1  Bitcoin / Mining support / Re: Troubleshooting and repair guide for AvalonMiner models 721, 741, 761, 821 & 841 on: May 15, 2018, 06:40:56 PM
I have been having the exact same issue and have had some success with taking off the back cover plate and using compressed air to clean dust off of the boards.

Thanks, another just dropped too. No word from Canaan yet, if anyone has seen this before please let me know. If I physically power cycle it will start mining again, sometimes for days before dropping out of CGMiner.
