Well, there should be some kind of shutter between the light bulb and 
the sensor that lets more light through as you press harder on the keys. 
Look around area A-4 in the schematic here:

.  You should set some kind of lever move near the light bulb when you 
press the keys hard. Maybe the attached shutter fell off. I don't 
remember what it looks like - it's been over 20 years since I've 
owned/worked-on a CS60, but it should be pretty straight forward to fix.
