SERVICE MANUAL

This ADDENDUM is made due to the new models P50X901 (DW3D), P50V701 (DW3D) and P50S601 (D W3F).
They are different to models P50H401 (DW3A), P50T501 (DW3A) and P50H4011 (DW3A). The Mai n 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 Pl asma 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.

Important Note:

See Page 48:

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)

(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) Perform the following adjustment with the remote control.
(2) Set the CRT color analyzer (CA-100) at the center of the panel.
(3) Ensure that the adjustment parameters R/G/B DRIVE(B/W) are all set as FF.
(4) After receiving the PC signal, reduce the value of two (or only one) of the RGB adjustment

P#HA02202

Please don’t move any control (potenciometer) on power supply since is already adjusted.

Please see page 48 for additional Power Supply Adjustment Information.

Video level: 0.7Vp-p
SYNC: 0.3Vp-p
Set-up level: 0V

parameters step down two (or one) among adjustment R/G/B DRIVE(B/W) and adjust the value
shown below.

is already adjusted by Manufacturer is not necessary to adjust any voltage.

-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’sno 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.)
