6.6.6.6. CIRCUIT DESCRIPTIONCIRCUIT DESCRIPTIONCIRCUIT DESCRIPTIONCIRCUIT DESCRIPTION

6.1 Switching Mode Power Supply (SMPS)The switching mode power supply for this monitor is a full range type. Universal power input of ac100V ~ 240V is compatible. The AC input is supplied through the slow blow fuse F801, the first linefitter T802, the second line filter T803 to the rectifier D811 ~D814. The rectified DC voltage is about125V ~ 335V and is fed to the switching transformer T801 via R808.Prior to start, small current flows to C866A via R849, R850, Q850. I862 is to operate immediately whenthe voltage across C866A reaches 16V. At the same time, Q868 is on, the rectified current flows throughthe primary winding of T801 and the energy is stored in it. When Q868 is off, the energy is transferredto the secondary winding, the auxiliary winding is close -coupled and in phase with the secondarywinding, it will provide a holding voltage on C866A and fed to pin 7 of I862 via R831, D831, D870I862 will keep working provided that voltage across C866A is over 10V.The oscillating frequency of the switching mode power supply is around 30kHz, which is determined bythe timing components R861, C863. Capacitor C863 is charged to 2.8V via the 5V reference voltage onpin 8 of I862 and discharge to 1.2V, during the discharge time interval, the oscillator generates a seriesof blanking pulses which cause the output at pin 6 of I862 to go low.The fly-back pulse from T440 is buffered by R864 and differentiated by C864, R863. A sharp pulse isthus obtained to force C863 to discharge, so that the oscillating frequency is synchronized and kept inphase with that of horizontal frequency to avoid interference on the display screen.Should the voltage vary due to the charge of input AC or output loading, the auxiliary winding willreflect these variation to pin 2 of I862 via D831, R831, R835. The voltage at pin 2 of I862 is comparedwith the internal 2.5V reference voltage to produce an error voltage is limited to 1V by internal zenerdiode and is compared with the voltage at pin 3 of I862 which is supplied from the voltage detectedacross R867, while Q868 is on. Q868 is off only when the voltage drop across R867 has reached that ofthe error voltage, or1 V p-p maximum.The error voltage controls the duty cycle of the pulse width modulator to regulate the output voltage.If over-load or short circuit occurs at the secondary, the voltage across R867 reaches 1 V p-p rapidly,thereby blocking the power output, the voltage at pin 7 of I862 then decrease to below 10V, I862 isforced off. However, in order to allow auto-recovery from power saving off state, the SMPS circuit isdesigned as an unlatched type, the DC current flows via R849 Q850, R850 to charge C866A again,when the voltage across C866A has reached 16V, I862 is turned on again. Once the peak voltage acrossR867 is over 1Vp-p, I862 will be forced off again.Consequently, the I862 is turned on and off repeatedly, and the power will not be switched off, Q868and R808 may be over stressed and fail.

6.2 Power Management CircuitThere are four modes of indicator in this power LED described as below, the first mode, “green-indicator “ indicates the normal state; “yellow-indicator“ indicates the stand-by and the suspend state.The fourth mode, “ amber-indicator “ indicates the power saving off state. Both H. sync and V. sync areoff

When the display signal enters the “suspend“ state of power saving, which is V. sync off, the voltage atpin 31 of I501 is low, Q821 is OFF, and Q820 is OFF too. this will shut down the oscillation of thehorizontal and vertical deflection, the power conservation is then achieved.When the display signal enters the “ off ” state of power saving which both H. sync and V. sync off, thevoltage at pin 31 & 29 of I501 are low, then Q820 is off and Q822 is off too, there is no 8V & 14VVoltage for the circuit.The overall power dissipation is significantly reduced to less than 5 watts.To recovery from off state to normal state is automatic since the recoved H. sync and V. sync willtrigger I501 via Q550 &Q556, The voltage on pin 29 & 31 will go to high again and turn on Q822,Q820 via Q823, Q821.Heater voltageThe heater element in the CRT is supplied with 6.3+0.3V during normal operation of the monitor and5.0+0.5V during suspend mode. To achieve the goal, Q851, D871 and associate circuit are introducedwhen atnormal state, a Horizontal pulse is fed to D871 via P807, Q851 is on, the feedback voltage on pin 2 ofI862 is normal, the output voltage of the secondary side of T801 is normal the heater voltage is 6.3V +0.3V.Horizontal output is shut down by making Q820 off during suspend state. There is no Horizontal pulsethen Q851 is OFF. The feedback voltage is higher than the normal state. this will force the outputvoltage of the secondary side of T801 drop down with the right value of R800, R832, R833, the heatervoltage is 5.0+0.5V.

