Hi I had an issue with my camera’s SD card slot and I disassembled to look why it wasn’t reading SD cards and found an issue and I think I fixed it, but when I assembled it it won’t turn on now. Do you have any advice on figuring out what is causing it to not turn on? I checked all flex cables and they seem to be connected. Any help is appreciated!
