To understand how the Monitor works, it is best to know what each circuit
does and how each circuit relates to the other circuits. The Block Diagram is
presented in a simplified view and a comprehensive view to accomplish the goal of
understanding the whole unit. Once the general picture is clear, the complexity of
each circuit will be easier to understand.

The Circuit Description is also written in two views, a simplified view and a
detailed view to help give the reader a clear understanding of what each
component does. This understanding is most helpful for the more complex
problems or multiple problems that sometimes occur.

The power supply trouble shooting section describes methods used to power up
various monitor circuits, when there is a fault in the monitor, which disables the
power supply.

The appendix includes; filament voltage test, convergence procedure,
replacement parts purchase order form, degaussing coil attachment specification,
high pot test, wire routing drawing, production assembly drawings (PADs), C, I, J,
& K film resistor arrays and a parts list addendum. The parts list addendum is
used to add new information describing part changes. Tables, suitable for pasting
on these pages, will be published as new variations of the XX93 monitors are
produced.

This block diagram gives a broad view of the circuit organization of the 1493,
1793, 1993, 2093, 2793, and 3693 monitors. The blocks with the bold outline
represent circuits which provide these monitors with a wide range of
operating conditions without the need for adjustment.

The video interface circuit can be programmed to accept; +Analog AC or
DC coupled, -Analog, and 4 line TTL. The M. GAIN or contrast control is
located on the remote control board.

The auto bias circuit eliminates the need for the color setup procedure.
This circuit is designed to actively compensate for picture tube drift which
normally causes unbalanced color. The auto bias circuit also adjusts the
CRT gain to compensate for gain loss with age.

The horizontal size control circuit permits the horizontal size to be adjusted
from a remote control board. This circuit is also used to compensate for
pincushion distortion and blooming. Anti-blooming is accomplished by
correcting horizontal size variations which are caused by the additional load
on the flyback transformer under high beam current conditions.

Careful reading of all the information presented in this manual is a good
way to learn how to repair the CERONIX monitor.

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. Solder jumpers and component substations are used
to program the Video Interface for the type of input signal to be received. The
output of the IC drives the video amplifiers. This drive is a current where 0 mA
is black and 10 mA is a saturated color.

B

The Video Amplifiers are of the push pull type. They are built partly on thick
films and partly on the video PCB. Spreading out the amplifier reduces the
component heat and improves the life of the unit. The bandwidth is 25 MHz with
40Vp-p output. The rise and fall times are 20nS.

C

The Beam Current Feedback circuit directs most of the beam current of each
amplifier to the beam current buffer. The only time this current is measured, by
the auto bias circuit, is during the time of the three faint lines at the top of the
screen and three lines thereafter. The CRT auto bias circuit is designed to adjust
the video amplifier bias voltage such that the beam current of each of the three
guns is set to a specific programmed value.

D

The
current signal into a low impedance voltage. This voltage is applied to the auto
bias IC through a 200 ohm resistor. After the three lines of beam current are
measured, the program pulse from the auto bias IC, produces a voltage drop
across this 200 ohm resistor that equals the amplitude of the beam current
voltage.

9

Beam Current Buffer converts the, high impedance low current, beam

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. With CRT auto bias, the color balance is set during the end of
each vertical blanking time.

The control sequence is:

1.

The cycle starts with a sync pulse from the vertical oscillator (15KHz)
or from the vertical sync delay. 15H later the grid pulse starts.

2.

The grid pulse on G1 causes cathode current which can be seen as the
three faint white lines at the top of the screen. This cathode current is
transmitted by the beam current feedback to the beam current buffer
where it is converted to a voltage and applied to the CRT auto bias
input pin. At this time the CRT auto bias IC outputs a reference
voltage at its input pin which sets the voltage across the coupling
capacitor. This coupling capacitor voltage is directly dependent on
beam current.

After the grid pulse is over, the program pulse matches the voltage

3.
from the beam current buffer. If the voltage from the beam current
buffer, during the grid pulse, is the same as the voltage from the
program pulse, the bias is correct and no bias adjustment is made for
that vertical cycle.

