Yep. When I tap the screen, it restarts, but sometimes I need to press a hard key to get it to come back on. Once it restarts, it works perfectly. It just shuts down after (n) seconds, whatever the LCD display time is set to. Pressing any hard key or icon resets the time until shutdown.

Since I can see the putput from the boot process, but not get it to recognize any kind of input, I thought of a cable problem, but that still doesn't explain the strange shutdown. BTW, both problems started at the same time. (The remote started rebooting and I lost the ability to communicate with PRontoEdit).
