1st Rule: Never ship a Lasonic
2nd Rule, see rule 1
OK, Lasonics are made of cheap, flimsy plastic, the power transformer quite often breaks loose from it's mounting while in transit, this sounds like what has happened here, it can make a terrible mess of the sensitive electronics inside, hopefully yours hasn't suffered this fate.
Chris (LASONIC TRC-920 user name) is in Ojai (North of LA I believe) may be able to help you if you ask him nicely in a PM.
Beware, Chris is certifiably insane, as well as being a very nice guy.
Good luck.
