Unique logic board issue?

Hi all,

I am having an interesting issue with my 6+, and I can't find related issues or solutions across the vast internet - so I need your help.

My 6+ does not turn on. A few months ago, my screen was heavily cracked and the display began to flicker. Over the course of a few weeks, the screen would turn off/dim in certain areas of the screen depending on the pressure/location of my finger. It became so bad that the screen would only turn on if I twisted the shell of my phone (yes. it would only turn on if I twisted the opposite ends of the phone, similar to wringing the water out of a wet shirt).

So, I went a purchased a new screen thinking that was the issue. But, I did what all of us are guilty of: I bought a third party screen (because $129 is absurd for a 3 generation old phone). The screen worked great for a few weeks and then the phone went completely dark. I thought it was the off-brand screen, but I took it to Apple anyway to get a 'professional' opinion. They employee reaffirmed that my screen was a god-awful quality (guilty), but he would change out the screen with an OEM one to be sure it was the screen. After boasting about their special calibration tool, he returned with a frown and announced even their screen wouldn't work.

So, the next thought was my logic board was fried. Somehow, even after little use, my phone killed itself. So I decided to do surgery on the phone. I have discovered that if I use my screwdriver and firmly press down on the bottom right screw of the metal plate that houses the ribbon cable connections underneath, the phone will turn on. Note, the phone restarts with the Apple logo every time; it doesn't just turn the screen on.

Any idea what is happening/how to fix this?

Thanks!

Please stop applying pressure on the bottom right screw!

If you continue to do that, you will feel the urge to tighten it down even further. That will cause extreme damage to your logic board, otherwise known as Long Screw Damage. I suspect your phone already has that and it occurred when you replaced the screen. The phone worked for a few weeks and then, because it's a 6 Plus, probably flexed enough to damage some internal traces.

It's clear you have a logic board issue. If your lucky, it's a Chestnut or Backlight issue. Still, this has to be looked at by an experienced micro-solderer. The "Geniuses" at Apple are really only genius by name and other than installing screens, don't really know much about the hardware inside the phone (they are very good at software issues though).

There are many shops worldwide that do this so you shouldn't have any problems finding them. There are several reputable micro-solderers patrolling this forum.
