It sounds like a power supply failure. TV's aren't really DIY repair jobs. If I had to guess I'd say the TV may have at least one defective capacitor in the power supply.

There are sites that offer replacement boards but that can be costly and not always easy.
I'm surprised the standby light is not flashing a fault code.

Have you tried unplugging the set from the wall outlet for a minute, then plugging it back in and trying it. I have a newer Sony that occasionally refuses to turn on via the remote or the control on the set, and unplugging it briefly gets it working again.

That's a newer model TV --- is it still under warranty? If you paid for it with your credit card, many credit cards double the factory warranty. Definitely worth looking into.
