Why is the Display white but an external Monitor works fine?
My PB 12" 1,5GHz were running to hot last Summer.
After rebooting, the Display stays bright white and shows nothing at all. But an external Display works fine!? curious!
So I thought that maybe the Display is causing the Problem.
So I built in a new one (LCD only)....(some hours later)....there is still the same Problem: Display is white only.....
....so what is the Problem with my Machine? Which part could be the Problem?
Thanks for Helping me and Happy X-Mas
Model No.: A1104 Serial No.: XXXXXXXXRJ4
I tried the thing with the Flashlight but couldn´t see the desktop anyway.
PS: I have changed only the LCD, no cabbles or inverter..... THX
Now I´ve exchanged the LCD-Cable.....nothing happens, Display still white.
-So now the inverter causes my LCD problem for sure? I don´t want to buy/built in this Part just to keep the same problem....
Here a little question/thought of mine: (LCD INVERTER)! A good Friend told me that the inverter regulates the Backlight of the LCD-Panel only. My LCD is shining bright white but I can´t read or see anything on it. I´m able to regulate the brigthness, from white to dark. Because this works fine, I can´t believe that this part (LCD Inverter) is the curse of my Problem.........does this Part anything else than controll the LCD brightness? Someone can tell me for sure? ::::: (MAYER?) :::::: It took 6 hours and 80 Phillips Screws to exchange the LCD-Cable and the inverterjob will take too....... Is it conceivable that the internal GPU output won´t work while the external Display doing his job correctly? Logicboard (GPU) RIP? Or is this thought technical impossible?
PLZ PLZ HELP, THX FOR TRYING
I want back my mac(k) remnantlol
Es esta una buena pregunta?
the only things I can think about are :
1. the video connector on the logic board is broken or not making a full connection
2. the video cable from the logic board to the LCD panel is damaged.
3. the LCD panel is dead probably not in your case since you have a new one.Did it come with the inverter?
The only other thing I could find out was that you may have to use the F7 key to toggle to the monitor. If you can view the monitor, find the original OS X discs that came with your system, insert the one that says 'AHT Version x.x' in small print on the label. Insert it and reboot holding the option key down, choose the Apple hardware test, click the arrow to the right, and choose the extended test. Does it give you any messages? Of course I am not a Mac person yet an am new at Mac's but I do hope that this makes sense until the MAc Guru's on here are going to find the proper help for your problem. Good luck...Excellent I see mayer picked it up....help is on the way for you:)

Thanks mayer, but I like to just comment when I do not know the answer for sure. I like to help by getting the person to think about different options when I myself am not certain. Merry Christmas..
