I accidentally spilled water into the fan part and now it won’t turn on
If you spilled any liquids that might got into the console, I recommend taking it to a good repair centre locally.
Or if you have the materials and you think you have enough experience, open the console by yourself clean every part with isopropanol and check for any rust. Clean the rust of with a brass brush or something, check for any water damage at the power brick. And try to turn it on.
Any update on what you ended up doing?
