FILE NO. 020-200402 CIRCUIT DIAGRAMS Color Television 32AF44 32AFX54 DOCUMENT CREATED IN JAPAN, July, 2004 SCHEMATIC DIAGRAM MODEL : 32AF44/32AFX54 WARNING: BEFORE SERVICING THIS CHASSIS, READ THE "X-RAY RADIATION PRECAUTION", "SAFETY PRECAUTION" AND "PRODUCT SAFETY NOTICE" ON THE MANUAL FOR THIS MODEL. CAUTION: The international hazard symbols " " in the schematic diagram and the parts list designate components which have special characteristics important for safety and should be replaced only with types identical to those in the original circuit or specified in the parts list. The mounting position of replacements is to be identical with originals. Before replacing any of these components, read carefully the PRODUCT SAFETY NOTICE on the MANUAL for this model. Do not degrade the safety of the receiver through improper servicing. NOTE: 1. RESISTOR Resistance is shown in ohm [K = 1.000, M = 1.000.000]. All resistors are 1/6W and 5% tolerance carbon resistor, unless otherwise noted as the following marks. 1/2R = Metal or Metal oxide of 1/2 watt 1/2S = Carbon compsistion of 1/2 watt 1RF = Fuse resistor of 1 watt 10W = Cement of 10 watt K = ±10% G = ±2% F = ±1% Unless otherwise noted in schematic, all capacitor values less than 1 are expressed in µF, and the values more than 1 in pF. All capacitors are ceramic 50V, unless otherwise noted as the following marks. Electolytic capacitor 3. The parts indicated with " Mylar capacitor 2. CAPACITOR " have special characteristics, and should be replaced with identical parts only. 4. Voltages read with DIGITAL MULTI-METER from point indicated to chassing ground, using a color bar signal with all controls at normal, line voltage at 220 volts. 5. Waveforms are taken receiving color bar signal with enough sensitivity. 6. Voltage reading shown are nominal values and may vary ±20% except H.V.
