1. Introduction

1-1. PDP Unit (FPF42C10660UD) Analysis Manual

This manual explains the failure analysis procedure l for PDP unit and it is applied to analysis by
the test equipment below. To perform failure analysis, see the data, as follows :

. Repair flow

. Check point (X-SUS) ............................ 3-1.

. Check point (Y-COM) .......................... 3-2.

. Check point (DC/DC) ........................... 3-3.

. Voltage check........................................ 3-4.

. Glossary ................................................ 3-5.

. Connection to test equipment ................ 3-6.

. Test equipment....................................... 3-7.

. Photo (Burn-in unit) .............................. 3-8.

. Burn-in unit Instruction Manual ........... 3-9.

. Criteria table.......................................... 3-10.

. Voltage setting procedure ..................... 3-11.

. Display test Manual .............................. 3-12.

. PC board replacing procedure............... 3-16.

Always, allow the self electrical discharge about 30 seconds between shutting down the external power
supply and the operation of replacing each PC board or disconnecting connectors in the repair and
analysis process.

1-2. Test Equipment (3-6, 7)

Display test is conducted with the facilities listed below and whether the test results can satisfy the criteria
is determined by the display special point standard in the 3-11.

<Facilities used>

1. Video signal generator : Astro design VG-826 (Refer to the 3-12)

2. External keyboard : Astro design RB-614C (Refer to the 3-12)

3. PDP function test switch (APC/DISP ENABLE/HQEN/luminance variable volume)

1 APC (monitoring power consumption/abnormal operation)

ON: NEW.APC mode [Stability hour (about 3 minutes)]

It can monitor the power consumption on the circuit to maintain the rating power.
In addition, it can monitor the X/YSUS operation and shut down the PDP circuit immediately
when any abnormal operation is detected. This prevents further damage to the circuit.

OFF: OLD.APC mode [Stability hour (about 10 seconds)]

In this mode, the internal power supply is activated forcibly to run the electricity
on the circuit, regardless of whether abnormal operation is detected.
Set this mode with care for failure analysis.

The use of APC switch in “OFF” mode may likely cause a secondary failure. Thus, handle this switch
with care. Do not power on the external power supplies at one time.

2 DISP ENABLE (screen display ON/OFF)

ON : Every operation of displaying data is disabled.
OFF : Every operation of displaying data is enabled.

3 HQEN ENABLE (false frame line deletion function)

ON : The difference of each step is lightened in gradation display
OFF : Each step in gradation is displayed as it is and false frame line can be seen.

4 Luminance variable volume (for changing the screen luminance)

Turn the volume to the right to increase the brightness or turn the volume to the left to decrease
the brightness.

4. External power supplies (See the 3-7)

1 Vcc 0 ~ 6 V 10 A
2 Va 0 ~ 110 V 2.0 A
3 Vs 0 ~ 250 V 15 A

* Observe the following sequence, as shown below when using external power supplies:
Power ON : Vcc → Va → Vs
Power OFF : Vs → Va → Vcc

Oscilloscope : A device that allows the flow and strength of the running current to be visually

checked and measured.
Gradation : Shading of the display color.
External power ON : Running the external powers (Vcc. Va. Vs) on the designated voltage, unless

otherwise specified.
External power OFF : Making the external powers (Vcc. Va. Vs) to stop their operation completely,

unless otherwise specified.
White solid : A condition when the screen display is entirely white.
Tapping : Light impact.
Panel : The indication part of the plasma display panel (PDP).
Parts : Each PC board and parts mounted in the PC boards.
Panel voltage : The voltage required to operate the PDP normally.
Burn-in rack : Test equipment of the shelf test in which the PDP unit is left to stand in drive

condition.
Flexible cable : The cable for connecting the electric circuit to the panel.
Flicker : Continuous switching between bright and dark views by the PDP itself.
Protection cover : A cover made by aluminum to protect the PDP entirely during test.
Probe : A cable with contact finger that can transfer the status of the electric circuit to be

measured to an oscilloscope.
Remote control box : The device that can control the power on/off state of the power supply for

exclusive use (FPF10P-AC100/240B).
Unit of COM : The unit of circuits connected to the panel with flexible cable.

(YCOM UP/DOWN, XBUS UP/DOWN, address sections, the unit of PC boards

in ACOM1 to 5)
CPU : The unit for controlling the circuit operation.
DOYSU : Used in the drive voltage in the Y direction.

SUS : XSUS or YSUS.
Vcc : The power supply at 5 V, which is used to operate the logic section mainly.
Va : The power supply at 60 V, which is used to write data on the panel.
Vs : The power supply ranging from 127 V to 180 V, which is used to maintain

display data. In addition, this can serve as the primary side for the secondary

voltage (Vw, _Vy, Vsc).
XSUS: The name of the circuit that controls the panel operation in the X direction.
YCOMDV: The name of the panel drives voltage signal output from YCOM UP/DOWN

section.
YCOM: The circuit used to output a panel Y line selection signal and the voltage of a

display data keep signal.

3-11. Voltage Setting Procedure

Vs and _Vy fluctuation, voltage margin is measured and a set voltage is decided. Use the external and
internal (DC/DC in 3-3) power supplies to generate +Vs and _Vy respectively.
Please see to Display Test Manual (3-12) for each display pattern.

1. Panel Voltage Measuring Procedure

Judgment of the minimum voltage : The level at which every point is turned on upon raising the voltage

slowly at each point (except the special points).

Special point : The point that is not turned on when every other point is turned on.

This point requires a higher voltage to be turned on.

Judgment of the maximum voltage : The level at which the surplus points are disappeared with a straight

change in voltage upon lowering the voltage slowly at each point.

Surplus point : The display point other than display data

(Except constant surplus point).

(Procedure) (Operation)
1 Preparation Install and turn on the test equipment in the white solid display in the

highest level for four minutes.

2 Vs(min) setting _Vy = _160 V (Temporary setting)

Setting : APC : ON, HQEN : OFF
Display : Gray-scale [R16 gradation : Left discernment-Right privily]

Cross-hatch + slash-pattern (G The highest gradation)

3 Vs Set value Decision [The set value of Vs is decided from Vs (min) in this paragraph.]

Vs (min)=Vs (min) +4 V
(1) For Vs (min)<180 V/Vs(Set value)=180 V
(2) At setting Vs = 180 V, Margin measurement in clause 4-7.

When abnormality is found in the display confirmation, VS is
assumed 170 V, and executes clause 4-7. But, it is assumed Vs
(min) <170 V.

4 _Vy Margin measurement [Set value as for Vs. _Vy margin is measured in this paragraph.]

Setting : APC : ON, HQEN : OFF
Display : _Vy (min) : Overall lighting

(1) _Vy (Set value) = _Vy _4 V

But, for a | _Vy (Set value) |<| _145 V|, _Vy(Set value) _145

(2) _Vy (Set value) _4V<_Vy (max)

6 Margin confirmation [The Vs margin is finally set by the result of the _Vy setting.]

Vs (min) is confirmed with Vs _3V.
Vs (max) is confirmed with Vs +4V.
