missing horizontal pixels on display screen
I have two missing horizontal lines of pixels. The first is just below the tool bar and the second is almost half way down the screen. I ran the self test for the calculator and confirmed that the lines were missing. Is this a hardware problem or software problem. How can I determine which it is. If it is a software problem will a reset fix it without removing the factory installed programs. But if it is a hardware problem would this be an easy fix.
Is dit een goede vraag?
