Search here (team iriver, iRiver FAQ, etc.) And at misticriver.net. I remember in my lurking before h1xx, that I read a troubleshooting bit about the 2 LED's and what they may or may not tell you. A few folks (riverpietro?) Are trying to learn to rehab death by improper charger....
Your' is 5v center pos? VERY common killer to h1xx & h3xx.....
Good luck,
Joe
