Schematic Diagram
Samsung Electronics7-1
7. Schematic Diagram
7-1 Circuit Description
■ SMPS Board
The SMPS used for the PDP has been designed to be efficient, compact and lightweight. For VS and VA outputs, a LLC converter
has been used. For the other outputs, a Flyback converter has been used.
■ LOGIC Board
The logic circuit consists of a Logic Main Board and an Address Buffer Board. The Logic Main Board decodes the video signal
encoded by the Video Board, outputs the ADDRESS data signal for each pattern and generates X and Y drive signals. The
Address Buffer Board buffers and transfers the ADDRESS data output signal using TCP IC.
- LVDS with built-in video signal processing (W/L, error diffusion, APC, FCR, etc.) applied and 1 ASIC chip.
- Outputs the address Drive IC control and data signals to the Buffer Board.
- Outputs the control signal for the X and Y Drive Boards.
- Monitors major drive voltages (Micom Circuit Block); detects if a surge voltage has been applied and protects the Drive Circuit.
- Temperature Adaptive Operating Mode (Low Temperature/Room Temperature/High Temperature); Discharge optimization for
each temperature level.
■ X-MAIN Board
Connects to the X terminal block, 1) provides maintaining voltage waveform (including ERC), and 2) maintains the Ve bias in the
Scan section.
■ Y-MAIN Board
Connects to the Y terminal block, 1) provides maintaining voltage waveform (including ERC), 2) provides Y Rising, Falling Ramp
waveforms, and 3) maintains the Vscan bias.
■ Address Buffer Board
It delivers the data signal and control signal to the TCP.
1. Make sure all protective devices are properly installed
including non-metallic handles and compartment covers
when installing or re-installing the chassis or chassis
assemblies.
2. Make sure that no gaps exist between the cabinets for
children to insert their fingers in to prevent children from
receiving electric shocks. Gaps mentioned above include
ventilation holes between the PDP module and the cabinet mask, and the improper installation of the rear cabinet.
Errors may occur when the resistance is below 1.0 ㏁ or
over 5.2 ㏁.
In these cases, make sure that the device is repaired
before sending it back to the customer.
3. Check for Electricity Leakage (Figure 1-1)
Warning: Do not use an insulated transformer for checking the leakage. Use only those current leakage testers
or mirroring systems that comply with ANSIC 101.1 and
the Underwriter Laboratory's specifications (UL1410,
59.7).
Fig. 1-1 AC Leakage Test
4. A high voltage is maintained within the specified limits
using safety parts, calibration and tolerances. When
voltage exceeds the specified limits, check each special
part.
5. Warning for Engineering Changes:
Never make any changes or additions to the circuit
design or the internal part for this product.
Ex: Do not add any audio or video accessory
connectors. This might cause physical damage.
Furthermore, any changes or additions to the original
design/engineering will invalidate the warranty.
6. Warning - Hot Chassis:
Some TV chassis are directly connected to one end of
the AC power cord for electrical reasons.
Without insulated transformers, the product can only be
repaired safely when the chassis is connected to the
earth end of the AC power source.
To make sure the AC power cord is properly connected,
follow the instructions below. Use the voltmeter to
measure the voltage between the chassis and the
earth ground. If the measurement is over 1.0V, unplug
the AC power cord and change the polarity before reinserting it. Measure the voltage between the chassis
and the ground again.
7. Some TV chassis are shipped with an additional secondary grounding system. The secondary system is
adjacent to the AC power line. These two grounding
systems are separated in the circuit using an unbreakable/unchangeable insulation material.
8. When any parts, material or wiring appear overheated or
damaged, replace them with new immediately. When
any damage or overheating is detected, correct this
immediately and make a regular check of possible
errors.
9. Check for the original shape of the lead, especially that
of the antenna wiring, any sharp edges, the AC power
and the high voltage power. Carefully check if the wiring
is too tight, incorrectly placed or loose. Never change the
space between the part and the printed circuit board.
Check the AC power cord for possible damages. Keep
the part or the lead away from any heat-emitting
materials.

10. Safety Indication:
Some electrical circuits or device related materials
require special attention to their safety features, which
cannot be viewed by the naked eye. If an original part is
replaced with another irregular one, the safety or
protective features will be lost even if the new one has a
higher voltage or more watts.
Critical safety parts should be bracketed with ( ).
Use only regular parts for replacements (in particular,
flame resistance and dielectric strength specifications).
Irregular parts or materials may cause electric shock or
fire.

