No output from Multiplus and only a brief flickering orange LED

I'm now on my second Multiplus 1200 with this issue:

Unit works fine for some time (first unit a few weeks, second unit a few minutes) and then when trying to turn on there is only a brief flash of the orange charging LED and no signs of life.

There is definitely voltage at the input terminals, there are no external fuses blown, there are no additional connections (remotes etc) and I haven't touched any settings from factory defaults. I have tried with AC load, no load and even no connections.

I can find no description of this problem from Victron but there are another two people who experienced the same recently:

https://community.victronenergy.com/questions/206967/multiplus-12120050-not-turning-on-not-charging-not.html

Does anyone have any more suggestions I can try to troubleshoot this before I am forced to start another return? My installation is totally standard and this problem happens when only the 12V positive and negative cables are connected so not sure what else to try.

What battery are you using?

A little more info on your components, firmware and setup would also help.

The one topic you reference was answered by the user and identified a bad RJ45 cable, so that one does not seem to be related.

Sorry for the obvious question but:

Are you switching to ON not to CHR (charger-only)?

There was a similar issue in another thread
The dealer may have upgraded the firmware.
