Help: iPhone 4 screen is not working
I was wondering if you could help me with something. I tried replacing the display on my i4 the other day (something i've done a couple of times before). When I put the new screen on it wasn't displaying correctly, so i put my old screen back on and that stopped displaying correctly. So it looks like I've damaged something (probably the mainboard). Any ideas how to fix this?
I've double checked to make sure the LCD cables are plugged in.
I've attached a photo of what happens when I turn it on.
