SAMSUNG PROJECTION TV SERVICE GUIDE

Section 1 - How to Use This Guide

How to use this Guide

This guide is divided into seven sections. Start with the section marked
“Instructions”.

The models covered in this document are derived from the P51A chassis. However; this
chassis has several different versions that are NOT covered in the service manuals.

Instructions to Start Service:

1. Obtain model, serial and symptom.

2. Review service bulletins (section 2), for common fixes. If Service Bulletin states that
repair is common, complete repair as indicated. Otherwise, proceed to section 3.

3. Review symptom/repair list as per the micro kit section (3). Order part number for
“kit” or individual parts.

Important Note: Order MACRO Kit only when technically required or the individual boards are

not available as an additional 45 minutes to 1 hour is needed for convergence, alignments and
other configuration setup.

4. If the previous steps do lead to a clear diagnosis, then proceed to the flow chart in
section 3 to help assist you in determining the correct PCB’s to order.

5. Place order through Samsung Parts Department.

Note: Distributors DO NOT carry PCB’s or macro kits, so backorder with
no eta will result. Parts Department will not accept an order for PTV parts without a
serial number because correct ID cannot be assured.

6. Parts will automatically ship 2nd day or faster. It is essential that the macro kit be
returned A.S.A.P. Your account will be charged, depending on the kit, up to
$1500.00 if the kit is not returned within 30 days.

7. When installing parts (refer to section 6 - Assembly/Disassembly), repair alignment
or adjustment will be necessary. There are three adjustment modes:
Convergence – to enter, press “Mute 183”
Geometric; Color Temp, etc. – to enter, press “Mute 182”

Geometric 1080i mode (DTV ready sets only, PCJ534RF, PCJ532RF, PCK5315R,
PCJ614RF, PCJ611RF, PCK6115R, HCJ552W/HCJ652W) - Refer to Service Bulletin
Follow detailed Alignment/Adjustment instructions in the service manual or the macro kit
instruction sheets.

SAMSUNG PROJECTION TV SERVICE GUIDE

Section 1 - How to Use This Guide

Important Points:

1. Most adjustments can be made using the remote control. However, in certain cases,

a “special remote” is required. This remote is included with each macro kit except the
PCJ522R series (not required). If you need this special remote you can order it from
Parts Department. (refer to section 2, service bulletin)

2. Option Byte: The firmware controlling the microprocessor may need to be changed

after Main PCB or Macro Kit is replaced. This is done by setting the option bytes.
Improper setting can cause symptoms including improper audio operation, menu
selections, or mechanical operations of the control panel door. Refer to the service
bulletin for correct settings.

3. The DTV input will not be recognized unless a DTV signal is applied to the

component input before DTV mode is selected.

4. Macro Kits are universal, PCB’s are not. A macro kit can be used for any version

replacement within the same model group. However; all macro kits are the newest
version, which may require the connectors be modified to ensure compatibility with the
CRT PCB connectors (refer to section 3).

5. Screen Replacement: Samsung PTV utilizes 2 screens; an outer Sunscreen and an

inner Tint Screen (Fresnel & Lenticular) sandwiched together. FYI, some models do not
have a Sun Screen. To order either of these screens under warranty, contact
Product/Technical Support for authorization. Note the name of the individual authorizing
the replacement for future reference, if needed.

6. CRT Burns: Permanent “burn ins” can occur if the set is used in any mode where

the screen is always dark or a screen image is static. This requires replacement of all
three CRT’s. Contact your RSE on how to handle this service. This is normally not
covered by warranty, so special approval must be granted.

7. Auto Mileage: We will pay $0.50 per mile travel time without special approval, up to

50 additional miles beyond the 25 miles required by contract. However; you must
provide proof, such as Internet driving directions or similar verifiable map and attach it to
the claim when submitted.

8. Macro Kits are always version 1 chassis. This means if an older version unit

previously had a Macro kit installed, parts ID via the serial number will be invalid.
Chassis version can be identified by the color of the connectors. White = original
version, black = version 1.

9. Returned parts: All parts must be returned with a description of the defect attached.

Failure to do so will result in delay in processing and credit. Also, include one copy of
the NARDA so warranty status can be confirmed.

Section 5 - Parts Data

How to get the correct parts the first time!

The parts table in section 5 is based on the production date (DOM=Date of Manufacture). This
must be determined before referencing parts data. DOM can be determined through the 4th
and 5th digit of the serial number by using the illustration provided (section 5). From there, you
can select the correct parts table according to the month/year bars.

Example:
Part needed; Main PCB for Model HCJ552W. Serial Number 3CEN700912X.

Step 1 – Locate table for HCJ552W in section 5.
Step 2 – Reference 4th and 5th digit of serial # = “N 7” which transl ates to July 2000.
Step 3 – Look up Main PCB under appropriate month/year, part number is AA94-02600B.

