It is very easy to overlook small signs of liquid damage or the resulting corrosion especially under soldered components and within the extremely small connectors. Liquids can remain hiding beneath the various components for a while before the liquid evaporates or dries up. It is also very easy to break small surface mount components from the boards. I know since it has happened to me once or twice over the years no matter how careful I was cleaning the board.
Most likely components will need to be replaced, but which one(s) can be difficult to determine if you don't have access to spare parts. I would first start by connecting disconnecting the laptop's internal display and using an external display to see if the system is booting & functioning. Disconnecting all unnecessary items such as internal keyboard and trackpad and battery (possibly other items as well, but varies by model) may help as well so you can determine if the Logic Board core is working. Don't forget to check the ports for damage as well. If this does not work, then it is probably time to look for a new laptop.
Keep in mind even if you get the laptop working now, it may fail again in a few days or even a few weeks since corrosion will most likely set in at some point.

It sounds like your computer needs service.
Lucky for you, service is readily available from Apple stores (if available in your region) or Apple-Authorized Service Providers. Be sure to make an appointment, as they are usually very busy.
