This ADDENDUM is made due to the new models 42HDX62A (DW1-UA), 42HDT52A (DW1-UA) and 42HDS52A (DW1-UB).
They are different to models 42HDX62 (DW1-UA), 42HDT52 (DW1-UA) and 42HDS52 (DW1-UB). The Main difference is that
"without A" Models use "A2" Plasma Panel and "with A" Models use "A3" Plasma Panel. Software (Digital Main PWB) is also
different because of Plasma Panel difference. Dimensions of both Family Models are SAME.
Refer to Service Manual PA0208 ("without A" Models) when service "with A" Models. All Adjustments are same. This ADDENDUM
indicates only the Differences, Updates and Special Considerations to be taken when Servicing either Models.
