TAPE BATTERY IN WITH SCOTCH TAPE FIND A DAMAGED PHONE ON EBAY FOR PARTS

probably too late but he first thing to don in that sit. is rinse the phone in a 75/25 solution of alcohol and water. then open up as you did and let it dry. if you can see water on the display screen your probably out of luck but keep it warm and dry for a few days and see what happens.

Yes, I've seen this happen twice, similarly. When enough shock has been applied to a phone, such as your case, the screen is very susceptable to damage and will need to be repaired or replaced. There's nothing you can do with expertise or spare parts unfortunately, you may even want to look at a new phone if the warranty is out on the phone. Sorry to be the bearer of bad news.
