I have an R4 and 3 PCI connectors melted into the power ports.
Would it be worthwhile to send to Bitmain, solder myself, or look for someone in the USA to do it cheap?
If you know of any services in usa familiar I'd like to know.
I have an acquaintance that suffered the same, and he soldered himself. For Bitmain the R4 is no more, i don't know what would happen if you ship it to them, but maybe the American branch could repair it, no idea.
NotFuzzyWarm might be into something, as i have never unplugged those from my R4 for the last couple of years and its doing fine.
