[RTTY] Master reset for IC-PW1 CPU?

[Don Hill AA5AU]

The PW-1 went fritz tonight.  Turned it on a all LED's on the remote control
came on and stayed.  Unit would not power off but all functions seemed to work
like changing the meter and antenna inputs and outputs.  It even keyed up but
only at 500 watts.  The only way to turn the amp off was to unplug it from wall.

Plugged it back on and now no LED's on the control head and no functions.  The
meters light up and are setting at half way (both of them).  The unit powers on
and off now with the power button but that's it.

Bypassed the remote control cable and used the internal control cable, but no
change.

Any suggestions other than sending it back to Icom?  Was hoping there was a
master reset on the CPU but can't find it in the users or service manual.

Looks like it back to 500 watts to the Ameritrons this weekend...  such is life.