F

The timing of the auto bias IC is synchronized to the vertical oscillator and the
flyback pulses. For horizontal frequencies higher than 15.7KHz a Vertical Sync
Delay may be needed to position the grid pulse, generated 3 gray lines, at the top
of the screen. The need for the delay circuit is dependent on the particular CRT
vertical retrace time.

G

The aging of the picture tube (CRT) not only affects the balance of the cathode
cutoff voltage, which is corrected by the auto bias circuit, but it also affects the
gain of the CRT. The
by sensing any common bias voltage change, from the auto bias circuit, and
adjusts the screen voltage to hold the average bias voltage constant. The lower
adjustment on the flyback transformer which is the screen voltage, is used to set
the auto bright voltage to the center of its range. Therefore, the auto bright
circuits sets up a second control feedback loop to reduce picture variation due to
CRT aging. The auto bright circuit is also used to turn off the beam current when
the monitor power is turned off.

Auto Bright circuit actively corrects for CRT gain changes

10

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.

H2

The
horizontal coupling capacitor, using a transformer to produce 300Vp-p output from
an input that is about 33Vp-p. This waveform is added to the vertical dynamic
waveform and sharpens the right and left sides of the raster.

Blanking is accomplished by setting the gain of the interface IC to zero during
blank time. The Horizontal Blanking pulse is generated by amplifying the flyback
pulse. The Vertical Blanking pulse is started by the vertical oscillator one shot
and ended by the counter in the auto bias IC via the "bias out" pulse. The Master
Gain control, located on the remote PCB, sets the gain of the video signal when
blanking is not active. The Beam Current Limiter circuit, which is designed to
keep the FBT from overloading, will reduce the video gain if the maximum
average beam current is exceeded. Also, the beam current is reduced if the FBT
approaches maximum operating temperature.

The
used to receive sync, one for vertical sync and the other for horizontal sync.
Resistor dividers are used to protect the comparator IC from over voltage damage.
For customers who do not require interlace, an additional vertical sync
stabilization circuit is included. This circuit synchronizes the vertical sync to the
horizontal cycle.

K

Vertical Oscillator generates the vertical free running frequency when no

The
vertical sync is present. When sync is applied, the vertical oscillator synchronizes
to the leading edge of the sync pulse.

L

The Vertical Control & Output circuit consists of:

1. One shot.

2. Ramp generator.

3. Vertical drive.

4. Vertical output.

11

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. The yoke feedback current and voltage circuits are used to set
the vertical linearity. The vertical Output is a power driver, with thermal
protection, which drives the vertical deflection yoke. It also has a special pump up
circuit which doubles the output voltage during vertical retrace. This voltage
doubler also increases the efficiency of the circuit since the high retrace voltage is
not present across the power driver during the trace time.

M
The
loop to generate the horizontal timing. The H POS. adjustment, on the remote
control board, sets the sync delay time which controls the picture position. The
phase locked loop uses the flyback pulse to generate a sawtooth wave which is
gated with the delayed sync pulse to control the horizontal oscillator.

Horizontal Control incorporates a variable sync delay and a phase locked

N
The Horizontal Driver supplies the high base current necessary to drive the

horizontal output transistor which has a beta as low as three. A transformer is
used to step up the current from the driver circuit and also protects the horizontal
output transistor from a continuous turned on state. A special clamp circuit is
connected to the transformer which reduces the turnoff time of the horizontal
output transistor for reduced power dissipation.

O

The Horizontal Output transistor is mounted to the rear frame which acts as a
heat sink. The collector conducts the 900 volt primary flyback pulses which should
not be measured unless the equipment is specifically designed to withstand this
type of stress. A linear ramp current is produced in the horizontal yoke by the
conduction of the horizontal output transistor (trace time). A fast current reversal
(retrace time) is achieved by the high voltage pulse that follows the turn off of the
horizontal output transistor. This pulse is due to the inductive action of the yoke
and flyback transformer.

