LCD display horizontal lines
So I replaced the screen of my iphone a couple of days ago, thinking it'd fix everything and such. Didn't do it correctly and I wonder if I broke the cable in the process or if it's a motherboard/connector issue because the screen has been flickering, horizontal lines and the icons on the screen are 'doubling'. So...would a new screen assembly do the job or do I need a new logic/motherboard?

Additional: setting it to high brightness made it go dark
Is this a good question?
