So, I was downloading pictures into my computer the other day, and I went to un-engage the cord, via clicking on the icon as instructed. It never said anything after a long wait, so I unplugged it, and then it gave me a warning that I could damage my camera.
Which is evidently what happened. Now I have grey and white stripes on my viewer and I can’t see the image of my potential photos.
If you haven’t found a reference to a reset button, you might try Mr Blue Sky’s suggestion in post #2 - remove the batteries, wait a few minutes, and put them back in.
