SAFETY PRECAUTIONS
IMPORTANT SAFETY NOTICE
Many electrical identify these parts and mechanical parts in this chassis have special
safety-related characteristics! In the Schematic Diagram and Replacement Parts List.
It is essential that these special safety parts should be replaced with the same
components as recommended in this manual to prevent X-RADIATION, Shock, Fire,
or other Hazards.
Do not modify the original design without permission of the manufacturer.
General Guidance
An Isolation Transformer should always be used during the servicing of a receiver
whose chassis is not isolated from the AC power line. Use a transformer of adequate
power rating as this protects the technician from accidents that might result in
personal injury caused by electrical shocks.
It will also protect the receiver and it’s components from being damaged by
accidental shorts of the circuitry that might be inadvertently introduced during the
service operation.
If any fuse (or Fusible Resistor) in this TV receiver is blown, replace it with a specified
one.
When replacing a high wattage resistor (Oxide Metal Film Resistor, over 1W), keep
3
the resistor 10mm away from PCB.
Keep wires away from high voltage or high temperature parts.
Due to the high vacuum and large surface area of the picture tube, extreme care
should be taken in handling the Picture Tube. Do not lift the Picture Tube by its Neck.
X-RAY Radiation
Warning:
The source of X-RAY RADIATION in this TV receiver is the High Voltage Section and
the Picture Tube.
For continued X-RAY RADIATION protection, the replacement tube must be of the
same type as specified in the Replacement Parts List.
Before returning the receiver to the customer,
Always perform an AC leakage current check on the exposed metallic parts of the
cabinet, such as antennas, terminals, etc., to make sure that the set is safe to
operate without any danger of electrical shock.

2. Test high voltage only by measuring it with an appropriate high voltage meter or
other voltage-measuring device (DVM, FETVOM, etc.) equipped with a suitable
high voltage probe. Do not test high voltage by “drawing an arc”.
3. Discharge the picture tube anode only by (a) first connecting one end of an
insulated clip lead to the degaussing or kine aquadag grounding system shield at
the point where the picture tube socket ground lead is connected, and then (b)
touch the other end of the insulated clip lead to the picture tube anode button,
using an insulating handle to avoid personal contact with high voltage.
4. Do not spray chemicals on or near this receiver or any of its assemblies.
5. Unless specified otherwise in this service manual, clean electrical contacts only by
applying the following mixture to the contacts with a pipe cleaner, cotton-tipped
stick or comparable nonabrasive applicator; 10% (by volume) Acetone and 90%
(by volume) isopropyl alcohol (90%-99% strength)
CAUTION: This is a flammable mixture.
Unless specified otherwise in this service manual, lubrication of contacts is not
required.
6.
Do not defeat any plug / socket B+ voltage interlocks with which receivers
covered by this service manual might be equipped.
7. Do not apply AC power to this instrument and/or any of its electrical assemblies
unless all solid-state device heat sinks are correctly installed.
8. Always connect the test receiver ground lead to the receiver chassis ground
before connecting the test receiver positive lead.

