SAFTY PRECAUTIONS

WARNING: The following precautions should be opserved.

1.Do not install , remove, or handle the picture tube in any manner unless shatter proof goggles are worn. People not so equipped should be kept away while picture tubes are handled. Keep picture tube away from the body while handing.

2.

When

service is required, an isolation

transformer

 

should

be

inserted between

power

line and the

 

receiver before

any

service

is performed on the

 

chassis.

 

 

 

 

 

3.

When

replacing

the

chassis

in the cabinet,ensure

 

all

the protective devices are put back in place,such

 

as

barriers,

non - metallic knobs, adjustment or

compartment covers or shields, isolation resistors/ capacitors, etc.

4. When service is required, observe the original lead dressing. Extra precaution should be taken to

assure correct lead dressing in the high voltage circuitry area. Particularly note the R. G. B. lead dressing. Ensure they are dressed well away from the horizontal scan and F.B.T. circuitry.

5. Always use the manufacturer ' s replacement component. Always replace original spacers and maintain lead lengths. Especially critical components are indicated thus on the parts list and should not be replaced by other makes. Furthermore, where a short circuit has occurred, replace those components that indicate evidence of overheating.

6.Before returning a serviced receiver 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 instrucment by the manufacturer has became defective, or inadvertenly damaged during servicing. Therefore, the following checks are recommended for the continued protection of the customers and service techninians.

INSULATION

Insulation resistantce should not be less than 4.5 Mohm at 500 VDC between the mains poles and any accessible metal parts. Also, no flashover or breakdown should occur during the dielectric strength test, applying 3.2kV AC for two seconds between the main poles and accessible metal parts.

HIGH VOLTAGE

High voltage should always be kept at the rated value of the chassis and no higher. Operating at higher voltages may cause a failure of the picture tube or high voltage supply, and also, under certain circumstances could produce X-radiation moderately in excess of design levels. The high voltage must not, under any circumstances, exceed 34kV on the chassis.

X-RADIATION

TUBES : 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 - radiatuion.

For continued X-radiation protection, replace tube with the same type as the original, HITACHI approved type.

PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in HITACHI television receiver have special safety related characteristics. These characteristics are often not evident from visual inspection, nor can be protection afforded by them necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified by marking with a on the schematics and replacement 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 electrical shock, fire, X - radiation,

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 of HITACHI Service Manuals may be obtained at a nominal charge from your HITACHI sales offices.

TUBE DISCHARGE

The line output stage can develop voltages in excess of 25 kV; if the E.H.T cap is required to be removed, discharge the anode cap to chassis via a high value resistor, prior to its removal from the tube.
