Always preform a hard reset before attempting any repair. (Home and Power button together for 15-20 seconds) usually this is an issue with the SubPBA Flex. (Charge port and headphones jack) Start with a Software reload to verify it isnt a software malfunction. (This will erase all of your user data) afterwords, if it didnt fix it, replace the above suggested part. if you replace this component, and it continues, it is likely a board failue.
