2. PRECAUTIONS AND NOTICES

2-1 SAFETY PRECAUTIONS

1. Observe all caution and safety related notes located inside the display cabinet.

2. Operation of the display with the cover removed, may cause a serious shock hazard from the display
power supply. Work on the display should not be attempted by anyone who is not thoroughly
familiar with precautions necessary when working on high voltage equipment.

3. Do not install, remove or handle the picture tube in any manner unless shatter-proof goggles are
worn. People who are not so equipped should be kept away while handling picture tube. Keep
picture tube away from the body while handling.

4. The picture tube is constructed to limit X-RAY radiation to 0.5 mR/HR. For continued protection,

use the designated replacement tube only, and adjust the voltages so that the designated maximum
rating at the anode will not be exceeded.

5. Symbol “ ” means safety relative parts. The use of substitute replacement parts which do not have

the same characteristics as specified in the parts list may create shock, fire or explode etc.

6. Symbol “Ϫ“ means X-ray relative parts. Before replacing any of these components please read the

parts list in this manual carefully to avoid creating higher anode voltage or x-ray. Especially for
sealed controls, such as VR901, VR902, VR401 and FBT screen VR etc, which were sealed by the
manufacturer once their optimum position has been set, please don’t dismantle them as your likes,
otherwise you will break or damage the component. If you need replace the parts with sealed control,
please adjust the relative VR to make sure the B+ voltage under 61.0V
glue or equivalent, which you can not move away with one screw driver

7. Before returning a serviced display to the customer, a thorough safety test must be performed to
verify that the display is safe to operate without danger or shock. Always perform an AC leakage
current check on the exposed metallic parts of the cabinet, such as screw heads.
Test method for current leakage is described as follow.
(a) Plug the AC line cord directly into rated AC outlet (do not use a line isolation transformer

during this check).

(b) Use an AC voltmeter having 5000 ohms per volt or with more sensitivity in the following

manner: Connect a 1500 ohms 10 Watt resistor, paralleled by a 0.15UF, AC type capacitor
between a known good earth ground (water pipe, conduit, etc.) and the exposed metallic parts
simultaneously. Measure the AC voltage across the combination of 1500 ohms resistor and

0.15UF capacitor.

(c) Reverse the AC plug at the AC outlet and repeat AC voltage measurements for each exposed

metallic part.

(d) Voltage measured must not exceed 0.5 volts RMS. This corresponds to 0.35 milliamp AC. Any

value exceeding this limit constitutes a potential shock hazard and must be corrected
immediately.

DC and well seal it with A+B

2-2 PRODUCT SAFETY NOTICE

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, X-RAY radiation or other hazards.

2-3 SERVICE NOTES

1. When replacing parts or circuit boards, clamp the lead wires around terminals before soldering.

2. When replacing a high wattage resistor (more than 1/2W of metal oxide film resistor) in circuit
board, keep the 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.

2-4 HIGH VOLTAGE WARNING

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

25.0KV ± 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.

5-2 DEFLECTION CIRCUIT

The deflection circuit is achieved by a high performance and efficient solution IC 401 (TDA9116) for this
monitor. The concept is fully DC controllable and can be used in applications with a micro-controller
solutions.
The TDA9116 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 C409 at pin6. The free running
frequency is determined by a resistor R412 5.1K form pin8 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 is connected
to Pin9.

PLL2 Phase Detector

This phase detector is similar to the PLL1 detector and compares the line flyback pulse at pin 12 with the
oscillator saw-tooth 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 pin5.

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 –running frequency is determined by the resistor C613, C616, R616 at pin22. Usually the
free-running frequency should be lower than the minimum trigger frequency.
