SELF DIAGNOSIS FUNCTION This monitor has SELF DIAGNOSIS function as below table, when turn on monitor, please check LED blink times. 12.1 X-ray Protector Operate On this condition, please check around T301 (FBT). U701 detect pin 3. Normally this pin is low level. When operate X-ray circuit, U701 pin 3 become high level.

1. Power Supply Circuit 1.1 Outline This power supply unit adopts the switching mode technology, and is an off-line mode type unit that provided several different DC outputs. The scanning frequency is available in different values ranging from 31 kHz to 110 kHz.
Page 120
2) The power supply MOS FET Q101 carries out the ON/OFF operation of the control unit, by means of U101 KA3842A. KA3842A is a PWM (pulse width modulation) IC chip, with 16 V starting voltage and 10 V cut-off voltage. The following list shows the pin layout of KA3842A pulse width modulation IC chip.
1.7 Power saving Suspend mode : Every DC voltage operation of the CRT is reduce to 2 Volt. OFF mode : The color of the power LED101 switches from green to orange. 1) When the power switch is turned ON when there is nothing being entered in the video cable. At that time, if the video is shifted from the free-run mode to the suspend mode, the transistor Q151 turns OFF and the operation returns to the OFF mode within a few seconds.
2. Video Circuit & OSD The video amplifier system is consist of the Pre-Amplifier, the Video-Power-Amplifier, and the cutoff-Voltage circuit. a) The U201 (LM1267) is a three channel video pre-amplifier IC, that controlled by MCU IIC bus for the features of contrast, output DC level, 3 SUB gain controls (R-Gain, G-Gain, B-Gain). b) U201 PIN 23 need a positive pulse for clamping and PIN 24 also need a positive pulse for blanking.
5. Horizontal Deflection a) U501 is a horizontal signal processing IC. Horizontal Driver signal is output from pin 8 of U501 TDA4856 and through Q506, Q507 to drive Q313 and T304. b) T304 is an on/off type driver transformer. It functions to convert primary energy to secondary, and drive the horizontal output transistor Q314.
7. Dynamic Focus a) H-Focus: T302 is H-Dynamic Focus amplified. b) V-Focus: U501 pin 32 output waveform through R356 and C343 to get a parabolic waveform. This waveform is amplified by Q312 and input into T302. c) H-Focus and V-Focus are into T302 to get a combined waveform that will input to FBT. 8.
