My screen is black except for an off white bar sweeps about about a 1/3, goes away and keeps repeating
My screen is black when I press the power button except it tries to slowly turn white but
stops a third of the way up the s
sreen and starts again - and again etc. I tried holding the power button and the home button but to no effect.
Does anyone know how to remedy?
Thanks
