A couple of months my niece attempted to connect something on one of the outlets in our home. When she attempted to do this, a spark blew up and smoke came out of the outlet. At that time it shutdown the power to half of the house and I went to the breaker and turned everything off and then on...the power came back up and no problems remained. 2 days ago, during the day, the television turned off while I was watching it and no one attempted to plug anything in on one of the outlets...REALLY STRANGE. I thought this was going to fix it, but obviously, it didn't.
Want do I need to do and how do I fix?
If I hire someone, what's a fair price to pay?
