[FTC]: Beacon problems

[kgzak]

We are having issues with our beacons. At the beginning of the year we bought a set of four beacons and two of them have failed.

One of them no longer powers up at all. Every once in a while you can see the LEDs flash for a brief moment and then nothing. We tried re flashing the firmware but it won't accept it

The other one has the problem where one of the buttons on the field side works but the other one does nothing. The randomizer button also acts as a field side button but its always the same side as the field side button that does work. After a certain amount of time it will also just change automatically. We have checked that there are no shorts and still get the weird behavior We have tried refreshing this one and it says it accepted the firmware but it still operates wrong.

We came up with the conclusion that static might be the cause of this because last night I touched a button and felt a static shock and the light on that side turned yellow. We disconnected power and plugged it back in and it started working again. Before this we were wondering if the way we were powering them was causing the issue but I don't believe it would. We currently power them with a 9 volt power supply so we don't have to waste batteries.

Has anyone seen this before? Is there any fix?

Thanks
