Take the battery and the lens out of the camera you just purchased. Put another lens on it, and reenter the battery, charge. If that doesn't work, do a factory reset. This procedure has worked for some Canon DSLRs. Maybe Sony Mirrorless? If none of these work, you'll have to send it in. Or try a different Brand SD card like San Disk, before doing that. SD cards are rather inexpensive today. Good luck.
Thank you for this suggestion. I did this and still have the "NO CARD" message.
