Got this solution off another forum and tried it. Worked liked a charm. I was about to throw my tp out the window.
"If you can't pull a charge from the TP wall plug charger, and you know the cheap TP USB cable hasn't gone bad, here is the next thing to try: Go get a standard, low power, USB charger (like for your cellphone, or if need be use your computer's regular USB port). Plug the bugger in on your wimpy little USB cell phone charger and let it trickle charge at that low, 1000mAmp rate for a couple of hours and see what happens. I revived mine doing this, after the TP wall charger did nothing for 14 hours. It appears that if the voltage drops too low, the only way to charge it is using the standard USB voltage and not the higher voltage normally fed out by the TP wall plug or Touchstone. Definitely try this before you go through all the trouble of pulling the thing apart."
I hope this works for you. I just used an htc usb with the htc wall charger. Juiced the tp just enough
