Bias question on a Rogue Cronus Magnum 2

I checked the bias the other day, following the instructions from the manual.

Three tubes went perfectly.

On one, however, when I flipped the bias switch the meter jumped up like it was supposed to. I went to adjust it like the other three, but when I used the tool to turn the tiny screw...the meter didn't move at all. The meter is supposed to move when I adjust the screw. When I flipped the switch back the other way the meter went to zero.

I tried it a couple times and same thing on that one tube. I could turn the screw all I wanted back and forth, but the meter didn't move. Audio sounds fine, so I'm not sure whats going on. Is it the fuse? Is that screw stripped?

Thanks in advance for any advice!

Paul
