Hardware help! why my 3ds xl top screen has a blac&white line filckering randomly?

[Razhad]

it came out randomly, mostly when i play FE Awakening, AA Trilogy, and SMT DS SH.

this happens after i repair my 3ds charging port and analog on local store (i'm in indonesia, so nintendo support is out of question), how can i fix this mess?
---------------------------
update

i could confirm this only happen only in few games
i tried playing NSMB2,Pokemon Y, Luigi's Mansion, FFEX, Story of seasons, zelda a link between world and i dont see any of those problem
---------------------------
update again here's a video of that screen



notice that there's a black-white line came out for a second on half to left screen

nb: i'm a cfw user, rxtools to be exact. just in case if this happen because of that or anything related to that (emunand etc)

Sounds like the ribbon cable for the top screen isnt in all the way or has a tear in it.

Yes. Make sure all the ribbon cables are set in properly as well. But if the lcd cable has a rip/tear in it, you'll have to have a new screen installed.

When I turn it on, the blue power light goes on for 3 seconds, then the bottom screen flashes on for a split second then you hear a *pop* sound, then the system shuts off. Upper led ribbon was damaged which made my upper screen need to be replaced. Ypu have a different problem but the same solution as me.

No idea, also, no need to be impressed XD I butchered the disassembly and damaged the upper led even more. (Didn't matter cause it was broken) I had to fix soo many things, it was cheaper to just get a new one and swap the motherboard.
