I have a TSU2000 that has I bought new approximately 2 years ago. The other day the screen started responding sporadically, osft buttons getting stuck in the on position, screen not responding at all, etc, but it still worked more often than not. Just the other day it finally quit responding at all. I have tried all of the usual fixes ie: tried leaving the batteries out over night, tried updateing the firmware. Tried downloading a new .ccf file, etc. and the screen still isnt working, you can wake it by pressing the backlight button, but none of the soft buttons will respond at all. My thinking is that the screen is shot, any other ideas. If not does anyone know where I can find a TSU2000 screen, I have been looking but have not been able to find any screens yet. ANy help would be greatly appreciated.
