After Display Replacement Lines Apeear on the Display.

After a display replacement, I get horizontal lines on my phone’s new screen. The phone also has issues in dark conditions as the phone acts like it has 8 dimming zones. I was grounded during the display replacement ( Common Issue ). As the display is powered on the lines progressively turn from light grey to black. I don’t know what to do about this, so do y’all have an answer?

From what you are describing it may be one of the following:

Bad connection of the LCD cable. Did you try disconecting it and reconecting it?
Bad LCD panel. It may of have been defective from the start, or damaged in shipping or during the repair process.
Pry damage of a component near the display connector on the motherboard. This one is easy to make and hard to repair. If you have any way to magnify your view, have a carefull look at the components near the connector. If one was accidently pried off you will see 2 solder pads with the solder that appears rough and ruggged. If so that components need to be reinstalled. Be carfull, there are often No Stuff pads. Which are pads that never had anything installed on them in the first place. You can tell those appart when looking at them, the solder will be round and puffy vs rough and rugged.

The nice thing about pixel screen replacement is that you don’t need to access the full motherboard to replace the screen, which really limits the potetial problem areas.

Hope this help ( I would not be too worried about static discharge problem, and it very rarely an issue)

Thank you but unfortunately, none of these fix the issue. I've disconnected and reconnected the display about 15 times, have cleaned both sets of pins, and have verified that no pins are broken on each of the connectors. I did replace the battery of this phone but have not touched the motherboard other than using a spudger to remove the display, battery, and force sensors (I don't know a better word for them); taking off the midframe I see no visible damage to the motherboard under a magnifying glass. I have contacted ifixit and have stated the replacement process. Thank you for your suggestions.

The best,

-Chris
