iPhone 5 - vertical bars, shadows on the top of the LCD -> NO Zebra problem

[Deltaone1]

Hello,
I have a problem with an iPhone 5, on the top of the display there are some white bars/shadows.

Also I can not drag down the notification, as in the top where the shadows/bars are the touch have no function.

The same Issue as this guy here: https://www.youtube.com/watch?v=lm1q8SUW-Jg

Its not the Zebra problem. I already changed the caps C156, C149, C351,C350,C353 and the XW35. But without any working solution

Maybe somebody here have a idea what wrong with that phone


hope to here from you guys
thx

vertical stripe problem with no touch always problem with AVDDN circuit specifically negative boost supply look at u15 and surrounding components. the components you mention to the rigt side c156,c149, this is often good so you must look to the other left side of the avddn circuit way

ANYTIME YOU HAVE PROBLEM WITH HEAVY CONTRAST IN VIDEO, SHADOW PROBLEM WITH ICONS AND LETTERS, 'GHOSTING" IN VIDEO, BLURRY VIDEO INVERSE COLOR PROBLEM, THIS PROBLEM USUALLY WITH THE NEGATIVE BOOST CIRCUIT WAYS (ALSO AVDDN) SO YOU SHOULD CHECK AND CHANGE DIODE D5, L40, C434, AND LASTLY U15 8 PIN BGA AND WHOLE AVDDN CIRCUIT. IF YOU SHORT LCD_BL_CA TO THE NEXT PIN OVER ON THE LCM DISPLAY CONNECTOR, AVDDN(4TH PIN TO THE LEFT) OR IF AVDDN SHORTS TO GND, YOU WILL DAMAGE U15 AND THIS PROBLEM HAPPENS WITH MESSED UP DARK SHADOW DISPLAY
