check in the menu under picture or video settings and see if there is options for the inputs. some tv's allow you to disable inputs for faster switching. if you only have a dvd player but your tv allows for 8 input devices, you're always having to press the button many times to go from tv mode, to dvd, and back. disabling inputs allows you to switch between only what you use.
press menu and navigate to the video settings. if you see "inputs" or "labels", select it and you can probably activate and deactivate inputs. my guess is the one you are trying to connect to isn't "on".

is the mitsu tv a crt(picture tube type) or lcd/plasma. If it's the later it could be worth the repair, if it 's a crt type tv it might be that some parts will not be available, but in order to find out you'll need a better description of the type of tv , the size of screen and a better detail of what the problewm sounds like. Another thing that may persuade you to making the decision on wheter to fix or not is how familiar are you with electronic replacement, like desoldering and soldering technics and or location of circuits once you open the tv. Hope this helps
