Apple Watch Series 6 has black screen

Hello Apple Users.

I am having a black screen issue on my Apple Watch Series 6 Nike Edition. Please read the issue carefully.

What actually is happening that I can feel my watch is ONN by sounds and vibrations. But it just black screen.

The Touch is also working while on black screen.

When I do the force restart, the restart happens but there is no apple logo or display is shown. Just black screen but nothing else.

The watch screen opens only when I Shutdown it by mirroring it on my iphone.

And keeping it on charger overnight.

Then it just works for another 6-7 hours and suddenly it goes to black screen again.

I tried :

-Force restarting

-Factory reset

-Erasing it completely

-Overnight Charging

The problem occurred when I upgraded to watchos 9.3.1

But as we all know thet we can’t roll back.

If anyone having the same issue, plz give solutions.

Force restarting is not helping in my case.
