Important safety notice
Special components are used in this projection television which are important for safety. These components are
identified on the schematic diagram by the symbol
and printed in BOLD TYPE on the replacement part list. It is
essential that these critical parts are replaced with the manufacturer’s specified replacement part to prevent x-ray
radiation, shock, fire or other hazards. Do not modify the original design without the manufacturer’s permission.
Safety precautions
General guidelines
An isolation transformer should always be used
during the servicing of a PTV whose chassis is not
isolated from AC power line. Use a transformer of
adequate power rating as this protects the technician
from accidents resulting in personal injury from
electrical shocks. It will also protect the PTV from being
damaged by accidental shorting that may occur
during servicing.
When servicing, observe the original lead dress,
especially in the high voltage circuit. Replace all
damaged parts (also parts that show signs of
overheating.)
Always replace protective devices, such as
fishpaper, isolation resistors and capacitors, and
shields after servicing the PTV. Use only
manufacturer’s recommended rating for fuses, circuits
breakers, etc.
High potentials, as high as 32.5kV, are present when
this PTV is operating. Operation of the PTV without the
rear cover introduces danger for electrical shock.
Servicing should not be performed by anyone who is
not thoroughly familiar with the necessary precautions
when servicing high-voltage equipment.
Extreme care should be practiced when handling the
picture tube. Rough handling may cause it to implode
due to atmospheric pressure. (14.7 lbs. per sq. in.). Do
not nick or scratch the glass or subject it to any undue
pressure. When handling, use safety goggles and
heavy gloves for protection. Discharge the picture
tube by shorting the anode to chassis ground (not to
the cabinet or to other mounting hardware). When
discharging connect cold ground (i.e. DAG ground
lead) to the anode with a well insulated wire or use a
grounding probe.

TO INSTRUMENT’S
EXPOSED METAL
PARTS
The front area (between the projection tube and the
lens) is enclosed by a metal box to ensure positive
safety during normal and abnormal conditions when
checking and repairing. To fully ensure safety, the
following precautions must be observed.
1. Do not remove the lens or metal box.
2. Make sure to turn the power OFF when the lens is
removed or when checking the cleanliness of the
lens.
3. Do not remove the lens or metal box to check the
projection tube for operation by watching it directly.
Use a mirror or paper to view the image.
Before returning a serviced PTV to the owner, the
service technician must thoroughly test the unit to
ensure that is completely safe to operate. Do not use a
line isolation transformer when testing.
1500Ω,10W
Figure 1. Hot check circuit
Insulation test
Connect an insulation tester between an exposed
metallic part and AC line.
Apply 1080VAC/60Hz for 1 second. Confirm that the
current measurement is 0.5mA ~ 2.0mA. Repeat test
with other metallic exposed parts.
X-ray radiation
WARNING: The potential source of x-ray radiation in the
PTV is in the high voltage section and the picture tube.
Note: It is important to use calibrated equipment.
Apply all black video signals (1080i) and confirm high
voltage measures 31.5 ± 1.0kV. If the high voltage is
not within the range, change C514 to 1800pF, 2000pF,
2400pF or 2700pF until the desired value is obtained.
Apply NTSC white pattern and confirm the high voltage
measures 30.1 ± 1.5kV.
Apply HD 1080I white pattern and confirm the high
voltage measures 30.1 ± 1.5kV
Leakage current cold check
Unplug the AC cord and connect a jumper between the
two plug prongs. Press the POWER switch ON.
Measure the resistance between the jumpered AC plug
and expose metallic parts such as screw heads,
Service Manual
antenna terminals, control shafts, etc. If the exposed
metallic part has a return path to the chassis, the
reading should be between 240kΩ and 5.2MΩ. If the
exposed metallic part does not have a return path to
the chassis, the reading should be infinite.
Leakage current hot check (see figure 1)
Plug the AC cord directly into the AC outlet. Do not use
an isolation transformer during the check.
Connect a 1.5kΩ 10 watt resistor in parallel with a
0.15µF capacitor between and exposed metallic part
and ground. Use earth ground, for example a
water pipe.
Using a DVM with a 1000 ohms/volt sensitivity or
higher, measure the AC potential across the resistor.
Repeat the procedure and measure the voltage
present with all other expose metallic parts.
Verify any potential does not exceed 0.75 volt RMS. A
leakage current tester (such a Simpson model 229,
Sencore model PR57 or equivalent) may be used in
the above procedure, in which case any current
measure must not exceed 0.5 milliamp. If any
measurement is out of the specified limits, there is a
possibility of a shock hazard and the PTV must be
repaired and rechecked before it is returned to
the customer.

