DESCRIPTION OF BLOCK DIAGRAM
1. Line Filter & Associated Circuit.
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.
The degauss circuit consists of the degaussing coil, the PTC (Positive Temperature Coefficient) thermistor (TH901), and the relay (RL901). This circuit eliminates abnormal color of the screen automatically by degaussing the slot mask in the CDT when turn on the power 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 or 200~240V (50/60Hz) specially for PFC version. The operation procedure is as follows:
4. Display Power Management Circuit.
This circuit control power consumption of the monitor by detecting H and V sync signal. There are stand-by and suspend mode. When no horizontal or vertical sync signal input, the circuit consists of Q913, Q and IC401 control signal becomes stand-by and suspend mode. It’s power consumption is below 8W.
5. X-ray Protection. This circuit detects the rectified DC voltage comes from the FBT pin 4. If the high voltage of the FBT reaches up to about 30kV (abnormal state), H.V control (IC802) detects. It stops B+ voltage supplied to the 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:
ADJUSTMENT
All adjustment are thoroughly checked and corrected when the monitor leaves the factory, but sometimes several adjustments may be required. Adjustment should be following procedure and after warming up for a minimum of 30 minutes.
AUTOMATIC AND MANUAL DEGAUSSING The degaussing coil is mounted around the CDT so that automatic degaussing when turn on the monitor. But a monitor is moved or faced in a different direction, become poor color purity cause of CDT magnetized, then press DEGAUSSING on the OSD menu.
- Install the cable for adjustment such as Figure 1and run the alignment program on the DOS for IBM compatible PC. - Set external Brightness and Contrast volume to max position. 1. Adjustment for B +^ Voltage.
2. Adjustment for High-Voltage.
3. Adjustment for Horizontal Raster Center.
4. Adjustment for Factory Mode (Preset Mode).
Display cross hatch pattern at Mode 1~4.
Run alignment program for F700PJ on the IBM compatible PC.

Display from Mode 4 and repeat above from number 6) to 15).
COMMAND → PRESET EXIT → Y (Yes) command.
5. Adjustment for White Balance and Luminance. 1) Set the White Balance Meter. 2) Press the DEGAUSSING on the OSD menu for demagnetization of the CDT. 3) Display color 0,0 pattern at Mode 4. 4) COMMAND → PRESET START → Y(Yes) command. 5) Set Bightness and Contrast to max position. 6) COLOR ADJ. → LUMINANCE command of the alignment program. 7) COLOR ADJ. → BIAS ADJ. command of the alignment program. 8) Check whether blue color or not at R-BIAS and G- BIAS to min position, Sub-Brightness to 90 position, B-BIAS to 75 or 100 ( 75 : when CDT is M41QBF423X07(P), 100 : when CDT is M41QEV423X01(CH)) position. If it's not blue color, the monitor must repair. 9) Adjust Screen control on the FBT to 0.15 ± 0.05FL of the raster luminance. 10) Adjust R-BIAS and G-BIAS command to x=0.283 ± 0.006 and y=0.298 ± 0.006 on the White Balance Meter with PC arrow keys.
6. Adjustment for Focus. 1) Display H character in full screen at Mode 4. 2) Adjust two Focus control on the FBT that focus should be the best condition.
