This is the easiest way to get a working Guitar Hero cymbal – buy one!!!
My yellow cymbal was faulty and I tried to fix it, but couldn’t. I’m not sure why – maybe I killed the sensor in the process. So I did some searching and found an eBay stsore, Thumbmonkey, that sold various game bits and pieces – and they sold individual Guitar Hero cymbals too!
They’re based in the US so it took some time to get to Australia (ordered on the 16th Sep, arrived today 7th Oct). Looking at the cymbal, it’s in great condition, the yellow ring a little bit dirty. Does it work? I’ll have to go home and see. For me, the cymbal cost US$11.99 + US$17.64 shipping to Australia = US$29.63. At today’s exchange rate, that’s $33.39 AUD. Cheaper than buying a whole new drumkit (if that’s possible).
So, if you’re really stuck, cymbal doesn’t work, you’re out of warranty, and the methods that people have posted on the web don’t work, then just buy one…
