Antminer L3+ showing just 3 hashboards instead of 4

[theghost1980]

Hi there. Since yesterday I can see my panel as the following:


You can notice only 3 hashing boards working just fine. The #1 is missing. There is no xxxxxx or -------- or something else warning or saying something else.

I have tried reseting the miner to factory settings. Switching off/on several times. Changing the PSU unit. Testing the cables on the PSU (all are good 12.3 V+ each). So far I have no more ideas about what to do or try. Since yesterday I'm still waiting for technical support but they may be celebrating another Chinese year :S

Any help it would be very appreciated. Thanks for your time.

Did you tried to switch the cables from control board to hashing blades ?

Create a repair ticket  , your L3+ should be under warranty

Thanks for answer. In deed it is damaged. I have tried changing the data cables of each hash board and the #1 is totally missing. So I'll send it for repair. It is pretty new but I asume that it was my responsibility. Basically I left another person "taking care of the miners" also the ventilation duct it had a curve (about 45 degrees) and I've learnt a big lesson it should be straight :S

Thanks man!

How long did it take to get your board repaired?  I got a late sept batch and after a few hours the board disappeared.
