What is the model number? Most Eumig sound projectors have a separate fuse on the sound board. It is usually a fast-blow 2.5A size, so it is not uncommon that the fuse could be bad. I would suggest checking the film path too, and make sure that the sound head is clean, and that the gate is secured to hold the film against the sound heads. In the S900 series, this 'door' opens from the bottom, and can easily be loosened and drop open, which would not be noticeable while running films. Thankfully, Eumig projectors where manufactured to very high standards, and are well worth servicing. You will find many on ebay too. The most common trouble, is that the rubber belts deteriorate, and this may also cause problems related to sound and sound flywheel operation. Belts can still be purchased very cheaply as well. Good luck.
