Most things I own have been out of their warranty for years.. So, no matter what it is, if it's not going to work anymore, then I'm going to take it apart and see what I can see. You'd be amazed at how many things can be fixed once you get in there and see!! or perhaps you will find that they are never going to work again no matter what.. Either way, you're better off..
Good job, BellaBoo.. Saved yourself a good many dollars!!
