Hi,
I cannot get the initializing led to flicker on my kdsp2. When I do the
voltage checks, I really cannot make sense of it, versus the schematic.
I have double checked that the right parts are installed in the proper
orientation, re-checked for bridges, etc. I have checked that none of
the control board components are rubbing against it and I am currently
blind to the problem.
The voltages on U1 are not right.
Pin 5 should be 0 and its 4.96v
Pin 14 should be 5 and its 0v
Pins 15-19 should be 0 and they are all 4.96v
I saw a post from January with these same indications but never saw an
answer.
Any clues?
