I have a model 2 sega genesis currently that i still play pretty frequently. The issue is that the port where the power cord plugs in is loose and you need to either jiggle the cord or position it in a way to where the plug is kinda crooked so it makes contact and the system will stay on. Not sure whats caused this because the system doesn't move often, hasn't fallen, or had the cord pulled out hard as far as i know. Is there a simple remedy to this or should i get another one? I've always been kind of partial to the model ones anyway... It was the first one I had but i received this one as a gift and it has started doing this fairly recently.
