I just put together a DNA 200 mod, The mod seemed to function properly, buttons work, fires attys, vapes fine. However as soon as I tried to plug it into my PC this component heats up. It actually started to melt the Display tray I had installed into the mod. If I plug into a USB power adaptor, the board does not charge either. Just strikes me as odd that as soon as it connects to the computer that it does this. I've circled the component that heats up dangerously. The fuse seems fine, I don't see any broken resistors or anything of the sort. Is this a bad board?
