I recieved a non poasswored Macbook Pro Mid 2012 A1278 , The Laptop Start turns On and the FAN spins but no image on the screen, i tested reseat ram sockets , clean ram sticks with pencil eraser, and i reballed both cpu and chipset chips, now im starting to think maybe the efi chip is either bad or the dump inside is corrputed. I also test the Laptop with VGA and HDMI cable and nothing, i get no video on external screen.
Here i attach the Dump i got from READING spi Chip using CH341a SPI programmer
