Black screen after screen replacement
Is it possible to replace a broken ribbon cable that is part of the screen ?
It looks as if the cable to the smallest contact was damaged when replacing the screen.
苹果官方于2015年9月25日正式发售iPhone6S A1688/A1633机型。 此机型的修理方式与先前几代差不多, 需要螺丝起子及撬棍工具。 同时也适用GSM or CDMA/16, 64 or 123 GB/ 银色, 金色, 深空灰色, 玫瑰金色等机型。
HeyMargit. This is classic iPhone 6s backlight filter damage. No question.
You can do an out of warranty swap at Apple for $299 USD, or have a microsolderer change your backlight filter. It is a straightforward repair and quality shops offer no fix = no fee to look at it. We just fixed one from Norway last month. A shop called RepLab--they can give your more info since they've seen this exact issue before.
Don't blame the electrician--most of the stuff on the internet about how to change screens fails to stress how important disconnecting the battery first is before iPhone screen replacement. The 6s seems to be highly susceptible to backlight failure from simply pulling the screen while the device is still under power.
Sorry for your luck, but definitely repairable.
No, its not possible to replace the cable on the LCD without very very expensive equipment.
In saying that, more commonly, the back-light diode, filter, or driver ic is blown.
Did you disconnect the battery prior to changing the screen? If not, I wouldn't mind betting you have bigger issues than an LCD cable :S
This happens on a regular basis when an esd strap isnt used, my theory is a static build up in the phone through handling. The fix is easy... disconnect the battery, remove all lcd connectors (prox sensor,backplate (where applicable) and lcd connectors. while the battery and connectors are still disconnected hold the power button for 20 seconds and release it. (this drains any static in the system). Finally connect all connectors for the lcd and reconnect the battery. If the lcd is in working order it should power on once again.
