About 7-8 months ago, I brought my camera sony cyber shot DSC-WX80
one day 1-2 drops of water fallen on its screen,than after cleaning it with dry cloth,I found that it is showing only black colour nothing else.But then too all other functions like caputring,recoding,e.t.c. are working properly.
Please explain me this technical problem in detail and also provide suggestions to repair it?
