Hi i have an LED garage light. It has two bulbs/strips of led lights in it. One of the bulbs is flashing. I dissassembled the light to get to the LED driver board.
i am enclosing pictures.
given that one works and the other does not (ie...flashing) i thought i should be able to fix this.....or at least determine what is wrong.
the led driver board basically had "two" drivers on the same board. I began probing using my multimeter trying to find differences between the two. Now there may be diff i did not find but one difference i did find was diode6 (D6).
for the side that worked i measured diode D6 (RS1M...i think this is part number) using diode check and it measure ~0.5V. I measured D6 on the side that does not work and two things: (1) i did not hear the beep (2) the voltage measured was ~ 1.3V.
I removed D6 from the bad side thinking this is the bad part......i measured D6 removed form the PCB board and it measured good....or at least same as D6 onthe good side ~ 0.5V.
I then measured across where D6 was on the bad side (ie...with D6 removed from pcb board) and measured the exact same voltage of ~ 1.3V.
Now i am not an expert but does this mean that the D6 ont he bad side was shorted? If so how do i find the shorted part........if not any ideas on how to proceed from here
