It absolutely depends on what went pop, and why, which only an examination by a TV repairer can tell you.
It cold be just an internal fuse, or maybe the power supply has blown, both of which are cheap to fix, or perhaps the main board is a smoking ruin, which isn’t.
Have you got a meter you can put on the power supply, see if it is still working? See if the mains lead to it is still working - it could be as simple as that fuse.
You could ship it off to Sony to look at:-

but as a set now six years old, best find out if it is economic to repair.
See what Sony will charge to look at it, or maybe get a local repairer in, get an estimate. That might be your best first bet.
There’s one on eBay for £290, to give you some idea of the cost of replacing it exactly, but that would be absurd (as is that price!); current 43” TVs, comparable and better, start below £380, if yours can’t be economically repaired,
My favourite bedtime reading is a Sony product manual…
