The lcd could be the problem. You’d have to try another screen to see. If there’s water damage,there could be a short. If there’s a partial short to ground,it can cause issues with not enough power to the backlight. As for moisture or water damage,opening the phone is the first step to dry it out. Powering it on is a bad idea potentially,especially when it’s wet still,since this can damage it further. I’d backup any important data now in case. But you could have it sent out to be repaired.
