Chosen Solution
I was sitting and playing on the n64 and then i tilted it up a little and the light went out. and there is no power! Also i was testing the another clean system but i accidentally put the memory controller accessory into then ram pac port and now it wont show a picture!
I found out there is a rip somewhere in the cable. a fix for now is leaning against something where it connects!
I took the thing apart and when i turned it on it worked so i put it together and then when i turned it on again it was doing the same thing again. repeated the steps and instead of the end result a confused look on my face and no light it came on o well!
try a new cable or possibly search on youtube
