SERVICE MANUAL

1. SAFETY RECAUTIONS

After re-assembling the product, always perform an isolation

shafts, etc.) to be sure the product is safe to operate without

The surface of the TV screen is coated with a thin film which

can easily be damaged. Be very careful with it when handle

(…Withstand a voltage of 1100V AC (r.m.s.) to an appliance.

method of test requires a test equipment not generally found

Leakage Current Tester”, measure the leakage current from

outlet and repeat each measurement. Any voltage measured
must not exceed 0.75V AC (r.m.s.). This corresponds to 0.5mA

1. The design of this product contains special hardware, many
circuits and components specially for safety purposes. For
continued protection, no changes should be made to the
original design unless authorized in writing by the manufacturer.
Replacement parts must be identical to those used in the
iginal circuits. Service should be　performed by qualified
personnel only.

2. Alterations of the design or circuitry of the products should
not be made. Any design alterations or additions will void
the manufacturer’s warranty and will further relieve the
damage resulting therefrom.

3. Many electrical and mechanical parts in the products have
special safety-related characteristics. These characteristics
are often not evident from visual inspection nor can the
protection afforded by them necessarily be obtained by using
replacement components rated for higher voltage, wattage,
etc. Replacement parts which have these special safety
characteristics are identified in the parts list of service manual.

Electrical components having such features are identified
by shading on the schematics and by (!) on the parts list
ervie manual. The use of a substitute replacent which

does no t have the same safety c haracteristic s as the
recommended replacement part shown in the parts list of
service manual may cause shock, fire, or other hazards.

4. Don’t short between the LIVE side ground and ISOLATED

(NEUTRAL) side ground or EARTH side ground when
repairing. Some model’s power circuit is partly different in

the GND. The difference of the GND is shown by the LIVE:
( ) side GND, ISOLATED (NEUTRAL) : ( ) side GND and
EARTH : ( ) side GND. Don’t short between the LIVEide
GND and ISOLATED (NEUTRAL) side GND or EARTH side
GND and never measure with a measuring apparatus
(os cilloscope etc.) the LIVE side GND and ISOLATED
(NEUTRAL) side GND or EARTH side GND at the same time.
If above note will not be kept, a fuse or any parts will be broken.

5. If any repair has been made to the chassis, it is recommended
that the B1 setting should be checked or adjusted (See
ADJUSTMENT OF B1 POWER SUPPLY).

6. The high voltage applied to the picture tube must conform
with that specified in Service manual. Excessive high voltage
can cause an increase in X-Ray emission, arcing and
possible component damage, therefore operation under
excessi ve high voltage conditions shou ld be kept to a
minimum, or should be prevented. If severe arcing occurs,
remove the AC power immediatelyt and determine the cause
by visual inspection (incorrect installation, cracked or melted
high voltage harness, poor soldering, etc.). To maintain the
proper minimum level of soft X-Ray emission, components
in the high voltage circuitry including the picture tube must
be the exact replacements or alternatives approved by the
manufacturer of the complete product.

7. Do not check high voltage by drawing an arc. Use a high
voltage meter or a high voltage probe with a VTVM. Discharge
the picture tube before attempting meter connect on, by
connecting a clip lead to the ground frame and connecting
the other end of the lead through a 10kΩ 2W resitor to the
anode button.

8. When service is required, observe the original lead dress.
Extra precaution should be given to assure correct lead
dress in the high voltage circuit area. Where a short circuit
has occurred, those components that indicate evidence of
overheating should be replaced. Always use the manufacturer’s
replacement components.

9. Isolation Check (Safety for Electrical Shock Hazard)

check on the exposed metal parts of the cabinet (antenna
terminals, video/audio input and output terminals, Control
knobs, metal cabinet, screwheads, earphone jack, control

danger of electrical shock.

10.

the TV. Should the TV screen become soiled, wipe it with a
soft dry cloth. Never rub it forcefully. Never use any cleaner
or detergent on it.

(1) Dielectric Strength Test
The isolation between the AC primary circuit and all metal
parts exposed to the user, particularly any exposed metal

㩷

part having a return path to the chassis shuld withstand a
voltage of 3000V AC (r.m.s.) for a period of one second

rated up to 120V, and 3000V AC (r.m.s.) to an appliance
rated 200V or more, for a periode of one second.) This

in the service trade.

