Sure, draw the circuit with the (des)integrated circuit on a sheet
of paper and upload it. There can't be much more than a handful of
components connected to the unknown circuit.
And put the board on a scanner, that's always better than a fuzzy
picture from a camera.
yes, the Q mean transistor, sure, there are other int he board. I've measured it, It is a double NPN transisotr, so problem is solved now. Thanks again.
