1. Precautions And Safety Noticess

WA RN I N G!

This service information is designed for experience repair technicians only and is not designed for use by the general public.

It does not contain warnings or cautions to advise non-technical individuals of potential dangers in attempting to service

a product.

Products powered by electricity should be serviced or repaired only by experienced professional technicians.

Any attempt to service or repair the product or products dealt within this service information by anyone else

could result in serious injury or death.

1. CAUTION

No modification of any circuit should be attempted. Service work should only be performed after you are thoroughly

familiar with all of the following safety checks and servicing guide lines.

2. SAFETY CHECK

Care should be taken while servicing this CRT display because of the high voltage used in the deflection circuits.

These voltages are exposed in such areas as the associated flyback and yoke circuits.

3. FIRE & SHOCK HAZARD

3-1 Insert an isolation transformer between the CRT display and AC power line before servicing the chassis.

3-2 In servicing pay attention to original lead dress especially in the high voltage circuit. If a short circuit is found,

replace all parts which have been overheated as a result of the short circuit

3-3 All the protective devices munt be reinstalled per original design.

3-4 Soldering must be inspected for possible cold solder joints, frayed leads, damaged insulation, solder splashes or

sharp solder points. Be certain to remove all foreign material.

4. LEAKAGE CURRENT COLD CHECK

4-1 Unplug the AC cord and connect a jumper between the two prongs on the plug.

4-2 Turn the CRT display power switch “on”.

4-3 Measure the resistance value with an ohmmeter between the jumpered AC plug and each exposed metallic part

on the CRT display such as the metal frame, screwheads, control shafts, etc. When the exposed metallic part has

a return path to the chassis, the reading should be 1.8 megohm minimum

.

.

5. LEAKAGE CURRENT HOT CHECK

5-1 Plug the AC cord directly into the AC outlet. Do not use an isolation transformer during this check.

5-2 Connect a 1500 ohm, 10 watt resistor, paralleled by a 0.15uF capacitor between each exposed metallic part and

a good earth ground (as shown in Fig.1).

5-3 Use an AC voltmeter with 1000 ohm/volt or more sensitivity and measure the AC voltage across the

combination 1500 ohm resistor and 0.15uF capacitor.

1

5-4 Move the resistor connection to each exposed metallic part and measure the voltage.

5-5 Reverse the polarity of the AC plug in the AC outlet and repeat the above measurement.

5-6 Voltage measured must not exceed 7.5 volt RMS, from any exposed metallic part to ground A leakage current

tester may be used in the above hot check, in which case any current measured must not exceed 5.0 milliamp. In

the case of a measurement exceeding the 5.0 milliamp value, a rework is required to eliminate the chance of

shock hazard.

NoteΚ High voltage is present when this CRT display is operating. Always discharge the anode of the picture

tube to the display chassis to prevent shock hazard.

6. IMPLOSION PROTECTION

Picture tubes are equipped with an integral implosion protection system, but care should be taken to avoid damage and

scratching during installation. Use only Panasonic replacement picture tubes.

7. X-RADIATION

WA RN I NG ΚThe only potential source of X-Radiation is the picture tube. However when the high voltage circuit is

operating properly there is no possibility of X-Radiation problem. The basic precaution which must be exercised is to

keep the high voltage at the following factory-recommended level.

NoteΚΚΚΚ It is important to use an accurate periodically calibrated high voltage meter.

GROUND)

0.15ӴF

1500 Ө 10W

Fig. 1

7-1 The procedure for adjusting high voltage is shown on page 27.

7-2 If can not be adjust 25.0 KV at immediate service is required to prevent the possibility of premature

component failure.

7-3 To prevent X-Radiation possibility it is essential to use the specified picture tube.

IMPORTANT SAFETY NOTICE

There are special components used in this CRT displays

which are important for safety. These parts are identified

by the international symbol

diagram and on the replacement parts list. It is essential

that these critical parts should be replaced with

manufacture’s specified parts to prevent X-RADIATION,

shock, fire, or other hazards. Do not modify the original

design or this will void the original parts and labor

guarantee.
