Other than checking all the connections going to it for signal it is likely a shop repair.
The nature of these sets is someone must open and inspect them and check for voltages missing.
At that point it becomes a guessing game---try the boards (purchase them) and see if a bad board.
It is always possible the front screen unit or display has failed which is fatal cost wise.
You have to weigh the cost of repair, age of set and cost of replacement in this.
The only way anyone can KNOW which board is bad is to actually remove and replace it----most shops look at it and shoot you a high estimate.
let me know if you have questions.

Check to make sure that your speaker wires are not pinched. If the wires look good, then your main board is the culptrit.

Video section has become compromised and no longer functional. Audio being separate from the Video may work perfectly, but the Video portion sustained damage to the circuit board or the inline safety diode blew. If any parts of the Circuit Board fail, you need to replace the mainboard. The cost to generally fix a circuit board is usually more than the replacement cost for a new unit. Check all fuses or circuit limiters inside the TV and if there are no shorts, burned parts, or obvious smells on the mainboard, transient current may have trickled in and damaged sensitive electronics. Have a professional Technician do tests to locate the source of the problem.
