So I have one of the rare CD players in my 1992 Camaro Z28 and noticed only lights in the dots for the radio buttons but nothing else. I am almost positive there were more lit up. I had taken pics years ago and looked at them recently only to discover what appears to only be 2 bulbs (for the dots that are lit up now) and are SOLDERED TO THE BOARD?????

I have not re-opened it up as it's a PITA to get to if I can just see my pictures I took before.

Pretty sure those back-facing bulbs act as a resistor or something and are not part of the radio backlighting.

Been awhile since I cracked one of those radios open,... but I'm fairly certain that the bulbs you need to change are mounted to the circuit board closest to the face-plate. ( remove the smaller board,... then remove the larger board that closest to the faceplate ) The backlight bulbs are much smaller & yes,... they get soldered in place.
