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. Precautions And Safety Noticess

ViewSonic Corporation Confidential -Do Not Copy 70f+SB-3 E

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.

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

on the schematic

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.

2. OPERATING TEMPERATURE RANGE IS 0

C TO 40oC WITH A RELATIVE HUMIDITY OF 10% OR LESS TO 90%.

3. THE MONITOR MUST BE OPERATIONAL IN AN USABLE STATE WITHIN 30 SECONDS AFTER TURN-ON.

4. ALL SIGNAL LEVELS ARE MEASURED ASSUMING TERMINATION AT THE MONITOR'S INPUT JACKS OR IN ITS CHARACTERISTIC IMPEDANCE.

AN AMBIENT LIGHTING LEVEL OF 400 TO 600 LUX IS ASSUMED WHEN SETTING BRIGHTNESS FOR RASTER EXTINCTION THRESHOLD.

6. ALL PURITY RELATED SPECIFICATIONS MUST BE MET WITHOUT EXTERNAL DEGAUSSING.

7. ALL CONTROLS MUST HAVE EXCESS RANGE (NO CONTROL MAY BE LEFT AT AN END STOP WHEN PROPER ALIGNMENT IS COMPLETED).

THE MONITOR IS NOT REQUIRED TO MEET SPECS DURING THE FOLLOWING BUT MUST TOLERATE, WITHOUT

DAMAGE TO THE CRT OR CIRCUITS, ANY SEQUENCY OR COMBINATION OF POWER ON AND OFF, SIGNAL ON AND OFF, ERRATIC, WRONG FREQUENCY OR NOISY INPUTS WHILE AT ANY POSSIBLE UNPLUGGING OF POWER

OR SIGNAL, SETTINGS OF USER ACCESSIBLE CONTROLS. LIKEWISE, THE MONITOR SHOULD SURVIVE EXTENDED PERIODS OF OPERATION WITH LINE VOLTAGE REDUCED BELOW THE SPECIFIED MINIMUM.

9. AN ISOLATION TRANSFORMER SHOULD BE USED WHEN PERFORMING ALIGNMENT AND TESTS. PORTIONS OF THE POWER SUPPLY BOARD ARE HOT GROUND. THE REMAINING BOARDS ARE COLD GROUND.

10. DISCHARGE OF CRT ANODE SHOULD BE DONE ONLY TO CRT GROUND STRAP.
