Why is my screen not coming on

@grizz51800 the last thing you want to do is to continue to try to start it etc. That can potentially make a bad situation worse. Remove the AC adapter and the battery. Then it is time to tear it down. you will need to remove the motherboard and all. Once it's removed, time to clean it with some 90% (or higher if you can get it) isopropyl alcohol. Follow this guide, and even so it was written for an Apple iPhone 3G, all the points are still pertinent to your computer as well. While you clean your board, check for any obvious damage, like burned or missing components etc. Best thing to do, would be to clean it with an ultrasonic cleaner, but if you do not have access to one, this will at least help.

Once all this is done, reassemble your computer and reevaluate. Until it is cleaned, everything will only be a guess. It is possible that you have a bad display connector (shorted out by the liquid), display cable or that the top case and/or keyboard may need replacement. To work on your computer, use something like this video no the exact same model but it should still help you working on yours.

Make sure that you take some good pictures of your motherboard. Both sides. Those may be necessary to identify your motherboard in case it'll require some board level repair. 在已经存在的问题里加入图片

While you work on your computer, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
