@abde19 just like suggested before, post some pictures of what this all looks like. Outside of the screen will be no issue. Just wipe it off. Inside of the screen could become a major issue. The water may just cause some cossorion damage on your screen. The best way of trying to fix it is by disassembling your display and cleaning/ drying all the components (LED Matrix, diffuser sheets etc.) Yes it's a bit of a PITA but it may just keep your TV around a bit longer. .
