I received my P3 last week and really enjoyed the first hour... until black screen during boots... I have replaced all material and at the end, only the riser was remaining ! I have removed this one with a new setup and it works perfectly fine... I'm working in the industry as you and I have to admit that risk assessment and product management is a disaster here when you see the first RMA !
I already sent a mail last week and I'd like to get a quick feedback since you are not a start-up...
Thanks in advance,