6.3 Automatic and manual degaussing circuitWhen power switch getting started, MCU #38 will send out a "high" signal to turn on Q801.Simultaneously a current flows from B+14 via R807 and SR801 to make the relay on, the posistor R806and the degaussing coil L901 constitutes an automatic degaussing circuit to demagnetize the shadowmask and the internal shield of the CRT in order to protect the display screen from color impurity.The resistance value of the posistor is as low as 14 ohm during power off. Immediately after the displayturned on, a large AC current flows through the posistor into the degaussing coil for demagnetization.

12

At the same time, the resistor value of the posistor increases rapidly due to the rise of its temperature.The degaussing current thus decreases to less than 100mAp-p in a few seconds so that the displayscreen settles quickly, when the degaussing function is finished.Demagnetizing takes place even by selecting "Degauss" from the menu. MCU will be signaling a "high"level to Q801, hence the manual degaussing is activated.

6.4 Micro-Control CircuitThe monitor uses an advanced CPU (I501) to control the H. center; V. center, V. height, pincushion,trapezoid and so on by I2C BUS.The horizontal sync and vertical sync are buffered by Q550, Q556 and fed to pin 39, pin 40 of I501, theoutput sync signals are fed to pin 1, and pin 2 of deflection processor I401 via pin 33, pin 32 of I501.With the H. size control signal, the PWM control signal is derived from pin 2 of I501 which is fed into aintegration circuit R503, C503 and pull-up resistor R502 and buffer Q502 to give a DC control voltageon the emitter of Q502.The CPU is reset when the power cable is re-plug in. The components R506; D506 and C506 on pin 4of I501 ensure correct start.The +5V voltage is fed into I501 via pin 5, a 8 MHz resonator is connected on pin 7, pin 8 of I501 togenerate the CPU clock for the software execution. The user key control input is fed to an A/Dconverter on pin 14 via R515~R523, S516 and S517.The linearity control signal of horizontal circuit are derived from pin 15~pin 17 and pin 34 which arefed to the CS circuit Q402; Q404; Q480 and Q489There is a low power override pin on pin 30 of I501 this pin is pulled-up to 12V by R984, R986 ondrive board PWB-0045 and connected to pin 5 of the signal cable. When the signal cable isdisconnected from the computer, this pin is high and the Self-test pattern will work as described belowWhen you disconnect the signal cable from the PC, and power on the monitor, the display will producea moving square self-test pattern. The self-test function is useful to confirm the monitor is workingcorrectly.When the signal cable is connected to the unpowered computer, this pin is low and the power savingcircuit will be operated, the CPU will generate a power saving signal on pin 29 & pin 31 of I501The monitor is design to have the DDC 1/2b functions, communication between |the monitor andcomputer for DDC is via pins 24, 25 of I501 which are defined as SDA, SCL signals. The computer willread out the EDID data from the EEPROM I502 via IIC data lines. The EDID data is written into theEEPROM in the factory during production.The memory size for EDID data is 128 bytes shared from EEPROM 152 which has 4K bytes memorysize.

6.5 How to enter into the factory settingThe monitor includes 9 sets of factory preset timings although only some of the timings are fine-tunedby auto alignment during production.Switch off the monitor, push and hold down the "select" key and power on again, wait 1.0 second thenrelease the "select" key, the monitor should now be in the factory setting mode. (OSD in bluebackground), All adjustment data will be stored automatically, then power on again, the monitor willrevert to normal operating state.

