Yes, I plugged in all the wires. I've also tried two different USB cables. I can try some others, but I'm concerned that neither board will power up on it's own without USB. I check the cell voltage with my multimeter, and each one is over 3.7v so they should be charged enough to turn on the DNA. I do have a dedicated LiPo charger coming from Amazon tomorrow so I can verify the packs are charged, but I don't know what else to do. Would sitting around unused for almost two years cause something on the board to fail? What about the fuse I keep reading about? How to tell if that is tripped? Visually they look ok...

I've got two DNA200 boards, and I can't get either one to work. They both were in working mods bought around 2-3 years ago. One was in a Hcigar VT200 and it stopped charging via USB, so when the battery died it just sat on the shelf. I planned to buy a replacement battery for it but never got around because I had other mods to use. The other is from a Wismec Reuleaux (1st release) and on that one, the battery sled cracked and again I plnned to rebuild it, but never got around to it. Now, I'm down to one mod (Kanger Drip Box) and I've been having issues with it, so I thought it was time to rebuild my DNA devices because I do miss the vape quality they gave. However, after buying a pair of new LiPo packs, I cannot get either board to power up or be detected by my PC/Escribe. What are some initial troubleshooting steps I should do? I find it odd that neither board will respond or power up. I had wanted to get one of these working before I leave in a Christmas trip, but I don't see that happening now :(
