Hi all, working on a Apple MacBook Air A1466 (Logic board 802-00165-A). No chime or image??? Where checked the voltages on the main logic board, nearly all are present, 3.3, 5.0, 8.6, 1.6 for ram & CPU Core all present, ALL_SYS_PWRGD & CPU_VCCST_PWRGD also present & even get a normal fan spin. All voltages on the SPI_ROM are present. I even replaced the rom with a known good one but still no image or chime. The LCD backlight voltages even are normal. Can anyone help me in this? Am I missing any voltages yet to be checked. Thanks in advance.
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Original problem was liquid spill & no ALL_SYS_PWRGD & CPU_VCCST_PWRGD voltages & no fan spin. Cleaned & replaced all the corroded parts, then all started to work but no image or charm after that.. anyway I will do . PRAM reset as "piernov" tell me to do so & then back to you guys again.
