What has happened to my screen?

*my camera is the Nikon coolpix s32 rather than the s33, but it didn't show up as an option so thought this was the closest*

Hi, so the screen on my camera was fine about 20 minutes ago, but then it started to dim and within 1-2 seconds, it was really dark. It was very close to being completely black, but I could still make out some of the white symbols, etc. I turned it off and tried again, and the screen remained dark but began to flicker slightly. Just a few minutes ago, I went to turn it on again and the screen didn't light up at all.

The last time I used this was on my DOE practice expedition, and it got slightly damp in my pocket, and you could see traces of water on the screen, but then I dried it up and moved it to a drier place in my bag. As it's a waterproof camera, I assumed this wouldn't affect it, and all of the ports and things like that were closed properly, so I really don't know.

We're going on holidays on Wednesday (three days from now) and I really wanted to take it with me if I could get it to work, so is there any way I can fix it? And I'm almost certain that the warranty was ran out 8 months ago, so if I can't fix it could you recommend anyone? (In the UK)

Thanks:)
