Quoted from Animal:that happened with mine when it was relatively still new. I troubleshooted a few things and then the problem went away, not really sure what the issue was - wish I had an answer for your, but Im going to follow this thread to see what the solution is.
LOL, I had a similar issue and can't for the life of me remember what I did to fix it as it was a while back, other than I think it was a loose connector under the playfied that was making intermittent contact.
