ELECTROSTATICALLV SENSITIVE (ES) DEVICES
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly
are called Electrostatically Sensitive (ES) Devices. Examples of typical
ES devices are integrated circuits and some
field effect transistors and semiconductor "chip" components. The following techniques should be used to help
reduce the incidence of component damage caused by static electricity.
1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off
any electrostatic charge on your body by touching a known earth ground. Alternatively, obtain and wear a
commercially available discharging wrist strap device, which should be removed for potential shock reasons
prior to applying power to the unit under test.
2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface
such as aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly.
3. Use only a grounded-tip soldering iron
to solder or unsolder ES devices.
4. Use only an anti-static solder removal device. Some solder removal devices not classified as "anti-static" can
generate electrical charges sufficient to damage ES devices.
5. Do not use freon-propelled chemicals. These can generate electrical change sufficient to damage ES devices.
6. Do not remove a replacement ES device from its protective package until immediately before you are ready to
install it. (Most replacement ES devices are packaged with leads electrically shorted together by conductive
foam, aluminum foil or comparable conductive material.)
7. Immediately before removing the protective material from the leads of a replacement ES device, touch the
protective material to the chassis or circuit assembly into which the device will be installed.
CAUTION:
Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion
such as the brushing together oryour clothes fabric or the lifting of your foot from a carpeted floor can generate
static electricity sufficient to damage an ES device.)
PRODUCT SAFETY NOTICE
Each precaution in this manual should be followed during servicing.
Components identified with the IEC symbol A
in the parts list are of special significance to safety. When
replacing a component identified with A ,use only the replacement parts designated, or parts with the
same ratings or resistance, wattage, or voltage that are designated
in the parts list in this manual.
Leakage -current or resistance measurements must be made to determine that exposed parts are
acceptably insulated from the supply circuit before returning the product to the customer.

LEAKAGE TEST (FOR SERVICE ENGINEERS IN THE U.S.A.)
Before returning the unit to the user, perform the following safety checks:
1. Inspect all lead dress to make
certain that leads are not pinched
or that hardware is not lodged be-
tween the chassis and other
SIMPSON MODEL 229 ETC. FOR
LEAKAGE TEST
metal parts in the unit. TO EACH EXPOSED
2. Be sure that any protective de-
vices such as nonmetallic control
knobs, insulating fishpapers,
cabinet backs, adjustment and
METAL SURFACE OF -------1
UNIT UNDER TEST
compartment covers or shields,
isolation resistor-capacity net-
works,
mechanical insulators,
etc. Which were removed for ser-
vicing are properly reinstalled.
3. Be sure that no shock hazard exists; check for leak-
age current using Simpson Model 229 Leakage
Tester, standard equipment item No. 21641, RCA
Model WT540A or use alternate method as follows:
Plug the power cord directly into a 120-volt
AC re-
ceptacle (do not use an Isolation Transformer for
this test). Using two clip leads, connect a 1500
Ohm, 10-watt resistor paralleled by a 0.15µF ca-
pacitor,
in series with all exposed metal cabinet
parts and a known earth ground, such as a water
pipe
or conduit. Use a VTVM or VOM with 1000
Ohms per volt, or higher sensitivity to measure the
HIGH

AC voltage drop across the resistor. (See Diagram.) TO EXPOSED
Move the resistor connection to each exposed METAL PARTS
metal part having a return path to the chassis (an-
tenna, metal, cabinet, screw heads, knobs and con-
trol shafts, escutcheon, etc.) and measure the
AC
voltage drop across the resistor. (This test should
be performed with the power switch
in both the On
and Off positions.)

A reading of 0.35 volt RMS or more is excessive and indicates a potential shock hazard which must be corrected
before returning the unit

2. FLD segment illumination
This service procedure will illuminate all segments by the following steps :
With the POWER ON, press the "FM/AM(TUNER)" button while pressing the "MEMO" button for
at least 3 seconds or more. This procedure takes 1 minute and 40 seconds to finish; at this point
the procedure is complete.
1. All segments will be illuminated for 5 seconds.

CIRCUIT DESCRIPTION
1. SURROUND CIRCUIT
This model incorporates a surround processor circuit that provides 6 types of the surround sound. Fig. 1-1 is a block diagram
of the surround processor circuit.
The microprocessor transfers the data to the parameter control ( Serial data, Serial clock, Request Ready ) to operate the
circuits in each mode.

(2) THX Cinema
The IC 0602 (LC83017E) is a THX Cinema decoder IC.
IC 0602 (LC83017E) divides the 4 channel signals
(Left, Right, Center and Surround) sourcing from IC
Q601 (LC83016E) into 6 channel signals (Left, Right,
Center,
Surround Left, Surround Right and Sub
Woofer).

(3) Dolby pro logic
Q601 ( LC8316E) is a Dolby pro logic decoder IC.
When an audio signal recorded using the Dolby pro
logic system is sent to this IC, the left, right, center
and surround components are separated. The
surround signal component is delayed by the digital
delay circuit by 15-30
mS and is sent to the modified
B-type decoder Q601 where noise reduction pro-
cessing is performed.
(4) Movie, 3CH Logic Hall, Matrix
The Movie mode provides the feeling of presence
you get from a 35-mm movie in a movie theater.
3CH Logic mode is used to improve the sound field
center by applying directivity enhancement provided
by the Dolby Pro Logic Surround decoder.
Hall mode provides a sound-field effect of medium-
sized circular hall with rich reverberations.
Matrix mode is effective for playing sports broad-
casts or outdoor live concerts.
It provides a surround
mode with a wide surround effect.
All the connections of the circuits are the same in
these modes. Q601, controlled by the microproces-
sor, processes the audio signals to produce various
sound effects and creates surround components to
use them as signals to drive the surround channel.
2. CENTER MODE
With Dolby pro logic, three center modes depend on the
use of a center speaker as follows :
NORMAL : Bass frequencies are sent only to the
Left and Right Front channels. Select
this mode when the Center Speaker is
smaller than the Left and Right speakers.
WIDE : Bass frequencies are sent to the Left,
Center and Right speakers. Select this
mode when the Center speaker is
approximately the same size as the Left
and Right speakers.
PHANTOM : Center channel information is sent to the
Left and Right speakers. Select this
mode when you do not have a center
channel speaker.

3. TEST TONE GENERATOR
The test tone generator generates a test tone ( noise ) to
check the balance of sound output from each speaker in
the THX CINEMA MODE, ( This circuit is produced under
license of Lucasfilm Ltd. ) and the Dolby pro logic mode.
