CAUTION WARNING

TUBE REPLACEMENT. The monitor tube incorporates x-radiation and implosion protection. To assure continued safety, replace the tube with the same type or a recommended replacement.

!

CAUTION WARNING

Handle Fluorescent Tubes and CRTs with Care. Most GDs contain fluorescent lamp tubes. A video machine includes a monitor with a fragile CRT. Fluorescent tubes and CRTs are evacuated glass containers. The vacuum exerts considerable stress on the glass. Because of this stress, if you drop a fluorescent tube or CRT, it may implode! Shattered glass can fly eight feet or more from the implosion. Take care when handling a monitor. Determine where you'll place the monitor before you remove it.

NOTICE To improve the product, EMC revised the main circuit board. The revision involves a new sync processor at IC801. The older, model EMC-3000 circuit board uses part 503100-3000 at IC801. The newer, model EMC3000A circuit board uses part 503-100-3001 at IC801. This book’s replacement parts list only itemizes the original main circuit board. See the Two Model Parts Comparison List for components that differ between the old and new circuits. Please check the chip type at IC801 before making repairs.

Circuit Description Power Circuit The power circuit includes the line filter, input rectifier circuit, startup, current-mode control and over-voltage protector (OVP). Please refer to the circuit diagram.

Line Filter Circuit The line filter is comprised of C502, C503, C504, L501 and L502. This line filter tends to reduce the noise of conducted EMI from the monitor into the power line.

Input Rectifier Circuit The input rectifier circuit is comprised of BD501 and C506. BD501 and C506 is a half-wave rectifier. R501 is reduces the surge current while the power supply is turned on.

Startup Circuit Resistor R503 provides startup current for IC501. The turn-on and turn-off thresholds of the under-voltage lockout circuit in IC501 are set interna!ly at 16V and 10V respectively. To start up, C513 must be charged to 16V with a current of 0.5mA to 1mA. These voltages and currents depend on the IC501 startup current characteristics and R503 resistor value.

Current-Mode Control Operation When the Vcc of IC501, pin 7 charges to more than 16V, a square wave appears at output pin 6. This square wave can be adjusted to peak +1 amp for driving the Q501 gate. Current-sensing resistor R517 senses the primary current wave to control the current-mode PWM and limit total output power. Pin 2 and Pin 1 connect to an error amp section. IC501 detects the output voltage at pin 2 and controls the output pulse width of pin 6. IC501 also regulates the output voltage during changes in the line voltage and load current.

OVP Circuit R514, ZD502, and R515 are OVP components. When the input voltage exceeds the detected point value, Q502 turns on, shutting down IC501.

Synchronous Processing Circuit The IC801 circuit is a synchronous signal processor of multi-sync. IC801 is capable of many functions such as horizontal and vertical frequency discrimination, display mode selection and synchronous pulse polarity detection. Pin 1 and Pin 2 function as a clock generator. Output pins 5 and pin 6 are active low, fixed polarity. Output pulses at these pins maintain the same width as the original horizontal and vertical sync signals. Active low pins 7 to 9 function as a frequency discriminator. Pins 11 to 19 function as an output mode selector. These pins control the vertical size, horizontal phase and horizontal oscillator for every display mode. 8

Vertical Deflection Circuit IC301 is a full-performance and very efficient vertical deflection circuit. IC301 drives the deflection yoke directly. Besides many other special features for the vertical circuit, IC301 contains the synchronization circuit, oscillator, and power output amplifier. The output amplifier can handle high currents. The vertical sync enters pin 5 of IC301. Components R305, R335, C304, D305 and ZD301 determine the oscillation frequency. The deflection yoke connects to pin 1. The sawtooth pulse generator inside the IC can generate a sawtooth signal through a buffer stage to pin 9. Then, the signal enters the linearity control circuit via R307, R308, C305 and C306. VR301 adjusts the vertical linearity. VR302 adjusts the vertical size. IC801 regulates the picture’s vertical size under different scanning modes. This circuit also includes resistors R804, R805, R806, R807, R808 and R809. The circuit maintains vertical size within ± 5 mm of these specs... • 48 cm Monitors: 270 mm • 41 cm Monitors: 220 mm • 34 cm Monitors: 180mm

