Next I would put a volt meter on those transistors, looking at everything it must be setup for 5 channels. On each of those transistors one of the pins must have a PWM signal going to them. If you put the GND probe from meter on the common GND and then check the 3 pins on the transistor. Check with light full power and then check with light at 50% power. One of those should be different when light level is changed. And yes good luck checking those voltages with the module plugged in. :)
