skew of the Pickup unit and to provide optimum match with the recorded signal on the Disc. 1) Connect an Oscilloscope to the "Pin 29 of RIC1" Test Point (See Fig. 6-1). 2) Connect Power, Open the Tray and Play the TDV-533 Disc, Chapter 14. Set the Oscilloscope Range as follows : (Voltage ; 20mV/Div., Frequency ; 10m Sec.) 3) Adjust the Screws "A" and "B" (See Fig. 6-2) using a Hex screwdriver until you obtain a Flat Waveform and the picture is stable. Then, go to Chapter 1 and make sure the Waveform is Flat here as well. If not, you have to go back to Chapter 14 and adjust again. If you cannot obtain a Flat waveform, then the unit is defective. Note : The Deck must be in a horizontal position. Use both "A" and "B" screws to adjust.

Advantages and disadvantages of linear power supply 1) Advantages : Little noise because the output waveform of transformer is sine wave. 2) Disadvantages : OE Additional margin is required because Vs is changed (depending on power source). (The regulator loss is caused by margin design). ´ Greater core size and condensor capacity are needed, because the transformer works on a single power frequency. v Vout

1) Prevent residual high voltage at the terminals of switch during switch off/Suppress noise. High inverted power occurs at switch (PQR11) off, because of the 1st winding of transformer : (V=-L1 xdi/dt. L1 : Leakage Induction) A very high residual voltage exist on both terminals of PQR11 because dt is a very short. 2) SNUBBER circuit protects PQR11 from damage through leakage voltage suppression by RC, (Charges the leakage voltage to PDS11, PER13, PCD12 and discharges to PRS13).

When Vin supplied, driving current Ig occurs throuhg the PRR11. By this IC (=Hfe x Ig) occurs throug the PQR11 and the Vb is inducted to base winding coil NB of PQR11. By inducted Vb, Ib start flow and the PQR11 is saturated (S/W ON). Ib is constant and Ic increases in Proportion to time. After constant time passed Ib become to shortage and PQR11 is cut OFF (S/W OFF).
