1. Slide the DIP switch (S3201) No. 8 of P board to on

position with no silkscreen mark 

r.

2. Connect a digital voltmeter to the following terminals of

G board.

VS voltage=G board TP1701 (VS)-TP1502 (GND)
VD voltage=G board TP1501 (VD)-TP1502 (GND)

3. Connect a AC cord in DISPLAY UNIT.
4. Perform the adjustment in 10 seconds after connecting

the cord.

1. Slide the DIP switch (S3201) No. 7 of P board to on

position with no silkscreen mark 

r.

2. Confirm the lighting of SONY LOGO LED.
3. Adjust the VS voltage to the following voltage value.

VS voltage       of proper value for each model.
Ex.) VS proper value=185V thru 185.6V at 185V.
(Check the proper value with a seal on upper left of
panel unit. Refer to right Fig.)

4. Adjust the VD voltage to the following voltage value.

VD voltage ±0.3V of proper value for each model.
Ex.) VD proper value=64.7V thru 65.3V at 65.0V.
(Check the proper value with a seal on upper left of
panel unit. Refer to right Fig.)

5. Check a Fan rotation.
6. Slide the DIP Switch (S3201) No. 7 of P board to the off

position with the silkscreen mark 

r.

7. Slide the DIP Switch (S3201) No. 8 of P board to the off

position with the silkscreen mark 

r.

8. Disconnect an AC cord of DISPLAY UNIT.
9. Reconnect the AC cord in one second.
10. Assure that “POWER ON/STANDBY” LEDs is

flashing amber.

1. Color analyzer (CA-100 manufactured by MINOLTA)
2.  Signal generator (ASTRO DESIGN VG-828D)

1. Dab the W/B adjustment jig (CA-100) at the glass face

of the panel.

2. Connect the Signal generator (VG-828D) to the DVI

terminal.

3. Input All-white signal and set the picture mode to

DYNAMIC.

4. Select”PNLCTRL” in the service mode menu and set “0

WBNO” at “0”

5. Select “SCNR” “SCNB” of “PDPWB” in the service

mode menu, and then adjust following W/B standardized

 +6V
 –0V

values of 6500K, 8000K, 9300K, 10000K and 13550K
to following values of X/Y.

6. After adjusting the values, at the values of the “SCNR”

or “SCNB” exceeding 128 (initialize value).
1) Reset a lager value of the “SCNR” or “SCNB” at 128.
2) Set the White Balances with the last of items and
   “SCNG” to the X/Y values above.

7. After the above step, when these item are nonqualified

following conditions, set the largest one at 128 and
readjust the White Balance with the last two item.
1) No one of “SCNR”, “SCNB” and “SCNG” exceeding
    128.
2) Confirm the item value 128 at least one item.

8. As a result above, input the sequential number of value

to the “SCNR”, “SCNB” and “SCNG”.

9. Repeat the same step 5 thru 8 for the W/B 1 thru 4 after

setting the “0 WBNO” at each W/B number.

10.Input following signals from the Signal generator (VG-

828D).
1) All-white signal (255/255) input
    Y (luminance)=45cd/m

2

 or more

2) 1/25Window (255/255) input
    Y (luminance)=45cd/m
