Default No image on Macbook A1278 which is 820-3115
The laptop turns On and give the chime sound, meaning the CPU is working 100%, but i have no image on the screen.
U9000 have 3.3v for data line on the input side but 0v on the output, i knew that there was nothing wrong with U9000 since it was not being told to turn on, anyway i reomved the chip with another same one but still no 3.3v
L9004 has 0v
L9008 has 3.3v
