DESCRIPTION OF BLOCK DIAGRAM

- 14 -

1. Line Filter & Associated Circuit.

This is used for suppressing noise of power input lineflowing into the monitor and/or some noise generatedin this monitor flowing out through the power input line.That is to say, this circuit prevents interferencebetween the monitor and other electric appliances.

2. Degauss Circuit & Coil.

The degauss circuit consists of the degaussing coil,the PTC (Positive Temperature Coefficient) thermistor(TH901), and the relay (RL901). This circuit eliminatesabnormal color of the screen automatically bydegaussing the slot mask in the CDT when turn on thepower switch.When you need to degauss while using the monitor,select DEGAUSS on the OSD menu.

3. SMPS (Switching Mode Power Supply).

This circuit works with power of 100~240V or200~240V (50/60Hz).

The operation procedure is as follows:

1) AC input voltage is rectified and smoothed by the bridge diode (D901) and the capacitor (C907).

2) The rectified voltage (DC voltage) is applied to the primary coil of the transformer (T901).

3) The control IC (IC901) generates switching pulse toturn on and off the primary coil of the transformer

(T901) repeatedly.

4) Depending on the turn ratio of the transformer, the secondary voltages appear at the secondary coil ofthe transformer (T901).

5) These secondary voltages are rectified by each diode (D906, D907, D908, D909, D910, D911,D912, D913) and operate the other circuits.(Deflection, Video Amplifier, etc.)

4. Display Power Management Circuit.

This circuit control power consumption of the monitorby detecting H and V sync signal. There are stand-byand suspend mode. When no horizontal or verticalsync signal input, the circuit consists of Q930 andQ907 becomes stand-by and suspend mode. It’spower consumption is below 8W. When no horizontaland vertical sync signal input, it’s power consumptionis below 3W.

5. X-ray Protection.

This circuit detects the rectified DC voltage comesfrom the FBT pin 4. If the high voltage of the FBTreaches up to about 30kV (abnormal state),Micom(IC401) detects. It stops B+ voltage supplied tothe FBT (T701), and high voltage is not be generated,(In the normal state, the high voltage is about 26kV.)

6. Micom(Microprocessor) Circuit.

The operating procedure of Micom (Microprocessor)and its associated circuit is as follows:

1) H and V sync signal is supplied from Signal Cable to theMicom (IC401).

2) The Micom (IC401) distinguishes polarity andfrequency of H and V sync.

3) The Micom controls each OSD function signals. (H-size, H-position, V-size, etc.)

4) The controlled data of each mode is stored in IC402.User can adjust screen condition by each OSDfunction. The data of the adjust screen condition isstored automatically.

7. Horizontal and Vertical Synchronous Processor.

This circuit generates the horizontal drive pulse andthe vertical drive pulse by taking sync-signal fromSignal Cable. This circuit consists of theTDA4856(IC701) and the associated circuit.

8. Oscillating Circuit for D/D Converter.

This circuit generates the pulse wave which has thehorizontal period by taking the output of the TDA4856(IC701).

9. D/D (DC to DC) Converter.

This circuit supplies DC voltage to the horizontaldeflection output circuit by decreasing DC 190V whichis the secondary voltage of the SMPS in accordancewith the input horizontal sync signal.

10. Side-Pincushion Correcting Cirucit.

This circuit improves the Side-pincushion of the screenby mixing east-west wave to the output of thehorizontal deflection D/D converter which is used forthe supply voltage source (B+) of the deflection circuit.

- 15 -

11. D/D Drive & Convert Circuit.

This circuit is used for supplying B+ voltage tohorizontal deflection output transistor (Q709). Thiscircuit makes to add side-pincushion correcting signalto B+ voltage.

12. Horizontal Deflection Output Circuit.

This circuit makes the horizontal deflection bysupplying the saw-tooth current to the horizontaldeflection yoke.

13. High Voltage Output & FBT (Flyback Transformer).

The high voltage output circuit is used for generatingpulse wave to the primary coil of the FBT (FlybackTransformer (T701)). A boosted voltage (about 26kV)appears at the secondary of the FBT and it is suppliedto the anode of the CDT.And there are another output voltages such as thedynamic focus voltage.

14. H-Linearity Correction Circuit.

This circuit corrects the horizontal linearity for eachhorizontal sync frequency.

15. Vertical Output Circuit.

This circuit takes the vertical wave from the TDA4856(IC701) and performs the vertical deflection bysupplying the saw-tooth wave current from theTDA8172 (IC601) to the vertical deflection yoke.

17. Dynamic Focus Output Circuit.

This circuit takes H and V parabola wave from theTDA4856 (IC701), and amplifies these waves to offerto the FBT (T701).

18. H & V Blanking and Brightness Control.

This circuit eliminates the retrace line by supplying anegative pulse to the G1 of the CDT. The brightnesscontrol circuit is used to control of the screenbrightness by changing the DC level of G1.

19. Image Rotation (Tilt) Circuit.

This circuit corrects the tilt of the screen by supplyingthe image rotation signal to the tilt coil which isattached to the CDT near the deflection.

20. Static Convergence Control Circuit.

This circuit corrects the convergence of the screen bysupplying the convergence signal to the 4H (STC) coilwhich is attached to the CDT near the deflection.

21. Moire Reduction Circuit

This circuit reduce interference between the periodicaldisplay pattern and the CDT's slot (or dot).The positions of every other one dot video signalbeams (red, green, and blue beam) are shifted finely,thus reducing interference.

22. OSD Circuit.

This circuit is used for performing the OSD (On-Screen- Display) function.When a user selects the OSD Select/Adjustmentcontrol, the adjustment status displays on the screen.

23. Video Pre-Amp Circuit.

This circuit amplifies the analog video signal from 0-0.7V to 0-4V. This circuit is operated by taking theclamp, R, G, B drives, and contrast signals from theMicom (IC401).

24. Video Output Amp Circuit.

This circuit amplifies the video signal which comesfrom the video pre-amp circuit and amplified videosignal is applied to the CDT cathode.
