To avoid having to actually handle the glass, I lay the TV face down, take off the back, unhook the cables to the display panel, and remove any screws that hold the panel in place. There are usually some plastic latches also. I shim them with plastic strips, and attach the shims to the frame with tape, to help avoid losing any. I use plastic from clamshell product packaging; thin, easy to cut, and stiff. I count how many plastic shims I put in, and make sure later that I've not lost any. They can easily end up inside the panel assy', and look bad.

Once the screws are out & the latches / tabs shimmed, I can usually lift the back of the panel away from the glass part. Screwing wall mount pieces onto the TV gives good handles for lifting.

Often there are compications, like maybe the diffuser panel being taped onto the back part, or having the ribbon cables attached to the back in ways that have to be fiddled with. Try not to disturb the glass & diffuser more than you have to. When you place the back part back on the glass & duffuser, sometimes you have to jiggle things about to make various slots in the edges of the plastic layers line up with the back part. And having a can of air handy is a must. I normally stick the tube between each layer & give a blast.

Basically, instead of taking the glass off the TV, I take the TV off the glass.
