Hi,

got this macbook with no backlight. LVDS connector around ppvout_sw_lcdbklt pins was totally burned. Replaced the connector, got backlight back but no image. Mac is working fine with external monitor via displayport. Also tried another good display, no image still. What to measure?

White screen or dark screen with backlight present?

Bright white screen!

No 3V to LCD so either dead L9004 or dead U9000.
