I've got this 820-3115 that doesn't post video on internal display. video works great threw the thunderbolt port. i can see that the back light is very dim and no picture. the machine did have very minor liquid damage around c3888 and r3880.
ppvout_sw_lcdbklt-- 27v
L9080 pin1 and 2 are 1.4v
pp3v3_lcdvdd_sw is 3.32v
pp3v3_s0 3.32v
i have changed the lcd connector as i had the pins smash and touching each other.
not sure what I'm missing any ideas would be great.
