axis T90A power supply schematic needed

Recommended Posts

Does anyone have a more detailed schematic so that I can troubleshoot this without having to trace out the circuit by hand?

Thanks in advance.

Notes: I get no light, the LED lamps were ok tested with an external lab PS.  The light sensor is ok.  The FET (p-ch) appears not shorted (gate not being pulleed low so it is not turning on and regulating).  The internal 15V ps is ok.
