I just got a used A2 Terminator a couple days ago. It had been running just fine until I noticed that my hashrate dropped after about a day of mining. Found out that one of the blades had failed somehow. I tried rebooting, resetting, and all that stuff, but the one blade is just no longer detected. When I boot the unit, the top 4 LEDs (LED-UA1, LED-UA2, LED-UA3, LED-UA4) on this problematic blade blink but the other 4 don't (LED-UB1, LED-UB2...). These 4 LEDs will just continue to blink while all the other blades begin hashing.
Anyone ever encountered this and find a fix for it? Here's a picture of the LEDs on the blade.
