Im having this exact issue as the op. It all of a sudden turned off. I do have the red light on the bottom of the tv on but the usual standby light in the corner is off. I try holding the power button down on the tv and i can hear the what sounds like the one connect box making a noise but not sure if thats normal or not. Still have some more research to do but i hope i dont have to have a tech come out.
I just bought this tv about 8 months ago when my old(2016) Samsung JS8500 starting having a bad edge bleed problem and the screen just kept getting darker and darker over the weeks where you could barely make out what was happening on the tv.
I'm sorry to hear that, if you do not have the TV plugged into a surge protector and this is still happening while being plugged directly into the wall outlet service would be recommended please send me a private message with your full model and serial number so that I may look into this?

The power button would be located underneath the Samsung logo.
Is your standby light on, off, or flashing?
If the standby light is on:
It is normal for the standby light to be lit when the TV is turned off (as long as it is plugged in and receiving power). But if the TV still won't turn on when you try, the only thing left to rule out is the remote.
First, try turning on the TV without the remote. (The Power button's location varies depending on your TV's model. If you are not sure where it is located, see your user manual.)
If your TV still will not turn on, service is required.
If the standby light is off:
Without using the remote, press any button on your TV except Power.
If anything appears on the screen when you interact with the controls, this confirms your TV is on. You can continue troubleshooting by going to the next step.
Unplug the TV for 30 seconds, and then plug it into a working outlet.
If the standby light comes on (and doesn't flash or blink), your TV is receiving power and will probably turn on now just fine. This means there is an issue with the original outlet, or the surge protector if you were using one. If it still doesn't turn on even though the standby light is now on, continue troubleshooting in the section for TV won't turn on, and standby light is on.
If the standby light comes on but flashes or blinks, or if the standby light still doesn't come on, service is required
If the standby light is flashing:
Surge protectors may eventually wear out and stop providing the necessary voltage for your TV. If you're using one, make sure that you rule this out before you set up service for a flashing standby light.
