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. Confidential - Do Not Copy ViewSonic Corporation 1 E70-11 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. AC VOLTMETER (EARTH GROUND) TO INSTRUMENT'S EXPOSED METAL PARTS 0.15μF 1500 Ω 10W Fig. 1 6.

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. 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. Confidential - Do Not Copy ViewSonic Corporation 10 E70-11 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. 4-3 TRANSISTOR & DIODE CIRCUIT LOCATION CIRCUIT FUNCTION DESCRIPTION D901 ~ D904 Bridge Rectifier for AC Source D910 Clamp Diode for Snubber CKT D918, D919 Rectifier for Output Voltage D922 Rectifier for Output Voltage D923 Rectifier for Output Voltage D925 Rectifier for B+ Supply Q901 MOS FET for Switching Power Control.
