So I ran through Kites set up guide, everything checked out fine. Powered on, charges, LCD working, etc.
However, after assembling my gameboy it will not turn on. It does power on if I hit the power test button that's soldered onto the board. So this leads me to believe that something is either wrong with the add on board or the power switch board. All were functioning properly before I assembled the gameboy but I cannot spot any noticeable issues with anything. Nothing looks bad on the jst female for the USB board, or the power switch board..
The only thing I can spot is that the ribbon cable connecting the two seems to be crimped a bit from installing. This doesnt seem like it should be an issue but just to test it I pulled it out slight to get a connection on the area of the pins that weren't crimped but still nothing. I taped off anything that would cause a short prior to assembly, so I'm at a loss...anyone have any ideas I can test out to resolve the issue? I've been super discouraged trying to complete these builds. Something went wrong with my CS and now I can't figure out this CSL

Thanks in advance for any help possible.
