Hi all, I hope this is the right place to ask. I just got a pair of Genelec 1030As and need some advice.

Background

The two speakers had different volume levels, so I tried to match them.
While the right speaker was powered on, I turned the input sensitivity pot on the rear panel with a (probably metal) screwdriver.
I heard a dull thump, and since then almost nothing comes out.

Current symptoms

Right speaker: almost no sound. Only when I turn the volume way up, I can faintly hear the tweeter. The woofer seems silent.
Left speaker: works normally.
The amp still seems to be getting power. [The ON light is on / no burning smell / no hum, adjust to what you see.]

What I've checked

Questions

Could the screwdriver have shorted something on the board (pot, bass amp, an internal fuse)?
Is there a known weak spot on the 1030A that fails like this?
Is this a reasonable repair for a service shop, and what should I expect cost-wise?

I've powered it off and unplugged it. Any advice is very welcome. Thanks!
