SAFETY PRECAUTIONS
1. Before returning an instrument to the customer, always make a safety check of the entire instrument, including but not limited to the following items:
a) Be sure that no built-in protective devices are
defective and/or have been deleted during servicing. (1) Protective shields are provided on this chassis to protect both the technician and the customer. Correctly replace all missing protective shields, including any removal for servicing convenience. (2) When reinstalling the chassis and/or other assembly in the cabinet, be sure to put back in place all protective devices, including but not limited to nonmetallic control knobs, insulating fish-paper, adjustment and compartment covers shields, and isolation resistor/capacitor networks. Do not operate
this instrument or permit it to be operated without all protective devices correctly installed and functioning. Service technician who disregard safety features or fail to perform safety checks may be liable for any resulting damage.
b) Be sure that there are no cabinet openings through
which an adult or child might be able to insert their fingers and contact a hazardous voltage. Such openings include, but are not limited to (1) spacing between the picture tube and cabinet mask, (2) excessively wide cabinet ventilation slots, and (3) an improperly fitted and/or incorrectly secured cabinet back cover.
c) Antenna Cold Check - With the instrument AC plug
source, connect an electrical jumper across the two AC plug prongs. Place the instrument AC switch in the ON position. Connect one lead of an ammeter to the AC plug prongs tied together and touch the other ohmmeter lead to each tuner antenna input, exposed terminal screw and, if applicable, to the coaxial connector in sequence. If the measured resistance is less than 4.0 megohm or greater than
7.2 megohm, an abnormality exists that must be corrected before the instrument is returned to the customer. Repeat this test with the instrument AC switch in the OFF position.
d) Leakage Current Hot Check - With the instrument
completely reassembled, plug the AC line cord directly into a 220V outlet. (Do not use an isolation transformer during this test.) Use a leakage current tester or a metering system with the instrument AC switch first in the ON position and then in the OFF position, measure from a known earth ground (metal water-pipe, conduit, etc.), to all exposed metal parts of the instrument (antennas, handle bracket, metal cabinet, screw heads, metallic overlays, control shafts, etc.), especially any exposed metal parts that offer an electrical return path to the chassis. Any
current measured must not exceed 0.7 milliamps. Reverse the instrument power cord plug in the outlet and repeat test. (See the following connection diagram)
AC Leakage Test
ANY MEASUREMENTS NOT WITHIN THE LIMITS SPECIFIED HEREIN INDICATE A POTENTIAL SHOCK HAZARD THAT MUST BE ELIMINATED BEFORE RETURNING THE INSTRUMENT TO THE CUSTOMER OR BEFORE CONNECTING THE ANTENNA OR ACCESSORIES
e) High Voltage - This receiver is provided with a hold
down clearly indicating that voltage has increased in excess of a predetermined value. Comply with all notes described in this Service Manual regarding this hold down circuit when servicing, so that this hold down circuit may correctly be operated.
f) Service Warning - With maximum contrast,
operating high voltage in this receiver is lower than 32kV. In case if any component having influence on high voltage is replaced, confirm that the high voltage with maximum contrast is lower than 32kV. To measure H.V use a high impedance H.V. meter. Connect (-) to chassis earth and (+) to the CRT anode button. (See the following connection diagram).
Note: Must turn power switch off before the connection to the anode button is made.

SAFETY PRECAUTIONS
Fig. 1 X-ray shield plates
g) X-radiation (TUBE) -The primary source of
X-radiation in this receiver is the picture tube. The tube utilized for the above mentioned function in this chassis is specially constructed to limit X-radiation emissions.
For continued X-radiation protection, the replacement tube must be the same type as the original. HITACHI approved type. When troubleshooting and making test measurements in a receiver with a problem of excessive high voltage, avoid being unnecessarily close to the picture tube and the high voltage component.
Do not operate the chassis longer than is necessary to locate the cause of excessive voltage.
h) X-radiation Shield -This receiver is provided with
X-ray shield plates for protection against X-radiation. Do not remove X-ray shield plates A, B, C, or D shown in Fig.1 unnecessarily, when troubleshooting and/or making test measurements. To prevent X-radiation, after replacement of picture tube and lens, confirm these components to be fixed correctly to bracket and cabinet, and not to be taken off easily.

