Disklavier

Is there a disklavier tech in Florida? I'm on the central Atlantic coast,
have a grand E3 with a DKC-850 (installed less than a year ago, might still
be under warranty?), where after it boots, there is a loud humming sound,
sounds electrical. Just started all of a sudden, has been working great
(well, kind of great, I can't connect to the Internet with it anymore).
Atlantic Music in Melbourne (where I bought the piano) has not had a
disklavier tech for years, I left a message for Accurate Piano out of
Orlando yesterday morning but nothing yet, he might be off this week, any
other options?
