2 chips have blown inside. You more than likely cannot do the repair yourself as it needs specialist soldering experience as the chips are very very very small. They blew because of either of the following: 1/ you plugged in the wrong charger , most reson is by accidently plugging in a phone charger letting 12v in instead of 5v. ... 2/ A voltage spike came from your car generator or starter motor . 3/ The car charging lead or the mains charger has gone faulty and put out too high a volatge.
