I came to the forum today because my MS40 freezes up on start up and I was hoping to find a solution. Now I see the Audya is also freezing up. When my MS40 freezes it is on start up. I have to open the case, press on the chips, they crack a little, then it works again. But this is too unreliable to use for live gigs. Does anyone know about fixing this? I think it is related to grounding. It is worse when I use an extension chord. Thanks for any help you can provide. Much appreciated.
