My SP has the screen white but plays games fine.
After turning on the GBA, the screen goes blank but the sounds play. Games load and button input with the game works fine, so the game appears to run fine. The only problem is the video output.
I swapped the screen for another one that I know works perfectly and the GBA shows the same issue no matter the screen, so it must be a damaged connector or something with the motherboard.
Where should I start?
