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,suchas
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.
X-ray precautions
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.
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,
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 1.5kΩ10 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.
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

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” or a leaf symbol stamped on the
back of PCB.
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 °For600°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)
Suggested Pb free solder
There are several kinds of Pb free solder available for purchase. This product uses Sn+Ag+Cu
(tin, silver, copper) solder. However, Sn+Cu (tin, copper), Sn+Zn+Bi (tin, zinc, bismuth) solder
canalsobeused.

Service notes
Leadless chip component
(surface mount)
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 1.6kΩresistor, 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.
Component removal
1. Use solder wick to remove solder from component
end caps or terminal.
2. Without pulling up, carefully twist the component
with tweezers to break the adhesive.
3. Do not reuse removed leadless or chip components
since they are subject to stress fracture during
removal.
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.
How to replace Flat-IC
- Required tools -
1. Cut the pins of the defective IC with the wire cutter
pliers, and remove it completely away from the
board. If the IC is glued to the board, apply hot air to
complete the removal. CAUTION- Do not pull or
twist the pliers, it may damage the soldering pads in
the board .
2. Using the soldering Iron and the long nose pliers,
remove the IC pins that are still attached to the
board.
3. Using the de-solder braid and the soldering Iron,
remove the solder from the board soldering pads.
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.
5. Solder all pins to the soldering pads using a fine
tipped soldering iron.
6. Check with a magnifier for solder bridge between
the pins or for dry joint between pins and soldering
pads. To remove a solder bridge, use a de-solder
braid as shown in the figure below.
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.
