DESCRIPTION OF BLOCK DIAGRAM
1. Line Filter 3. Associated Circuit.
This Is used for suppressing noise of power input line
flowing into the monitor andlor 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 8. Coil.
The degauss circuit consists of the degaussing coll, the
PTc(Posttive Temperature Coefficient) thermistor(TH901),
and the ralay(RL901). This circuit eliminates abnormal
color of the screen automatically by degaussing the
shadow mask In the CRT during turning on the power
switch. When you need to degauss in using the monitor,
sated DEGAUSS on the OSD menu.
3. sMFSlswitching Mode Power Supply).
This circuit is working of 90~264V AClsO/GOHZ).
The operation procedure is as iollows:
1) AC Input voltage is rectified and smoothed by the
bridge diodes (0900) and the capacitor (C903).
2) The rectified vollage(DC) is applied to the primary
coil of the transtonner(T901).
3) The control IC(I0901) generates switching pulse to
turn on and oft the primary coil of the transtormer
(7901) repeatedly.
4) Depending on turn ratio of the transtormer. the
secondary voltages appear at the secondary coils of
the transforrner(T901).
5) These secondary voltages are rectified try each
dlode(D941. D942. D951. 0961, D962. D971) and
operate other circuit. (horizoriiai and vertical defledion.
video amplifier. ...etc.)
4. X-ray Protection.
IfthshigtvoliagedtheFBTreedtesuptoZSthbrmnal
state), 0807 operates and IO401(MIOOM) pin 41 come to
low level. Then MICOM control IC701 (Ddiedion controller)
to stop Horizontal drive pulse and slap Horizontal Defledlon.
5. MIoorMMIcropromsor) circuit
The operating procedure of MioorrKMicroprocessor) and its
associated circuit is as follows:
1) H and V sync signal Is supplied from the signal cable.
2) The Micom(lc401) distinguishes polarity and
frequency of H and V sync.
3) The Micom sets operating mode and offers the
controlled data. (H—size, H-position, V—slze, etc.)
4) The controlled data of each mode is stored in itself.
5) User can adjust screen condition by each 030
lunction. The data of the adjusted condition is stored
in EEPROM(IC402).
6. Horizontal and Vertical Oscillation
This circuit generates the horizontal pulse and the vertical
pulse by taking the H and V sync signal.
This circuit consists of the TDA4841(lC701) and the
associated circuit.
7. DIDch to Dc) Converter.
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.
8. Horizontal Deflection Output Circuit.
This circuit makes the horizontal deflection by supplying
the saw-tooth current to the horizontal deflection yoke.
9. High Voltage Output a. FBT(Fbeack Transtormer).
The high voltage output circuit is used tor generating pulse
to the primary coil of the FBT(Fbeack Transformer
(1700). A boosted voltage(about 25.5kV) appears at the
secondary oi the PET and it Is supplied to the anode.
locus, and screen voltage of the CRT.
10. Iii-Linearity carnelian circuit.
This circuit corrects the horizontal linearity for each
horizontal sync frequency.
11. Vertical Output Circuit.
This circuit inputs the vertical ramp were from the
IC701(TDM841) to the ICEOtUDMBsG) and amplifies.
supplies the saw-tooth current to the vertical deflection
yokeN-DY).
12. H&V Blanking and Brightness Control.
Blanking clrcull eliminates retrace line by supplying
negative pulse to the G1 of the CRT. And Brightness
circuit is used tor control of the screen brightness by
changing DC level at the G1.
13. Image Rotation (Tilt) Circuit.
This circuit corrects the tilt of the screen by supplying the
Image rotation signal to the tilt coil which is evadred near
the deflection yoke of the CRT.
.11.
14. Video Pro-Amp Circuit 15. Video Output Amp Circuit
This circuil amplifies the analog video slgnal from 00.7V This circuit amplifies ihe video signal which comes from
to 04V. It is operated by taking ihe clamp, R. G. B drive Ihe video pre—amp circuit and amplified It in applied me
and oonirast signal from the Mioom(IC401)4 CRT calhode.
