[TenTec] Paragon is it dead?

[Louis Ciotti]

OK so I thought I was making good progress resurrecting a paragon, but now
I thing it may be "brain dead" .  It worked the last time I had it on the
bench, but now when that I have time to finish getting it back together,
when I turn it on all I get is random LEDs lit up, nothing and nothing on
the display, and no audio output.  The last time it was on the bench
everything worked, just needed to fix the headphone jack...

Did the processor or memory die?  Any thoughts on debugging this?
