I had my A74 repaired for slot failure, here are the details. It was only a couple months old when it happened, the SD card in slot 1 (the only one I had been using) was in the permanent eject position and would not allow a card to be inserted. I took to my excellent local repair shop, Tucson Camera Repair. He could not fix it and said he would have to send it in to the only authorized Sony repair facility, which he offered to do on my behalf. The parts were backordered and it took about six weeks to get repaired. It was fixed under warranty, but I had to pay the shipping cost to my local repair shop. I have since been using slot 2, the single slot, since reports on this forum suggest slot 1 (the dual slot) is more prone to failure.
