Cello,
I contacted Harman/Mark Levinson about a tune up on my 23. I was quoted a flat rate regardless of the extent of tune up or repair necessary. I was told the flat rate would cover what ever it would take to restore the unit to as new performance. I don't think this covered cosmetics, but not positive on that aspect.
So, the answer, it seems is yes, they do service them. I just sent an email to the tech support e-mail on the website and recieved the info in a day or two.
