Quoted from Roostking:Update, Ive actually had this problem 5 times now. I didnt pay attention to the fix, since I only had it once by then. I have more time under the hood, so time to figure this out.
My first blown F7 this morning. My PREM was manufactured Aug 22, 2018. Everything looks fine on my MAG board visually..
Any update on what you found out ?
