Oh, man, I am in exactly the same boat. TSU2000/01, screen shows half black, half blank. Still boots, and the touch screen still responds, but I finally got the itty bitty torx and took it apart. The faded label on the display pcb can barely be read, but it's the same part number. I was hoping someone had a source for the exact replacement, but I've only been able to locate the -A part as well.

Life without pronto is not worth living... please help!
