Refer to the block diagram on page 15 (foldout) when reading this description. A The Video Interface is designed around a custom IC and will accept DC or AC coupled positive analog video signals. It can also be used with negative analog and 4 line TTL. This IC has a built in multiplier circuit for the master gain control and blanking functions. Resistors are used to protect the IC and to set the gain. The programmed gain is dependent on the input signal amplitude except with the TTL mode.
E The CRT Auto Bias IC is a combination of digital and analog circuitry. The digital part is a counter and control logic which steps the analog circuits through a sequence of sample and hold conditions. The analog part uses a transconductance amplifier to control the voltage on a 10uF capacitor (one per gun). This voltage is buffered and sent to the video amplifiers as the bias voltage. In monitors without CRT auto bias, this voltage is adjusted manually using a setup procedure to set the color balance.
H The CRT for the 1493, 1793 and 2093 monitors have a 90° deflection angle. The 1993 incorporates 100° while the 2793 CRT has 110° and the 3693 has 111° deflection angles. These picture tubes have integral implosion protection and a EHT of 25KV. H1 The Vertical Dynamic Focus amplifies the parabolic waveform across the vertical coupling capacitor from about 3Vp-p to about 200Vp-p, depending on CRT requirements. This waveform sharpens the top and bottom portion of the raster on dual focus CRT's.
The sync pulse from the LA7851 triggers a one shot in the LA7838 which clamps the vertical ramp generation capacitor to 5V during the first half of vertical retrace. The ramp generation capacitor then charges via a constant current set by an external resistor. This resistor is connected to the V SIZE pot, located on the remote control board, for the vertical size adjustment. The vertical drive is a differential amplifier which compares the ramp voltage to the yoke return feedback current.
Q The Remote Control PCB houses the: CONTROL 1. 2. 3. 4. 5.

XX93 Monitor Block Diagram. U The Switching Regulator is synchronized to the horizontal pulse and drives a power MOSFET. Unlike most regulators that have a common GND, this power supply has a common V+ and current is supplied from V- to GND. The MOSFET is connected to V– and signal ground (GND) through a transformer which is used as an inductor for series switch mode regulation.

CRT AUTO BIAS AND AUTO BRIGHT CIRCUIT, FUNCTION, DESCRIPTION. The auto bias circuit is a control system that forms a closed loop for controlling the CRT bias voltage. It generates a set of conditions where the current near the cutoff voltage of each gun is measured, and then adjusts the bias voltage of the video amplifiers, to set the correct black level voltage for each gun.
CRT AUTO BIAS AND AUTO BRIGHT CIRCUIT DESCRIPTION. The beam current feedback circuit uses a PNP video transistor 954 954 to direct most of the beam current to the auto bias circuit while passing the voltage waveform, from the video amplifiers to the CRT cathodes. Diode 956 insure that no video waveform 958 and capacitor 956 distortion occurs. An additional benefit of this circuit is that it protects the video amplifiers from the destructive 955 divide energy due arc energy.

POWER SUPPLY, TROUBLE SHOOTING TIPS. SAFETY FIRST; Use only one hand when working on a powered up monitor to avoid electrical shock. Always wear safety glasses. Many of the failures that cause burnt components and boards are eliminated by the load sensitive switching mode power supply in the CERONIX monitor. This feature can cause problems with servicing the monitor if the proper trouble shooting approach is not used.
Trouble Shooting Handbook The information that is written in this handbook is to help repair XX93 Monitors. Here is a guideline in which this handbook will follow: 1. 2. Color problems. No video with power. 3. No V-H sync. 4. 5. Retrace lines. No power. Always wear safety glasses. Caution; Use only one hand when working on a powered up monitor to avoid electrical shock. Color Problems.
Problem Excessive color. Turn down G2 (bottom pot of FBT) if excessive color is too bright. Refer to the schematic for the specific pin numbers of each color. Tests should preformed in order to reduce chance of replacing wrong component. Problem Tests Probable Solution 1. Turn down M. Gain. Measure voltage of K-Film pin 1 for each color. If affected color has a .3V difference then others Desolder pin 1. Make open to trace. If pin 1 still different replace K-Film. 846 . 2. Measure voltage across cap.

Filament Voltage Test. When replacing either the flyback transformer or the video board, the filament voltage may not be correct. Measuring the filament voltage is not accurate using a true RMS voltage meter, because of the high frequency components, which make up the filament voltage. An oscilloscope, with RMS capability, may be used to measure the filament voltage.
HeizfadenSpannung Test. Wenn der EHT-Transformator oder die Videokarte geändert wird, kann die Heizfadenspannung falsch sein. Die Heizfadenspannung besteht aus Hochfrequenzbestandteilen. Genaues Messen der Heizfadenspannung kann nicht mit einem Effektivwertmeßinstrument erhalten werden. Ein Oszillograph mit Effektivwertmessen-Fähigkeit kann benutzt werden, um die Heizfadenspannung zu messen.
SETUP AND CONVERGENCE PROCEDURE 1. Use a knife to brake free the magnetic rings on the yoke, which are usually locked with red varnish. Bring the adjustment tabs on each pair of magnetic rings in line for the starting point. 2. Loosen the yoke clamp. Remove the yoke wedges and the tape from the CRT. 7. Adjust the yoke position, on the CRT neck, to the center of purity.

Circuit Function Description. The basic function of the ISO XFR-75W and ISO XFR-100W is to isolate the line power for monitors requiring an isolation transformer. The transformer is designed to have a low leakage flux value which allows it to be mounted close to the CRT. To accomplish the low leakage flux, the transformer has two sets of primary and secondary coils mounted on a modified toroid type core.
