SAFETY CHECK-OUT
(US Model only) After correcting the original service problem, perform the following safety checks before releasing the set to the customer: 1. Check the area of your repair for unsoldered or poorly-soldered connections. Check the entire board surface for solder splashes and bridges. 2. Check the interboard wiring to ensure that no wires are "pinched" or contact high-wattage resistors. 3. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them out to the customer and recommend their replacement. 4. Look for parts which, though functioning, show obvious signs of deterioration. Point them out to the customer and recommend their replacement. 5. Check the line cord for cracks and abrasion. Recommend the replacement of any such line cord to the customer. 6. Check the B+ voltage to see it is at the values specified. 7. Check the antenna terminals, metal trim, "metallized" knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below. LEAKAGE TEST The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microamperes). Leakage current can be measured by any one of three methods. 1. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers' instructions to use these instruments. 2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job. 3. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The "limit" indication is 0.75V, so analog meters must have an accurate lowvoltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2V AC range are suitable. (See Fig. A)

SERVICE NOTE
· Note for Repair Make sure that the flat cable and flexible board are not cracked or bent at the terminal. Do not insert the cable insufficiently nor crookedly.
Cut and remove the part of gilt which comes off at the point. (Take care that there are some pieces of gilt left inside)

DSR-20MD/20MDP SECTION 4 PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this, the necessary note is printed in each block)
For printed wiring boards: · b : Pattern from the side which enables seeing. (The other layers' pattern are not indicated) · Circled numbers refer to waveforms. · Through hole is omitted. · There are few cases that the part printed on diagram isn't mounted in this model. · Chip parts. Transistor
C 6 5 4 4 5 6 4 5 1 2 3
Measuring conditions voltege and waveform: · Voltages and waveforms are measured between the measurement points and graound when color bar signal input.They are reference values and reference waveforms.* (VOM of DC 10 M input impedance is used) · Voltage values change depending upon input impedance of VOM used. * Indicated by the color red. Note: The components identified by mark 0 or dotted line with mark 0 are critical for safety. Replace only with part number specified. Note: Les composants identifiés par une marque 0 sont critiques pour la sécurité. Ne les remplacer que par une piéce por tant le numéro spécifié.

For schematic Diagram: · All capacitors are in µF unless otherwise noted. pF : µµF 50V or less are not indicated except for electrolytics and tantalums. · Chip resistors are 1/10 W unless otherwise noted. k : 1000, M : 1000k. · Caution when replacing chip parts. New parts must be attached after removal of chip. Be careful not to heat the minus side of tantalum capacitor, because it is damaged by the heat. · Some chip part will be indicated as follows.
When indicating parts by reference number, please include the board name.
