Please help me!

Alright, heres what is happening to me. I Came home from a show i played at and i re set up my amp in my room to practice. My amp is a fender princeton 65. I plug in and my amp is on but there is barely any sound on it whatsoever. I check the chords and they are fine. An i know its my amp and not my guitar because it works on other amps. When i turn it up to ten i am barely able to hear it I have no idea what it is and my amp has never done this before. If anyone can tell me what might be the problem i will be forever grateful. Thanks in advance.

There are a lot of things that can be wrong. And without having a look, it's impossible to find out why it's acting that way.
I suggest just taking it to a repair shop.
