2. PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in the appliance
have special safety related characteristics. These are
often not evident from visual inspection nor the
protection afforded by them necessarily can be obtained
by using replacement components rated for voltage,
wattage, etc. Replacement parts which have these
special safety characteristics are identified in this
Service Manual.
Electrical components having such features are
identified by marking with a
on the parts list in this Service Manual.
The use of a substitute replacement component which
does not have the same safety characteristics as the
PIONEER recommended replacement one, shown in the
parts list in this Service Manual, may create shock, fire,
or other hazards.
Product Safety is continuously under review and new
instructions are issued from time to time. For the latest
information, always consult the current PIONEER

2. When all components of test board D (LED) and all components of test board K (Sens) are malfunctioning.
The detailed list indicates “ALL” and not data for each Point.
Note:
“ALL” may indicate a malfunction that is not caused by the specific board.
Control signal lines from the test board A (LED) and optical signals lines
to the test board A (LED) are relayed via other boards so a malfunction
could be caused by defective connectors on boards in this chain.
3. When some components of test board A (LED) and all test board H (Sens) components are malfunctioning “Check” is
indicated when some components are malfunctioning.
The test address number and assessment for all related LED and Sens appear in the detailed list.

Note:
Execute a self-test only in Normal mode. Correct test results may not be obtained in Low Scan Lock mode or Super Low Scan Lock mode.
See the "DIP SW Information" display to check that the second and fourth switches from the left are set to 0. The "DIP SW Information"
display shows the status of the DIP switches on the LED-A assy.
If a change of the settings is required, first disconnect the USB connector between the Handwriting System and the plasma display, because
resetting of the Handwriting device is required, then change the settings. Then reconnect the Handwriting System to the plasma display.
If the Handwriting System is not connected to the plasma display, correct test results will not be obtained.
When the PC starts up or a USB cable is connected, the message
indicated on the right will appear.
The power indicator will flash alternately in green and orange.
As optical checking is being performed while the indicator is flashing,
do NOT touch the screen. Also do NOT touch the screen while a
self-test is being performed.

7.1.4 OPERATION CHECKS USING EXCHANGEABLE ASSY'S
As some Assy's become exchangeable by changing their jumper-pin settings, in some cases, operation checks of the Assy in
an area in failure are possible if you use an Assy in an area without problems.
• LED Assy's
On the LED-B and LED-C Assy's, the dedicated control lines for the LED-B and LED-C are determined by jumper-pin
settings (positions to which 0-ohm resistors are inserted).
By changing jumper-pin settings on these Assy's, you can use the LED-B Assy as the LED-C Assy, and vice versa.
Assy/JPJP1JP2JP3
LED-B?××
LED-C×?×
Note:?: With a 0-ohm resistor attached to the jumper pin, ×: Without a 0-ohm resistor attached
• With a resistor attached to JP1, the Assy is connected to the control line for HBOARD_SEL (1).
• With a resistor attached to JP2, the Assy is connected to the control line for HBOARD_SEL (2).
• Do NOT make a connection to JP3.
The following Assy's for the LEDs are dedicated, and they are not exchangeable by changing JP settings.
LED-A−−LED-D
LED-ELED-FLED-G
A
B
• SENSOR Assy's
On the SENSOR-I, SENSOR-J, and SENSOR-K Assy's, the sensor signal lines and the dedicated control lines for
SENSOR-I, SENSOR-J, and SENSOR-K are determined by jumper-pin settings (positions to which 0-ohm resistors are
inserted).
By changing jumper-pin settings on these Assy's, you can use the SENSOR-I, -J, and -K Assy's one in place of another.
It should be noted, however, that the SENSOR-K Assy needs a connector for servicing (Service Part No.: BZK1517)
attached, as the CN1 (40-pin) connector is not provided with this Assy.

SEN-I?×××
SEN-J×?××
SEN-K××?×
Note:?: With a 0-ohm resistor attached to the jumper pin, ×: Without a 0-ohm resistor attached
• With a resistor attached to JP1, the Assy is connected to the control line for HSDEC_SEL (1), and with a resistor
attached to JP5, the Assy is connected to the sensor-signal line for H_RCV (I).
• With a resistor attached to JP2, the Assy is connected to the control line for HSDEC_SEL (2), and with a resistor
attached to JP6, the Assy is connected to the sensor-signal line for H_RCV (J).
• With a resistor attached to JP3, the Assy is connected to the control line for HSDEC_SEL (3), and with a resistor
attached to JP7, the Assy is connected to the sensor-signal line for H_RCV (K).
• JP1 and JP5, JP2 and JP6, and JP3 and JP7 must be set in pairs.
• Do NOT make any connections to JP4 or JP8.
The following Assy's for the SENSORs are dedicated, and they are not exchangeable by changing JP settings.
