I noticed that the schematics are not available right now, so I'm going to give you a generic answer.
Clean the bright switch. In all of the preamps with the bright boost circuit, the switch is similar to that of an FX floor pedal. The circuit is bypassed in one position, and in circuit in the other position. If the switch gets oxidized, the signal can be cut off or reduced.
Spray a little deoxit into the small holes on the back of the switch and work the switch back and forth a few times and see if the signal comes back. If one application doesn't fix it, try a second and even a third application before you give up on it.
You can also try and bypass the switch with a jumper lead to see if the signal comes back.
