phone wont turn on but will show ligthen and another sign

@chaz95 before you do anything else, you want to take care of the water damage issue. Right now you do not know what damage you have.

For now you want to stop trying to charge, sync or otherwise use your phone. This potentially can make a bad situation worse.

The very first step I would take is to disassemble your phone. You will have to disassemble your phone. Take a careful and close look at all components and connectors. Truly assess the damage. Look for major corrosion, evaluate the pins in the connectors etc,. Take a look at all connectors as well as cable ends. Remove all the EMI shields off your board. Once you got the gross contamination cleaned, use 90%+ isopropyl alcohol and clean your parts some more. For a proper cleaning, use this guide. It was written for a Apple iPhone 3G but it is still pertinent to your phone as well. I can not stress the importance of a good cleaning enough, so do it over and over while replacing the alcohol after each cleaning. Do not use compressed air for the cleaning since that can drive liquid as well as corrosion particles into areas that will cause trouble later on. Also, you do not need to leave it to dry for a day. Isopropyl alcohol in the higher concentration will evaporate quickly and dissipate the water. The importance here is the cleaning. If you can, get it professionally cleaned Do not forget to replace the battery. This is a must and not an option. It will fail if you do not take care of it now. Keep in mind that water damage is the hardest to troubleshoot and to repair. Until you clean your phone properly, you cannot do a proper troubleshooting. If you do not clean your water damage, your phone will eventually fail from corrosion damage.
