May be i'm wrong but do you check the parameter of your patches?  I 
had a similar problem with my poly MKI.  I don't have a back up 
battery, so when the poly was power down I loose my patches and the 
parameters was all messed up, strange values appears and the poly made 
crazy noises. If it is the case you just have to put back the factory 
patches into your synth. Hope it will fix your problem.
Good luck
