Black screen / delay on startup with the FunnyPlaying IPS kit (random)
So I’m having a rather unique issue with my GBA SP. I installed the FunnyPlaying IPS V2 kit in a custom shell, and even after taking it all apart twice my problem persists.
Upon startup, I get a black screen. The sound works, the game works, but the screen will be black - sometimes it comes on after just a second, sometimes it will take 30+ seconds for the screen to kick on. Other times, there is no delay and it will start right up! Everything else works fine, and once the screen is on, my game works and plays great.
I have checked all connections multiple times, the ribbon cable is definitely seated properly. The only things I can imagine left would be my soldering on the brightness control wire or perhaps the foam insert? This is happening completely randomly, no variables are changing in between startups yet it is completely inconsistent. If anybody has any wisdom for me it would be highly appreciated!
