will not accept an SD card or allow me to format it
I can insert a memory card but it shows "Memory card is write protected" When going to menu all is in gray, no function. I tried many cards it's the same.
On the left side of all full size SD cards, there is a yellow slider. Sliding it down locks the card as shown by the camera. Sometimes, the slider can get loose and slide down when you insert it into your camera. You must either replace the card, or a simple fix that only requires a piece of tape. Take a small piece of tape and wrap it around the slider while in the up (unlocked) position, making sure it doesn't cover any of the copper pins. All fixed! Hope this helps!
Some cameras have a limit on the size of card that it will read, try a smaller one 4 gb or less.
