Black screen and no sound

I have 2018 Samsung un50nu6900f smart TV 50" 4k uhd

It won’t turn on anymore, it has only red light on at bottom.

when I try to turn on via either remote or via manually pushing button on TV, it makes very low sound for couple seconds, (like bird chiming / tweeting ), thats it.

no display or any sound at all. tried resetting by 60 seconds power button press, power recycling but no luck.

Anyone able to fix it or have any suggestions please ?

Thank you for participating in the Samsung Developer Forum. However, this is not the correct forum for end product bug reports, questions or concerns. This forum is for 3rd party developer issues.

I would recommend you use the Samsung Members App for feedback or post at → Click on Explore Tab → Click on Community.

Did you unplug the TV for 5 minutes?

Because end user questions disrupt developer discussion this thread will be removed but I’ll leave it a bit in case a developer can help.
