My W-30 makes a sort of tone coming from within the body of it. It is not musical (can be heard without being connected to anything) It only does it when it's on..I am wondering if this is normal, or if I can do something about it? Any help would be apreciated..Thank you.

Martinbaker,

It sounds like it could be your LCD display. My D-70 makes a high pitch whine, as do a lot of Roland products from that era with the larger LCD displays. Just a thought.

I know this noise from my W30 very well. It's produced by the LCD. Sorry, but I don't think there's anything which can be done about.
