Original stands can generally be purchased from Samsung's parts website. Sometimes pedestals within a brand are interchangeable. The F8000, however, will NOT work with a pedestal taken from the F7100. This is due to the way the stand attaches to the TV -- two small vertical struts connect the the TV to the base on either side of the TV. This differs from The way Samsung's other stands attach.
