Need a stand for a Samsung PS-42D5S

SOURCE: how to remove the stand from samsung LCD TV

Place the tv on its screen flat on a soft surface,
you need to remove all the screws, not just the stand one marked.
Lift the back panel and then you will be able to slide down the stand, when you have removed the back cover you will also see where how your wall mount will fit to the chassis.
Place all the screws back on the back lid.

SOURCE: Can not remove the stand to mount it on the wall

If the Aquos 46 is anything like the Aquos 42, the monitor is attached to the base with machine screws (bolts). They are located in the lower back portion of the monitor, probably need an Allen wrench to loosen and remove. Once that is done, the base can be removed from the monitor. Best way is to lay the monitor face down on a tabletop padded with foam, a quilt or blanket, etc to protect the screen as you work. Remove the stand from the monitor, not the monitor from the stand; it is easier and safer that way.
