Components having special safety characteristics are identified by a ! on the schematics and on the parts list in this
Service Data and its supplements and bulletins. Before servicing the chassis, it is important that the service technician
Read and follow the “Important Safety Instructions” in this Service Manual.
This ADDENDUM is made due to the new models P42H401A (DW3C), P42T501A (DW3C) and P42H4011A (DW3C).
They are different to models P42H401 (DW3C), P42T501 (DW3C) and P42H4011 (DW3C). The Main difference is the
Panel, the "A" models use "AE1V" Plasma Panel and the non "A" H/T Models use "A5" & "AE1" Plasma Panel.
Dimensions of both Family models are SAME.
Refer to Service Manual PA0225 when servicing "A" 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 "A" models.
