SAFETY PRECAUTIONS

SAFETY-RELATED COMPONENT WARNING!

X-RADIATION

There are special components used in this color monitor

which are important for safety. These parts are marked

on the schematic diagram and the replacement

parts list. It is essential that these critical parts should be

replaced with the manufacturer's specified parts to

prevent X-radiation, shock, fire, or other hazards. Do not

modify the original design without obtaining written

permission from manufacturer or you will void the original

parts and labor guarantee.

The only potential source of X-radiation is the picture tube.

However, when the high voltage circuitry is operating

properly there is no possibility of an X-radiation problem.

The basic precaution which must be exercised is keep the

high voltage at the factory recommended level; the normal

high voltage is about 25.5kV. The following steps describe

how to measure the high voltage and how to prevent X-

radiation.

Note : It is important to use an accurate high voltage

CAUTION: No modification of any circuit should be

attempted.

meter calibrated periodically.

Service work should be performed only after

you are thoroughly familiar with all of the

following safety checks and servicing

guidelines.

•

To measure the high voltage, use a high impedance

high voltage meter, connect (–) to chassis and (+) to

the CDT anode cap.

•

Set the brightness control to maximum point at full

white pattern.

SAFETY CHECK

Measure the high voltage. The high voltage meter

should be indicated at the factory recommended level.

If the meter indication exceeds the maximum level,

immediate service is required to prevent the possibility

of premature component failure.

Care should be taken while servicing this color monitor

because of the high voltage used in the deflection circuits.

These voltages are exposed in such areas as the

associated flyback and yoke circuits.

•

To prevent X-radiation possibility, it is essential to use

the specified picture tube.

FIRE & SHOCK HAZARD

An isolation transformer must be inserted between the

color monitor and AC power line before servicing the

chassis.

•

In servicing, attention must be paid to the original lead

dress specially 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.

All the protective devices must be reinstalled per the

original design.

CAUTION:

Please use only a plastic screwdriver to protect yourself

from shock hazard during service operation.

•

Soldering must be inspected for the cold solder joints,

frayed leads, damaged insulation, solder splashes, or

the sharp points. Be sure to remove all foreign

materials.

IMPLOSION PROTECTION

All used display tubes are equipped with an integral

implosion protection system, but care should be taken to

avoid damage and scratching during installation. Use only

same type display tubes.

1. Line Filter & Associated Circuit.

3) The Micom sets operating mode and offers the

controlled data. (H-size, H-position, V-size, ... etc.)

4) The controlled data of each mode is stored in itself.

5) User can adjust screen condition by each OSD

function. The data of the adjusted condition is stored

in EEPROM(IC402).

This is used for suppressing noise of power input line

flowing into the monitor and/or some noise generated in

this monitor flowing out through the power input line.

That is to say, this circuit prevents interference between

the monitor and other electric appliances.

2. Degauss Circuit & Coil.

7. Horizontal and Vertical Synchronous Processor.

The degauss circuit consists of the degaussing coil, the This circuit generates the horizontal drive pulse and the

PTC(Positive Temperature Coefficient) thermistor(TH901), vertical drive pulse by taking sync-signal from the Signal-

This circuit supplies DC voltage to the horizontal deflection

output circuit by increasing DC 50V which is the

secondary voltage of the SMPS in accordance with the

input horizontal sync signal.

3. SMPS(Switching Mode Power Supply).

This circuit is working of 90~264V AC(50/60Hz).

The operation procedure is as follows:

1) AC input voltage is rectified and smoothed by the bridge 9. Side-Pincushion & Trapezoid Correction Cirucit.

repeatedly.

4) Depending on turn ratio of the transformer, the

secondary voltages appear at the secondary coils of the

transformer(T901).

10. Horizontal Deflection Output Circuit.

This circuit makes the horizontal deflection by supplying

the saw-tooth current to the horizontal deflection yoke.

5) These secondary voltages are rectified by each

diode(D941, D942, D951, D961, D962, D971) and operate 11. High Voltage Output & FBT(Flyback Transformer).

wave to the primary coil of the FBT(Flyback Transformer) .

A boosted voltage(about 25.5KV) appears at the

secondary of the FBT and it is supplied to the anode of the

CDT. And there are another output voltages such as the

dynamic focus and the screen voltage(G2).

4. Display Power Management Circuit.

This circuit control power consumption of the monitor by

detecting H and V sync signal. There are off mode. When no

horizontal or vertical sync signal input, the circuit consists of

Q941 and Q951 becomes off mode. It’s power consumption

is below 5W.

12. H-Linearity Correction Circuit.

This circuit corrects the horizontal linearity for each

horizontal sync frequency.

5. X-ray Protection.

If the high voltage of the FBT reaches up to 29kV (abnormal

state), IC401(MICOM) pin 35 Sensing from FBT directly.

Then MICOM control IC701 (Deflection controller) to stop

Horizontal drive pulse and stop Horizontal Deflection.

13. Vertical Output Circuit.

This circuit takes the vertical ramp wave from the

TDA4857(IC701) and performs the vertical deflection by

supplying the saw-tooth current from the TDA4866(IC601)

to the vertical deflection yoke.

6. Micom(Microprocessor) Circuit.

14. Dynamic Focus Output Circuit.

The operating procedure of Micom(Microprocessor) and

its associated circuit is as follows:

This circuit takes the horizontal and the vertical parabola

waves from the TDA4857(IC701) and amplifies it to

maintain constant focus on center and corners in the

screen.

1) H and V sync signal is supplied from the signal cable.

2) The Micom(IC401) distinguishes polarity and

frequency of H and V sync.

15. H& V Blanking and Brightness Control.

18. Video Pre-Amp Circuit.

Blanking circuit eliminates retrace line by supplying

negative pulse to the G1 of the CRT. And Brightness

circuit is used for control of the screen brightness.

This circuit amplifies the analog video signal from 0-0.7V

to 0-4V. It is operated by taking the clamp, R, G, B drive

and contrast signal from the Micom(IC401).

16. Image Rotation (Tilt) Circuit.

19. Video Output Amp Circuit.

This circuit corrects the tilt of the screen by supplying the

image rotation signal to the tilt coil which is attached near

the deflection yoke of the CRT.

This circuit amplifies the video signal which comes from

the video pre-amp circuit and amplified it to applied the

CRT cathode.

17. OSD Circuit

This circuit is used for performing the OSD(On-Screen-

Display) function.

When a user selects the OSD Select/Adjustment control,

the adjustment status displays on the screen.
