1. Safety Precautions
1. Safety Precautions
(1) When moving or laying down a PDP Set, at least two people must work together. Avoid
any impact towards the PDP Set.
(2) Do not leave a broken PDP Set on for a long time. To prevent any further damages, after
checking the condition of the broken Set, make sure to turn the power (AC) off.
(3) When opening the BACK COVER, you must turn off power (AC) to prevent any electric
shock. When PDP is operating, high voltage and high current inside the Set can cause
electric shocks.
(4) When loosening screws, check the position and type of the screw. Sort out the screws and
store them separately for reassembling. Because screws holding PCBs are working as
electric circuit GROUNDING, make sure to check if any screw is missing when
assembling/reassembling. Do not leave any screws inside the set.
(5) If you open the BACK COVER, you will see a
Panel Gas Exhaust Tube (Picture. 1-1) inside
the bracket. If this part is damaged, the entire
PDP PANEL must be replaced. Therefore,
when working with the set, be careful not to
damage this part.
Picture 1-1. Panel Gas Exhaust Tube
(6) A PDP Set contains different kinds of
connector cables. When connecting or disconnecting cables, check the direction and
position of the cable beforehand.
(7) Connect/disconnect the connectors slowly with care especially FFC (film) cables and FPC
cables. Do not connect or disconnect connectors instantaneously with force, and handle
them carefully for reassembling.
(8) Connectors are designed so that if the number of pins or the direction does not match,
connectors will not fit. When having problem in plugging the connectors, check their kind,
position, and direction.

Main PCB Trouble Diagnosis
8-2. POWER PCB Trouble Diagnosis
After checking High Voltage Board / Scan Relay Board / Data Relay Board (refer to II. PDP
MODULE), and the set still does not operate, then check if the following Power PCB's Trouble
Symptoms appear.
After unplugging Power Connectors of Power PCB (CN806 and CN805) and checking
remaining voltage, there still exist several tens of remaining voltage.
When output condition of Power PCB is set to low-voltage, output voltage table lists 3~7 are
NOT normal. Or when set to high-voltage, output voltage table list 1~2 are NOT normal. (Refer
to 4-3)
When output condition of Power PCB is set to low-voltage, output voltage table lists 3~7 are
normal. But when set to high-voltage, output voltage table list 1~2 are NOT normal. (Refer to
4-3)
After turning on the PDP set with Remote Controller when output condition of Power Module is
set to high-voltage, the LED turn "Green" but the "Power Shut Down" happens after 2~3
seconds.
If high voltage (Vsus, Vadd) measured from Power PCB is different from that of optimum
adjusting voltage label, re-adjust the voltages referring to "I. 6-2. POWER Adjustments"

9. TROUBLE DIAGNOSIS
[NOTE] Refer to "PDP MODULE" section for module diagnosis.
* Refer to Chapter II for Symptoms of other parts with exception of MAIN, SUB PCB and POWER
PCB Trouble.
9-1. Facts you must know when trouble diagnosing or repairing
(1) Trouble diagnosing and repairing of set mean find out which PCBs or blocks are not working and
replace them with new PCBs. Repairing the broken PCBs are not necessary. Keep the broken
PCBs and return them to service center or R&D center.
(2) This TROUBLE DIAGNOSIS list only contains representative and simple PCB trouble diagnosis
and Module Exchange method. Therefore, if you find Sets that are difficult to diagnose or to
repair, contact R&D center.
(3) Basic TROUBLE DIAGNOSIS procedure
Check problem Symptoms -> Open BACK COVER -> Trouble Diagnosis e Replace broken PCB
-> Adjust new PCB module -> HEATRUN (for at least 30 minutes, input TEST PATTERN FULL
WHITE), full FUNCTION test -> Repair Complete.
