Electronics Repair Questions? Ask an Electronics Technician
Hi, thank you for contacting JustAnswer.com. My name is***** will do my best to provide the right answer to your tape player / recorder question.
I suspect that a drive belt (rather like a small black rubber band) that powers the tape spindles, has snapped, owing to age or other factors. This commonly leads to whirring noise when turned On, without any tape movement, owing to the drive belt being needed to transfer rotation of the drive motor to the spindle, to turn it and thus move the tape.
Opening up its interior, and looking for a snapped, or perhaps merely slackened and loose, drive belt, probably black in color, would be what I would do if I were working on this problem.
If you would rather not do that yourself, then please tell me how old the Denon is (in case it might be within warranty) and if you need locations of appropriate repair shops in your region, to contact, please let me know your local town or city and region, also.
It is good to determine what belt, or what size, before ordering one.
If you meant, where to go to get the new belt put into the mechanism, that would depend on where you are located, please.
