Dan,
The MCU is apparently not completing the initialization process. The
INFO 201 should be shown only once (and not in normal operation). It
will be shown once after a Master Reset. It should finish in about 30
to 40 seconds.
The first thing to check is the soldering on the Control Board.
Reflow the solder adding a bit more (to add a bit of flux). Use a hot
iron (750 degF) and dwell on each connection until you see the solder
flow out onto the solder pad and the component lead - that should take
about 3 seconds, but if it takes up to 5, no problem.
73,
Don W3FPR

Need some help here.
Been working on my K2 S/N 7770 and got to the point where power is first
applied.
Upon pressing the Power button, got the INFO 201 message, but it just remained
on the display. It never went away and I never saw the ‘7100.00c’.
Turned power off and then cycled it back on. Now, the display is simply blank.
Nothing.
I reset the K2 (pressing 4-5-6 then powering up), and the INFO 201 came up
again with the same symptoms.
Would appreciate any thoughts on what might be happening.
