Lost power to outlets and lights?

Reset all the breakers, sometimes they are not in the middle when tripped. You may have a bad breaker in the panel, especially if it's a 15 amp breaker that had been close to it's load limit for a long time. Find the circuit and get a new breaker to snap into the panel. An overloaded breaker will heat up over time and eventually fail. If you aren't competent to have your hands in a live AC line voltage panel, call an electrician that knows what they are doing.

And, consider the possibility that the outlet receptacle may be bad or a lame electrician used the push in wire connections.

The location of the outlet would determine it's being a GFCI outlet or not. If the wiring in the house has an outlet on the GFCI, it may not be in the breaker box but in the garage or laundry room , or a bathroom. Go to any outlets with the GFI test button and reset them all. That should cure the problem. I've just never seen a GFI outlet in a living room for a television. Make sure it's not on a power strip that popped it's overload fuse.

Test the outlets for power. I suspect that you will find an open neutral/return line in one of the devices. Typical problem with the stab in the back devices that are used in home wiring because they are fast to install. Locate the dead items in the system and check the one nearest to the electrical panel. A plug in type tester is a good device for all homeowners to have along with an inductive type tester. I dislike the digital meters since they give false readings of power present.

Knowing the age of the house helps discern which circuits need to be GFCI protected also. It seams every couple years more crocus get GFCI protected and now AFCI protected also. Also as previously suggested you may have lost the neutral in the outlet when he pulled down his game effectively killing the circuit. (Possible the hot lead also yet less likely as they tend to find some place to go to ground and thereby trip the breaker.) Good luck

Check your breakers again and read the cheat sheet that lists which breakers go where. They aren't always obvious when they trip. After you've found the correct breaker, firmly turn it off and then on again. (Also, unplug everything affected BEFORE doing this.)

Circuit Breakers are mechanical devices. It would be a good idea, once a year, to shut off and turn back on, each breaker in the box. It keeps them "limbered up" and functioning properly.
