ServiceManual

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

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 within 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.

decoder.

1. Set same settings as NTSC adjustment

2. Apply a 1080i signal, and repeat adjustments as

from step 2 in NTSC adjustment.

3. If pattern is not available, use a color signal in

1080i and adapt the adjustment to that available

signal.

-47- Service Manual

Service mode (electronic controls, continued)

Red, green & blue screen cutoff

1. Use either a no input signal condition or raster from

the NTSC generator.

2. Observingthegreentubedirectlyorviaareflective

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.

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. In picture menu set PICTURE NORM to YES.

2. Apply color bars to the video input.

3. Magenta is composed of two colors, blue and red.

4. 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.

Color check

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.

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

showninfigure64.

2. Connect an RF signal generator to the RF

antenna input.

Procedure:

1. Apply the following signal from the RF signal

generator:

Video: 100 IRE flat field, 30% modulation.

Audio: 300Hz, 100% modulation, monaural

(70 ± 5dB, 75Ωopen, P/S 10dB). Make sure to turn

off 75µs pre-emphasis.

2. Adjust DAC “MTSIN”

MTS-INPUT

data until the

voltage measured is 106mV ± 6.0mV RMS.

Stereo separation adjustment

(SEPAL & SEPAH)

Preparation:

1. Connect an RF signal generator to the RF

antenna input.

2. Connect an oscilloscope probe to TPA7 (R_out).

Procedure:

1. Set PTV to Stereo Mode (in the audio menu).

2. Apply the following signal from the RF signal

generator:

Video: 100 IRE flat field, 30% modulation.

Audio: 300Hz, 30% modulation, stereo (left only)

(70dB ± 5dB, 75ΩOPEN, P/S 10dB).

Note: Set the 30% modulation with the pilot

light SW and N.R. switches OFF then turn

them ON while testing.

3. Adjust MTS low-level separation “SEPAL” DAC

data (in the service menu) until the amplitude of the

measured waveform on the scope is minimum.

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:

Note: Pin 10 measurement will not change

regardless of the value stored in CLOCK.