About lead free solder (PbF)
Note: Lead is listed as (Pb) in the periodic table of elements.
In the information below, Pb will refer to Lead solder, and PbF will refer to Lead Free Solder.
The Lead Free Solder used in our manufacturing process and discussed below is (Sn+Ag+Cu).
That is Tin (Sn), Silver (Ag) and (Cu) although other types are available.
This model uses Pb Free solder in it’s manufacture due to environmental conservation issues. For
service and repair work, we’d suggest the use of Pb free solder as well, although Pb solder may be
used.
PCBs manufactured using lead free solder will have the PbF within a leaf symbol
back of PCB.
stamped on the
Caution
• Pb free solder has a higher melting point than standard solder. Typically the melting
point is 50 ~ 70 °F (30 ~ 40 °C) higher. Please use a high temperature soldering iron
and set it to 700 ± 20 °F (370 ± 10 °C).
• Pb free solder will tend to splash when heated too high (about 1100 °F or 600 °C).
If you must use Pb solder, please completely remove all of the Pb free solder on the
pins or solder area before applying Pb solder. If this is not practical, be sure to heat the
Pb free solder until it melts, before applying Pb solder.
• After applying PbF solder to double layered boards, please check the component side
for excess solder which may flow onto the opposite side. (see figure below)

Service notes
Note: These components are affixed with glue. Be careful not to break or damage any foil under the
component or at the pins of the ICs when removing. Usually applying heat to the component for
a short time while twisting with tweezers will break the component loose.
Leadless chip component
(surface mount)
How to replace Flat-IC
Chip components must be replaced with identical chips
due to critical foil track spacing. There are no holes in
the board to mount standard transistors or diodes.
Some chip capacitor or resistor board solder pads may
have holes through the board, however the hole
diameter limits standard resistor replacement to 1/8
watt. Standard capacitor may also be limited for the
same reason. It is recommended that identical
components be used.
Chip resistor have a three digit numerical resistance
code - 1st and 2nd significant digits and a multiplier.
Example: 162 = 1600 or 1.6kΩ resistor, 0 = 0Ω (jumper).
Chip capacitors generally do not have the value
indicated on the capacitor. The color on the component
indicates the general range of the capacitance.
Chip transistors are identified by a two letter code. The
first letter indicated the type and the second letter, the
grade of transistor.
Chip diodes have a two letter identification code as per
the code chart and are a dual diode pack with either
common anode or common cathode. Check the parts
list for correct diode number.

4. Position the new flat IC in place (apply the pins of
the flat IC to the soldering pads where the pins
need to be soldered). Properly determine the
positions of the soldering pads and pins by
correctly aligning the polarity symbol. Start aligning
and soldering Pin No.1, then align and solder the
pin in the apposite corner of the IC, this will help to
align the rest of the pins.
Chip component installation
1. Put a small amount of solder on the board
soldering pads.
2. Hold the chip component against the soldering
pads with tweezers or with a miniature alligator clip
and apply heat to the pad area with a 30 watts iron
until solder flows. Do not apply heat for more than
3 seconds.

