[TenTec] Paragon logic board

[Mike Bryce]

Hi, Bob, 

no I have not tried that yet. it is kind of a bear Getting that PCB in and out. 

If I recall that's c5 on the logic board. Right?

I am not sure that is the problem. I have tried turning the radio on by  the  power supply and seeing if I can get the thing to reset. No joy.

There is no display, and sometimes all the LEDs are on, and sometimes all the LEDs are off

I suggest using  one a bit larger up to a 10 mf to assure things start in the correct sequence.  This just slows things down a bit during initialize.
