Yaesu FT2900R too loud after MARS modification

I did an extended TX mod to my Yaesu FT2900R following this link:

And after I did a computer reset I now have the audio at what appears to be almost full blast and it will not turn down. Other than that the radio seems to operate fine, just that volume is now close to 100% and does not really change with the volume knob.

I did the mod with one of my sons, so I was not 100% in control but he did not appear to make any mistakes. Afterwards I've gone over the board with a magnifying glass and an alcohol Q-tip a couple of times, checked all the connections, etc etc. And yes, I do have auth. to transmit out of band. Ironic part is I wasn't really planning on doing it with this radio, but thought it would be fun to do with my son so now he'll probably remember this forever.....

Anyway, if anyone has a suggestion on a direction to proceed I'd appreciate it. About the only thing I can think of now is if we damaged the volume pot pulling the knob off, but don't really think so. After a few more ldeas I'll probably resolder the jumper pad and see what happens but don't know if that is truly related or not.
