Has anyone had to do a warranty return/repair? I have a hashboard that doesn't show up anymore on the status page.

This is what happened: I was running Blissz and it was showing me inflated hashrates on chain0 and failing with xxxx's. I rebooted and changed frequencies/voltages but nothing seemed to help. I switched back to the stock firmware and after some trial and error I was able to get chain0 to run normally. It ran for a couple of days and then just disappeared from the status page. I saw in the kernel log that it shows chain0 as having an asic count of 0 instead of 60. Also, I tried switching out the cables connecting the chain with cables that are known to work, and changing the slot it is connected to. I saw Bitmain also recommends reflashing the stock firmware and letting it run for 20 minutes, so I tried that as well. None of that worked, so it would seem the board is dead.

I don't know if I need to post on their support forum first asking for help, or if I can go ahead and create a help ticket, disassemble the D3 (removing chain0) and package up the faulty hashboard. Anyone know what the standard procedure is?

Yes, I've had to ship back 5 hashboards so far. Don't listen to other posters saying it's worthless. If you're in the US the repair site is in California so shipping cost through fedex isn't bad. I've already received 1 board back and have 3 more on the way already. Average turn around time seems to be 2.5 to 3 weeks. If your board is dead you should absolutely open a ticket at support.bitmain.com and wait for a response. It cost me $9 in shipping costs for a single hashboard to be fully replaced. Bitmain then gave me a $9 coupon to use on their site. Get your board fixed or replaced, there's no reason not to.

Bitmain is terrible regarding communication. Their site says you have to ship the entire miner, the phone number for the California repair site doesn't work, creating a repair ticket asks for the tracking information (should you ship before opening the ticket? nonsense), other types of tickets don't have option to select warranty issue... The list goes on and on. Maybe they do good repairs but is hard as hell to get there. I opted for paid repair with bitmainwarranty.com, let's see how it works.
