Q: PowerBook G3 Pismo yellow screen
Hi, my PowerBook G3 Pismo has a slight yellow tint on the display. Can someone tell me what part I would need to fix this or is a whole new LCD needed? Thank you.
PowerBook, Mac OS X (10.3.x), G3 Pismo

It sounds like the PowerBook's backlight is becoming dim. Old laptops use a backlighting method called Cold cathode fluorescent lamps (CCFL). Unlike the LED method used in modern laptops and LCD displays, CCFL fades over time and usage.
You can buy the specific (new) part used in the Pismo, for example (I think it is one)

but it takes specialized skill (and major disassembly) to do the work, and the part itself is very delicate. An easier fix is to replace the complete display assembly (the entire top half of PowerBook with LCD), but you are getting the replacement from another used PowerBook, so it is likely to be somewhat faded as well, with unknown remaining lifetime.
