V23+++ Composite Cabinet Back

The WS-55813 and WS-65813 feature a unique cabi- net similar to last year’s WS-65712. It has a com- posite cabinet back that offers several advantages.

•Rounded edges in the back have a modern appearance.

•Unit construction gives it high strength.

•Low Weight - The 55” version is about 50 lbs lighter and the 65” version is about 100 lbs lighter than comparable models!

The disassembly procedure for the cabinet front dif- fers from conventional cabinets. Note how the Cos- metic Front Panel is removed. Refer to Figure 1-7.

1.Remove the Speaker Grille by pulling forward.

2.Remove 2 screws (a) securing the Cosmetic Front Panel.

3.Slide the Cosmetic Front Panel 1 inch to the right, then lift away from the TV.

4.Remove 6 screws (b) to remove the Board Front.

5.Unplug the LF connector.

6.Remove the 4 screws (c) securing the Screen Assembly.
