MY TV IS SMOKING BURNING INSIDE AND IT IS ONLY A

Can the TV be replaced? Certainly. Stores are full of replacement TV's.

Can the parts in yours that are smoking be replaced? Possibly. Some parts are generic and can be found at companies that sell TV repair parts. But other parts have to come from the manufacturer, and they are not always available or are too expensive to make the repair worthwhile.

Should you get this TV repaired? It depends on what kind of a TV it is (you didn't give a make or model), its age, how much damage was done by the parts that smoked, and what it would cost to repair compared to replacement.

The best solution is to have a TV technician check the set and give an estimate if it's a large-screen or otherwise costly model (or you just really want to keep the set). Or use this opportunity to replace the set if the difference in price is small.
