Ds turns on but shows Red Light on brightest settings/games.

I have a total of 3 systems with this issue. Two ds lites and one fat ds. All these consoles had the same repair which was the replacement of the f2 fuse. They used to not power on at all but now they do after the repair. However, now they constantly show a red light on the brightest settings or running games. They show a green light idling and on low brightness settings. The fat ds flickers back and forth from orange to green depending on how demanding the game is.
What I have tried:
Reflowing the fuse.
Trying several different batteries.
Continuity tested a few things near it or the f1 and L2 fuse (relatively new to this kind of testing).
Trying different motherboards and confirmed it's just these ones.
Fully charging batteries.
Any ideas? I can find absolutely nothing to help me with this.