SAFETY PRECAUTIONS
2. Read and comply with all caution and safety-related notes on or inside the receiver cabinet, on the receiver chassis, or on the picture tube.
3. Design Alteration Warning - Do not alter or add to the mechanical or electrical design of this TV receiver. Design alterations and additions, including but not limited to circuit modifications and the addition of items such as auxiliary audio and/or video output connectors, might alter the safety characteristics of this receiver and create a hazard to the user. Any design alterations or additions may void the manufacturer’s warranty and may make you, the servicer, responsible for personal injury or property damage resulting therefrom.
4. Picture Tube Implosion Protection Warning - The picture tube in this receiver employs integral implosion protection. For continued implosion protection, replace the picture tube only with one of the same type number. Do not remove, install, or otherwise handle the picture tube in any manner without first putting on shatterproof goggles equipped with side shields. People not so equipped must be kept safely away while picture tubes are handled. Keep the picture tube away from your body. Do not handle the picture tube by its neck.
5. Hot Chassis Warning
a) Some TV receiver chassis are electrically connected
directly to one conductor of the AC power cord and may be safely serviced without an isolation transformer only if the AC power plug is inserted so that the chassis is connected to the ground side of the AC power source. Confirm that the AC power plug is inserted correctly with an AC voltmeter by measuring between the chassis and a known earth ground. If a voltage reading in excess of 1.0V is obtained, remove and reinsert the AC power plug in the opposite polarity and again measure the voltage potential between the chassis and a known earth ground.
b) Some TV receiver chassis normally have 85V AC
(RMS) between chassis and earth ground regardless of the AC plug polarity. These chassis can be safely serviced only with an isolation transformer inserted in the power line between the receiver and the AC power source, for both personnel and test equipment protection.
c) Some TV receiver chassis have a secondary ground
system in addition to the main chassis ground. This secondary ground system is not isolated from the AC power line. The two ground systems are electrically separated by insulating material that must not be defeated or altered.
6. Observe original lead dress. Take extra care to assure correct lead dress (the AC supply, high voltage and antenna wiring) in the following areas:
a) Near sharp edges b) Near thermally hot parts
Be sure that leads and components do not touch thermally hot parts. Always inspect in all areas for pinched, out-of -plate, or frayed wiring; Do not change spacing between components and the printed circuit board; Check AC power cord for damage.
7. Components, parts, and/or wiring that appear to have overheated or are otherwise damaged should be replaced with components, parts or wiring that meet original specifications. Additionally, determine the cause of overheating and/or damage and, if necessary, take corrective action to remove any potential safety hazard.
8. PRODUCT SAFETY NOTICE - Many TV electrical and mechanical parts have special safety-related characteristics some of which are often not evident from visual inspection, nor can the protection they give necessarily be obtained by replacing them with components rated for higher voltage, wattage, etc. Parts that have special safety characteristics are identified by a
! in the replacement parts list. Use of
substitute replacement that does not have the same safety characteristics as the recommended replacement part in the parts list might create shock, fire, and/or other hazards. Product safety is under review continuously and new instructions are issued whenever appropriate. For the latest information, always consult the appropriate current service literature. A subscription to, or additional copies of service literature may be obtained at a nominal charge from manufacturer.

LEAD FREE SOLDERING GUIDE
Lead free solder
With some exception, this product is going to use lead free solder (unleaded) to help preserve the
environment from the September of 2004. Please read these instructions before attempting any soldering
work.
Caution: Always wear safety glasses to prevent fumes or molten solder from getting into the eyes.
Lead free solder can splatter at high temperatures. (600ºC).
Lead free solder indicator
There is a F mark made behind the name of PWB or close to its on the printed circuit boards with lead free
solder.
Properties of lead free solder
The melting point of lead free solder is 40--50ºC higher than lead solder.
Servicing solder
Unleaded solder with an alloy composition of Sn-3.0Ag-0.5Cu is recommended. Although servicing with
leaded solder is possible, there are a few precautions that have to be taken. (Not taking these precautions
may cause the solder to not harden properly, and lead to consequent malfunctions.)
Precautions when using leaded solder
Remove all lead free solder from soldered dots when replacing components.
If leaded solder should be added to existing unleaded soldered dots , melt the leaded solder thoroughly
and mix it in the unleaded solder after the unleaded soldered dots have been completely melted. (It’s not
permitted to solder directly with soldering iron without solder)
Servicing soldering iron
A soldering iron with a temperature setting capability (temperature control function) is recommended. The
melting point of unleaded soldering tin is higher than that of leaded ones. Use a soldering iron that maintains
a high stable temperature (large heat capacity) and allows temperature adjustment according to the parts
awaiting serviced to avoid poor servicing performance.
Recommended soldering iron
Soldering iron with temperature control function (temperature range:320--450ºC)
Recommended temperature range per part:
PARTS Soldering iron temperature
Mounting (chips) on mounted PCB 320ºC±30ºC Mounting (chips) on empty PCB 380ºC±30ºC Chassis, metallic shield, etc. 420ºC±30ºC
