820-3115 board. came in water damage.
now it chimes but i get no image (when i shine a light on the back i see no apple, also not with a different screen.)
i have 3,3volts on J9000 pin 4 so it is recognizing lcd.
I am missing LCD_IG_PWR_EN 0Volt.
LCD_IG_PWR_EN comes from U1800
but am I wrong to think if I get a chime then u1800 gets power?
what am I missing
