Either the charging port is busted or the Tristar chip needs replacement which requires micro-soldering work done on the phone. You can find reputable repair shops that offer a no-fix no-fee model to get them to fix it for you. You can quickly test tristar by unplugging the battery then plugging the charger in and see if it shows apple logo or not, if it does not then the tristar chip is not. Usually I would test another charger port if possible to rule that out.