6.8 Vertical Deflection CircuitThe power amplifier driving the vertical yoke assembly is a DC design-based on power amplifier I330TDA8172.The vertical deflection coil is connected to pin 5 of I330 via P440. The sawtooth signal is derived frompin 23 of I401 and fed to pin 1 of I330 via R330 / C330. The DC bias voltage is derived from pin 21 ofI401 and fed to pin 7 of I330 via derived R347 / R348 to optimize the vertical position. R335 /C336 isto stabilize the power amplifier output.There are two supply voltage for I330, -9V is applied at pin 4 via R334, +14V DC voltage is applied atpin 2 and pin 6 via D344 for the output stage during the retrace time. The supply voltage for the outputstage during the retrace time is derived from the fly-back generator output on pin 3 of I330 and appliedthrough C343 to pin 6 of I330.

6.9 Horizontal Deflection CircuitThe product is designed around a base-drive circuit driving horizontal deflection circuit to providesufficient switching current.Q429 is switched by the horizontal drive signal from pin 26 of I401 via level-shift component R424, C427, and D428. This produces a sufficient voltage to T430, snubber networkR429, C429 compensates for leakage inductance in T430 and shapes the base drive waveform.The drive signal is fed to Q433 via D431, R431. When Q433 is at the “ off “ state, the voltage, which isstored on the base of Q433, discharge via R431, D431. The drive signal controls Q433 switch on andoff, so that saw-tooth waveform current through the horizontal deflection coil is obtained.The positive horizontal fly-back pulse signal derived from pin 6 of T440 is divided by R405A / R326 /R524 then fed to pin 12 of I401, this fly-back signal not only provides proper timing reference forhorizontal drive output but also supplys necessary blanking for video output.The horizontal deflection output circuit uses the transistor switching function. Combined with a damping diode and makes saw-tooth wave current flows through a deflection coil. The basic deflection circuitcomprises switching transistor Q433; transformer T440; damper diode D435; Co, C434/C435;CsC405/C472/C477 and linear coil L483/L454.

6.10 Horizontal Width ControlThe monitor uses a diode modulation circuit. For the control of width, it is achieved by changing thebase voltage of Q467. The control voltage (0V ~5V) is derived from pin 2 of CPU I501 via Q502, anychange of DC voltage on the base of Q470 will vary the DC resistance between the collector and emitterof Q470. Low DC resistance on Q470 will cause large width control current flows into Q470 via L471and then the horizontal width is increased.

6.11 Pincushion ControlThe two pincushion control signals are derived from pin 24 of I401 and the one pincushion controlsignals AC coupled to the base of Q467 via C464 and divider R463/R464 the other pincushion controlsignal will amplifier by Q466 and 12 DC couple via C464 to the collector of Q467. Those parabolasignals. modulates the horizontal width automatically so that dynamic pincushion correction ( DPC) isachieved.

6.12 Video CircuitThere are three the ICs applied for the video circuit. I901 is a three channel pre-amplifier IC; I903 isOSD display IC I904 is for video output amplifier IC The analog R G B video input signal are suppliedthrough the cable, which is terminated at P901, these input signal are approximately 0.7 Vp-p inamplitude. R901/R931/R961 give a resistance of 75 ohm for impedance match. The R G B video signalare AC coupled via C901/C931/C961 then fed into the video pre-amplifier I901 at pin 11, pin 6 and pin2 respectively.After being pre-amplified, the R. G. B. video signals are output from pin 35, pin 32, and pin 29 of I901respectively. The amplitude of the signal at theses output are about 3 ~ 4 V p-p. Those video signals areconnected the I904 at pin 11, 9, 8 respectively.The I904 is video output amplifier to amplify the mixed R, G, and B signal. They offer about 40 V p-psignal in amplitude to drive the cathodes of CRT. L912, L942, L972, are the peaking coils, for thecompensation of high frequency response.The contrast adjustment is controlled by SCL and SDA which fed into the pin 20, 21 of the I901,through the internal D/A converter then controls the subcontrast and the main contrast, so that we canhave different variation output in amplitude on pin 29 (R), pin 32 (G), pin 35 (B).The beam current limit circuit, which is composed of D941 and its peripheral components,automatically responds to the dynamic or static variation of beam, current of the CRT. The ABL voltageis fed into pin 15 of the I901. If this voltage lower enough will actuate the limitation to the internal maincontrast, preventing the picture too much bright.The DC brightness bias voltage derived from R902, R903 is applied to pin 30 of I901 holding theconstant DC bias of the video amplifier during the reference portion of the black level of the videowaveform. The cathode cut-off setting voltage required for white balance is obtained from respectivepin 23 (r), pin 25 (g), pin 26 (b), outcomes, these output magnitude can control the degree of conductingof trimsistor Q903, Q933, Q963 individually so that the DC bias of the cathode are then variedoptimizing the colour temperature of back ground.

