I had a few lights not working traced the wires from the board to the light checked okay checked signal coming from the board did not have any signal, located the transistor for 3 of them which used the 2n560 transistor and one used the MCR 106 transistor, replaced All 4, the light that ran off of the MCR 106 started working the other three did not, I checked the transistor legs on the new ones and the bottom lug or the left if you're looking at it from the flat side with the Positive probe hook to it I got a reading with the negative Probe on the right outer leg nothing in the middle period on the existing ones on the board which are 2n560 the left lug looking at it from the flat side had the negative probe and the positive probe was on The Middle did not get any reading with the Probe on the right lug. So it seems that the new 2n560-730 has different input and output leg. Is that correct do they make more than one 2n560 is might be my issue?
