Soooo here my experience with the RMA.

First, if you don't run your machine in a perfect condition (Not like me cracking a window so the intake got fresh air), you might want to think 2 time before sending your machine back. BTW, my other machine was next to this one and it's still run rock solid. (1654gh) So I guess that was a bit of bad luck ...

So as I was using my SP20E close to a cracked windows and they found some corrosion near a capacitor. Also dust (because I didn't want to open it to void the warranty) and it's not under warranty because of the corrosion. Both ASIC 0 and 4 on each blade (which are the first one next to intake) are in bad shape.

Asking 200$ (105$ shipping and 95$ for the diagnose) for the exact same machine.

Asking 250$ per board to replace them plus the 200$ us.

Sooooo next time you run one of those close to a windows. You should keep it home I guess. Open it yourself, have a look or find a electronic specialist to have a look. It will save you time and you machine.

If I knew, I would simply disable the Asic and keep like this ...

but now for 200$ us ?

Not even sure it worth to get it back ...
