Yamaha ax 500 potentiometer replacement

[kapuchahaha]

Hello, The pot for the 'treble' knob doesn't seem to work. I tried spraying it with deoxit but it didn't have any effect. When I move the knob I can't hear any effect or even a crackling sound. My question is whether anyone knows the exact parameters of this potentiometer, the model or has a photo where I can see it in its entirety. Thanks in advance for aby help

Check where the pot connects to the circuit board for cold solder joints. Yamaha has a problem with this.

Thanks for the help. Now that I've looked, it does seem like there are cold solder joints, so I'll try to fix them. By the way, do you know the parameters of this potentiometer? Do You think something like that from the picture should be ok?
