How do i fix my 20" Philips Flat Screen T.V. Cable Plug?

I'm not an expert on televisions or how to repair them, however, i recently bumped my television into the wall while the cable for the television was plugged in. It resulted in, excuse me if this isn't the correct name for it, but the plug that the cable goes in bent, then eventually came out. The television turns on, however the screen shows nothing. Is this something i need to take to a repair shop or is there a cheaper way that i can do this on my own? Or is it even fixable?
