• Preparation for adjustment
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.
• Procedure for adjustment
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.

• Measurement equipment
1.Color analyzer (CA-100 manufactured by MINOLTA)
1.Signal generator (ASTRO DESIGN VG-828D)
• Service mode lists
Caution: 1. Setting functions of Display section are displayed with yellow OSD.
2. Be careful not to set DATA in the yellow-covered OSD menu. The setting will be
memorized.
3. items are not required adjustment or are banned adjustment
• Measuring procedure
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 values of 6500K, 8000K, 9300K, 10000K and 13550K to following values
of X/Y.
W/B standardized values:
6500K+8MPCD 8000K+8MPCD 9300K+8MPCD 10000K 13550K
W/B 01234
X 0.3133±0.003 0.2944±0.003 0.2838±0.003 0.2806±0.003 0.2684±0.003
Y 0.3297±0.003 0.3100±0.003 0.2981±0.003 0.2883±0.003 0.2700±0.003
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)1/25Window (255/255) input Y (luminance)=45cd/m
