As a student interested in electronics I have picked up a non working Airblade AB03, plug it in, insert hands, nothing happens.
Took the cover off, started probing the PCB, at first glance, the power regulators work fine, the sensor output some kind of waveform on the oscilloscope, the ribbon cable to the motor assembly is carrying some king of signal too with some delays after inserting hands it seems .
So because I saw nothing obvious, I went looking for a problem on the motor assembly but turns out to be harder to access then I thought.
So before I go any further, any one of you have experience with the general troubleshooting of the AB03? What I should be looking for etc?
I am planning on updating the thread as I go with pictures and oscilloscope reading if needed.
Thank you in advance.
