Cyber not striking / Transformer issue

I have this annoying cyber that's driving me nuts; it won't even attempt to strike. I've changed the lamp, psb, ignitor, even tried connecting a known good logic board with new 14pin to the psb, so see if that was it. I am getting 120v ac on when i meter the circuit leaving the psb. Does it (or should it) jump up when it tries to fire the lamp circuit (i'm metering pre-ignitor) -- and if so, what should it be? I didn't swap the ballest or cap since it hasn't even made the bulb strike, let along not douse. :aargh4: Any ideas what I'm missing?

Also, on another fixture, what does it mean when the green light on the psb is not lit? Usually fuses, but what if it's not that? ... Is that surely a transformer issue? I've always swapped the psb and it's usually solved the issue but this other fixture is just being difficult. I doubt its a 14 pin harness issue (as others light without that connected). Bad power2logic harness would cause a no-motor LED correct?

    [quote=stephenwyker;39316]I was under the impression that if the ballest was bad, the lamp would at least make the attempt to strike but just not stay lite. I checked the wires and they are good. PFC is fine (I swapped that later in the evening)

    My hunch from you description is that it is the ballast.

    [quote=stephenwyker;39316]As for the LEDS, I have one PSB that is missing the green LED. Checked all the fuses.

    I would say with 99% certainty that it is a bad transformer in this case.

    [quote=stephenwyker;39316]On another, it's the motor LED on the logic board. The logic board issue, I swapped the 14 pin cable, and that did not make a difference. I just sent out another batch of pcbs to get repaired, so I don't have any more spares at the moment. Just thought I was missing something.

    Have you tried swapping this logic board into another fixture? If the problem follows the board you know that this is where the issue lies.

    It it does not, it could possibly be the PSB or the transformer. If you have all good voltage indicators on the PSB it is not the transformer.

    Make sense?