Service notes (continued)
IMPORTANT: To protect against possible damage to
the solid state devices due to arcing or static discharge,
make certain that all ground wires and CRT DAG wire
are securely connected.
CAUTION: The power supply circuit is above earth
ground and the chassis cannot be polarized. Use an
isolation transformer when servicing the PTV to avoid
damage to the test equipment or to the chassis.
Connect the test equipment to the proper ground (( )
or ( )) when servicing, or incorrect voltages will
be measured.
WARNING: This PTV has been designed to meet or
exceed applicable safety and x-ray radiation protection
as specified by government agencies and independent
testing laboratories.
To maintain original product safety design standards
relative to X-ray radiation and shock and fire hazard,
parts indicated with the symbol
on the schematic
must be replaced with identical parts. Order parts from
the manufacturer’s parts center using the parts
numbers listed in this service manual, or provide the
chassis number and the part reference number.
For optimum performance and readability, all other
parts should be replaced with components of
identical specification.

Auto diagnosis feature
This receiver incorporates a new auto-diagnosis
feature. With this new feature will be easier for the
technicial to detect the failures. There is a LED located
by the keyboard on the front panel, this LED will start
flashing when a failure is detected by the circuits
located in specific areas, depending on how many
times the LED is flashing, this will tell you what circuit
should be checked.
Make a count of flashing and see Table 3.
Please use this feature effectively especially for

Convergence alignment template
The convergence alignment template is a grid
approximately the size of the viewing screen used to
ensure the proper size and shape of the alignment
rasters. It is 6 blocks across by 6 blocks high. The grid
dimensions vary with the mode of operation.
Apply a convergence alignment template to the
viewing screen of the PTV. Make sure the center lines
are properly aligned. If a template is not available, one
can be created by following the instructions below.
Create a convergence alignment template by
drawing a pattern, as in figure 59, in the actual
dimensions on transparent film or tracing paper. Start
with the Horizontal and Vertical Center Axis and work
outwards until the pattern is complete. Pay attention to
the actual dimensions of the pattern.
Grid dimensions:

the colors become in balance.
5. Adjust R-Y_A so red look natural, and rest of the
colors become in balance.
6. Check that white bar is real white, no bluish or
redish or tending to become grey.
Service Manual
- 46 -
Service mode (electronic controls, continued)
Red, green & blue screen cutoff
Color check
1. Use either a no input signal condition or raster from
the NTSC generator.
2. Observing the green tube directly or via a reflective
surface, adjust the VR on focus pack for the green
tube for minimum noise.
3. Adjust the noise level in the red and blue tubes to
match the noise level in the green tube.
Using a clean RF or video signal, set the color level so
that it does not saturate or appear harsh. Make sure
that color is not set so that it appears dull and washed
out. Look for natural colors, try to adjust the picture to
appear as a normal photograph.
White balance adjustment
Note:
1080I, 480p, 480I pattern can be obtained from
Panasonic’s TU-DST51 set-top box DTV
decoder.
Prior to this adjustment, perform sub-contrast
adjustment. This adjustment requires that the service
use skills in observing what a screen without color
should look like (white picture).
1. Enter the service mode.
2. Apply a NTSC black and white pattern to one of the
video inputs (see above note) color bar with no
color.
High light white balance adjustment
1. Adjust DAC R_DR for red and B_DR for blue
adjustments.
2. Make sure the screen is not blue or green. The
screen should be white in the white area.
3. Check the black and white area for a black and
white picture with even shades of gray and no color
tint in the picture.
Low light white balance adjustment
1. Adjust DAC CUT_R for red and DAC CUT_B for
blue.
2. Check the screen for even white in all areas, no
color.
3. Check the black and white pattern for a black and
white picture, even shades of gray and no color tint
in the low light areas.
4. Repeat the High Light and Low Light White
Balance again until the white balance tracks from
high light to low light.
Tint and color check
Set picture mode to VIVID mode.
Again, the service ability to see color and the balance
of color is important for theses adjustments.
Tint check
1.
2.
3.
4.
In picture menu set PICTURE NORM to YES.
Apply color bars to the video input.
Magenta is composed of two colors, blue and red.
Check to see that magenta does not have too
much blue or too much red.
5. Check cyan. Cyan is composed of blue and green.
It should not have too much blue or green.
6. Use a test signal from a VCR or laser disk that has
a pre-recorded close up of a signal that has good
flesh tones.
7. The signal on the VCR or laser disk should look
normal.
MTS circuit adjustments
Note:
It is important to adjust the MTS circuit in the
order shown below.
The MTS circuit adjustments require two steps:
1. Input level adjustment.
2. Stereo separation adjustment.
Input level adjustment (MTSIN)
Preparation:
1. Connect an RMS meter (AC range) with filter jig as
shown in figure 64 .
RMS
METER

