2. PRECAUTIONS AND NOTICES

2-1

SAFETY PRECAUTIONS

Observe all caution and safety related notes located inside the display cabinet.

Operation of the display with the cover removed, may cause a serious shock hazard from the display power supply. Work on the

display should not be attempted by anyone who is not thoroughly familiar with precautions necessary when working on high voltage

equipment.

Do not install, remove or handle the picture tube in any manner unless shatter-proof goggles are worn. People who are not so

equipped should be kept away while handling picture tube. Keep picture tube away from the body while handling.

The picture tube is constructed to limit X-RAY radiation to 0.5 mR/HR. For continued protection, use the designated replacement

tube only, and adjust the voltages so that the designated maximum rating at the anode will not be exceeded.

Before returning a serviced display to the customer, a thorough safety test must be performed to verify that the display is safe to

operate without danger or shock. Always perform an AC leakage current check on the exposed metallic parts of the cabinet, such as

screw heads.

Test method for current leakage is described as follow.

(a) Plug the AC line cord directly into rated AC outlet (do not use a line isolation transformer during this check).

(b) Use an AC voltmeter having 5000 ohms per volt or with more sensitivity in the following manner: Connect a 1500 ohms 10

Watt resistor, paralleled by a 0.15UF, AC type capacitor between a known good earth ground (water pipe, conduit, etc.) and

the exposed metallic parts simultaneously. Measure the AC voltage across the combination of 1500 ohms resistor and 0.15UF

capacitor.

(d) Voltage measured must not exceed 0.5 volts RMS. This corresponds to 0.35 milliamp AC. Any value exceeding this limit

constitutes a potential shock hazard and must be corrected immediately.

2-3

PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in this chassis have special safety visual inspections and the protection afforded by them cannot

necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Before replacing any of these

components read the parts list in this manual carefully. The use of substitute replacement parts which do not have the same safety

characteristics as specified in the parts list may create shock, fire, X-RAY radiation or other hazards.

SERVICE NOTES

When replacing parts or circuit boards, clamp the lead wires around terminals before soldering.

When replacing a high wattage resistor (more than 1/2W of metal oxide film resistor) in circuit board, keep the resistor about 10mm

(1/2 in) away from circuit board.

Keep wires away from high voltage or high temperature components.

Keep wires in their original position so as to reduce interference.

When re-assembling the monitor after service, take care to ensure that the degauss coil is not trapped and does not have its

insulation damaged by screws, the metal card tray, or shielding edges.

2-4

HIGH VOLTAGE WARNING

Operation of monitor outside of cabinet or with back removed may cause a serious shock hazard. Work on this model should only be

performed by those who are thoroughly familiar with precautions necessary when working on high voltage equipment.

Exercise care when servicing this chassis with power applied. Many B plus and high voltage terminals are exposed which, if carelessly

contacted, can cause serious shock or result in damage to the chassis. Maintain interconnecting ground lead connections between chassis

and picture tube dag when operating chassis.

Certain HV failures can increase X-ray radiation. Monitor should not be operated with HV levels exceeding the specified rating for

the chassis type. The maximum operating HV specified for the chassis used in this monitor is

24.5KV

1KV

with a line voltage of 120/240 VAC. Higher voltage may also increase possibility of failure in HV supply.

It is important to maintain specified values of all components in the horizontal and high voltage circuits and anywhere else in the monitor

that could cause a rise in high voltage or operating supply voltages. No changes should be made to the original design of the monitor.

Components shown in the shaded areas on the schematic should be replaced with exact factory replacement parts. The use of

unauthorized substitute parts may create a shock, fire or other hazard.

To determine the presence of high voltage, use an accurate, high impedance, HV meter connected between second anode lead and CRT

dag grounding device. When servicing the High Voltage System, remove static charge from it by connecting a 10K ohm resistor in series

with an insulated wire (such as a test probe) between picture tube dag and 2nd anode lead.(AC line cord disconnected from AC power

outlet.)

The picture tube used in this monitor employs integral implosion protection. Replace with tube of the same type number for continue

safety. Do not lift picture tube by the neck. Handle the picture tube only after discharging the high voltage completely.

3. OPERATING INSTRUCTIONS

This procedure gives you instructions for installing and using the 154V/C551 Series display.

Position the display on the desired operation and plug the power cord into a convenient AC outlet. Three-wire power cord must be

shielded and is provided as a safety precaution as it connects the chassis and cabinet to the electrical conduit ground. If the AC

outlet in your location does not have provisions for the grounded type plug, the installer should attach the proper adapter to ensure a

safe ground potential.

Connect the 15-pin color display shielded signal cable to your signal system device and lock both screws on the connector to ensure

firm grounding. The connector information is as follow:

5. CIRCUIT DESCRIPTION

5-1 MICRO CIRCUIT

IC101 is CPU, This CPU has the following functions.

1. Detect timing mode by sensing the horizontal frequency, vertical frequency, the polarity of Hor. Sync and Ver. Sync.

2. Key board scan control.

3. Cs capacitor switch control.

4. Power saving control.

When CPU detects timing, it takes data from E²PROM (IC102), then output voltage to control the geometry of this monitor.

If key is pressed, the CPU will do some job according to the key function. For example, if function key is pressed, it can change different

value to control screen geometry (H-SIZE, V-SIZE...etc.)

5-2 DEFLECTION CIRCUIT

Hor. sync. and ver. sync., come from PC, go into the CPU (IC101). The output goes to the Hor. oscillation and Ver. oscillation processor

(IC401). The IC401 treats sync. signal and output the drive signal to horizontal and vertical output circuit. IC401 also generates some

functions for geometry use, like, horizontal center, vertical size, by I²C bus control, the geometry can be controlled. IC601 is a vertical

output IC to supply the vertical scan. Q404, Q405, Q406 and L405 are the horizontal size controls. Q403 is the horizontal deflection

output, supply the horizontal scan of the monitor. Q707 and Q601 generate the Blanking signal output to G1 of CRT.

Q703 Q704 and Q705 are mute control, brightness control and G1 DC voltage output.

5-3 VIDEO CIRCUIT

IC801 is a video amplifier, clamping signal input from pin No. 11 to restore the DC voltage of video signal, the signal output from IC801

pass through IC802 video package amplifier stage LM2438, then go to the cut off DC restore stage, The video output signal is about

40Vpp.

5-4 POWER SUPPLY

The design uses a discontinuous flyback topology operating in current-mode resulting in a multiple output switcher with stack well. Faster

diodes are used. The fast transient response of the control loop maintains picture integrity. Very fast current limiting protects the switcher

agains short circuits.

UC3842AM (IC901) is the current mode controller selected. It offers feed forward compensation, feedback error amplifier, and low

voltage lock out features. The 3842 draws very little current is start up mode. There is enough power from the line bleeder to slowly charge

a capacitor to the 16 volts needed to start the switcher.

The FET starts a cycle by allowing current to flow into the primary of the power transformer. As current ramps up with time, the voltage

across the current sense resistor (R929) also ramps to a point where the 3842 determines that enough power is stored and turns off the FET.

As the voltage on the transformer reverses, power is dumped from the main power transformer through diodes into the different supplies.

To keep RFI to a minimum and reduce transistor heating, a turn-off snubber network is placed across the FET. Current from the secondary

windings are rectified and filtered to freate the desired voltages. Small high current capacitors quickly return charging current to the source.

Filter inductors remove high frequency noise.