P

The main function of the Flyback Transformer (FBT) is to generate a 25,000 volt
(EHT) potential for the anode of the picture tube. This voltage times the beam
current is the power that lights up the phosphor on the face of the picture tube.
At 1.5mA beam current, for the 2793 monitor, the FBT is producing almost 38
watts of high voltage power. The FBT also sources the focus voltage, screen grid
voltage, filament power, and has two more secondaries which are used for control
functions. The FBT has a built in high voltage load resistor which stabilizes the
EHT, for the low beam current condition. This resistor also discharges the EHT,
when the monitor is turned off, which improves the safety of handling the
monitor.

3. V RAS. POS. --- Vertical raster position ------- DC current to V. yoke

4. H POS ------------ Horizontal picture position -- H. sync delay

5. M GAIN ---------- Master gain ---------------------- Video interface

R

The Horizontal Size Control circuit has four inputs:

# SIGNAL FUNCTION

2. Beam current -------------------------------- Blooming control

3. Vertical linear ramp -----------------------

4. Vertical parabolic + V. linear ramp ---

(#4)-(#3)=Vertical parabolic

}

(Pincushion)

The horizontal size control circuit sums the four signals at one node plus the
feedback from the diode modulator to drive a switching mode power driver. The
output of the power driver is then connected to the diode modulator through an
inductor to complete the control loop.

S

The Diode Modulator is a series element of the horizontal tuned circuit. It forms
a node between GND and the normal yoke return circuit. If this node is shorted to
GND, the result is maximum horizontal size. Forward current in the diode
modulator, at the start of retrace, keeps the node voltage clamped to ground until
enough current flows from the horizontal tuned circuit to exceed this forward
current. The horizontal size, therefore, is controlled by controlling the current to
this diode via the horizontal size control circuit.

T

A Voltage Doubler is used in the power supply for two reasons:

13

1. To improve the efficiency of the power supply.

2. To permit 120 volt and 230 volt operation. For the 230 volt
operation the voltage doubler is replaced with a bridge rectifier.

U

XX93 Monitor Block Diagram.

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. An operational amplifier, voltage reference, comparator, and oscillator in the power
supply controller IC are used to accomplished regulation by means of pulse width modulation.

The transformer has two taps on the main winding which are used to generate the +16 volt
and +24 volt supplies. It also has a secondary which is referenced to V- and supplies the power
supply. Since the power supply is generating its own power, a special start up circuit is built
into the power supply controller IC that delays start up until the capacitor which supplies the
IC is charged up enough to furnish the current to start the power supply. This capacitor is
charged with current through a high value resistor from the raw dc supply. This self sustaining
action is why the power supply chirps when an overload or underload occurs. Additional
secondaries to drive the horizontal raster shift circuit and the video amplifiers are also included
in the power transformer.

V

The Load consists primarily of the horizontal flyback circuit. The power supply will not
operate without the load since the voltage that sustains the power supply comes from a
secondary in the power transformer and depends on some primary current to generate
secondary current.

W

A +12V regulator is used to supply current, to all the control circuits in the monitor, with the
exception of the power supply. Many of the control circuits are decoupled from the +12 volt line
with a resistor or diode to minimize noise from common current loops.

X

The Over Voltage Protect circuit is built into the power supply and monitors the flyback
transformer peak pulse voltage. This circuit will turn off the power supply and hold it off if the
EHT exceeds its maximum rated value. Since excessive X-ray output occurs with excessive
EHT, this circuit provides X-ray protection.

Y

The Fault Detector senses beam current and temperature. This circuit will activate the
power supply shutdown circuit if either the maximum temperature is sensed or if the beam
current becomes large enough to threaten the FBT.

Z

The Degaussing circuit is connected across the isolated AC line. A posistor is used to allow a
large current to flow, in the degaussing coil, on power up. This current is then gradually
reduced by the increased temperature of the positive temperature coefficient thermistor in the
posistor. A relay is used to short the degaussing coil after the degaussing operation. This
greatly reduces posistor residual current in the degaussing coil. When repairing a monitor, the
degaussing coil should be unplugged, to avoid possible damage to the degaussing coil shorting
relay.