Electrostatic ally Sensitive (ES) Devices
Some semiconductor (solid state) devices can be damaged easily by static electricity.
Such components are usually called Electrostatic ally 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 semiconductorequipped 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 to prevent potential
shock 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 type folder 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 charges
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 even some normally harmless motions such as mutual brushing of
your clothes’ fabric or lifting of your foot from a carpeted floor might generate static
electricity sufficient to damage an ES device.)
General Soldering Guidelines
1. Use a grounded-tip, low-wattage soldering iron and appropriate tip size and
shape that will maintain tip temperature within the range of 500 oF to 600 oF.
2. Use an appropriate gauge of RMA resin-core solder composed of 60 parts tin/40
parts lead.
7
3. Keep the soldering iron tip clean and well tinned.
4. Thoroughly clean the surfaces to be soldered. Use a mall wire bristle (0.5 inch, or
1.25cm) brush with a metal handle. Do not use freon-propelled spay-on cleaners.
5. Use the following unsoldering technique
a. Allow the soldering iron tip to reach normal temperature. (500 o F to 600o F)
b. Heating the component lead until the solder melts.
c. Quickly draw the melted solder with an anti-static, suction-type solder removal
device with solder braid.
CAUTION: Work quickly to avoid overheating the circuit board printed foil.
6. Use the following unsoldering technique
a. Allow the soldering iron tip to reach normal temperature. (500 o F to 600o F)
b. First, hold the soldering iron tip and solder the strand against the component
lead until the solder melts.
c. Quickly move the soldering iron tip to the junction of the component lead and
the printed circuit foil, and hold it there only until the solder flows onto and
around both the component lead and the foil.
CAUTION: Work quickly to avoid overheating the circuit board printed foil.
d. Closely inspect the solder area and remove any excess or splashed solder
with a small wire-bristle brush.
Remove /Replacement
Some chassis circuit boards have slotted holes (oblong) through which the IC leads
are inserted and then bent flat against the circuit foil. When holes are of slotted type,
the following technique should be used to remove and replace the IC. When working
with boards using the familiar round hole, use the standard technique as outlined.
Removal
Desolder and straighten each IC lead in one operation by gently prying up on the
lead with the soldering iron tip as the solder melts.
Draw away the melted solder with an anti-static suction-type solder removal device
(or with solder braid) before removing the IC.
Replacement
Carefully insert the replacement IC in the circuit board.
Carefully bend each IC lead against the circuit foil pad and solder it.
Clean the soldered areas with a small wire-bristle brush. (It is not necessary to
reapply acrylic coating to the areas).
“Small-Signal” Discrete Transistor
Removal/Replacement
8
Remove the defective transistor by clipping its leads as close as possible to the
component body.
Bend into a “U” shape the end of each of three leads remaining on the circuit board.
Bend into a “U” shape the replacement transistor leads.
Connect the replacement transistor leads to the corresponding leads extending from
the circuit board and crimp the “U” with long nose pliers to insure metal to metal
contact then solder each connection.
Power Output, Transistor Device
Removal/Replacement
Heat and remove all solder from around the transistor leads.
Remove the heat sink mounting screw (if so equipped).
Carefully remove the transistor from the heat sink of the circuit board.
Insert new transistor in the circuit board.
Solder each transistor lead, and clip off excess lead.
Replace heat sink.
Diode Removal/Replacement
Remove defective diode by clipping its leads as close as possible to diode body.
Bend the two remaining leads perpendicularly to the circuit board.
Observing diode polarity, wrap each lead of the new diode round the corresponding
lead on the circuit board.
Securely crimp each connection and solder it.
Inspect (on the circuit board copper side) the solder joints of the two “original” leads.
If they are not shiny, reheat them and if necessary, apply additional solder.
Fuse and Conventional Resistor
Removal/Replacement
1. Clip each fuse or resistor lead at top of the circuit board hollow stake.
2. Securely crimp the leads of replacement component around notch at stake top.
3. Solder the connections
CAUTION: Maintain original spacing between the replaced component and
adjacent components and the circuit board to prevent excessive component
temperatures.
Circuit Board Foil Repair
Excessive heat applied to the copper foil of any printed circuit board will weaken the
adhesive that bonds foil to the circuit board causing the foil to separate from or
“lift-off” the board. The following guidelines and procedures should be followed
9
whenever this condition is encountered.
At IC Connections
To repair a defective copper pattern at IC connections use the following procedure to
install a jumper wire on the copper pattern side of the circuit board. (Use this
technique only on IC connections).
1. Carefully remove the damaged copper pattern with a sharp knife. (Remove only
as much copper as absolutely necessary).
2. Carefully scratch away the solder resist and acrylic coating (if used) from the end
of the remaining copper pattern.
3. Bend a small “U” in one end of a small gauge jumper wire and carefully crimp it
around the IC pin. Solder the IC connection.
4. Route the jumper wire along the path of the out-away copper pattern and let it
overlap the previously scraped end of the good copper pattern. Solder the
overlapped area and clip off any excess jumper wire.
At other connections
Use the following technique to repair the defective copper pattern at connections
other than IC Pins. This technique involves the installation of a jumper wire on the
component side of the circuit board.
1. Remove the defective copper pattern with a sharp knife.
Remove at least 1/4 inch of copper, to insure that a hazardous condition will not
exist if the jumper wire opens.
2. Trace along the copper pattern from both sides of the pattern break and locate the
nearest component that is directly connected to the affected copper pattern.
3. Connect insulated 20-gauge jumper wire from the lead of the nearest component
on one side of the pattern break to the lead of the nearest component on the other
side.
Carefully crimp and solder the connections.
CAUTION: Be sure the insulated jumper wire is dressed so that it does not touch
components or sharp edges.

2. Analysis of common path circuits
High frequency television signals, received via an antenna (or transmitted
through a cable TV system) to the input terminal of the high frequency tuner
A101, are processed for tuning and high frequency amplifying and mixing, then a
38.9MHz image intermediate frequency and 34.4MHZ and intermediate
frequency signal will be released at the IF terminal of Z101 to b of the transistor
V101 , where signals are amplified to compensate for the insertion losses of the
sound surface wave filter. Single or dual-ended input is used for the sound
surface wave filters Z101 of this appliance according to system properties.
Intermediate frequency signals will be transmitted to (41) and (42) of
N204(TMP8803SN). The mixed signals of picture video signals and secondary
sound intermediate frequency signals output from (31) of N204, After sound
carrier frequency is trapped by the trap filter, intermediate frequency signals are
amplified and PLL image decoded, The AGC time constant is dependent on
C205 (0.22u) connected to (39) of N204 (TMP8803SN),.
3.Analysis of sound power amplifying circuits
Sound power amplifying circuits are composed of integrated circuitsTDA2611 and
peripheral components. TDA2611 is an integrated electrical circuit . Information
introducing functions and testing data for TDA2611 maintenance is listed in Table 4. T
if a cylindrical color card is installed then a fluke III digital multimeter is used.

