In Progress Node board repair

[cmrl9]

Not sussed those ones out yet, there's a bit of a long queue here -- been prioritising those that aren't mine

No worries

Well one of them probably doesn't have a fault I think it was the actual pins on the connector block, be interesting to know, (dont worry I don't care if it works fine )
The other acting as node 9 is definitely a cap issue not holding its charge to start the board I suspect, as it will work once machine on for a bit and a charge has been put through the cap, quick turn off and on again works perfect, until powered off for a bit.

So - Question. I have a faulty None 9 board somwehere for GB. My machine is fine - picked it up as a "faulty spare" just in case.
Is there any realistic chance of damage if i through it into mine for fault finding, at the very least to try to work out what the current status is before starting a repair?

Not impossible but minimal chance to cause any damage I would think unless the "faulty" symptoms include black smoke coming out of the machine.

You can do a standalone bench test by supplying the 48V rail and putting 9V or so across the VNB rail on the RJ45 connectors. If red & green lights come on, and the orange one flashes, the power is good and the MCU is alive. See post #34 in this thread on page 2.
