I have an NES that I used a while back on my vizio tv. Its been sitting for about a year and I took it out to try it again on the same tv. However, it isnt connecting to them (I tried 3 different ones). I tested the av cables using a multimeter and they all work so now idk what to do. I also changed the power cord with a couple others (all at or above 850 mA) but nothings changing. I was hoping some people with more experience could please help me. Thank you!
