Sorry to hear this.
Worry not of flames .. for any reason Here .. even if you did test with a ~choke~ mmMsi board. hahhahaa
Actually that was quick think'n .. and done.
Now .. get your RMA # and PM @cl-Albert to have him get eyes on it a.s.a.p.
To be honest and straight up with you though .. chances are slim to none that it will be New.~sigh~but ...
There is always an off chance that it might be .. if they can't repair yours they send a ~shudder~ refurb.
Now before your knee jerks up and busts your nose .. lol .. in my view they are better than new ..
The one you took out of the box that Won't work was New.
This means the refurb was on the tech's bench and is 100% certified to be running in spec.
Either way .. I hope the experience ends in great Joy .. and that starts by getting @cl-Albert involved.
Please keep us posted on the progress ..
Let the Adventure called RMA begin. [and end quickly / joyfully].c.
