Hi Prasimix, further to posts 601 - 602 a week or so ago, in the (EEZ Bench Box 3 - sequel to H24005) topic, my BB3 with the notorious green board is still causing me serious problems.
It still will not always power on correctly, sometimes showing a black screen with standby light on, power cycling ususally corrects this, but far more seriously it resets completely and randomly with no input from me. By this I mean it can be just turned on doing nothing but with the outputs turned on, not connected, I will hear a beep and when I look across the workshop the BB3 has reset, I see the ethernet symbol flash as it reconnects and all outputs are now off.
This is really causing me doubts about the useability of this power supply, certainly for long term tests and analysis.
PLease could you offer any help or, hopefully, a solution.
Thank you and regards Mike

Hi again, just look what it is doing right now :-//

Ok, don't know how you ended up reporting this issue here, but never mind. It's highly likely that your MCU module is in trouble (a green version again that comes from Poland). If you have any artifacts on the screen probably there is some soldering issue with SDRAM or STM32F7 MCU itself. Please contact me on PM or info@envox.eu to continue with discussion.
Mike G:
I reported this matter here because in post 606 on the (EEZ Bench Box 3 - sequel to H24005) topic you asked me and any others to report problems on this topic page to enable you to build up evidence, if I misunderstood then I apologise.
I will contact you in private later today.
Mike

It was this #606 and you kept posting in the right place, so it confused me how we ended up here, but it doesn’t matter. You have my PM in your inbox.
