1. Precautions And Safety Notices

WARNING!

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.

ViewSonic Corporation Confidential – Do Not Copy E70f-5_E70fB-5_E70fSB-5

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.

Note： 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

WARNING：The 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.

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

4. Circuit Description

4-1 MICRO CONTROLLER CIRCUIT

MICRO Controller

The IC101 contains a 8031 8-bit CPU core, 60K bytes of RAM, 16K bytes of ROM,14 channel 8 bit PWM D/A converters, 2 channel A/D converters for key detection,0.5sec watch-dog timer, internal H-sync and V-sync signals processor providing mode detection, watch- dog timer preventing system from abnormal operation, and an I²C bus interface.

H/V sync signals processor

The functions of the sync processor include polarity detection, H-SYNC & V-SYNC signals counting, Programmable SYNC signals output, free running signal generator. Pin41/Pin42 are for the H-SYNC and VSYNC input, Pin34/Pin33 will output the same signal as input sync signal without delay, and the polarity are setting in the positive. When no signal input, the Pin32 will output a 60Hz V-SYNC free run signal. The Pin33 will output a 48KHz H-SYNC free run signal. for the monitor testing use.

On Screen Display Controller

The IC801 is designed for display the built-in characters or fonts onto monitor screen. The display operation is by transforming data and control information from micro controller to RAM through a serial data interface. Pin2 is used to control the internal oscillator frequency by DC voltage input from external low pass filter (R154, C166, R155) and filter (R175, C167) is used to regulate the appropriate bias current for internal oscillator the resonate at specific dot frequency. Pin5 is input the horizontal fly back pulse, for PLL generator tracking. Pin6 is left floating, I²C bus is enabled. Otherwise the SPI bus is enabled. Pin7 the external data transfer through this pin to internal display registers and control registers Pin8 the clock-input pin is used to synchronize the data transfer. Pin10 is input the vertical flyback pulse for synchronizing the vertical position. Pin12 is output a blanking signal to cut off external R.G.B signals of VGA while this chip is displaying characters or windows. Pin13, Pin14, Pin15 is used to output the OSD (B.G.R) video signal.

ViewSonic Corporation Confidential – Do Not Copy E70f-5_E70fB-5_E70fSB-5

4-2 DEFLECTION CIRCUIT

The deflection circuit is achieved by a high performance and efficient solution IC 401 (TDA4841) for this monitor. The concept is fully DC controllable and can be used in applications with a micro-controller solutions. The TDA4841 provides sync. Processing with full auto sync. Capability, a flexible SMPS block and an extensive set of geometry control facilities. Further the IC generates the drive waveforms for DC coupled vertical boosters to the TDA4863.

Horizontal Oscillator

The oscillator is of the relaxation type and requires a capacitor of 1nF C403 at pin29.

PLL 1 Phase Detector

The phase detector is a standard one using switched current sources. It compares the middle of H-sync. with a fixed point on the oscillator saw-tooth voltage. The PLL loop filter C401, C402, R409 is connected to Pin26.

PLL2 Phase Detector

The PLL2 detector thus compensates for the delay in the external H-deflection circuit by adjusting the phase of the HDRV output pulses. The phase between H-flyback and H-sync can be controlled at pin30.

X-ray Protection

The X-ray protection input pin2 provides a voltage detector with a precise threshold. If the voltage exceeds this threshold for a certain time, an internal latch switches the whole IC into protection mode. In this mode several pins are forced into defined states: Pin6 (BDRV) is floating Pin8 (HDRV) is floating Pin12, 13 ( VOUT 12, 13) are floating

Vertical Oscillator

The vertical free –running frequency is determined by the resistor C613 at pin24. Usually the free-running frequency should be lower than the minimum trigger frequency.

obtain a complete field of the color red. This is done by moving the two tabs in such a manner that they advance in an opposite direction but at the same time to obtain the same angle between the two tabs, which should be approximately 180'.

D. Check the complete blue and complete green patterns to observe their respective color purity. Make minor

adjustments if needed.

6. Convergence adjustment A. Produce a magenta crosshatch on the display.

B. Adjust the focus for the best overall focus on the display.

Also adjust the brightness to the desired condition.

C. Vertical red and blue lines are converged by varying the angle between the two tabs of the 4 pole magnets

on the PCM assembly. (See above diagrams)

D. Horizontal red and blue lines are converged by varying the two tabs together, keeping the angle between

them constant.

E. Produce a white crosshatch pattern on the display. F. Vertical green and magenta lines are converged by varying the angle between the two tabs of the 6-pole

magnets.

G. Horizontal green and magenta lines are converged by varying the two tabs together, keeping the angle

between them constant.
