Display is not working (no apple logo light)

Short story:

I took my MacBook Pro to an Apple authorized service center to replace my display for stain-gate program. They told me my system had liquid spills but they can replace the display it at my own risk, I then accepted. Now they give me my laptop with new screen but the screen is black.

  • Its’ working with external monitor through HDMI.
  • Apple logo doesn’t light up
  • I’ve already tried reboot methods holding keys but didn’t worked for me.

Please help me telling me which part could be the problem to find the right technical service in my city.

Answer this question I have this problem too

Is this a good question?

Take a lit flashlight and shine it through the back Apple Logo. Are you able to see your desktop icons? If you do then your logic board needs service.

@pazbaraybar - At this point you'll need to inspect the display connector on the logic board and the cable for corrosion as the video signal is not getting to the display. Take some pics and post them here for us to see Adding images to an existing question

I see some corrosion on the pins, someone with good micro-soldering skills should be able to clean up these solder joints. Hopefully thats all thats needed.
