Their Geek Squad does TV repair service. They have come to my home on two occasions to service my 50+ inch televisions. Both were under warranty.
I think you should call them And ask. My Best Buy does do TV repair. They have a company that does the repairs that works out of the Best Buy store. I don't know if that is all stores though.
No most tv repair businesses long been gone since the days of Blockbusters and VHS. Good luck on your search i know of one in the area called Steve's look him up. In Hartford
