They do repair smart tvs. My tv had sound but no picture. They came out to my house and picked up my tv within 24 hours after I called them. They brought my tv back the same day they picked it up and it was working great. Within a month or so I started seeing white spots. I called them back well within the 90 day warranty period and they told me someone would be coming by to take care of it but no one called or came by. I called but now all of a sudden I can't reach anyone. I would not recommend Excell
They repaired my Smart TV, a Vizio 55 inch. Did a great job too.
I believe they do. they do an excellent job.
