Black screen,loud fans, LED 3 off
My problem is when the power cable on, the LED’s #1 & 2 are on, hit the power button, I get the Bong sound, but LED #3 &4 are off, the fans is normal, but after half past minute, the fans begin ramping up with a loud noise, screen still black.
Is the problem is logic board or the LCD display? If the LCD display is ok, I want to change it just like a display
I removed the HDD, so I don't know how to run diagnostic services, can you tell me? I will be very appreciative.
Here is what I did, I connect the keyboard and try to hit the cmd+alt+r+p, buttons and power up the system. I also tried hitting the button under the CD player, even changed the battery on the logic board, nothing worked.
I’m desperate now, maybe the logic board has a problem, the price is high now in eBay for a replacement, so if I can know the LCD display is good, can I transfer it to a screen to let my Mac Mini use it?
So,here is my problem and questions if someone can give me some help I would appreciate it.
Questa è una buona domanda?
