Ok - need urgent help - DS was on the exercise bike (figure someone's butt may as well be sitting on it) and he likes to play with the buttons..

Now its got a high pitched squeal coming from it and its driving me nuts!! Any ideas how to stop it???

I looked at the screen - blank.

I pulled out both cords at the back of it screen - no difference.

If I have to listen to this much longer there is no guarantee that I will be sane by then end of the day. Help!!!
