SERVICE MANUAL
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.
