speedometer display not working after water spill

Hi every1 a few months ago, I spill some water into the speedometer side and it went dark ever since. So I got none of gas/fuel display, no speed shown. I usually drive slowly so I don't really need to know what speed but I still want to fix it. For fuel, I only rely on the right side of the display where it tells me how many miles left. Its a 2010 Prius gen 3. The speedometer is quite expensive to replace. Do you think I just blew a fuse that easy? replace it and done ? I don't know where the fuse is.
