how can i fix my TV, 54cm?

You should have taken back off and dried with hair dryer.Then it would work. You turned tv on to soon with water on board so any part in tv could be shorted out.See if you can get a hair dryer and dry it out inside, make sure it is unpluged, then give it a try. If that doesn't work seek tv shop. Should never have water above tv, but i've seen that happen before .Some work after they are dried out real good. Still a chance.
