Neuros Technology Forums

I have a Neuros 1 which is nearly 3 years old.  Lately it won't hold a charge (an overnight charge would give less than 30min play time).  I figured the battery was old and was about to have it replaced when I noticed that while charging if you touch the ac cord where it plugs into the Neuros the battery voltage number starts jumping around.  It would change from as low as the 330s to as high as the 370s.  I know from my other Neuros around 415 to 420 should be a full charge.

It seems to me there is probably a loose wire or bad solder joint in the backpack where the ac plug is.  Can I fix this myself?  Is it worth trying or can I send it in and have it repaired?
