Walt, good to hear from you again. You helped me out quite a bit getting familiar with this set when i first purchased it. If i remember correctly you have the 46HX83.
Should be the same deal then. Speaker panel just pulls off. I started at one side on top and get that clip loose 1st, then the bottom one on the same side, then the other side top and bottom and then the middle. This exposes the silver fascia behind the speaker grill. I believe there were 8 screws total holding this on, 2 above and below each speaker. These are torx(sp?) head screws, i don't know what # they are, but fairly small. All screws by the way, that go into wood on this set are the same size torx screw. All other screws that go into plastic are the same size screw only with a 1/4" hex head and phillips. After the bottom silver fascia is removed you can get to the screws holding the panels between the screen and the speaker section. The panel that has the drop down door with controls and the power button has 2 or 3 screws holding it in. They are all along the bottom of the panel. It has wires running into it obviously and not alot of slack. However, it doesn't weigh very much so i just rested it against the set. I did not disconnect these wires as you can see in the pics. The other panel is just for looks. Same deal here, 3 screws at the bottom(there are alot more mounting holes on all parts mentioned so far but not all of them had screws in them, so yours may have more or less screws to remove). NOW THIS IS IMPORTANT, there is a small piece of MDF type board right behind these 2 panels, it's about 1" tall and the same thickness by about 18" or so long. When removing the screws holding in these 2 panels that board is very loose (it actually comes out, and i took it out until i was done)and could fall out on its own, so i would remove it and set it aside. Now all that's left is removing the screws holding the screen in place. All the silver fascia around the screen and what's available to see from the front below the screen is all one piece. I removed the ones in front 1st, then the sides from behind the screen then the top ones from behind the screen. THIS IS IMPORTANT AS WELL. There is a wiring harness attached to the screen from the set. My harness is visible in the pics. The wires are red and the harness(plastic) is white. This needs to be disconnected to be able to get the screen off the set to store while you are working on your set. I was able to disconnect mine before removing the screen however there was a type of wire loom or holder that had to be opened to get the loose end out of the way. Would be a good idea to have another set of hands around for this part(i used my wife, yes, it was that simple).
We each grabbed an end of the screen and carried it over to a spot on the floor where i had laid a clean sheet down.Well, that's it for the screen removal, goes back together in the reverse order i just explained of course. And keep in mind that this is a do at your own risk project. I can't be held responsible for anyone's set but my own,but in saying that, it really wasnt that hard to do.
I did not restack my screens or remove the glare screen as i have total light control in this room. I only wiped the back of the screen off with a microfiber cloth, same type i use on the shiny front side. I'll post more about the focusing and cleaning either today or tomorrow, i've got a few things to get done here, hope this helps you guys out .

edit: In looking at my pictures again,you can see that MDF mentioned right below the 2 cpanels between the screen and speaker section. It actually comes loose when you remove the screws on the silver fascia at bottom of screen. Sorry about that.

and here's the link to the page it came from, with pics of the cleaning of the lenses and such:

SOURCE: toshiba 57H83 and no longer get any sound. Any

Most often No Sound with Toshiba 57H83 is:

1. TV has a Sound on-off switch on the input panel at the rear of the TV. Very hard to see, black on black. Used to turn off speakers if you use a separate or external sound system for speakers. Usually gets moved while connecting hd cables or dusting and vacuuming in cramped space at the rear of the TV.

2. Someone accidentally changed Sound settings with remote to CC (closed caption) or SAP. Turn off in sound menu and save preference.

3. Sound input plugs from external cable or sat box unhooked or wrong input.

Toshiba 57H83 no sound fault is not common. If you still have no sound, get local service.

Or troubleshoot yourself to determine if Tuner, IF, processing, sound demod, switching or sound output circuit is smoked. Then make an installation plan.
