DNA board? Pm me and I can assist with a fix. It's possibly a bad solder joint that can be fixed easily if it's a DNA board.
So my bad luck continues! Last night my BB decided to pack up on me. The second I put the battery in it starts ramping up the wattage on my display, almost like I'm holding the up button. The button still clicks so I'm thinking it's in the electrics. I'm now down to an old school setup (that still works perfectly after two years minus the notorious Kangertech paint job - Why does everything I buy lately have a 4 month lifespan!!!!)...

On the plus side, for me the Subtank outshines anything I have in the Subtank!
