No...sorry. I didn't mean to make you type out that long
explanation; I hope it helps someone else. The actual *input* for
the AC cable is messed up. Like on the cheap older keyboards - I
have to position the jack that goes into it just so to get it to
work. Is there a way to fix this?
The first thing that I would do is open it up and see where the jack sits on
the board and wiggle it around a little to see if the solder joints are
loose. If so, just hit them with a soldering iron and you should be good.
Although you really can't be sure what needs to be done until you open it up
and have a look.
