Hi - it's hard to tell what's wrong just through your description.
There's obviously a short-circuit somewhere upstream, but the very best thing you can do (IMO) is visit your neighbourhood technician / repairman.
It could be something simple - but you need to take it to a pro to check it out. (BTW, Marantz ain't that expensive nowadays )
