Anyone had a controller go bad?

Went out to the mine one day after a a4+ showed offline. Strong smell of electrical fire in the mine. Traced it back to the offline a4+

First few boot attempts the smell was VERY strong. My clothes even smelled like it after returning home. Miner starts to boot. Lights on all 4 boards go off and the fault light flashes. Miner never requests an ip address. Will not boot with any boards attached. After a few attempts the smell went away.

Yesterday during troubleshooting it randomly decided to assign itself an ip address outside of my subnet (10.58.133.0/24 when my subnet is 192.168.1.0/24). Grabbed an old router and configured it to that subnet and no luck. It wouldn't even request or assign itself an ip this time.

Innosilicon keeps telling to to update the firmware via the management console. Despite my repeated emails telling them I cannot access it.

Holy shit. Shocked

Innosilicon is one big joke. I must've have extremely good luck with Inno-lottery but this kind of shit keeps coming up. Tongue

Sounds like some component(s) have released their magic smoke (and even by 2018 there's no cure for that Tongue

). It could be something simple like a resistor or capacitor blown up since you had some luck at somehow get it to "work" for a while. Though this is something you should never be worried about. This is unbeliveable.
I would personally try to fix the board or source a new one rather than deal with Innosilicon with their superior guarantee etc.

Nevertheless, I wouldn't try to boot the thing up again until the problem is located and fixed. It could do a lot more harm than what you already have. Sad

In their defense they have been good at responding quickly. It's just they are having trouble understanding me.

I have avoided opening the miner to find the burned component out of fear of them voiding the warranty but I'm going to open it next visit and figure it out.
