Many electrical and mechanical parts in this chassis have special safety visual inspections and the protection afforded
by them cannot necessarily be obtained by using replacement components rated for higher voltage, wattage, etc.
Before replacing any of these components read the parts list in this manual carefully. The use of substitute
replacement parts which do not have the same safety characteristics as specified in the parts list may create shock, fire,
When replacing a high wattage resistor (more than 1/2W of metal oxide film resistor) in circuit board, keep the

2-3 SERVICE NOTES
1. When replacing parts or circuit boards, clamp the lead wires around terminals before soldering.
2. resistor about 10mm (1/2 in) away from circuit board.
3. Keep wires away from high voltage or high temperature components.
4.
Keep wires in their original position so as to reduce interference.
Page 6
Operation of monitor outside of cabinet or with back removed may cause a serious shock hazard. Work on this model
should only be performed by those who are thoroughly familiar with precautions necessary when working on high
voltage equipment.
Exercise care when servicing this chassis with power applied. Many B plus and high voltage terminals are exposed
which, if carelessly contacted, can cause serious shock or result in damage to the chassis. Maintain interconnecting
ground lead connections between chassis and picture tube dag when operating chassis. Certain HV failures can increase X-
ray radiation. Monitor should not be operated with HV levels exceeding the
specified rating for the chassis type. The maximum operating HV specified for the chassis used in this monitor is
25KV ¡Ó 1KV
with a line voltage of 120/240 VAC. Higher voltage may also increase possibility of failure in HV supply.
It is important to maintain specified values of all components in the horizontal and high voltage circuits and anywhere
else in the monitor that could cause a rise in high voltage or operating supply voltages. No changes should be made to
the original design of the monitor. Components shown in the shaded areas on the schematic should be replaced with
exact factory replacement parts. The use of unauthorized substitute parts may create a shock, fire or other hazard.
To determine the presence of high voltage, use accurate, high impedance, HV meter connected between second anode
lead and CRT dag grounding device. When servicing the High Voltage System, remove static charge from it by
connecting a 10K ohm resistor in series with an insulated wire (such as a test probe) between picture tube dag and 2nd
anode lead.(AC line cord disconnected from AC power outlet.)
The picture tube used in this monitor employs integral implosion protection. Replace with tube of the same type
number for continue safety. Do not lift picture tube by the neck. Handle the picture tube only after discharging the
high voltage completely.

3. OPERATING INSTRUCTIONS
This procedure gives you instructions for installing and using the Color display.
1. Position the display on the desired operation and plug the power cord into a convenient AC outlet. Three-
wire
power cord must be shielded and is provided as a safety precaution as it connects the chassis and cabinet to the
electrical conduit ground. If the AC outlet in your location does not have provisions for the grounded type plug,
the installer should attach the proper adapter to ensure a safe ground potential.
2. Connect the 15-
pin color display shielded signal cable to your signal system device and lock both screws on the
connector to ensure firm grounding. The connector information is as follow:
15 - Pin Color Display Signal Cable
3.
Apply power to the display by turning the power switch to the "ON" position and allow about thirty seconds for
display tube warm-up. The Power-On indicator lights when the display is on.
4.
With proper signals feed to the display, a pattern or data should appear on the screen, adjust the brightness and
contrast to the most pleasing display.
5.
This monitor has power saving function following the VESA DPMS. Be sure to connect the signal cable to the
PC.
6. If your color display requires service, it must be returned with the power cord.

5. CIRCUIT DESCRIPTION
5-1 MICRO CONTROLLER CIRCUIT
MICRO Controller
The IC101 contains a 6502 8-bit CPU core, 512 bytes of RAM, 16K bytes of ROM,14 channel
8 bit PWM D/A
converters, 2 channel A/D converters for key detection, one 8 bit pre-loadable base timer, internal H-sync and V-
sync
signals processor providing mode detection, watch- dog timer preventing system from abnormal operation, and an I²
C
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. Pin39/Pin40 are for the H-SYNC and V-
SYNC input, Pin32/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 61Hz V-SYNC free run signal. The Pin33 will output a 62.5KHz H-
SYNC free run signal.
for the monitor testing use.
On Screen Display Controller
The IC105 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.
Page

Page 14
5-2 DEFLECTION CIRCUIT
The deflection circuit is achieved by a high performance and efficient solution IC 401 (TDA9111) for this monitor. The
concept is fully DC controllable and can be used in applications with a micro-controller solutions.
The TDA9111 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
TDA9302H.
Horizontal Oscillator
The oscillator is of the relaxation type and requires a capacitor of 1nF C447 at pin5. The free running
frequency is
determined by a resistor R410 4.7K form pin6 to ground.
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 C435, C437, R411, D403 is connected to Pin7.
PLL2 Phase Detector
This phase detector is similar to the PLL1 detector and compares the line flyback pulse at pin 12 with the oscillator saw­tooth voltage. 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 pin4.
X-ray Protection
The X-
ray protection input pin25 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: Pin28 (BDRV) is floating Pin26 (HDRV) is floating Pin21, 23 ( VOUT 1, 2) are floating
Vertical Oscillator
The vertical free ¡Vrunning frequency is determined by the resistor C613, C616, R616 at pin22. Usually the free­running frequency should be lower than the minimum trigger frequency.
