• 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.

• 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.
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.
