Yes they do repairs through the Geek squad, at home or in store. Call your local best buy for specifics because I believe there is a size limit on TVs that they will repair.
If you have your purchase history and receipt, can you tell if it has a warranty? You may be able to get a replacement. Otherwise I'm not sure if they repair TVs. I know they do computers but you'd be better to call. Not a reliable brand but they are extremely cheap so cant blame you.
Should be able to
