I recently bought a broken Guitar Hero X-Plorer guitar on Ebay for $23 hoping to be able to fix it. After plugging it in, the Xbox wouldn’t turn on. This scared me a great deal to say the least. I looked at the power supply and the light was red instead of the usual orange. It had detected a fault and was protecting the console.
Knowing it was a problem with the power, I narrowed the problem down to two things. Either the USB cable was broken internally or the previous owner spilled liquid on the controller. Lucky for me it was the USB cable, an extremely simple fix. The +5 (red) wire was broken right were it starts to come out of the guitar, most likely due to the previous owner wrapping the cable around the controller.
If your X-Plorer controller isn’t working there is a good chance this is the problem. If you want to be sure, test each end of the USB cable with a multimeter. If this is the problem, all you have to do is cut the bad part of the USB cable out and reconnect the two good parts. The bad part will most likely be the thick rubber part coming out of the guitar.
To connect the two good pieces of the cable back together, twist the wires together, solder them, then use heat shrink tubing to cover the exposed part of the wire (you can also use electrical tape, but heat shrink tubing would be best). You also need to twist the outer part of the two good pieces together and solder them. Use electrical tape to cover anything that is exposed (should only be the outer part of the cable at this point). When finished, use zip-ties to make sure the electrical tape stays put and to keep the wire from moving around.