3. Analysis of vertical sync and vertical scan output circuits
The field sync signals segregated from compound sync signals are used to
activate the vertical frequency segregation system which commences when a set
amount of vertical sync pulse signals are tested. Of the sync pulse frequencies
obtained from segregation, some are transmitted to the vertical tooth wave
generator. The vertical frequency tooth wave, after geometric processing, is
transmitted from (16) of N204 (TMP8803SN) to (5) of vertical scan output IC
N402 (LA7840). The external resistor R443 (5.6KΩ) of N204 (16) provides a
reference current to the vertical tooth wave generator. The external capacitor
C244 (0.1uF) of pin (2) forms the vertical ramp wave. The vertical ramp wave is
sending the pin (4) of the vertical scan output integrated circuit N402 that is a
complete bridge current drive output circuit. After shaped and amplified the
vertical ramp wave is output from pin (2) of N402.
Information introducing functions and testing data for LA7840 maintenance is
listed in Table 4. if a cylindrical color card is installed then a fluke III digital
multimeter is used.

4. Analysis of horizontal sync and horizontal scan output circuits
As the horizontal oscillation circuit is installed inside N204 (TMP8803SN), . Some
18
brightness signals including compound sync signals are transmitted to the
internal sync segregation circuits, where horizontal sync and vertical sync pulses
are segregated. R321 (10K), R462 (12K) C452 (3900pF) VD436 and T402 are
connected to N204 (13) are phase-lock loop filters. Horizontal pumping signals
are transmitted from (13) of N204 to horizontal promotion transistor V444
(2SC2383), and then drive the H-DRIVE transformer. After being amplified
through it switches power transistor V411 (2SD2499) to control the horizontal
scan of the electronic-beam.C412 is a horizontal S correction capacitor and L414
is for horizontal linear inductor. T402 is a horizontal output transformer. The
horizontal return pulse output from (8) of T402 is transmitted to pin (27) of N204
who controls ABL circuits. ABL avoid high-voltage over rated value that will cause
X-ray and affect your health.
5. Analysis of video amplifying circuits
The video amplifying circuits are comprised of V601, V611, V621 and peripheral
components. B, G and R signals output from N204 (50), (51) and (52), 3 video
power transistor are available for amplifying the input R, G, B. White balance
adjustment is completed through N901 under control of an I2C serial bus control
system.
6. Analysis of switching mode power circuits
The installed switching mode power source is a typical autonomous pulse switch
power source. The circuits are comprised of switching transistor V513, switching
mode transformer T501, bridge-rectifier components. When the switch is set to
on, the pulse voltage of the 220V voltage rectified by VD501 rectifier is filtered by
the capacitor C507 (150uF) to obtain +300V direct current, which is added
through (3)-(4) of the switching mode transformer T501 to the collective polar of
switching transistor V513 (2SC4584). V503, Primary coil 3-7 and feedback coil
1-2 form a self-actuated oscillator. When the appliance is first switched on.
Some 560Vp-p voltage oscillating pulses will come into being and the duty ratio is
controlled by C515. The shut down time of V513 is controlled by V512. The
current passed V512 is larger and the operating time of V513 is shorter and the
output voltage is smaller. The coupler VD515 (PC817B inlet) functions to control
voltage, and the voltage tolerance information from RP501 and V506 are
transmitted to V501 to control the switch velocity and hold the output voltage
normal.
The pulse voltage output from the secondary (12) of the switching mode
transformer T501, rectified and filtered by VD556 and C563 is +110V direct
current voltage which is the main voltage. The pulse voltage output from (13) is
rectified and filtered by VD555 and C561 and the resultant +180V direct current
voltage is supplied. The pulse voltage output from (16) is rectified and filtered by
VD516 and C552 and the resultant +19V direct current voltage is supplied to the
sound power amplifying circuits. The pulse voltage output from (15) is rectified
19
and filtered via VD515 and C542 to obtain +25V direct current voltage to supply
the vertical scan IC. The pulse voltage output from (14) is rectified and filtered via
VD513 and C532 to obtain +15V direct current voltage. +12V direct current
voltage output from N506 (3), after rectification of the secondary source, +9V and
+5v are supplied to the decoder chip. And CPU. The voltage of VT comes from
the main voltage.