Parts Assembly Levels

There are three parts assembly levels:

1. Micro Kit – a small collection of component level parts along with a symptom/repair listing.
Locate the micro kit part number in section 3.

2. PCB Level – individual major PCB’s which comprise the bulk of the functional chassis.
Locate individual PCB part numbers in section 5.

3. Macro Kit – the major PCB’s pre-mounted and connected on the chassis rail is supplied as
a single unit. Locate macro kit part number in section 5.

1. Precautions

1-1 Safety Precautions

1. Be sure that all of the built-in protective
devices are replaced. Restore any missing
protective shields.

2. When reinstalling the chassis and its
assemblies, be sure to restore all protective
devices, including: nonmetallic control knobs
and compartment covers.

3. Make sure that there are no cabinet openings
through which peopleÑparticularly
childrenÑmight insert fingers and contact
dangerous voltages. Such openings include
the spacing between the picture tube and the
cabinet mask, excessively wide cabinet

ventilation slots, and improperly fitted back

covers.

If the measured resistance is less than 1.0
megohm or greater than 5.2 megohms, an
abnormality exists that must be corrected
before the unit is returned to the customer.

4. Leakage Current Hot Check (Figure 1-1):
Warning: Do not use an isolation
transformer during this test. Use a leakage­current tester or a metering system that
complies with American National Standards
Institute (ANIS C101.1, Leakage Current for
Appliances), and Underwriters Laboratories
(UL Publication UL1410, 59.7).

5. With the unit completely reassembled, plug
the AC line cord directly into the power
outlet. With the unitÕs AC switch first in the
ON position and then OFF, measure the
current between a known earth ground (metal
water pipe, conduit, etc.) and all exposed
metal parts, including: antennas, handle
brackets, metal cabinets, screwheads and
control shafts. The current measured should
not exceed 0.5 milliamp. Reverse the power­plug prongs in the AC outlet and repeat the
test.

Fig. 1-1 AC Leakage Test

6. Antenna Cold Check:
With the unitÕs AC plug disconnected from the
AC source, connect an electrical jumper across
the two AC prongs. Connect one lead of the
ohmmeter to an AC prong. Connect the other
lead to the coaxial connector.

7. X-ray Limits:
The picture tube is especially designed to pro­hibit X-ray emissions. To ensure continued
X-ray protection, replace the picture tube only
with one that is the same type as the original.
Carefully reinstall the picture tube shields and
mounting hardware; these also provide X-ray
protection.

8. High Voltage Limits:
High voltage must be measured each time ser­vicing is done on the B+, horizontal deflection
or high voltage circuits. Correct operation of
the X-ray protection circuits must be
reconfirmed whenever they are serviced.

(X-ray protection circuits also may be called

Òhorizontal disableÓ or Òhold-downÓ.)

Heed the high voltage limits. These include
the XÐray Protection Specifications Label, and
the Product Safety and X-ray Warning Note on
the service data schematic.

1-1 Safety Precautions (Continued)

9. High voltage is maintained within specified
limits by close-tolerance, safety-related
components and adjustments. If the high
voltage exceeds the specified limits, check
each of the special components.

10. Design Alteration Warning:
Never alter or add to the mechanical or
electrical design of this unit. Example: Do not
add auxiliary audio or video connectors. Such
alterations might create a safety hazard. Also,
any design changes or additions will void the
manufacturerÕs warranty.

11. Hot Chassis Warning:
Some TV receiver chassis are electrically
connected directly to one conductor of the AC
power cord. If an isolation transformer is not
used, these units may be safely serviced only
if the AC power plug is inserted so that the
chassis is connected to the ground side of the
AC source.

To confirm that the AC power plug is inserted
correctly, do the following: Using an AC
voltmeter, measure the voltage between the
chassis and a known earth ground. If the
reading is greater than 1.0V, remove the AC
power plug, reverse its polarity and reinsert.
Re-measure the voltage between the chassis
and ground.

12. Some TV chassis are designed to operate with
85 volts AC between chassis and ground,
regardless of the AC plug polarity. These units
can be safely serviced only if an isolation
transformer inserted between the receiver and
the power source.

13. Some TV chassis have a secondary ground
system in addition to the main chassis ground.
This secondary ground system is not
isolated from the AC power line. The two
ground systems are electrically separated by
insulating material that must not be defeated
or altered.

14. Components, parts and wiring that appear to
have overheated or that are otherwise
damaged should be replaced with parts that
meet the original specifications. Always
determine the cause of damage or overheat­ing, and correct any potential hazards.

