Hi all,

I'm having huge issues with our AVII 600 where all the channels are
unstable in regards of the tuning/matching. I was going to attach a video, but
it won't let me. I can send it to you if you want.

In tuning/match, signal goes from nice and stable to crazy jumps and interference
at random all the time. This happens:

on every probe (MAS, solution, imaging)
on any channel/preamp
Inside and outside the magnet
whatever amplifier is selectedwith any RF cable
No change after FULL REBOOT and cf

There' s nothing indicating a dead fuse, a dead fan, a dead board. No error
message. No red light in the front or in the back.

To make things more fun, the very same thing happened in June last year. The
last time, a 4-days vacation for the console did the trick. The intermittence
of the issue was worrying, but then it was all good until now. The instrument
worked fine until Monday for sure, but started showing issues on Tuesday.

Has anyone ever had similar issues? I’d appreciate your take on this..
