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.

I had this once on a 88MHs A2 Terminator but it went away with a power cycle.
You should first check the power and USB connectors going to the problematic blade, I could well imagine that they became lose in transport or in the first hours of operation from vibrations. Also check if the problematic blade gets warm (= has power).
Checking the output of lsusb and dmesg in the RPi might give you further hints on whats wrong.

I can tell you that you more than likely have a blown ASIC on the board, I have see this LED combination on the old blue boards when you have a failed ASIC. I have repaired a few of these.

Right, like the threadstarter i also have blue boards.
One of the six single leds round the board is off aswell - so one of the asics should be defective.

If anyone has some spareboards to sell, please contact me via pn.

thanks,
Andy
