It is mostly due to a defective screen. But, if a new screen does not solve it like @refectio said, note that this model is prone to:

- Touch controllers separating from the board due to hard drops or bending of the housing; reballing or replacing the touch controllers is necessary; "reheating" is not.

- The circuit powering up the screen is partially shorting (very common for this model). Replacing the failing components is necessary.

最有帮助的答案

You could simply have a defective screen. Some replacement screens are fairly low quality and have a limited useful lifespan. It could be a logic board issue (first rule out with a known-good replacement screen) if your case has suffered multiple drops or bending.

Let us know if that is the case.
