X-RADIATION WARNING The surface of pucture tube may generate X-Radiation. Precaution during servicing, and if possible use of a lead apron or metal for shielding is recommended. To avoid possible exposure to X-Radiation and electrical shock hazard, the high voltage compartment and the picture tube shield must be kept in place whenever the chassis is in operation.

1. Circuit description 1. 1 Power block 1.1.1 Outline The power block is compatible with the business electric power, 100 to 120VAC/220 to 240VAC (50/60Hz). The active filter circuit is adopted to suppress the higher harmonic current. The circuit block is composed of two switching regulators, the main power which is the configuration used the flyback converter system of pseudo resonance operation and the sub power which is the configuration used PWM (pulse wise modulation) system.
1.1.3 Sub power circuit When the power switch is turned ON, the rectified and smoothed DC voltage (AC voltage x √2) is supplied to pin 5 of IC903, and is charged to C930 through pin 1. When pin 1 reaches 5.7V, oscillation is started in IC903, and the built-in output FET is put into operation to add the pulse voltage between pin 5 and pin 3 on the primary side of T902.
1.2 Deflection processor block 1.2.1 Deflection processor (IC601) Deflection processor IC601 horizontally compensates wise, position and distortion, and vertically controls heights, position and linearity. IC601 automatically tracks the frequency to output the appropriate horizontal/vertical drive pulse. IC601 also outputs the horizontal parabola waveform for focus and the waveform for convergence compensation.
IC601 R652 VSAW-P R658 R648+R649 IC603 R645+R646 R650 VSAW-N R642 R647 IC603 R651 C628 IMID Q604 SW-VLIN1 R637 SW-VLIN2 Q603 Fig. 2 Vertical sawtooth waveform output circuit 1.2.4.2 Vertical output amplification circuit A current proportional to the waveform of the voltage input to IC401 will flow to the vertical deflection coil (V-DY).
1.2.6 DBF (Dynamic Beam Focus) circuit The horizontal/vertical DBF voltage is respectively generated and amplified, then synthesized at T7A1. As for the horizontal DBF voltage waveform, the parabola waveform voltage (approx. 0.5Vp-p) is output with IC601, and amplified about 10 times with OP-AMP IC6A2. After that, it is amplified to 50-60Vp-p with Q7B5 (the amplification factor is about 10 times), then it is amplified about 10 times with T7A1.

CRT. The CONSTANT BRIGHTNESS function, however, will recover the deteriorated brightness close to the initial level (level ensured at outgoing the factory). If the CONSTANT BRIGHTNESS function is activated, operation will be performed at 106kHz horizontally and at 85Hz vertically while ignoring the input signal, and the OSM-IC (IC212) will output the reference image signal.
program. 1.4.2.1 Corner purity circuit operation <TL: Upper left corner> Pin 50 (PWM_DAC) of IC102 controls the TL in the range of 0 to 5V while regarding 2.5V as the reference voltage, and the DC current of the above value will flow from pin 2 of IC803 to the upper left corner purity coil.
Examples of the functions and current waveform/compensation operation of YH (YHTT, THTB, YHJT, YHJB) are shown as follows. In the above formulas, b11T, b11B, b12T and b12B express the compensation coefficients, and y and y^2 express the primary and secondary functions of the vertical frequencies. The other parts except the compensation coefficients are programmed, and desired amplitudes (= compensation amount) are gained by varying the coefficients.

On each of 4H and 4V, the waveform added with the dynamic component and static component is input to IC8A1 pin 3 and pin 4, and it allows the specified current to flow to each convergence compensation coil.

1.5.6.2 High voltage data error detection Important safety data, such as the high voltage adjustment value and the X-ray protector activation voltage, are stored in the EEPROM. For each safety data, there is backup data. If both data values differ from each other, the monitor will enter the power saving mode (the high voltage will not be applied).
1.6 Safety protection circuit and X-ray protection circuit 1.6.1 X-ray protection circuit This circuit prevents X-ray radiation from exceeding the dangerous level due to the abnormal rise of high voltage. Do not modify the high voltage circuit and the safety protection circuit. The upper limit of the high voltage value and the beam current value are determined by the X-ray radiation upper limit curve of CRT.
