Odd Display Backlighting Behavior
Hi! So I recently picked up an old Powerbook G4 and noticed a peculiarity with it.
When I turn the machine on, the backlight turns on initially for about a minute or so, then just goes completely dark. Shining a light on the display reveals it is still displaying image correctly.
Furthermore, , most times it does it, but rarely it doesn't, and even rarer so it does it, then about a couple minutes down the line the backlight comes back to life.
I'm not even sure where to begin on diagnosing the issue with this machine, or where to even begin looking for replacement parts.
If it helps to know, the battery for certain is completely dead, and I am sourcing a replacement, if for some reason my primary issue is somehow related to this.
