I can't know the operating similarities between your SA 60 and the DV 60 I own, but I've got to believe it has to be something in the settings that is amiss. There are a lot of settings to choose from, try going through them again, and see if you've missed something.
Other than that, it may be a problem with the transport mechanism. I was able to replace the optics in my DV 60 on my own, it's not too big a job. The easiest way is to remove the face plate (and the lid), the mechanism is then easy to remove and replace. Contact Teac of America, they probably have replacement parts in stock.
Best of luck, regards,
Dan
