Yes of course I disconnected the PWM wire from the logic board. Both where disconnected. When I put high the ON/OFF line it turns on ok (PWM disconnected as well). When I disconnect the logic board and pass PWM from the tester to the inverter board and rise the ON/OFF line to 2.8v it turns on but goes flickering (no idea on frequency coming from the tester). I was thinking maybe generate square wave from the tester at that specific frequency (200 - 300 Hz) and see what happens. Should be sort like a 50% duty cycle signal.
