SAFETY PRECAUTIONS
NOTICE:
Comply with all cautions and safety related notes
located on or inside the cabinet and on the chassis.
1. When replacing a chassis in the instrument, all the
protective devices must be put back in place, such as
barriers, non-metallic knobs, adjustment and
compartment covers/shields, isolation resistors/
capacitors, etc.
2. When service is required, observe the original lead-
dress. Extra precautions should be taken to assure
correct lead dress in the high voltage circuit.
3. Always use the manufacturer's replacement
components. Especially critical components as
indicated on the circuit diagram should not be
replaced by other manufacturer's. Furthermore,
where a short-circuit has occurred, replace those
components that indicate evidence of overheating.
4. Before returning an instrument to the customer, the
service technician must thoroughly test the unit to be
certain that it is completely safe to operate without
danger of electrical shock, and be sure that no
protective device built into the instrument by the
manufacturer has become defective or inadvertently
defeated during servicing. Therefore, the following
checks should be performed for the continued
protection of the customer and service technician.
Leakage Current Cold Check
With the AC plug removed from the AC120V, 60Hz
source, place a jumper across the two plug prongs.
Turn the AC power switch on. Using an insulation
tester (DC500V), connect one lead to the jumpered
AC plug and touch the other lead to exposed metal
parts (antennas, screwheads, metal overlays, control
shafts, etc.), particularly any exposed metal part
having a return path to the chassis. Exposed metal
parts having a return path to the chassis should have
a minimum resistor reading of 0.3 Mohm and a
maximum resistor reading of 5 Mohm. Any resistor
value below or above this range indicates an
abnormality which requires corrective action.
Exposed metal parts not having a return path to the
chassis will indicate an open circuit.
Leakage Current Hot Check
Plug the AC line cord directly into a AC120V, 60Hz
outlet (do not use an isolation transformer for this
check).
Turn the AC power switch on. Using a "Leakage
Current Tester", measure for current from all
exposed metal parts of the cabinet (antennas,
screwheads, metal overlays, control shaft, etc.),
particularly an exposed metal part having a return
path to the chassis, to a known ground (earth) (water
pipe, conduit, etc.). Any current measured must not
exceed 0.5 mÀ.

ANY MEASUREMENTS NOT WITHIN THE LIMITS
OUTLINED ABOVE ARE INDICATIVE OF A
POTENTIAL SHOCK HAZARD AND MUST BE
CORRECTED BEFORE RETURNING THE UNIT TO
THE CUSTOMER.
PRODUCT SAFETY NOTICE
Many electrical and mechanical parts have special
safety-related characteristics. These are often not
evident from visual inspection nor can the protection
afforded by them necessarily be obtained by using
replacement components rated for a higher voltage,
wattage, etc. Replacement parts which have these
special safety characteristics are identified in this
Service Manual. Electrical components having such
features are identified by marking with a /Non the
schematics and the parts list in this Service Manual.
The use of a substitute replacement component which
does not have the same safety characteristics as the
HITACHI recommended replacement one, shown in the
parts list in this Service Manual, may create shock, fire,
or other hazards. Product safety is continuously under
review and new instructions are issued from time to
time. For the latest information, always consult the
current HITACHI Service Manual. A subscription to, or
additional copies for, HITACHI Service Manual may be
obtained at a nominal charge from HITACHI SALES
CORPORATION.

1.Markings in schematic diagrams
1) Parts marked " IN " with circuit numbers in the
schematic diagrams are discrete parts.
2) Parts marked " € " with circuit numvers in the
schematic diagram are leadless parts.
1. Identifications of sides A/B in circuit board diagrams
1) Board having a pattern on one side and parts on
both sides.
Side A: Shows discrete parts, viewed from the
pattern side.
Side B: Shows leadiess parts, viewed from the
pattern side.
2) Board having patterns on both sides and parts on
both sides.
Side A: Shows parts and patterns which can be
seen when the case is opened.
Side B: Shows parts and the pattern on the back of
side A.
2. Table for indexing locations of parts
This table shows locations of each part on the circuit
board diagrams. The locations are indicated using the
guide scales on the external lines of diagrams.

1.Markings in schematic diagrams
1) Parts marked " IN " with circuit numbers in the
schematic diagrams are discrete parts.
2) Parts marked " @ " with circuit numvers in the
schematic diagram are leadless parts.
Cautions when using circuit board diagrams
1. Identifications of sides A/B in circuit board diagrams
1) Board having a pattern on one side and parts on
both sides.
Side A: Shows discrete parts, viewed from the
pattern side.
Side B: Shows leadless parts, viewed from the
pattern side.
2) Board having patterns on both sides and parts on
both sides.
Side A: Shows parts and patterns which can be
seen when the case is opened.
Side B: Shows parts and the pattern on the back of
side A.
2. Table for indexing locations of parts
This table shows locations of each part on the circuit
board diagrams. The locations are indicated using the
guide scales on the external lines of diagrams.

© Trouble shooting the Switching Regulator
This section summarizes the troubleshooting of defects in the switching regulator. Perform diagnosis, taking each
defective phenomenon into consideration. Even if the same defective phenomenon appears, it may be caused by
other circuits, not by the switching regulator, so use this item as a reference.

Troubleshooting by Observing Defective Phenomena
If the switching regulator is normal and there is a defect in another circuit (shorting between the power supply and
ground of the secondary circuit), the protective function of IC851 operates and the power is not turned on. If a
defect occurs in the switching regulator, a phenomenon such that the VCR power is not turned on or the power fuse
has blown also occurs.
