The digitizer is responsible for converting your touches into digital signals. On the contrary, the display has two main parts, namely LCD screen and the digitizer. For example, if it is dislodged, your display will go black, but you can connect the cable to fix the black screen issue. If the cable that connects the display with the logic board goes bad, the display won’t show anything other than a black screen. Therefore, the logic board dictates what to show on display. The logic board is responsible for all the operations on an iPhone. They are iPhone‘s display and iPhone logic board.

Solution 2: Restore Your iPhone with iTunes.How To Know iPhone Black Screen of Death?.How To Know If The Display Is Dislodged Or Broken?.What Causes An iPhone Screen To Go Black?.This is the first time where I've felt that I've been let down. recently, I have purchased iPods, iPhones, iPads, and a MBPr.
They have ordered more replacement units, and I'll be notified when they come in. 4 duds out of the millions sold!? Who made these screens this year? Goddamit! Whatever, after showing me his own iPhone 6 and some floor models, I'm convinced I have yet another dud. This genius is less than receptive and he tells me that his manager says this one is within specs. But just in case, I set the brightness to max, and BHAM! Dark spots and lines all over the place. So I walk into the Apple Store again and I have another set of geniuses helping me. Fortunately, I get the notice the next day that they are available. So he tells me they are out of replacement units and I'd have to come back after new ones were shipped in. It was hard to explain, but the genius was very apologetic and made a comment about "10 million of these sold and you get the two bad ones." So he goes to the back to get another replacement unit, but comes back out and without explaining why "uhm, you don't want this other one either." OMG! This phone was worse! It was uniformly lit except that along the top it was lit in a wavy pattern. Wiping my phone and putting the sim chip into the new one, we power it on to set it up. He immediately agreed that it was defective and agreed to replace it.
I made an appointment and came to see the genius about 3 days later. I took it into the Apple Store but was told I needed to make a genius appointment. It made me squint a bit and gave me a headache just thinking about it (OCD). It made the text blurry and dirty looking. I would describe it as being about the size of a thumb print and it was mainly noticeable when there was black text on a white background. The 1st iPhone 6 I had was backlit well, but there was a very noticeable dark spot in the upper right hand corner, next to the sleep button. I've gone through 3 different iPhone 6 phones and they all have the same problem: Uneven Backlighting.
