A1502 Scrambled Video...

[Aldizi]

The video scrambled like in checkers.. I unplugged the video cable and plugged it in agn. I also unplugged the battery and plugged it in again the issue is gone but I have feeling its going to come back does anyone know what causes this? He said he dropped it lightly and it has no visible signs of drop damage so I believe him. Can the lcd be dmged is this a symptom.

Do you have another assembly to test? If not, try use external one.

All UMA video so scrambled video is usually related to RAM. As this was dropped it is probably a broken trace and the board is scrap. If issue returns this is probably a no fix.
