Zipp, I don't think anyone has mentioned it and sorry if they did cause I just browsed through the post, but anyway, if the LCD contrast is all the way to the right, you won't see anything on the TranzPort screen. Try this
1. Press the Backlight button to turn off the back light (if you have it on, otherwise jump to step 2)
2. Press and hold the Backlight button and turn the wheel to the left. The LCD should say "Adjusting Contrast", keep turning to the left.
If that's it, the numbers should slowly start to appear on the LCD and continue turning the wheel and holding the backlight button until you are satisfied.
Hope this helps cause the Tranzport is a genius invention worth it's weight in diamonds :-). No home recordist should live without one (you can tell I'm in love with mine)
