This ADDENDUM is made due to the new models P50X901 (DW3D), P50V701 (DW3D) and P50S601 (DW3F).
They are different to models P50H401 (DW3A), P50T501 (DW3A) and P50H4011 (DW3A). The Main difference is the panel,
the X/V/S models use "AF1" Plasma Panel and the H/T Models use "AE1" Plasma Panel. Software (Digital Main PWB) is also
different because of Plasma Panel difference.
Refer to Service Manual PA0224 when servicing X/V/S models in regards to other adjustments not covered in this addendum.
This ADDENDUM indicates only the differences and special considerations to be taken when servicing the X/V/S models.

ADJUSTMENTS
NOTE: The next adjustment procedure is only for the P50X901, P50V701 and the P50S601, refer to the service manual PA
no. 0224 for all the other adjustments.
POWER SUPPLY Vs, Va VOLTAGE ADJUSTMENT
Since Power Supply P#HA02202 is already adjusted by Manufacturer is not necessary to adjust any voltage.
Important Note: Please don’t move any control (potenciometer) on power supply since is already adjusted.
See Page 48: Please see page 48 for additional Power Supply Adjustment Information.
VIDEO COLOR TEMPERATURE ADJUSTMENT - BLACK AND WHITE MODE.
-Preparation
(1) Set the output of signal generator to white raster (Ratio: 100%).
(2) Component signal (480i)
Video level:
0.7Vp-p
SYNC:
0.3Vp-p
Set-up level:
0V
(3) Input white raster signal into COMPONENT input terminal.
(4) Set user control to Day (Dynamic) mode (Picture mode).
(5) Confirm that the mode is set as ‘Factory setting mode’.
(6) Aspect: 4:3 Expanded.
-Adjustment
(1)
(2)
(3)
(4)
Perform the following adjustment with the remote control.
Set the CRT color analyzer (CA-100) at the center of the panel.
Ensure that the adjustment parameters R/G/B DRIVE(B/W) are all set as FF.
After receiving the PC signal, reduce the value of two (or only one) of the RGB adjustment
parameters step down two (or one) among adjustment R/G/B DRIVE(B/W) and adjust the value
shown below.
Specification
Video Color temperature (B/W)
x = 0.335± 0.005
y = 0.343± 0.005
( Color temp? 5400K)
At least one of the data should be FF.
-Remarks
(1) Color temperature should be adjusted under the condition in which the screen is the brightest,
thus the initial value for adjustment is set at its maximum.
(2) Adjustment is made by reducing brightness only. Reduce the brightest color for adjustment.
(3) Video color temperature & Adjustment number are the same, but addresses in the memory are
different, thus there’s no problem.
(4) When this adjustment item is done through MMC slot, Sniffer Jig must be inserted after the set is
switched to Sniffer Mode. (the PC would have trouble if this sequence is not kept.)
