Some one needs to open and examine the power supply for voltages and see if any or all are present or gone.

Depending on what is found boards are going to have to be purchased, installed and the set tested to see if one or more are bad.

This can be and usually is an expensive process.

We have the same TV. In settings for sound you need to select the port directing where you want sound to play. It may be that it is currently setup to play to a sound bar.
