1. BASIC ITEMS FOR SERVICE
1.1 QUICK REFERENCE
Notes when visiting for service
1. Notes when disassembling/reassembling
1 Rear case
When reassembling the rear case, the screws must be tightened in a
specific order. Be careful not to tighten them in the wrong order forcibly.
For details, see "Rear Case" in "5. DISASSEMBLY".
2 Attaching screws for the HDMI and system cable terminals
When attaching the HDMI and system cable terminals after
replacing the Assembly, secure the terminals manually with a
screwdriver, but not with an electric screwdriver.
If you tighten the screws too tightly with an electric screwdriver, the
screw heads may be damaged, in which case the screws cannot
be untightened/tightened any more.
2. On parts replacement
1 How to discharge before replacing the Assys
A charge of significant voltage remains in the Plasma Panel even
after the power is turned off. Safely discharge the panel before
replacement of parts, in either manner indicated below:
A: Let the panel sit at least for 3 minutes after the power is turned off.
B: Turn the Large Signal System off before the power is turned off
then, after 1 minute, turn the power off.
For details, see "5.6 [1] PANEL DRIVE-POWER ON/OFF
FUNCTION".
2 On the settings after replacement of the Assys
Some boards need settings made after replacement of the Assys.
For details, see "8. EACH SETTING AND ADJUSTMENT".
3. On various settings
1 Setting in Factory mode
After a Mask indication into the panel is performed, be sure to
set the Mask setting to "OFF" then exit Factory mode.
Adjustments and Settings after replacement of the
Assys (Procedures in Factory mode)

count and maximum temperature value
1 Select {PANEL FACTORY}, {ETC}, then {P COUNT INFO}. (After entering Factory
mode, press [MUTING] once, press [ENTER/SET], press [
j] seven times, press
[ENTER/SET], then press [
j] six times.)
2 Press [l] to select "CLEAR". Hold [ENTER/SET] pressed for at least 5 seconds.
After clearance is completed, "ETC" is automatically selected. Clear the maximum
temperature value (MAX TEMP) in the same manner.
4. Other Assys (Panel): Clearance of the maximum temperature value
1 Select {PANEL FACTORY}, {ETC}, then {MAX TEMP}. (After entering Factory mode,
press [MUTING] once, press [ENTER], press [
j] seven times, press [ENTER/SET],
then press [
j] seven times.)

Select {INFORMATION} then {HOUR METER}.
(After entering Factory mode, press [
j] four times.)
2. Confirmation of the Power-down and Shutdown histories
1 Panel system
PD: Select {PANEL FACTORY} then {POWER DOWN}.
(After entering Factory mode, press [MUTING] once, press [ENTER/SET],
then press [
j] two times.)
SD: Select {PANEL FACTORY} then {SHUT DOWN}.
(After entering Factory mode, press [MUTING] once, press [ENTER/SET],
then press [
j] three times.)
2 MR section
Select {INFORMATION} then {MAIN NG}.
(After entering Factory mode, press [
j] three times.)
3 Panel main section
Select {PANEL MAIN FACTORY} then {PM NG INFO}.
After entering Factory mode, press [MUTING] twice, then press [ENTER/SET].
3. How to display the Mask indication
1 Mask indication in the panel side
1. Select {PANEL FACTORY} then {RASTER MASK SETUP}.
(After entering Factory mode, press [MUTING] once, press [ENTER/SET],
then press [
j] 8 times.)
2. Press [ENTER/SET], then select a Mask indication, using [
