Hi,
I have installed the Hispeedido Q10 AMOLED in a custom shell. Before the transfer of my GBC board to the new case/screen, it was loading games fine. Only the sound was broken, so I changed the speeker and the capacitor C38. The sound was then working fine.
After installing the board in the customer case and AMOLED, the system powers on fine, but it does not boot any games. I only get a black bar where the Nintendo logo should appear.
Switching the board back to the original screen everything is working fine again, so I do not think that the board or gamecard slot is broken.
Cartridge slot and power switch have both been cleaned as well. Still I cannot get the system to load games when AMOLED is attached. Do you have any idea what the issue might be?
