Go Pro Hero 3 Black, had large impact, now will not function?

Hi,

I was using my GoPro Hero 3+ (Black edition) without the poly-carbonate cover. It took a fall from about 10 metres. When I recovered it, the front LCD screen was cracked and the micro SD card had come out.

When I tried to turn it on it beep like normal, when I put the micro SD card back in I noticed the slot was extremely hot to touch (burning hot), then the GoPro turn off with no noise.

I tried plugging the GoPro into my laptop to check the micro SD card but the GoPro would not stay on after putting the micro SD card in, so I can't even use it as a card reader.

GoPro 3+ (Black edition) is not a cheap camera and I have only had it for about 4 months.

Has anyone had a total failure of there GoPro and was able to get it back to a working state?

Thanking everyone in advance

Lee
