For large appliances, including TVs, alam ko warranty repairs are automatically home service and/or pick-up/drop-off.
Anyway, maybe it's just "soft-bricked", and just needs to be power-cycled..... unplug, wait 30 seconds (or until the Standby LED goes out), then plug it back in.
Sometimes the OS or an app crashes and the TV becomes temporarily unresponsive. If so, a power-cycle will often fix it.
I have a Samsung smart TV that is maybe 8 or 9 years old. I only have had to unplug it a couple of times when it got stuck in an app and wasn't responding to any button inputs.
