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.

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
50additional 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 translates 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.

Precautions
1. Precautions
Follow these safety, servicing and ESD precautions to prevent damage and protect against potential hazards such as electrical shock and X-rays.
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.

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.

Precautions
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.

Precautions
1-2 Servicing Precautions
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.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
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.
