Where you can get it repaired depends very much on where you live. Whether it is economically viable is a different matter - with equipment of this age, parts may no longer be available, nor qualified technicians to perform the repair. Camcorders have moved on a great deal in the past ten years - replacement may be the only option.
You can often download a manual for almost any equipment by Googling the make and model followed by the word Manual, then follow the appropriate link(s).
hi,
the cassette maybe damage or the tape may be wound up on the pinch roller if your cassette is not needful, cut the reel and pull it, after taking out the cassette out, the remaining piece of tape remove from the roller.