Horizontal Processing Circuit IC601 is a horizontal deflection processor. It contains the oscillator, AFC, xray protector, phase shifter and pulse duty setting. The horizontal sync signal exits the sync processing circuit, and enters IC601 at pin 1. VR602 is an external, horizontal phase control. Q607 and Q608 are internal, horizontal phase auto adjustment controls. VR601 is an internal, horizontal oscillation control. VR603 is the x-ray protector. The flyback pulse occurs at T603, pin 6. D601 and C612 rectify the flyback pulse, producing 26VDC at TP1. Under normal conditions, ZD601 measures open. You can adjust VR603 to obtain 5.4VDC at TP2. Under abnormal conditions, the TP1 voltage increases, creating a current through bleeder resistors R625, VR603 and R626. This current turns on ZD601. Next, the current flows to IC601, pin 13 to activate the x-ray protector circuit. The x-ray protector disables IC601, pin 12. Normally, the horizontal drive appears at this pin.

Horizontal Deflection Circuit The horizontal deflection circuit includes the horizontal driver and horizontal output circuit. The horizontal drive pulse at pin 12 of IC601 feeds into Q605 to drive transformer T601. This pulse then drives the output transistor Q606 to generate horizontal deflection current. Q606 also drives the flyback transformer (FBT), producing high voltage. Coil L602 adjusts raster width. L603 is a linearity coil, which enables “S“ wave correction. VR305 is the pincushion correction gain control. It compensates for the horizontal distortion of side scanning.

Video Circuit The video circuit includes two major parts. One is the analog video processing circuit and the other is the video amplifier circuit. Analog video processor IC201 includes a gain control and DC restoration circuit. RGB video signals enter IC201 inputs through coupling capacitors C201, C202 and C203. Video gain control VR201 normally limits the RGB Kristel Video Monitors

output voltage at IC201 to between 3.5 and 4.0 VDC. This voltage changes according to the 0.7Vpp input level. The input level depends upon the DC voltage from the contrast potentiometer. This DC voltage appears at IC201, pin 12. A cascode circuit amplifies each RGB signal, in order to eliminate the Miller Effect at the high resolution display. Resistors R230/R216, R233/R221 and R236/R227 calculate the values of each channel’s gain. Coils L203, L204 and L205 are series peaking inductors. Components R217, C221, R222, C222, R228 and C223 form emitter peaking circuits. The output amplifier circuit stage consists of transistors Q206, Q207, Q209, Q210, Q212 and Q213. This stage amplifies the video signal to 40Vpp. Spark gaps SG201, SG202, SG203, SG204, SG205 and resistors R252, and R253 are arc protection components. They protect electrical components during a CRT arc condition. Variable resistors VR204, VR205 and VR206 are CRT cathode bias controls. They establish the CRT’s white balance.

Horizontal Size and Side Pincushion Circuit (For full screen models) A full-screen monitor’s raster occupies the CRT’s entire face, and lights all phosphors. Also in these monitors, the picture completely covers the raster. Full-screen models achieve picture width control and side pincushion compensation by changing the horizontal deflection circuit’s source voltage. The diode modulator circuit includes these components: C624, L602, C618, D603, D613, D614, C619 and horizontal yoke P604. A parabolic wave enters the Q310 base via a double integrated circuit. This IC generates the side pincushion compensation wave. Transistors Q310 and Q311 amplify the horizontal width control voltage and parabolic wave. The diode modulator uses these signals to control the source voltage of the horizontal deflection circuit.

Two-Model Parts Comparision List To improve the product, EMC revised the main circuit board. The revision involves a new sync processor at IC801. The older, model EMC-3000 circuit board uses part 503-100-3000 at IC801. The newer, model EMC-3000A circuit board uses part 503-100-3001 at IC801. This book’s replacement parts list only itemizes the original main circuit board. See the Two Model Parts Comparison List below for components that differ between the old and new circuits. Please check the chip type at IC801 before making repairs.
