Well it depends on what happened to it. You might want to trouble shoot with your customer service but honestly if you think it is going to cost more than it's worth then you have to basically get a new t.v. That will be the better option for you for sure.
This depends on what the problem is. If you are missing a button on the t.v. then you can replace it but going to the electronic department and asking for a missing button.
This all depends on the problem at hand and how much money it would cost to repair it. I would look at the current TV market compare features and figure out if it is worth replaceing it or repairing it.
The only way that I know how to repair on is to send it to the company that made it. I don't know if it's worth it, I would see if someone can tell you how much it would cost.
