It would seem to indicate it's not taking any appreciable power, if any.So would you say that when BucksLad reports "approximately 12V and 6V" that this is indicating a problem or not?
Going by the inductor count there there are several local SMPSUs on main PCB and it's entirely possible one may be critical to the unit's operation. Of course it may not be a power issue at all but the usual fault-finding procedure on a bit of kit like this is to check power rails first.
Ah, just realised the ambiguity in what I wrote. I meant how I'd tackle it using what I have. A 'scope is vital - there's very little you can do on a unit like this without one.Are you suggesting this is the way forward or would it be better to suggest something he is likely to be able to manage?
