screen bleeding?

[halcyon flower]

hello friends, this is my first time modding a gba and i thought i did everything correctly, except over time the screen hasn’t been functioning properly. the best way i can describe it is the pixels on the screen seem stuck on the screen (see attached image). this is also causing the overall brightness to decrease a bunch, i’ve also had it just light up randomly back to how it should look sometimes, i cant tell what’s causing the issue. i could be completely stupid or entirely botched the ips screen installation, but if anyone could give me some insight that would be amazing. thanks in advance!

Where did you get this? It might be a good idea to talk to the seller. Did the console work fine before it was modded with the new screen? The issue almost makes me think there's an issue with a voltage regulator somewhere either in the GBA or in the screen.
