Does anyone have data on repairing these LED shop lights? 120 LED's with driver PC Board (see photo). Driver board contains 2 xfmrs, Power semi.,FWB rectifier, many other comps...operation is unknown. Most components test good. No burned areas. I'm sure these LED's are running some PWM regime...but what frequency and duty cycle, I don't know? Any help would be appreciated.View attachment 159175 View attachment 159176 View attachment 159178
