My Mac suddenly showing up horizontal lines in almost half of my Mac. Nothing happened before my Mac become lie this (pressure/fell down). Its was doing fine 2 days ago. How can I fix this? And why is this happen?

On the back of your display is some circuitry which converts the signals coming from the logic board into what the display needs. From this logic are ribbon cables which connect to the actual glass plate of your display these connections is what has failed (LCD TAB Error). Sorry to say, you really can’t fix this without replacing the display.
