I received the phoenix 12/800 from my customer, it's dead. Looks like the microcontroller receives the power, but that's it. Main 12V power rail passes on through via's power to the MOSFETs, but there's no even LED on when you plug in 12V.
Is there a way to make sure that the microcontroller is faulty? Or, any other test that I can make to not send it under the warranty and fix it on my own? I fix electronics for 20+ years and even have 5 star rating on google ;) in my area.
Please help me to fix it, let's fight for the right to repair by fixing all of them :). We waste per year thousands of tonnes of e-waste here in the UK, and that reason should give us a reason to help each other though.
Thank you.
