beadyp , Look in the charge port and blow/pick out(carefully) any dust/debri that may be causing an issue also look in the port for any bent pins and straighten very carefully with a tooth pick. Try a different compatible charger/cord to see if that is the issue. If port is found to be bad/loose/damaged , this is really not a repair for the inexperienced because the charge port for your device is soldered to the mother board and the heat generated could cause further damage if not very careful. I will post a link to a tear down guide to get you inside the camera to check the charge port and will also post a link showing what is involved in repairing a mini USB attached to the board if you would like to attempt. If not wanting to do the repair yourself have a good camera/computer/cell phone repair shop have a look and estimate repair. Good luck.
