I just found this thread searching for 'touch pro black screen death'. Specific symptoms included the screen not rotating immediately when I slid out the keyboard, the screen being black but backlit when I turned it on (intermittently at first, then permanently), and very rarely the display being corrupted (thin grey horizontal lines/bars. Started after I rotated batteries (I have 2 batteries and rotate between them). Swapping back to the other battery seems to have improved (but not totally fixed) the screen-black issue. Sliding the keyboard back seems to trigger the black screen (and may have caused the unit to dump power once).

My suspicion is a loose cable from the main unit to the LCD module - that would account for all observed behavior - if the cable for the LCD is above the battery compartment...
