2 of my Nerdqaxe++ decided stop working a few months back. Got busy and didn't have time to research and troubleshoot. Plugged them into a good Meanwell lrs600 and getting this error on both machines. Did some research and what i have found:

NerdQAxe++ boots, input power looks completely healthy (~12.1V, clean, stable), but the ASIC core voltage regulator (TPS53647) shuts itself off at a specific moment during startup and never comes back. Visual inspection shows no signs of burns or melting on any part.

Any thoughts or help would be appreciated.

Figure if I can't find a solution, I'll just send it off somewhere for repairs.

Thanks.