Note: Set the 30% modulation with the P.L and
N.R. switches OFF then turn them ON while
testing.
5. Adjust MTS High-Level Separation “SEPAH” DAC
data until the amplitude of the waveform measured
on the scope is minimum.
6. Repeat above steps 2 through 5 until the amplitude
is at minimum for both signals.
Clock Adjustment (CLOCK)
Preparation:
Connect the frequency counter from IC001 MPU
Pin 10 or TPA009, to cold ground (
).
Note:
Frequency Counter probe capacitance should
be 8pF or less.
Procedure:
1. Turn the PTV “ON” with the AC power applied.
2. Measure TPA009 IC001 MPU pin 10 for frequency
and record the reading.
Note:
Pin 10 measurement must have at least four
digits of resolution following the decimal point.
Example: 000.0000
3. Place the PTV into service mode for making
electronic adjustment, select the clock adjustment
DAC CLOCK and change value to 128.
4. Calculate and set CLOCK based on the
following formula:
{ 732.422 Ð- p in ( 10 ) [ Hz ] }
CLOCK = 128 + 0.450x106x -----------------------------------------------------------732.4220
Note:
Pin 10 measurement will not change
regardless of the value stored in CLOCK.

MEDICIÓN DE VOLTAJES
1.
Medición de voltaje:
-
-
-
El voltaje de entrada al Receptor es de
120V de Corriente Alterna. Un
generador de patrones con formato
NTSC se conecta a la entrada de la
antena. (Patrón de Barras de Colores
con 100 IREs para el Blanco y 7.5 IREs
para el Negro.)
Los ajustes de los Menus Picture y
Audio se normalizan.
En el Menú Set-Up, en la opción
ANTENA, se selecciona el modo de
CABLE.
El nivel de Volumen se minimiza.
De los modos TV y Video, seleccionar el
modo TV.
Seleccionar modo Estereo del Audio.
2.
Las mediciones de los voltajes son
nominales y pueden variar hasta
10%
en
componentes
en
funcionamiento. Las lecturas de los
voltajes pueden variar por la
potencia de la señal y el contenido
de la imagen.
Las fuentes de voltajes son
nominales.
El símbolo indica el tipo de tierra que
se utiliza en la conexión del medidor.
PRECAUCION: SI no se utiliza la
conexión a la tierra adecuada, se
obtendrán mediciones equivocadas y
podría dañar el equipo de medición.
MEDICIÓN DE FORMAS DE ONDA

PARTS LIST
1. Un símbolo como
indica el punto para medir
una señal. (La medición puede hacerse en
el punto con mayor accesibilidad, siempre
que sea común al indicado.)
2. Se midieron utilizando un generador con
formato NTSC conectado a la terminal de la
antena. (Patrón de 8 Barras de Colores
EAI, formato NTSC de 100 IREs para el
Blanco y 7.5 IREs para el Negro.)
3. Los ajustes de usuario de los Menus
PICTURE y AUDIO se normalizaron.
Posteriormente el nivel de volumen se
ajusta al mínimo.
4. Las formas de onda de Video y Color
fueron tomadas con un osciloscopio de
banda alta y con un punta de prueba de
baja capacitancia (10 a 1). La forma y
amplitud de las ondas puede variar
según el tipo de osciloscopio que se
utilice y sus características.
5. El símbolo de tierra que aparece junto al
número de la forma de onda, indica que
se utiliza conexión a Tierra Caliente en
el extremo negativo de la punta de
prueba.
