SCHEMATIC DIAGRAM
MODEL : 36HFX72 / 36HF72
WARNING: BEFORE SERVICING THIS CHASSIS, READ THE
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.
