From a hardware standpoint, I think if leaving it running makes it fail from working it might be the internal wiring of the board so it might be worth replacing. There might be tech support with bitmain or on blogs you can check for this sort of information though too to see if there is an easier fix.
yes i got the option to send it back for reparation but i wanted to be sure its really broken...
flashing the miner may help ?

im oscar and once again thanks in advance for you help.
i recently got an antminer l3+
since the moment i put it on line hashboard n1 and n4 was not detected
then once i reset it all 4 hash boards went online.
after few minutes  n1 vanished and the n4  first was working fine and after a while was showing faulty chips... first 1 then few and then all untill the hash rate of the whole  board was 0.
yesterday after some strange self rebooring  n4 hash board came on line and all the chip are fine and now is already 1 day hashing full power.
any advice ??
should i change the n1 card ?
i already switched all wire around and its not the wire but the card i think.
whats your advice ?

Have you installed firmware from other sources than Bitmain recently?

Or maybe your PC or the device you currently use to change the pool is infected so try to change the pool on other device

If the issue still the same try to flash the miner through SD card flashing.
You can follow this guide below on how to flash the miner through an SD card.

- https://support.bitmain.com/hc/en-us/articles/115000216034-L3-L3-and-L3-Control-Board-Program-Recovery

For the SD card firmware, you can download it from here https://service.bitmain.com/support/download?product=Flashing%20SD%20card%20with%20image

Once successfully flash it again through WebGUI on other devices just download the firmware from Bitmain.
Then test again if it solves your issue.


thanks man
after many hours the miner still connected like before .
but i still dont understand how my mac could have been hacked.....
