Macbook Bonfire.
So I was given a white macbook that had serious liquid damage. I have just replaced the logic board. Now the screen doesn't appear to work. sometimes when the computer boots it shows a white screen, other times it doesn't work at all. The computer sounds like it boots. I'm going to go to borrow a cable to connect it to an external monitor now. If it still doesn't show video what the heck is going on ?
