Hi,

I bought my SD1+ about 9 mths back every now and then when the keyboards has been on for say 45 min I get a sharp crack out of the right hand spaeaker, its coming from the SD1 since I have changed over the speakers to prove it, if you are playing with the volume up it frightens the life out of you and you shake for a few moments, it only happens once, anyone else had this?
