Scan lines and distorted lower screen

My lower Nintendo DS screen was blank, but the backlight was on and the touch panel works, so I replaced the display to no avail. I then tried turning the lower screen’s potentiometer to adjust the contrast and was able to get some display, but it’s only a partial display and some scan lines show up. I tried this with the replacement lower screen as well, but I got a checkered/plaid red/green line pattern.

Are the screens toast? Should I try replacing the pot?

Zoom-in on reverse side of board. Maybe C14 looks worse for wear, and there's some corrosion between C15/GSP1:

@dstevens17 this “lower screen’s potentiometer to adjust the contrast and was able to get some display,” sounds like a recap may be the right thing to do. Sure, you could also change the potentiometer but those do not often fail. after that re-evalaute and see what you got going on. Right now it’s all pretty much a guessing game.

@oldturkey03 thanks for the tip! Any idea which cap it might be? My guess is either C11 or C12, but I'm having a hard time finding a spec sheet for the DS.

@dstevens17 that is one of our biggest challenges. Schematics! or the lack thereof? Post a couple of good pictures of your board and lets's see if we can figure something pout. You will have to edit your QUESTION and follow this guide Ajout d'images à une question existante

@oldturkey03 done! Note that the P5 ribbon cable socket clamp is partially broken, but it still holds the ribbon in place and the DS still boots.

@dstevens17 that board looks really good. I think for now you can postpone the recap. Let's see if we can find some schematics. VR1 VR2 trim-pots for the display ????

@oldturkey03 no luck finding a schema, so I've no idea which caps and resistors are relevant for the displays aside from the variable resistors -- what about them? Haven't messed with VR1 since the top display looks good, messed around with VR2 to get *something* to display on the lower screen, and haven't touched VR3 (and dunno what it does).
