I tested the power button and the touchscreen, both are in working condition. However, nothing displays on the phone’s screen even though something is supposed to be showing (I outputted the display to my computer).

I tried knocking and pressing the corners of the phone in case something is loose.

Is there anything I can do?

I’ve received a Xiaomi Mi 9T for screen repair, I’ve a spare screen and back for the phone, the screen comes together with the frame, I’ve moved everything to the new frame with the new screen and connected it all, once I tried to power on the phone nothing would show on the screen and the front camera (pop-up) which has a small dot on the side starts blinking red. The phone has been connected to the charger for about 10 minutes now, and no charging logo appeared. I’ve tried holding the power button, and volume buttons to see it I achieve any response at all but nothing. Any idea what can be the problem? I’ve never encountered this before. Thanks in advance!

Here’s how it looks.

Any suggestions what hardware needs to be investigated or replaced to fix this issue?

Note - mobile data and SMS still work, just not calls.

I can only find Mi 9T Pro parts and repair guides. As well as only a mi 9t pro in the devices i can choose on this site. Does it work out the same for both devices?

I have a xiaomi mi 9T (not pro but it’s the same they say).

I followed many videos, everything is fine, but i can’t remove the front screen, i heat, i went to 80°c on the front screen and it did not moved. It’s like the glue won’t melt. Do you have any idea ?

I already checked if there was any screw i forgot or thing like that, but there is not.

I really don’t understand why it work on their video and on mine it doesn’t

I’m facing an issue with my old phone. Specifically, I replaced its screen, but it’s not working as it should. When booting the phone, the logo appears for a fraction of a second and then disappears.

The phone boots normally into the OS, as I can hear the boot sound through the speaker, but the screen remains off. After conducting various tests, I discovered that if I disconnect the screen's flex cable and reconnect it to the motherboard’s main flex, the screen lights up and stays on without any issues with color or touch functionality. However, if I reboot the device, the problem reoccurs.

The screen is not original; it was purchased from a well-known international site.
What would you advise me to do?

Thank you in advance.
