How do I get the screen off my toshiba theaterview tv?

Trying to get the screen off my Toshiba Theaterview TV to clean the back.

If it's still under warranty, then don't do it, because you'll void your warranty. Otherwise, in general for most TVs, check the sides, there should be some screws pointing towards the front of the TV. They might be some sort of cover over the screws, just look for small shapes that you might have to pop out with a flat head screw driver. Have someone there to hold the front though because that's the heaviest part of the TV, and it will fall like a ton of bricks and break.
