Topic: Avalon A1246 Repair Manual (Read 196 times)

Hello BitMaxz... First of all, thanks for your reply. To answer your question about flashing, I'll give you more details regarding the malfunction evolution.

One day, I was looking at my pool app and saw that this machine drastically dropped its hashing. Since conditions where I have it aren't the best, I decided to do an open ventilation check to figure out what was happening: The miner was rebooting after 5 min running, and the hashing went up at first and then came down to settle at 10th. Before reboot, the red led light started blinking and the SYSTEMSTATUS showed the 'Out Over Heat' msg. Despite of this, the Overview window wasn't showing me any heat problems (fans nor hashboards).

So, I started looking for a solution and found a similar issue in the forum threads (https://bitcointalksearch.org/topic/avalon-1246-acting-strange-help-5379337). That's why I decided to take out the heatsinks and see more closely. Efectively, paste was all dryed up and opted for cleaning and repasting. After that, I tried once again but nothing changed.

Accordingly, I decided to do the flashing to discard software issues and ran the miner on High Performance Mode first. After 7-10 min, hashboards H0 and H1 (H2 was 20C cooler) were giving abnormal temp values, going past 90C, triggering the alarm. Then I changed the configuration to Normal Mode, to see the difference.

Although the machine settled at 50th (better than nothing), the 'Out Over Heat' msg disappeared, and I didn't see any hardware issues, I still can't figure out the high temps of H0 and H1 shown in the log I posted. I'll check again the paste job as your're suggesting and keep updating any progress.

Hello HagssFIN... Thanks for the comment. I'll review the info and the manual.

Hi there,
you can check my rather old Avalon troubleshooting guide if it helps a little with the Cgminer API log codes (link is in my signature).

Also found this info about Avalon 10 series.
After the 10 series it seems that they have stopped updating their public git at the Github.
https://github.com/Canaan-Creative/avalon10-docs/blob/master/Universal%20API/Avalon%20A10%20API%20manual-EN.md

edit:
I also found the Avalon 1246 manual at Zeusbtc. They have archived lots of documentation which can be useful.
https://www.zeusbtc.com/Support-Manuals.asp

Based in your logs, it exceeds the overtemperature limit above 85c look at the TMAX and MTmax its more than 85c the problem is why did you flash it with the latest firmware if the old firmware is working fine.

I think better check carefully those overheating ASICs focus on these logs PVT_T0, PVT_T1, and PVT_T2 look for those asics with high temp disassemble the unit again and make sure the thermal paste is not messy.

Hello... since you've been addressing Avalon 1246's issues, I would like some advice/input about my case. (Background) I have a 3 year old machine that was working fine until a week ago, when it started to show hashboard overheating. From then, I've replaced the thermal paste and upgraded the firmware.
 
After flashing today, I left the asic to run for more than an hour on normal mode (in high performance hashboards overheat) and retrieved the log before shutdown:

I'm not exactly tech savy regarding asics, but I have a basic understanding of how to handle common issues. Regardless, I would appreciate some insight about the log parameters and what is really happening...

Currently, no one yet sharing a repair manual for this unit.
If you want to learn how to repair them maybe this link below will give you some idea of how to repair the A1246 hashboard.

Why not discuss here what exactly your miner issue is?

Hi everyone, does anyone have any repair instructions or info for the Avalon A1246 hash board? I was looking for an introduction, but I only found its installation manual, nothing to do with hash board repairs
