1. Power the set down.
2. Hold the eject button on the drive while you plug it back in and power it back up.

Tv went off and won' come back on.

Most likely you will have to replace the power supply. It is a very common problem especially in newer electronics. You can test it with voltmeter or multi-tester. They tend to get worn capacitor inside the power supply due to cheaper parts
