Hi, i have instruction on removing your base stand.
Removing the Pedestal Stand
1) Carefully lay the front of the unit face down on a flat,
cushioned surface such as a quilt or blanket. Leave the stand
protruding over the edge of the surface.
Note: Extreme care should always be used when removing
the pedestal stand to avoid damage to the LCD panel.
2) Remove the jack pack cover on the back of the TV to expose
the pedestal stand screws. The jack pack cover can be removed
3) Remove the four screws shown in the diagram below. This will
allow removal of the pedestal stand.
4) Once you have removed all four screws holding the pedestal
stand in place, remove the pedestal stand from the TV by
sliding the pedestal stand away from the TV.