1. The service instructions are printed on the cabinet, and
should be followed by any service personnel.
2. Make sure to unplug the AC power cord from the power
source before starting any repairs.
(a) Remove or re-install parts or assemblies.
(b) Disconnect the electric plug or connector, if any.
(c) Connect the test part in parallel with the electrolytic
capacitor.
3. Some parts are placed at a higher position than the
printed board. Insulated tubes or tapes are used for this
purpose. The internal wiring is clamped using buckles to
avoid contact with heat emitting parts. These parts are
installed back to their original position.
4. After the repair, make sure to check if the screws, parts
or cables are properly installed. Make sure no damage is
caused to the repaired part and its surroundings.
5. Check for insulation between the blade of the AC plug
and that of any conductive materials (i.e. the metal
panel, input terminal, earphone jack, etc).
6.Insulation Check Process: Unplug the power cord from
the AC source and turn the switch on. Connect the insulating resistance meter (500v) to the AC plug blade.
The insulating resistance between the blade of the AC
plug and that of the conductive material should be more
than 1 ㏁.
7. Any B+ interlock should not be damaged.
If the metal heat sink is not properly installed, no
connection to the AC power should be made.
8. Make sure the grounding lead of the tester is connected
to the chassis ground before connecting to the positive
lead. The ground lead of the tester should be removed
last.
9. Beware of risks of any current leakage coming into
contact with the high-capacity capacitor.
10. The sharp edges of the metal material may cause
physical damage, so protect yourself by wearing gloves
during the repair.
11. Due to the nature of plasma display panels, partial afterimages may appear if a still picture is displayed on the
screen for a long period of time.
This is caused by brightness deterioration due to the
storage effect of the panel, and to prevent this from
happening, we recommend that the brightness and contrast are reduced.
(e.g.) Contrast: 25, Brightness: 50

Warning 1: First carefully read the "Safety Instruction" in this service manual.
When there is a conflict between the service and the safety instructions, follow the safety instruction at all times.
Warning 2: Any electrolytic capacitor with the wrong polarity will explode.
1-2 Servicing Precautions
Page 39
1-3 Static Electricity Precautions
1. Some semi-conductive ("solid state") devices are
vulnerable to static electricity. These devices are known
as ESD. ESD includes the integrated circuit and the field
effect transistor. To avoid any materials damage from
electrostatic shock, follow the instructions described
below.
2. Remove any static electricity from your body by
connecting the earth ground before handling any
semi-conductive parts or assemblies. Alternatively,
wear a dischargeable wrist-belt.
(Make sure to remove any static electricity before
connecting the power source - this is a safety instruction
for avoiding electric shock)
3. Remove the ESD assembly and place it on a conductive
surface such as aluminum foil to prevent accumulating
static electricity.
4. Do not use any Freon-based chemicals.
Such chemicals will generate static electricity that
causes damage to the ESD.
5. Use only grounded-tip irons for soldering purposes.
6. Use only anti-static solder removal devices.
Most solder removal devices do not support an
anti-static feature. Asolder removal device without an
anti-static feature can store enough static electricity to
cause damage to the ESD.
7. Do not remove the ESD from the protective box until the
replacement is ready. Most ESD replacements are
covered with lead, which will cause a short to the entire
unit due to the conductive foam, aluminum foil or other
conductive materials.
8. Remove the protective material from the ESD
replacement lead immediately after connecting it to the
chassis or circuit assembly.
9. Take extreme caution in handling any uncovered ESD
replacements. Actions such as brushing clothes or lifting
your leg from the carpet floor can generate enough static
electricity to damage the ESD.
Precaution

CAUTION
These servicing instructions are for use by
qualified service personnel only.
To reduce the risk of electric shock do not
perform any servicing other than that contained in the
operating instructions unless you are qualified to do so.

1) Definition of a Logic Circuit
ALogic Circuit consists of a Logic Main Board, which decodes the video signal encoded on the Video Board, outputs the address
data signal, and generates and outputs the X, Y drive signals, and an Address Buffer Board which buffers and outputs the address
data output signal to the TCP IC.
2) Waveform for Normal Operations
When the PDP and the Logic Board are normal, the Operating LED blinks at a half second interval. In this case, the V-SYNC and
data signals are output normally.
In case of problems with the product, please refer to the troubleshooting procedures described below.
① Visual Inspection: Check if the Operating LED on the Logic Main blinks at a half second interval.
▶ If the frequency of the blinking is too fast or slow, it means that the MICOM has failed to process the data properly.
Therefore, you have to reload the data onto the MICOM. Load the data using GA-WRITER when the power is
connected to the module.
② If no problem is found during the Visual Inspection, check if the drive waveform and the address data outputs are normal using
an oscilloscope. (Checkpoint: The DAMPING R-NET part output of each data output terminal.)
▶ If no drive waveform or address output is measured, this means that there is a drive problem due to MICOM data corruption,
which was the reason in the Visual Inspection. Therefore, in this case, reload the data as you did in the Visual Inspection.
▶ When data output is measured but it is abnormal, and the drive waveform is abnormal, it is probably due to a short-circuit of
the hardware. If the address data is abnormal, the screen may be abnormal due to abnormal data output by an abnormal
operation of the DDR memory due to an abnormal Vref voltage, or the screen may be abnormal due to a short-circuit in the
ass'y inside the board. You have to conduct a short-circuit test for each case.
▶ If the Vref voltage (the voltage of the Voltage Divider) is lower than 1.25V, check the resistance of the resistance output part
and check if the circuit is normal. If the Vref voltage is normal, the screen operates normally.
▶ If the screen is abnormal, even though the Vref voltage is normal, check if there is a short circuit by conducting a
short-circuit test. If a short-circuit is found, repair it. If the short-circuit is an internal one, replace the board.
▶The following waveforms represent normal V-sync and address data output waveforms.
