I could see things not getting updated being a sd card issue, if the pattern of LEDs is the same on the dead board as the others then you don't have a blown chip, normally there drastically different or not at all, you said green/red LEDs so I am guessing the boards are green, check cables , swap two of them and see if the dead board moves or stays the same, if it moves then maybe a bad cable if the same then might be a messed up board, most trouble shooting steps at this point are very advanced, requires probing stuff and such. I don't know if I would buy a new board really the cost vs/ the payback is going to be a bit off .

Ok, so after some troubleshooting with no luck, I decided to let it be for a few days. Suddenly tonight I had another board basically die. This has to be a power supply issue, right? Should I try switching out the 6+2 pin PCI cables? Or switching around where they're plugged in? PSU is fully modular, so I have a few open plugs to try, but I'd imagine if one part of the power rail fails, it all does... I'm starting to get really worried that I dropped over $900 on a rig that is just falling apart, and then another $280 for a PSU that I got no reimbursement for from Zoomhash, but I'm holding out hope that it's just the PSU. Is there a way I can test the output of the PSU? Having 2 boards die off of a 1300W gold rated output shouldn't happen. Hoping for a very fast response before I throw this thing off of a cliff.

your case sound very similar to mine.

My A2 had 5 boards, one by one the boards failed, and now I only have 2 boards working.
I have turned off the A2 - 110mh before 44mh now = waste of electricity.
I wrote to Innosilicon and they dont do returns...
But online sellers in Aliexpress selling 136$ per board - see my earlier post

Can your lasting 2 boards be installed into an 88Mh setup with the 8 chip boards? If so, what do you want for the 2 that are working?

I am not sure if can be refitted into a 88MH machine.... technically I dont think any issues... this A2 came with 5 board for 110MH.
One of nerd friends is working on the A2 now and I hope he could make it work again - so I will hang on to it for little longer.
