Hey guys,

having a strange Macbook Air 13" here.

external display works fine / chimes

water damage - had corrosion around the display-cable and connector.

replaced cable + display - sometimes i a got a image/backlight - when its tries to boot into the os - black screen is coming up. one time the apple-logo and progress bar were super small / not the regular size of the apple-logo...

what to do?
