Fizzy,
Why is it "dead"? Does it have brushes that are worn out? Mine came with a spare set. If brushes are worn, could be worth trying to get replacements, ebay or maybe specialist supplier – try Google? Try to get at least an estimate of likely repair cost, it may prove more economical to chuck it and get a new one. Is it newish?could you make a faulty goods claim under consumer law or via the Cr Card issuer with which you bought it? Good luck
