Bitcoin / Mining support / Re: Avalon 1246 acting strange HELP

on: January 02, 2022, 05:39:53 AM

Quote from: BitMaxz on January 01, 2022, 11:36:56 PM Those logs are abnormal and according to your statement, it seems that there are some damaged components. How did you clean them? If you just clean them with water and soap then you make your problem worst you should use liquid that is applicable only for Electronics like petrol or Lacquer flo thinner. I believe that there are some shorted components from your hashboard if you have known working hashboard you can compare the resistance between good and bad hashboard. Mostly dust and humidity can cause a short circuit that could lead to burnt parts. Try to focus on the parts where you see the sticky thing and dust compare them with known working hashboard. First of all thanks for the response. I know what you are saying and these are my thoughts as well. To clean some of the components I used contact cleaner which is used on circuits in order to avoid corrosion and shorting. Since I am a noob (frequently repaired pcs however) at Avalon Repairs, I attach another picture of the PSU. Could that also be a PSU issue? The unit itself turns on, I just want to be sure how to identify the source of the problem. I attach two pictures for your consideration. The PSU shows a red led light. Next logical step would be to: Check if voltage goes on the the hashboards from the PSU with a multimeter. Do you know where are the contacts the hashboard gets power from? Remove the heatsinks, clean everything with contact cleaner liquid and reapply thermal paste. Thanks.

Bitcoin / Mining support / Canaan Avalon A1246 Stopped working

on: January 01, 2022, 08:24:10 PM

Happy New Year to everybody! Wish you a lot of happiness, health and prosperity!

I have 2 x Avalon Miners A1246. They work in a really rough environment (I had no where else to put them) where it has a lot of dust / straw particles and lately due to winter a lot of humidity. One of them, after an Internet blackout failed to come back on. What I suspect happened is that that particular night had a lot of humidity, the miner did not have Internet connection and therefore it run cold (no hashing) for 3-4 hours. The fans were working therefore the humidity was entering normally. I cracked the miner open today and the hash boards are in a really bad condition. Dust everywhere, sticking around all the circuit components throughout the boards. I cleaned all the connections and components on the top of the hash board where the cable connects to the board but nothing changed. What do you suggest I do? My next option is to remove the heat sinks clean and put thermal paste again but I am not sure how I should preform this kind of cleaning. Would a contact cleaner spray be okay? I attach my error log for consideration. I will try and take pictures as well. I would appreciate if there is a way to contact you through a private message. If you prefer I can start a different thread. Thanks

Bitcoin / Mining support / Re: Avalon 1246 acting strange HELP

Stop using the prohashing and go to a proper Bitcoin pool!
Like eg. Kano.is, Viabtc or Slush

I feel like lots of these Avalon problem cases we forum members have tried to help at lately, are actually related to the user using a crap multi moving pool like prohashing, nicehash...

Why must you fist yourself in this ass like that?

Happy New Year! I wanted to contact you directly but did not find the way.

Let's give you something proper to check!

I have 2 x Avalon Miners A1246. They work in a really rough environment (I had no where else to put them) where it has a lot of dust / straw particles and lately due to winter a lot of humidity. One of them, after an Internet blackout failed to come back on. What I suspect happened is that that particular night had a lot of humidity, the miner did not have Internet connection and therefore it run cold (no hashing) for 3-4 hours. The fans were working therefore the humidity was entering normally. I cracked the miner open today and the hash boards are in a really bad condition. Dust everywhere, sticking around all the circuit components throughout the boards. I cleaned all the connections and components on the top of the hash board where the cable connects to the board but nothing changed. What do you suggest I do? My next option is to remove the heat sinks clean and put thermal paste again but I am not sure how I should preform this kind of cleaning. Would a contact cleaner spray be okay? I attach my error log for consideration. I will try and take pictures as well. I would appreciate if there is a way to contact you through a private message. If you prefer I can start a different thread. Thanks
