  • iPhone 6 Plus Touch IC Repair w/Lifetime Warranty

iPhone 6 Plus Touch IC Repair w/Lifetime Warranty

May 30, 2017 28 Comments Written by Mike

If you’re part of the cell phone repair community, then I’m sure you already know about the iPhone 6 plus touch ic epidemic. Here’s my take on the problem.

Classic sign of touch IC disease...the gray flickering bar at the top of the screen

Classic sign of touch IC disease…the gray flickering bar at the top of the screen

In Apple’s search for the biggest, thinnest, most durable, longest lasting, and sleekest iPhone, they totally neglected the the rigidity of the iPhone 6 plus and the fact that it bends pretty easily. Since the logic board is held pretty firmly in place onto the frame with many screws, whatever bending that takes place with the frame also bends the logic board.  With the bending of the logic board, the ball grid array (BGA) chips seem to break free from the logic board leading to what the repair community knows as “touch IC disease”.

What is “touch IC disease”?  There are two chips on the iPhone 6 plus logic board that handle the touch functionality.  The two chips are called Meson and Cumulus to the repair community.  U2401 (Cumulus) and U2402 (Meson) as they are known in the schematics.

Silver rectangular chip is Cumulus and the larger black rectangular chip is called Meson.

It seems as though some of the balls under the BGA chip break free from the logic board when the frame of the iPhone bends thus causing intermittent “no touch” problems.  This problem has been an epidemic.  It’s happening at such an outstanding rate that most microsoldering repair shops can’t keep up with the demand to repair.

Oxidation evident under the chip

Apple really should issue a recall on the problem or perhaps, offer to fix the problem for free.  The problem is a design flaw.

The way to fix “touch ic disease” is to remove the black chip (Meson) using heat, run a microjumper (M1) to the damaged pad and put a new chip on.  The problem goes away once this has been done.  We’ve repaired hundreds of these phones in our shop with great results.  We now offer a lifetime warranty on this repair.

Here is a picture of the M1 microjumper that we discovered that fixes the touch IC disease problem for good:

Running the M1 jumper solves the touch IC disease problem

      I have the exact problem you just described on my IPhhone6Plus that I purchased in the fall of 2015. I broke down in the fall of 2016 just a few weeks after the warrantly expired. No fun How much to fix it with the lifetime warranty.

      Never replace the silver IC unless you’re certain that you have the black IC in perfectly.

    My son’s iPhone 6 screen freezes constantly, but there’s no flickering grey line at the top. Do you think it’s a different problem? Thanks!

      The iphone 6 does not display the signature flickering gray bar at the top, but the problem is the same.

    What is the typical turnaround time for Touch IC repair, from when a customer sends the phone to when the customer receives it back?

      Roughly 6-9 days from when you send it.

      Start with just u2402 (meson). If it comes back, then replace u2401 (cumulus).

Amazing work!!! Well I just got my phone back after giving the Microsoldering.com team a week to work on it. A month ago, I had dropped it in the salty waters of the Mediterranean Sea and it went black. I thought I totally fried it and lost all my vacation photos. This company brought my phone back to life. Cost me about half a grand with the screen replacement but whatever, I got a lot of beautiful memories back I thought I would never be able to see again. I was really skeptical about shipping my phone to some online-company in Virginia, but I took a shot and they kept great communication throughout. FYI Geeksquad and a few local repair shops said that this kind of repair was impossible. Well I wanted to write this review for MS.com because of how shocked and amazed I am from their work. Guys, thanks.read more

Fixed my IPhone 6S screen backlight after I tried to repair my own screen and blew it up. I actually saw a spark and smoke coming from the phone circuit board, then screen was super dim. I was about to throw it away, thought it was a goner. Then decided to send it to these guys and they fixed it. Very professional and these guys are legit. It’s worth every penny you pay. That was about 2 years ago, phone still working.read more
