Could it be the Interior Pins on bottom?

I have an original Xbox that have been modded and 2004 and worked perfectly up until now. There were blinking orange/green lights on it(which usually means that the av output isn't working properly). I ended up buying a new one and now there aren't any lights but the system still seems to be running with no signal . I checked with a flashlight to see inside of the av output . The top interior copper pins are all intact , but some of the bottoms are missing. Can this be a reasoning for it if so then how can it be fixed?
