Bad display driver.....replace phone.
The display, itself, makes contact with the driver PC board via a round
conductive rubber ring around the display. There are hundreds of
conductive rubber layers insulated from each other across the round part.
One side of the rubber lays against the PC board edge contact. The other
against the barely visable contacts embedded into the glass of the LCD
If this rubber "gasket" gets deformed, even a tiny bit, the wrong PC board
contact connects to the wrong LCD display contact as they are very close
together. Leaving it sitting on a hot seat in the sun inside a locked up
car is a good way to trash it. The display will do as yours does or may
have gaps in the scanned pixel display from missing contacts.
Opening the display and removing the LCD glass panel, then inspecting this
rubber gasket for misalignment can correct the problem.
It's not for the non-technical or faint-of-heart. Users keep insisting on
making it smaller and flatter and exascerbates the repair effort.
As at the top, you may also have a bad display driver IC, the electronics
that turns image data into a scanned system of high voltage and grounds to
drive the fancy display....How far was that last drop test?
Has the moisture sensor turned black?