Safety Critical Components for XX93 Monitors.

PRODUCT SAFETY NOTE:

Components marked by the symbol ! have special characteristics important to safety.
When replacing any of these components, be sure to use the parts specified in the parts
list.
An example of how the critical components are marked in the Master Part List is shown
below. See the Master Part List for specifying critical components.

102 CPC1027 D2 HH8 6,800pF ±5%, 100V, Film!

CAUTION:

CERONIX XX93 Monitors MUST USE AN APPROVED ISOLATION
TRANSFORMER.
The monitor chassis must be connected to earth ground via a common connection
in the system which contains the monitor.

X-RAY NOTE:

X-radiation is produced by electrons colliding with the phosphor and shadow mask at the
front of the picture tube. The X-radiation emanating from the front of the picture tube is
highly reduced due to the shielding affect of the leaded glass face.
It is also produced at the anode bulb contact. The X-radiation emanating from the anode bulb
contact is much higher than from the face due to less shielding.
X-radiation is directly proportional to beam current. It doubles for each 1.3KV increase of
the EHT voltage at the face and also doubles for each 3KV increase of the EHT at the anode
bulb contact.

From this information, it should be noted that when servicing monitor electronics, where the
back of the picture tube is facing the service person, that the beam current should be turned
down to avoid excessive exposure.
Due to the increase in X-Radiation emission with increase of EHT voltage, it is important that
the EHT voltage is checked.
To measure the EHT voltage: Connect the (-) lead of a volt meter to the monitor chassis so
that a reliable connection is made. Connect a high voltage probe to the (+) input of the meter
and at the anode contact of the picture tube.
The EHT should not exceed 26KV at 0 beam current.

VORSICHT:

MONITOREN CERONIX XX93 MÜSSEN EINEN ANERKANNTEN
LOKALISIERUNG TRANSFORMATOR BENUTZEN.
Das Monitorchassis muß an die Masse angeschlossen werden, die über einen
allgemeinen Anschluß im System gerieben wird, das den Monitor enthält.

RöNTGENSTRAHLANMERKUNG:

X-Strahlung wird durch die Elektronen produziert, die mit der Phosphor- und
Schattenschablone an der Frontseite des Abbildung Gefäßes zusammenstoßen. Die
X-Strahlung, die von der Frontseite des Abbildung Gefäßes ausströmt, liegt in hohem Grade
an der Abschirmung beeinflussen vom verbleiten Glasgesicht verringertes. Sie wird auch am
Anode Birne Kontakt produziert. Die X-Strahlung, die vom Anode Birne Kontakt ausströmt,
ist viel höher als vom Gesicht, das zu weniger abschirmen passend ist. X-Strahlung ist direkt
zum Lichtstrahlstrom proportional. Sie verdoppelt für jede Zunahme 1.3KV der
EHT-Spannung am Gesicht und verdoppelt auch für jede Zunahme 3KV des EHT am Anode
Birne Kontakt.

Von diesen Informationen sollte es beachtet werden daß, wenn man Monitorelektronik
instandhält, in der die Rückseite des Abbildung Gefäßes die Service-Person gegenüberstellt, daß
der Lichtstrahlstrom unten gedreht werden sollte, um übermäßige Berührung zu vermeiden.
Wegen der Zunahme der X-Radiationemission mit Zunahme der EHT-Spannung, ist es wichtig,
daß die EHT-Spannung überprüft wird.
Die EHT-Spannung messen: Schließen Sie die (-) Leitung eines Voltmeßinstruments an das
Monitorchassis an, damit eine zuverlässige Beziehung hergestellt wird. Schließen Sie eine
Hochspannungsprüfspitze an den (+) Input des Meßinstruments und am Anode Kontakt des
Abbildung Gefäßes an.
Das EHT sollte nicht 26KV bei 0 Lichtstrahlstrom übersteigen.
