When the camera shows"nocard", it means that the camera has not detected the correct memory card (SD card or other storage media). This can be caused by several reasons: memory card not inserted, memory card corruption, memory card format is not supported, etc.
To solve this problem, we can try the following solutions:
1.Confirm that the memory card is inserted correctly: First, make sure that the memory card is fully inserted into the camera's card slot and that it is inserted in the correct direction. Sometimes, the memory card may be loose or inserted improperly, which causes the camera to not recognize the memory card.
2.Check if the memory card is corrupted: You can try inserting the memory card into another device, such as a computer or other camera, to verify that the memory card is working properly. If the memory card is not working properly on other devices as well, then there may be a problem with the memory card itself and you can consider replacing the memory card.
3.Format the memory card: In some cases, the memory card may need to be reformatted to work properly in the camera. Note, before formatting the memory card, make sure to back up all the important data in the memory card as formatting will erase everything on the memory card. Try formatting the memory card via the camera menu or by connecting the camera to your computer.
4.Confirm if the camera supports memory card formats: Check the camera's user manual or the manufacturer's official ** to confirm the type and capacity range of memory cards supported by the camera. Sometimes, the camera may not support certain memory cards, memory card capacities, or memory cards of a particular format.
5.Clean the memory card slot: Sometimes the memory card slot may have dust or dirt that causes poor contact. Use a tool such as an air canister or cotton swab to gently clean the memory card slot.
