Looking for schematics

I'm taking a computer engineering course, about half done right now. The realisation that I can likely repair my old CD player has hit me. From the research I have done, my Alpine CDA-7840 deck has a transistor that drives the display lamps behind the LCD screen. However, any amount of googling I have done has left me nowhere as far as schematics to locate this transistor, which does not light the display 99% of the time. The actual display is very well concealed inside the faceplate, and I do not have access to see any of the parts of it, otherwise I would just trace it.

This is a side project, as I finnaly bit the bullet and replaced the head unit, but I figure, what the heck. We have some really nice soldering equipment at school, so I am confident I can replace this transistor.

Does anyone know anywhere to try and get schematics, or should I just try and locate the bad transistor manually?
 
does this transistor have a serial number? I dunno why you would be looking for a schematic of a transistor... it's kinda... just a transistor. Maybe you're referring to an IC chip that contains multiple transistors?
 
I don't need a schematic for a transistor, I need one for the unit so I can find the transistor that drives the display lamps.
