6 Plus screen flickering after replacement?

Hello all,

I've noticed a flickering around the border of about five 6 Plus screens that I've installed on customer's phones in the past couple of weeks. I've tried re-seating the ribbon cables with no luck. I'm having this issue with multiple suppliers so I'm wondering if this is a known problem in the industry? I've been repairing the 6 Plus for a couple of years now and haven't had this issue in the past. Any chance anyone could shed any light on the matter? Thanks in advance for your help!

P.S. I'm aware of the 6 Plus "touch disease", and the symptoms I'm seeing aren't in line with those of touch disease.

There are different quality backlights suppliers fit to iPhone screens. Copy backlights (may have minor flickering like you say, sometimes it does not completely light the screen evenly) and original backlights (no issues).

I stopped repairing phones a year ago, but used to refurbish the screens and always used original backlights because of this. Due to the parts market being so competitive, most iPhone LCD refurbishers use copy glass (edges not rounded properly, no oleophobic coating), copy bezel (lifts over time, not flush or fitting in phone easily), copy backlight and sometimes copy LCD (tienma, etc). This is to cut down on cost, but it will obviously have quality issues, as opposed to original parts being used.

When these were newer, nearly all parts in the screens were original. Over time, companies have manufactured copy parts to cut down on cost, which is likely why you are having this issue recently. Try a different (slightly more expensive) supplier to test the quality, or send broken screens/buy excess screens from an iPhone LCD refurbisher, who uses original parts during the manufacturing process.

@reecee , thank you for taking the time to reply. Do you have any suggestions for reputable suppliers?


Not entirely sure since I haven't done these in ages. Google "sell iphone cracked screens" and contact the companies that come up, usually they sell refurbished screens with original LCDs (check first obviously).

Could also try China, before refurbishing these I used to sometimes buy screens from a company called carvitech, can't vouch for them now though, since haven't used them in over a year.
