GFI Popped and Won't Reset

Thank you all for your replies. We have tried all of these except for replacing the outlet itself. We called Lazy Days and will be bringing it in for them to look at as it's under warranty. We tried the hidden button trick, running the generator, unplugging things and then plugging them in and nothing has worked yet. We thought it might be the outside outlet as we had heavy rain but nope. Or maybe I had splashed water on the kitchen one but no. Or a problem at the pole, but we have a Progressive power surge protector and it says zero errors. We do have power, the tv and blu ray work but not the outlets nor the refrigerator. I will update when we find the problem.
Thanks again everyone
