Query: Model GR-D30U

I've owned a model GR-D30U for less than two years. Yesterday the camcorder just quit powering on. The DC will not work, the battery will not charge. It simply will not turn on at all. Worse, I have a tape in there that I cannot remove without a hammer. The store I bought it from wants $100 just for "diagnosis." Just another case of expensive disposable electronics. My choice next time will not be JVC, a brand I used to trust.
