Replacing a broken screen for a friend: History as I know it
Screen was cracked a couple months ago. They continued to use it as best they could, since they could still make out about half the screen. At some point, they go no image on the screen at all. Then they gave it to me to look at.
I plugged it up to an external monitor and it booted up fine. No activity on the broken screen at all. But everything else appeared to work fine. I told them they could order a replacement screen, but there might be another issue.
They ordered the screen, I put it in.
Still no video on the Screen. External Monitor solution works. But now, the trackpad does not appear to work (It worked before I replaced the screen).
So, any suggestions on what to look for on the screen not working?.
