I just experienced it on my mother's BLU Advance 5.0, and how I tell it's on is that the boot screen shows, and the screen dims right after that. When I power off by long-pressing the power button, it restarts and does same.

While on, I can still hear the sound when I press the volume keys, and when a call comes through, I can receive it by guessing where the button is on the screen and sliding it (which means the touch screen is working, but for some error, the screen is just black). The notification light also keeps blinking when there's a missed call...

Hi @ Kaby Digital,

Try starting the phone in safe mode and check if the display stays on.

If it stays on when in safe mode then a downloaded app may be the cause of the problem. You will need to uninstall the downloaded apps, one by one and test the phone in normal mode until it tests OK. When it does test OK the last downloaded app that was uninstalled was the culprit.

If it still doesn’t stay on when in safe mode hard reset the phone using the phone’s hardware keys and check if the problem is still there or not. You may need to remember or write down the phone’s Google account user name and password before you reset the phone as you might need it once the phone has been reset

Be aware that a hard reset (aka factory reset, factory restore) will erase all your data and downloaded apps. It will restore the phone to its’ default or last system updated operating system.

Once it has been reset to factory default check if the problem is still there.

If it is still there then there is a hardware problem. The phone would have to be opened and the problem further diagnosed

If it is not there then the reset has resolved the problem.

I resorted to a reset. My files were on an SD, and I could afford to do the hard reset. Thank you for your assistance
