1. CONTRAST OF MISCELLANEOUS PARTS

NOTES:

Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List.

A

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%).

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

1Rear 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".

2Attaching 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

Bwith an electric screwdriver, the screw heads may be damaged, in which case the screws cannot be untightened/tightened any more.

2.On parts replacement

1How 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".

C

3.On various settings

1Setting 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)

1.Digital Video Assy: Transfer of backup data

1Select {PANEL FACTORY}, {ETC}, then {BACKUP DATA}. (After entering Factory mode, press [MUTING] once, press [ENTER/SET], press [j] seven times, then press [ENTER/SET].)

2Select {TRANSFER}, using [l], then hold [ENTER/SET] pressed for at least 5 seconds.

3After transfer of backup data is completed, {ETC} is automatically selected, and the LED on the front panel returns to normal lighting.

2.MAIN Assy: Execution of FINAL SETUP.

1Select {INITIALIZE} then {FINAL SETUP}, then press [ENTER/SET]. (After entering Factory mode, press [MUTING] three times, then press [j] four times.)

2Select "YES", using [l]. Then hold [ENTER/SET] pressed for at least 5 seconds.

3After "FINAL SETUP IS COMPLETE" is displayed on the screen, turn the POWER switch of the main unit off.

3.POWER SUPPLY Unit: Clearance of the accumulated power-on count and maximum temperature value

1Select {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.)

2Press [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.
