Well, I think I've got another case of blown FB24 and FB23. Modded 10 pods last night and one refused to hash although it was recognized by cpuminer. Opened it up and here is what I saw


I also noticed some bubbling on the centre chip and brown residue on the thermal pad.
I'm guessing the chip is gone, what are the odds the rest will work if I replace the beads? Anything I can check to confirm? Should I avoid using that barrel plug? It was working fine before the mod.  I've got a multimeter and am not afraid to use it. Thanks in advance!
