Well I still have the turn on problem.  After I read what I sent you 
last, I thought better of taking the front panel connections for 
granted, so after I got home from work tonight I removed the front panel 
and exercised the various connections and put everything back together.

It wouldn't turn on.  So I did some random gefinger poken and just as 
randomly the radio turned on.

Let me review what I know about this nuisance:

1. When pushing the "Power" button, I hear a small relay click and my 
power supply indicates that the rig is drawing about an amp.

2. However, no panel leds light and there is nothing on the LCD display.

3. No tapping, nudging, or any other "therapeutic" man handling of any 
parts appears to improve the situation.

4. And then with a random push of the "Power" button...voila, the radio 
comes to life.

5. I reloaded the firmware code a couple of times at least.  I'm using 
the KUSB adapter from Elecraft and it is running the latest driver from 
Prolific.

I don't know what else to mention, but I'm afraid to turn the rig off 
because I'm afraid I'll never be able to turn it on again!