(2) Leakage Current Check
Plug the AC line cord directly into the AC outlet (do not use
a line isolation transformer during this check.). Using a
“
each exposed metal part of the cabinet, particularly any
exposed metal part having a return path to the chassis, to
a known good earth ground (water pipe, etc.). Any leakage
current must not exceed 0.5mA AC (r.m.s.). However, in
tropical area, this must not exceed 0.2mA AC (r.m.s.).

● Alternate Check Method
Plug the AC line cord directly into the AC outlet ( do not use
a line isolation transformer during this check.). Use an AC
voltmeter having 1000 ohms per volt or more sensitivity in
the following manner. Connect a 1 500Ω 10W resist or
paralleled by a 0.1 5μ F AC -t ype capacitor between an
exposed metal part and a known good earth ground (water
pipe, etc.). Measure the AC voltage across the resistor with
the AC voltmeter. Move the resistor connection to each
exposed metal part, particularly any exposed metal part
having a return path to the chassis, and measure the AC
voltage across the resistor. Now, reverse the plug in the AC

AC (r.m.s.). However, in tropical area, this must not exceed

0.3V AC (r.m.s.). This corresponds to 0.2mA AC (r.m.s.).

8.2 FSCQ-SERIES
FSCQ0765RT GREEN MODE FAIRCHILD POWER SWITCH (FPS™)

Features

● Optimized for Quasi-Resonant Converter (QRC)

● Advanced Burst-Mode Operation for under 1W

Standby Power Consumption

● Pulse-by-Pulse Current Limit

● Over Load Protection (OLP) – Auto estart

● Over Voltage Protection (OVP) – Auto Restart

● Abnormal Over Current Protection (AOCP) – Latch

● Internal Thermal Shutdown (TSD) – Latch

● Under Voltage Lock Out (UVLO) with Hysteresis

● Low Startup Current (typical: 25µA)

● Internal High Voltage SenseFET

● Built-in Soft Start (20ms)

● Extended Quasi-Resonant Switching

Description

A Quasi-Resonant Converter (QRC) typically showslower

EMI and higher power conversion efciency com-pared to
conventional hard-switched converter with axed switching

frequency. Therefore, a QRC is wellsuited for noise-sensitive
applications, such as color TVand audio. Each product in the
FSCQ-Series contains anintegrated Pulse Width Modulation

(PWM) controller anda SenseFET, and is specically designed

for quasi-resonant off-line Switch Mode Power Suppl ie s
(SMPS)with minimal external components.

The PWM controllerincludes an integrated xed frequency

oscillat or, under vol tage lockout , leading edge blankin g
(LEB), optimized gatedriver, internal soft start, temperature­c o mp en s at ed pr e ci s e c ur r e nt s ou rc e s f or a lo o p
compensation, and selfprotection circuitry. Compared with a
discrete MOSFET and PWM controller solution, the FSCQ­Series canreducetota l cost, component count, size, and

weight, whilesimultaneously increasing efciency, productivity,

an d s ys-t em rel iab ilit y. These d evi ces pro vid e a b asi c
platform thatis well suited for cost-effective designs of quasi-

resonantswitching yback converters.

High voltage power SenseFET drain connection.

This pin is the control ground and the SenseFET source.

This pin is the positive supply input. This pin provides internal operating current for both

start-up and steady-state operation.

This pin is internally connected to the inverting input of the PWM comparator.

The collector of an optocoupler is typically tied to this pin. For stable operation, a capacitor

should be placed between this pin and GND. If the voltage of this pin reaches 7.5V, the over

load protection triggers, which results in the FPS shutting down.

This pin is internally connected to the sync detect comparator for quasi-resonant switching.

In normal quasi-resonant operation, the threshold of the sync comparator is 4.6V/2.6V.

Whereas, the sync threshold is changed to 3.0V/1.8V in an extended quasi-resonant operation.

Note:

1. Usually the yback voltage is slightly more than 2 x VS. This must be taken into consideration when settingVS.

2. Versus pin 4.

3. V3 is higher than VS during the rst half of the yback pulse.

4. Such repetitive output peak currents are usually observed just before and after the yback pulse.

5. This non-repetitive output peak current can be observed, for example, during the Switch-On/Switch-Off phases. This

peak current is acceptable providing the SOA is respected (Figure8 and Figure9).

6. All pins have a reverse diode towards pin 4, these diodes should never be forward-biased.

7. Input voltages must not exceed the lower value of either VS + 2 or 40 volts.
