TV no longer comes on?

My TV (Panasonic) no longer comes on. It also no longer lights up and all cables are plugged in. I have already checked this several times. Is there maybe a reset button like a laptop? Or maybe another option? I would be very happy to receive an answer.

How old is he? (Vlt. Has he just had his best years behind him…)

If the power supply fits, the TV will be defective.

Yes is already 5 years old but I made it out and then he didn't answer 1 minute later

I could well imagine that some fuse or something has blown
