The screen of Black Shark 3 is not displayed, charging has current, and the boot vibrates. In this case, the screen is broken. Is the machine okay?

If you try to call in, can you get a call from this phone? If you can get a call, it means that the function of this mobile phone is basically normal.

If there is no display, then the display screen is likely to be broken. If you just change the screen, the cost is not very big. If the motherboard and other circuit boards in the design are damaged, the cost of replacement will be very high. Might as well scrap it and buy a new machine.