(4) Required equipments for trouble diagnosis
- DIGITAL MULTIMETER (User Mode : measure DC VOLTAGE, measure DIODE VOLTAGE,
SHORT-OPEN TEST )
- Screwdriver (or electric screwdriver), plastic adjusting tool
- Oscilloscope (for detailed examination only)
(5) Each BLOCK operations explained in this manual include OSCILLOSCOPE waveforms, but these
are for reference only and utilizing them to repair PCBs is not necessary.
(6) Before replacing PCBs, you MUST turn the AC Switch "OFF".
(7) After replacing High Voltage Board, POWER, and MAIN & SUB PCB, extra adjustment might be
needed. (Refer to I. 6. Adjusting Method)
(8) After the set is repaired, leave BACK COVER open for followings. Run HEATRUN for at least
30 minutes by displaying TEST PATTERN (FULL WHITE) of SERVICE MODE (Refer to
Service Manual I.5. Service Mode). Check the screen conditions and basic functions (remote
control operation etc.).
(9) After BACK COVER is closed, redo HEATRUN for at least one hour with FULL WHITE input
using TEST PATTERN of SERVICE MODE. Check the screen conditions and basic functions.
9-2. Typical Symptoms of PCB problem or bad Connection
(1) Symptoms of POWER PCB Trouble
Not even a weak discharge detected on the screen.
Discharge on the screen is unstable
Set is making unusual noise
POWER SHUT DOWN occur (refer to Service Manual I. 9-3)
-39-
TROUBLE DIAGNOSIS
(2) Symptoms of MAIN or SUB PCB Trouble
Only a weak discharge shows on the screen, but it is displaying No images.
Images are abnormal
Particular input signal (Video, PC or Component etc.) does not work.
No SOUND
Occasionally, set does not operate normally. Turning off and on the AC power make
the set to operate normal again.
Remote Control or KEY does not work.
POWER SHUT DOWN occur (refer to Service Manual I. 9-3 )
(3) Representative Symptoms caused by bad Connection between PCBs.
[Note] Dust or extraneous materials may cause bad connections. Most of the time, applying soft
brush, AIR FRESHER, or breath to clean dust or extraneous materials can solve it. And
then reassemble the Connector.
9-3. Trouble Diagnosis and Repairing Method for Representative Symptoms
(1) When POWER SHUT DOWN occurs
<1> Definition of "SHUT DOWN"
- While LED color is green, POWER PCB does not make any operating noise. (Red: STAND
BY, Green: Operating)
- When the set is turned on power relay does not operate normally, and POWER PCB does not
make any operating noise.
<2> Trouble Repairing Procedure
- As shown in Fig. 5, first check whether "LOW VOLTAGE" part or "HIGH VOLTAGE" part has
problems.
- If "LOW VOLTAGE" part's problem is detected, diagnose and repair the SET as shown in Fig. 6.
- If "HIGH VOLTAGE" part's problem is detected, diagnose and repair the SET as shown in Fig. 6.
- When disconnecting/connecting connectors, you MUST turn "OFF" the AC power
and check the direction and position of the connectors before working.
- Whenever you reassemble connectors connecting High Voltage Board and
POWER PCB(CN805, CN806), remaining voltage still exists in the POWER PCB
could cause electric shock and damage the set. Therefore always reassemble the
connectors several minutes after AC power is off. To be more careful, using a
MULTIMETER you should check to see if Vsus is less than 10V and then connect
connectors.
-40-
TROUBLE DIAGNOSIS
(2) When weak Discharge exists on screen but "OSD screen" can not be seen
<1> Definition of this symptom
- When the set is turned on, screen is BLACK but Weak Discharge (luminescence) exists.
- OSD does not show on screen and the set does not respond to remote controller or KEY panel
buttons.
<2> PCB CHECK PRIORITY
- MAIN PCB, SUS PCB
<3> Repairing Procedure
- Check LVDS cable (MAIN PCB to DIGITAL PCB) first and then other connectors connecting
MAIN PCB. If this does not fix the problem replace MAIN PCB.
