SCHEMATIC DIAGRAMS FOR MODELSTX-32PS11D, TX-32PS11F, TX-32PS11P, TX-32PS11D/BTX-29PS11D, TX-29PS11F, TX-29PS11P, TX-29PS11D/BTX-28PS11D, TX-28PS11F(GP2 CHASSIS)NOTE1. RESISTORAll resistors are carbon ¼W resistor, unless marked otherwise.Unit of resistance is OHM (Ω) (k=1,000, M=1,000,000)2. CAPACITORSAll capacitors are ceramic 50V unless marked otherwise.Unit of capacitance is μF unless otherwise stated.3. COILUnit of inductance is μH, unless otherwise stated.4. TEST POINTTest Point Position5. EARTH SYMBOLChassis Earth (Cold)Line Earth (Hot)6. VOLTAGE MEASUREMENTVoltage is measured by a d.c. voltmeter.Measurement conditions are as follows:Power source a.c. 220V-240V, 50HzReceiving Signal Colour Bar signal (RF)All customer controls Maximum position7.Indicates the Video signal pathIndicates the Audio signal pathThese schematic diagrams are the latest at time of printing and are subject to change without notice.REMARKSa. Do not touch the hot part, or the hot and cold parts at the same time, as you are liable to a shock hazard.b. Do not short circuit the hot and cold circuits as electrical components may be damaged.c. Do not connect an instrument, such as an oscilloscope, to the hot and cold circuits simultaneously as this may causefuse failure. Connect the earth of the instruments to the earth connection of the circuit being measured.d. Make sure to disconnect the power plug before removing the chassis.NOTE1. The Power Supply Circuit contains a circuit area, which uses a separate power supply to isolate the earth connection.The circuit is defined by HOT and COLD indications in the schematic diagram. All circuits, except the Power Circuit, areCOLD.IMPORTANT SAFETY NOTICEComponents identified by mark have special characteristicsimportant for safety. When replacing any of these components, useonly manufacturers' specified parts.27
