Im in Europe and im struggling a lot to repair one hashboard, this is so stupid that in a multi-million business like mining and multi-million enterprises like Bitmain dont have a european repair center or partner and if i want my hashboard repaired even inside warranty i need to send all the machine to them and pay transportation, WTF? I prefer to mine without one hashboard!
So i decided make this post, if there is no special repair center we need to create one, im sure people dont mind to pay to repair one hashboard or PSU if they can have one not official repair service better than the original.
Someone knows someone in europe specialist to make repairs or help to create national, european or world network website to support repairing mining hardware?
I agree, i'm pretty sure there is some guy in Europe though....You can check the chips resistance individually to find the faulty one BUT and i presume it could just be removed as i would of thought they are all in parallel.
Look for post on making probes to test, you can see the 5 test points on each chip BUT you need to make a set of 'needle' probes as it is so tight between the the sinks.
Or there is a tool on Ebay that tells you which one, but how you would remove or even replace one (kits also on Ebay) you would need specialist kit.
Good flux/solder flow etc.
Let us know how you get on mate.
