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
without tools.
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.

Before detaching the stand, unplug the AC cord from the AC INPUT terminal. Before performing work spread cushioning over the base area to lay the TV on. This will prevent it from being damaged.
With the hex key that came with the television stand remove the four screws from the bottom back of the television and remove the stand.
If you also wish to remove the post from the stand base unit you can remove the four screws that attach them.

Page 85 of the manual has it, and can be downloaded here.

Here's what it says to do:

1. Place the TV face down on a soft cloth or cushion on a table.
2. Remove four screws from the back of the TV.
3. Separate the stand from the TV.
4. Cover the bottom hole with a cap.

There is a picture in the manual that indicates that the four mentioned screws are the four on the bottom back of the television.

Good luck!

Remove the three screws from the back of the stand.
Remove the four screws from the bottom of the stand.
Looking down at the bottom of the stand, push the four protuding clips inwards (not easy - you may need to gently ease them with a small screwdriver)
This unclips the oval base and allows you to unscrew the remaining screw inside the stem of the base

With the tv laying flat on to the screen, remove the two screws in the recessed holes. Then remove the two screws above towards the input panel, one under AUDIO-L/AUDIO-R and the one under HDMI-1. The stand should easily slide out.

My insignia 26 inch dvd combo TV stand can be removed by removing the access cover to your input connection. There are eleven black phillip-head screws. The three bottom screws also hold the plastic base cover in place. Remove all eleven screws and pull the stand out from below. The four philip-head screws on the back center of the TV is for the location of the wall bracket mount. Good luck.

There's likely a plastic cover on the back of the swivel stand. If so, remove it and you will find four to eight phillips screws. Take them out and the stand should come free. If there is no plastic cover, then there should be some screws in the back cover that go through the back cover and into the support. Remove the screws and gently remove the stand. Good luck. David
