How to fix Mac black screen and not turning on issue?

error - Why does my Mac Pro running Snow leopard freeze on blue screen on shutdown? - Ask Different

The LVDS connector is a very small and delicate piece but the LED backlight needs quite a lot of current compared to the size of the pins. I figured out what was the cause of the problem when I removed the LCD. Its socket yes, from the LCD side, not from the laptop mainboard side was almost burned, perhaps because of the moisture.

Cleaning it carefully solved the problem. Resoldering may also help, which I also have got done. The socket was also making the backlight appear uneven there are six pins responsible for the LEDs, fault of any of them will cause the effect. Dreading that drive I decided to try again. Here is a description of my problem and the solution….

Yay, the solution! When I turn on my MacBook Pro there was no sound, and no keyboard lights. The only way I could tell it was on was to look at the Apple icon on back of the monitor, it was lit up. Since I had no sound I waited until I saw the apple light up, then I tried that sequence of keys. After I got off the phone with him I decided to try it again, but this time I did not wait until the apple lit, and right away I heard the beep and it started correctly.

So glad to hear that sound! I had the same issue. Machine starts but screen stayed black. Works fine if I plug into an external monitor. My machine falls into the group that Apple is repairing free of charge but this only continues through Check with Apple. I dropped my MacBook Pro and almost cried. Thank you so much! Please help me out or email me lleade????

    I was not having enough space to save new files and all. Also running several software programs for my work. That lead this problem. Later i ve moved all the data to another SSD and removed few software programs. In my case cooking the logic board resolved the issue. It looks like over time the contacts tend to loosen up.

    After about 10 minutes it rebooted and everything was gravy. So long story short, if you get a white screne, try to enter your login credentials and see what happens. Thanks for the tip, Don.

This Fixed it for me!!! I had tried every other suggestion in the article short of an OS restore and this OS recovery over the internet is what did the trick finally works like a champ now!!!

    Thank you for posting this tip! If you get a white screen, many times you have to power off the Mac. Most of the time I can usually ssh into the hung Mac then run these commands from the terminal of another Mac or PC:. When the Mac reboots, I then go into safe mode and follow your recommendations. I am click on the downward pointing arrow button but its showing white screen.