15. Observe the original lead dress, especially
near the following areas: Antenna wiring,
sharp edges, and especially the AC and high
voltage power supplies. Always inspect for
pinched, out-of-place, or frayed wiring. Do
not change the spacing between components
and the printed circuit board. Check the AC
power cord for damage. Make sure that leads
and components do not touch thermally hot
parts.

16. Picture Tube Implosion Warning:
The picture tube in this receiver employs
Òintegral implosionÓ protection. To ensure
continued implosion protection, make sure
that the replacement picture tube is the same
as the original.

17. Do not remove, install or handle the picture
tube without first putting on shatterproof
goggles equipped with side shields. Never
handle the picture tube by its neck. Some
Òin-lineÓ picture tubes are equipped with a
permanently attached deflection yoke; do not
try to remove such Òpermanently attachedÓ
yokes from the picture tube.

18. Product Safety Notice:
Some electrical and mechanical parts have
special safety-related characteristics which
might not be obvious from visual inspection.
These safety features and the protection they
give might be lost if the replacement compo­nent differs from the originalÑeven if the
replacement is rated for higher voltage,
wattage, etc.

Components that are critical for safety are
indicated in the circuit diagram by shading,
( ) or ( ).

Use replacement components that have the
same ratings, especially for flame resistance
and dielectric strength specifications.
A replacement part that does not have the
same safety characteristics as the original
might create shock, fire or other hazards.

1-2 Servicing Precautions

1. Servicing precautions are printed on the
cabinet. Follow them.

2. Always unplug the unitÕs AC power cord from
the AC power source before attempting to: (a)
Remove or reinstall any component or
assembly, (b) Disconnect an electrical plug or
connector, (c) Connect a test component in
parallel with an electrolytic capacitor.

3. Some components are raised above the printed
circuit board for safety. An insulation tube or
tape is sometimes used. The internal wiring is
sometimes clamped to prevent contact with
thermally hot components. Reinstall all such
elements to their original position.

4. After servicing, always check that the screws,
components and wiring have been correctly
reinstalled. Make sure that the portion around
the serviced part has not been damaged.

5. Check the insulation between the blades of the
AC plug and accessible conductive parts
(examples: metal panels, input terminals and
earphone jacks).

6. Insulation Checking Procedure: Disconnect the
power cord from the AC source and turn the
power switch ON. Connect an insulation
resistance meter (500V) to the blades of the AC
plug.

The insulation resistance between each blade
of the AC plug and accessible conductive parts
(see above) should be greater than 1 megohm.

7. Never defeat any of the B+ voltage interlocks.
Do not apply AC power to the unit (or any of
its assemblies) unless all solid-state heat sinks
are correctly installed.

8. Always connect a test instrumentÕs ground
lead to the instrument chassis ground before
connecting the positive lead; always remove
the instrumentÕs ground lead last.

9. When some parts inside the optical engine
(except lamp) are damaged, replace the whole
optical engine.

Precautions

Samsung Electronics 1-3

Warning 1 : First read the “Safety Precautions” section of this manual. If some unforeseen circumstance creates a

conflict between the servicing and safety precautions, always follow the safety precautions.

Warning 2 : An electrolytic capacitor installed with the wrong polarity might explode.

1-3 Precautions for Electrostatically Sensitive Devices (ESDs)

1. Some semiconductor (Òsolid stateÓ) devices
are easily damaged by static electricity. Such
components are called Electrostatically
Sensitive Devices (ESDs); examples include
integrated circuits and some field-effect
transistors. The following techniques will
reduce the occurrence of component damage
caused by static electricity.

2. Immediately before handling any semicon
ductor components or assemblies, drain the
electrostatic charge from your body by
touching a known earth ground. Alternatively,
wear a discharging wrist-strap device. (Be
sure to remove it prior to applying powerÑ
this is an electric shock precaution.)

3. After removing an ESD-equipped assembly,
place it on a conductive surface such as
aluminum foil to prevent accumulation of
electrostatic charge.

4. Do not use freon-propelled chemicals. These
can generate electrical charges that damage
ESDs.

5. Use only a grounded-tip soldering iron when
soldering or unsoldering ESDs.

6. Use only an anti-static solder removal device.
Many solder removal devices are not rated as
Òanti-staticÓ; these can accumulate sufficient
electrical charge to damage ESDs.

7. Do not remove a replacement ESD from its
protective package until you are ready to
install it. Most replacement ESDs are
packaged with leads that are electrically
shorted together by conductive foam,
aluminum foil or other conductive materials.

8. Immediately before removing the protective
material from the leads of a replacement ESD,
touch the protective material to the chassis or
circuit assembly into which the device will be
installed.

9. Minimize body motions when handling
unpackaged replacement ESDs. Motions such
as brushing clothes together, or lifting a foot
from a carpeted floor can generate enough
static electricity to damage an ESD.
