HI All,
Macbook air
Sometimes boots normally and functions 100%.
Other times, fan will spin, with no video or chime.
Board looks good with no obvious signs of corrosion.
Not a backlight issue. Will sometimes chime and boot normally. When it does not chime there is no video / backlight.
When it does not boot
- Fan spin 100%
- Draws approx 115 ma on bench power supply
