Greetings
I would suggest looking up Authorized Service Centers for Levinson.
There are are few throughout the USA and overseas. Give anyone of them a call about your issues. If anyone can fix it it will be one of the Authorized Service Centers. Levinson has not supported fixing their equipment for years. What a shame.
I had my ML 39 CD player serviced at The Service Bench (Authorized Services Center) a few years ago. They did ok on the CD player. I don’t think they are still in business.
