Hi,
I bought this shit from craigslist.
The lady said she spilled some water on the macbook.
She heard some sizzling and she couldn't turn it back on anymore.
The macbook is in a pristine condition.
I took it apart and I couldn't find where the water was spilled.
No corrosion on the board. Maybe a little corrosion on C3897,
I cleaned the whole board. After I dried it I attached the power cable and it turned on.
I attached the speaker and I heard the dong sound. I put it back to the macbook and it didn't turn on.
I disconnected all the cable except the LVDS cable. It still didn't power on. After I removed the LVDS cable it turned on.
I tried with a different LCD same thing. I replaced the LVDS connector. Still nothing. It won't even try to turn on.
It doesn't do anything. Fan is not spinning. Nothing at all.
I pulled the backlight fuse. I thought maybe something with the backlight circuit. No luck.
I pulled L9004 and it turns on. Has backlight, but of course no picture. I checked everything for short or low resistance.
I replaced L9004 and U9000. These didn't solve anything.
I pulled C9011 and C9012 and C9015. Same shit.
I pulled U9000 again and solder a wire from Pin 2,3 to Pin 4,5. The 3.3V rail is jumping up and down and it does not turn on.
I know my test LCD is good. I just used it yesterday. Anyway I would believe something is wrong with the LCD.
Any thoughts?
Thanks!
