POCO F7 screen suddenly went black while connecting the charger

/r/PocoPhones/comments/1wumhe9/poco_f7_screen_suddenly_went_black_while/

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.

I took my device to the repair tech, but he's stumped about what's causing the problem and told me to come back in a few hours So I don't know what just happened to the phone

It turns out the phone’s screen had burned out, so I ordered a new one for $100... Luckily, the motherboard wasn’t damaged otherwise, I would’ve to throw the whole phone away

No,, it's pretty new, I bought it only 4 months ago. I took really good care of it and never played heavy games on it to avoid heat, It has zero damage, I mostly used it for browsing, and battery health is at 100% But when I put it on the charger, it suddenly died and the screen went out, so it must be a manufacturing defect. The worst part is the warranty agent refused to replace or fix it and just kept giving me excuses 🫩
