I used it for a year without problems but out of nowhere it stopped working. I cleaned it and i have tested all i could on another system that works. But i still cant find out why it wont show video. I got it so it would at-least give me a black screen. so its giving a signal but it still wont give me a picture? I have tried everything i can. Here is all that i does Has power and red light black screen no sound gives signal (the tv does not show no signal) all parts work on my other one Update (10/19/2018) I got it! Turn it on without the cartrage TV should say NO SIGNAL Put the cartrage in (With the N64 on) Turn the n64 off then on should turn on Update (10/20/2018)
This sounds more like a video processing problem internal to the unit. Without seeing the unit and scoping some of the traces inside, this will be tough to try and resolve. Parts of the video output section are working as shown by the black screen. What needs to be investigated is why the black screen. It could be either the input to the video processing IC or the IC itself having an internal problem. I will check around to see if I can find any suggestions. Dan
I just grabbed mine out of storage, as well. It had the same problem. I tried different cables, power supplies, taking the memory out, flipping the power switch on and off rapidly, etc. But what fixed it was I took the cables out, then took the memory pack out again and blew in the memory card slot. Cleaned around it. Put the cables back in firmly and it works like a charm! Troubleshoot and troubleshoot! I hope this helps!
