I'm writing here because, although I didn't see my question answered elsewhere in the forum, this seemed like a great community of informed and helpful folks. So here goes: I am trying to repair my Sansa e260 4 gb mp3 player. The headphone jack was only playing out one ear, and even then it was cutting in and out. I opened up the player, found a explanation of how to fix the problem, and went about trying to solder the headphone jack's pins back into place. HOWEVER, one of the pins would not stick to the board, and being new to soldering, I pretty much just tried to solder it harder. At one point, I was trying to clean existing solder off the place I was having problems, and the location got singed a bit. Now I can't get any signal from that point at all. It is a little black, but the damage is localized to the small area the headphone attaches. Did I irreparably damage the board, or can I clean it off or scrape away some of the burn. The device still powers up, just no signal from one headphone. I don't want to do any more damage than I already have If worse comes to worst, I'll just buy a broken one off ebay with a cracked screen or something and combine them into a single working mp3 player. Any help is appreciated, thanks!
