iPhone 5 no backligt/no display - GSM-Forum

iphonerepair12 · 04-05-2014, 18:06

I've here a water damaged iPhone 5 with no backlight. When I got it, the backlight was working, but after ultrasonic cleaner some of the components were missing (it really was bad corroded, especially in the zone with the LCD connector).

FL26 was missing (jumpered)
FL24 was missing (jumpered)

Now C17 is still missing

At the test point for the backlight (TP19 I measure 0.22V,
0.078V TP18 and 0V at TP20)

How to solve this problem ?

FIXED

Just do a hard reset (hold power and home button for 20 seconds)

Ok, it only works when the display is clicked into the frame and the backlight is flickering a little, any solution for that?
