Why won't my SD card go all the way down? - Sony Alpha ILCE-6000 - iFixit
My SD slot on my Sony A6000 will not go all the way down. It only will go about half way down in the SD slot. There is nothing in the slot that I can see. I read where a part of the SD card may have fallen in the slot but I can't see that. Can you tell me how to repair this issue? - Sony Alpha ILCE-6000
