Most lasers are adjustable. Not sure where the pot(s) is(are) on a Bose device, but it will be there. Usually they are on the back of the device. I would state that probably 80% of lasers that are replaced could have been adjusted and been just fine.

Best of luck with it.

No highs? No lows? Must be Bose!
How do I identify these pots and how do I determine which one(s) to
turn?

The pots that should be adjusted are on the board NOT the optics assembly. The optics have an adjustment for laser power that rarely resolves any problem. The should be focus and tracking adjustments on the board. You need to see a trace on a scope though to properly "align" the optics.
