Alec, I hope that you can help me.
Some time ago my KN2000 suffered a power supply failure after some rather severe power glitches. I traced the problem to a blown fuse resistor in one of the power supplies and replaced it.
It has worked well but recently when first turned on it is horribly out of tune. It can be corrected only by doing a re-set using the menu but is again out of tune after turning off and then back on.
Doing a complete 'Factory re-set' at turn on does not do a thing.
I have the service manual for the instrument, so if you could point me in the right direction of where to look, I would truly appreciate it.
