Some have problems with accidentally firing fire button with Isticks. I have opposite fault: it wont fire at all. I just dismantled the device for pieces and cleaned both connection surfaces (button and connect studs) with isopropanol and reassembled my Istick. No help :/ All wires seems to be where they should be and everything seems to be clean and in order (don't understand enough how to investigate circuit board itself). Should I try to add some more parts (what material, some metal??) between the fire button pin and circuit board pin be a solution? Any advice what to try? Similar problems others?
