Toshiba 46HM84, 52HM84, 62HM84 Schematic

SCHEMATIC DIAGRAM

MODEL : 46HM84/52HM84/62HM84

WARNING : BEFORE SERVICING THIS CHASSIS, READ THE “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% toler ance
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

±10% G = ±2% F = ±1%

K =

2. CAPACITOR Unless otherwise noted in schematic, all capacitor values less than 1 are expressed in
the values more than 1 in pF.
All capacitors are ceramic 50V, unless otherwise noted as the following marks.
