I'm wondering if reflections off the window are pulling the image to the left.
Could you try putting some pillows or hanging a heavy blanket over the window
just to see if things get better? Maybe room treatments are something to
consider. On the other hand, maybe what you are doing is exactly what a
balance control is for!? though positioning at 1:30 sounds like a little more than
just a little to the left. Another option might be toe-in but I think adjusting the
balance control is better than that and room treatments (see GIK) best of all.
By the way - channel imbalance - whatever the cause makes me crazy. So I feel
your "pain".
Good luck...
