My simple advice is to get a multimeter and learn how to use it. Check
for shorts between your power rails, and maybe take your problem A-190
and the 5V regulator out of the case and check for shorts between the
power pins there as well. If all this is too much to figure out on your
own, then take it to an electronics specialist and let them do it for
you. Of course, if it's still under warranty you could send it all in
for service.

Best!
