Answer to "Why is the Display white but an external Monitor works fine?"Is it possible to replace the display data cable without damaging the display screen as in the case of attempting to remove broken hinges on an M8407 model? I see what the inverter looks like and now know where it's located so I'll check out the connection there also. I assumed the for parts display screen would work as the seller indicate is was working before it wouldn't bot up?
Answer to "Why is the Display white but an external Monitor works fine?"Hi people new here. I too have the same or similar problem. I inherited this 2001 Mac Powerbook G4 M8407 with broken hinges initially. I took it apart to remove the display and hopefully consider replacing hinges. After the fact I was going to purchase used hinges and replace them, but almost to costly when I got a complete used for parts unit. I was able to get the original unit working with the display screen removed using external monitor. I have subsequently installed used display screen complete with hinges and now find that the same thing people are describing here happening to me. I can get the laptop to work using external monitor but only have white screen display on OEM display screen, I can however control the brightness, so not sure what the logic board or inverter looks like or where it is? Hopefully someone else can help as well. Thanks, Ron
