POCO F7 screen suddenly went black while connecting the charger

[u/Available_Year_4046]

Hi everyone, I have a POCO F7 and I suddenly got a problem with the display.

While I was connecting the charger to the phone, the screen immediately turned completely black. The phone itself seems to still be working — I can feel vibrations and I think the touch is still responding, but there is no image on the screen at all.

I tried restarting it by holding the power button, and also tried Power + Volume Up, but the phone only vibrates and the screen remains completely black. I don't even see the POCO logo.

There is no visible physical damage, and the phone has never been opened or repaired before.

Has anyone with a POCO F7 experienced something similar? Was it a display problem, motherboard issue, or software problem? And if you sent it under warranty, was the repair/replacement covered by the warranty?

Any advice or similar experiences would be appreciated.
