[sdiy] Korg PS-3300 help?

[Fahl, Romeo]

Have you checked what the power supply is doing?  It could be that
there's an old cap that's giving up the ghost.  Just a guess...

	Can anyone offer suggestions to cure a bizarre fault on a
PS-3300?
	The instrument plays fine, and sounds wonderful..... for about
ten minutes.  Then, if a three or four note chord is played, it goes
berserk.  Lots of notes trigger at random. A great abstract sound.......
but...!
	Switching the machine off then on after 10 - 30 secs brings the
power light on, but no sound and NO LEDs flashing.
	Switching it off and on again after that usually gets it working
properly again....... but only for 5-10 minutes before the next crash.
	 
	The 60-way keyboard lead contacts have been cleaned; no
improvement.
	 
	Any thoughts or suggestions gratefully received.
	Peter
