Ben-Some components get microphonic - i.e. - they pick up vibration where 
they shouldn't  - sometimes gently tapping suspected components with a 
plastic pen might highlight any component that is faulty. You shouldn't hear 
any effect unless there is something faulty. If there is a cold solder 
joint, it might show up that way too-Mickey

Boards do not make noise. It might be a compoment on the board. Your service 
person should be able to trace it!

OR see the machines on ebay, the one for $149 has a motor problem, probably 
has a board that works…
2 hours left, no bids yet!
$149 is about one hour’s worth of a tech’s time!.
