1. CONTRAST OF MISCELLANEOUS PARTS

NOTES:

A

Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List.
The mark found on some component parts indicates the importance of the safety factor of the part.
Therefore, when replacing, be sure to use parts of identical designation.
Screws adjacent to mark on product are used for disassembly.
For the applying amount of lubricants or glue, follow the instructions in this manual.
(In the case of no amount instructions, apply as you think it appropriate.)
Nos. indicate the pages and Nos. in the service manual for the base model.
When ordering resistors, first convert resistance values into code form as shown in the following examples.
Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%,
and K=10%).

B

Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).

2. BASIC ITEMS FOR SERVICE

2.1 QUICK REFERENCE

A

Quick Reference upon Service Visit 1

Notes, PD/SD diagnosis, and methods for various settings

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 "7. DISASSEMBLY".

2 Attaching screws for the HDMI connector

When attaching the HDMI connector after replacing the Main Assy,
secure the HDMI connector 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

B

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:

Let the panel sit at least for 3 minutes after the power is turned off.

A:
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".

C

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.

When ordering service parts, be sure to refer to "EXPLODED
VIEWS and PARTS LIST" or "PCB PARTS LIST".
The mark found on some component parts indicates the
importance of the safety factor of the part. Therefore, when
replacing, be sure to use parts of identical designation.
