So sorry for you man.
I bought a good sale of the umbrel home server for $325 bucks.
Maybe you have luck and can also find one. I use my raspberry now for webserver only.
Anyway good luck 🙏

Would love a Umbrel Home server. But a Little too expensive. Would rather just stack the sats for now.
Have bought a micro hdmi and borrowed a computer screen. So gonna tinker some more when to be certain of the problem.
