Did you attempt to root the tablet or install a different bootloader? If so, try again because it hasn't worked. If not, something has been corrupted, try to do a factory reset. Normally achieved by turning the power off, then turning the power back on while holding the home key and either the volume up or down button until you see an android.
If you factory reset you lose everything. So if the option is there, first try the to clear the cache and dalvik cache.
BTW, did you try the reset button on the edge of the case? Stick a pin in it. Try that first.

Probably because you don't normally turn it off.

Have you tried plugging it into the charger? If it's plugged in, the screen should dim but not turn completely off for at least 10 seconds. If it doesn't work, try covering the light sensor on the front of the tablet, so that the screen will brighten until you can change the backlight setting in Menu -> Settings -> Display.
