Monitor problem There is a small black rectangular box that goes on and off in about 7 second intervals with a message in white letters that says Menu Locked on one interval and Menu Unlocked on the next. This happens continuesly and has been going on for quite some time. In addition, periodicaly another black box will appear that has the the icons for the brightness controls and etc.
Odd. The manual doesn't mention anything about that.
It almost sounds like one or more control buttons is partially shorted or leaky.
That can happen if a foreign substance got in it or it was stored in an unheated garage or shed for a long time, etc.

if it does not go away on its own, try pressing the menu button one more time, or scrolling down to exit. if you're in a submenu, hit back until you're at the main menu then wait. if it doesn't go away, scroll and select exit. if it's a plain black box, try removing the power cable from the back for 10 seconds, and plugging it back in again.

remove the OSD Lockout message, release the Menu button (if something
was pressing against it), and press and hold the Menu button again for
about 10 seconds - until the message goes away. If the OSD Lockout
message does not go away, the button may be stuck or the hardware behind
the button might have become defective.

This may be because the resolution that is set in your user profile when you log on has been changed to a resolution not supported by the monitor. The best way to fix this is by going into Safe Mode (press F8 as the computer starts to load Windows) and change it to a lower resolution once you get logged in. 1024X768 is a pretty safe resolution to start with. Then restart and see if that fixes the issue.
There should be buttons on the monitor that will help you with menu issues if you don;t have a remote for it.
You also might want to Google the correct monitor,, as the one that you posted does not exist.

If you're working on the computer when that happens, it's not probably a power setting. Try to update your BIOS to the most current version at the toshiba support website (support.toshiba.com) & see what happens. Fixes the issue most of the time
