I have a D50 that is about 2 mos. old. I used the camera about a week ago with no problems whatsoever. I took the camera out to use yesterday and now it won't read any of my three SD cards. The green light doesn't even light up when a card is inserted. Also, the color LCD screen on the back does not come on at all, no matter what button is pushed. The battery indicator on the top flashes indicating that a battery is not inserted, even though it's fully charged and inserted properly into the battery compartment. The viewfinder also indicates that no SD card is in place, even though one is inserted.

Anyone experience this problem? Is there anything I can do, or does this need to be sent in for repairs?
