    No hisotri. MacBook suddenly stopped working. I replaced all components because everything was burned. I had to rebuild the damaged pads. No picture on the external screen. Unfortunately I do not have another screen.

    Hi I have a problem with logic board A2179. I replaced the L8750 and the u8500. In addition, I replaced the burnt fuse of the F8400. I received a screen backlight but no picture. I additionally replaced u8595 but without positive result. Can I do more ?
