Oki Doki - Apoloiges for the delayed response, but i needed some help to test this stuff. Here is what i have:
-No voltage on any inductors
Put some power through pins 74,72,70 and tried to trace through the board - i believe there could be a dead TVS diode (The one marked in red - TVS?)
I get continuity from power pins to one side of the diode, and i can get continuity from the other side of the diode to the sms6741 pins indicated in the image, but nothing across the diode. Is this normal? Am i correct to think that the diode is dead and to replace?
Also, if it sounds like i have no idea what im talking about - its because i'm really a bit out of my depth so the more information you could provide the better. Thanks a heap, really appreciate it!!