6.13 Brightness Control CircuitThe -155V is obtained from the FBT # PIN 7 negative fly-back pulse via rectifier D489, through R484,R482, R357 to supply necessitating G1, voltage to the CRT. This G1 voltage is circa-75V.The brightness control of the monitor is achieved by changing the G1 voltage via Q495, Q497. The

16

control voltage is derived from the pin 26 of I501, the variation of the DC voltage on the base of Q495via R492 will vary the G1 voltage via R498, Resistor R482 is used as sub-brightness to set the G1voltage.

6.14 Spot Killer CircuitThe spot killer circuit is included, in order to prevent damage of the CRT whilst switching power off.During the power on due to the voltage drop on R351, D348 from -155V, makes the voltages on the #B,#E of the Q348 is reversed, so Q348 remains non-conducting, whereas when powered off, the negativepolarity of the C349 will drop drastically to around 225V, this change will leading to the Q348conducting, therefore draw the G1 voltage to this deep minus voltage to cut off the beam current.

6.15 Blanking CircuitThe vertical blanking pulse is produced from pin 5 of I330 via R337, C337, R339, R340, and D338. It isalso combined with horizontal blanking signal via network R342, C342. Both of the signals are fed tothe amplifier Q341, Q353. This blanking signal is fed to G1 via C355.

6.16 Horizontal Position (Raster) CircuitThe adjustable horizontal raster centering is achieved by using the circuit of D485, D486, R485 byadjusting P402 in either a DC-CS AC current element the positive or negative magnitude of this ACcurrent compare with the centeral zero level can deeide the picture scanning inclines to left or right side,via flow in or flow out of the L485 into the yoke assembly. The background raster should be centralizedwith respect to the edge of the bezel by proper insertion the P402.

6.17 HV. B+ Control CircuitThis circuit generates the supply voltage for the horizontal scanning circuit. This supply voltage isapproximately proportion to the H frequency in order to keep the scanning amplitude constant when thehorizontal frequency changes. The circuit is a step-up converter and it uses the current mode regulationprinciple.The feedback signal is derived from pin 9 of T440 via, R443 and R325A Peak-detected by C451, R451,is fed to the error amplifier on pin 15 of I401. The value of R325 is chosen to get a suitable gain for theerror amplifier. A saw-tooth waveform related to the output current of Q440 as a I-sense is fed to pin 16of I401 via R442, R440 and C326.Both of the feedback and saw-tooth I-sense waveform are fed to a comparator in I401 to generate aPWM (Pulse Width Modulation) control signal output pin 28 of I401.A square waveform control output on pin 28 of I401 is then fed to Q440 via buffer Q438, Q439. Q440 isdesigned as a step-up voltage converter and the DC voltage is fed to the Drain of Q440 via L440. Theenergy is stored in L440 when Q440 is on; the energy is released when Q440 is off.The circuit supplies DC voltage (60V ~ 190V) to pin 9 of T440 via Q440 and D442. The snub circuitC442, R444, R441and C441 is for the noise transaction.

6.18 Fail-Safe ProtectionThe fail-safe shut down protection is activated when anode voltage exceeds certain radiation safetylimit. The fail-safe control voltage is derived from pin 9 of T440 via R452/ R447 and D446 and pin 6 ofT440 then applied to the pin 25 of I401, the input at pin 25 of I401 is a DC voltage with typical shutdown voltage of about 8V. It will block the H-drive output and H&V blanking output when the fail-safe

17

is activated. The protection is reset and return to normal operation either by power off and on or by I2C.

6.19 RotationThe control signal on pin 3 of I501 is to adjust the display tilt when you press "-" key. The voltage onbase of Q203 rises and causes current Ic of Q202 increased. By virtue of current flow, rotation coilmakes the display a bit tilt. The display will tilt anti-clockwise when pressing "+".
