It's doable, but there is a learning curve. Most professionals have either cracked a display or damaged one of the bonded ribbons or address board(s) on many an early repair. Out of the several thousand flats I've done, I've lost about 15 or so.
You have nothing to lose really, but if you disassemble the display, set up your work area so the TV is about a foot away from the wall or some other barrier.
As you remove the mask, the retaining pieces, the 3 to 5 polarizer sheets, then finally the display, you can stand them up against the wall in order. Reassembling is simply lowering everything back down in the same order (and more importantly) in the same orientation. If you get a polarizer sheet upside down or backwards, it will affect the picture.
It's a good idea to pick up several small suction cup grabbers (harbor freight) to support the display as you lift it up and out of the light box. The display is a lamination of two plastic sheets surrounding a thin glass layer where the LCDs live. This glass is so thin it couldn't support it's own weight without the plastic shell, but even with the plastic, it can still flex and crack if you try to lift it with a finger nail. So several suction grabbers and a friend will lift the display out of the frame with as little stress as is possible.
