SCHEMATIC DIAGRAM
MODEL : 32WL55A / 32WL55E / 32WL55R / 32WL55T
WARNING : BEFORE SERVICING THIS CHASSIS, READ THE "SERVICE SAFETY PRECAUTIONS" 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 SERVICE SAFETY PRECAUTIONS 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
1RF = Fuse resistor of 1 watt
K = ±10%
2. CAPACITOR
Unless otherwise noted in schematic, all capacitor values less than 1 are expressed in
F, and the values more than 1 in pF.
All capacitors are ceramic 50V, unless otherwise noted as the following marks.
3. The parts indicated with "
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 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.
G = ±2%
F = ±1%
