I bought an SNES and when I try to play Street Fighter 2, the "Licensed by Nintendo" screen comes up then it goes black and nothing happens. This is the only game I have but it works on 3 other SNES I have. I've done the obvious such as cleaning the game and cartridge slot. No capacitors looks obvious blown and the Red LED comes on so the fuse isn't blown, though I doubt the game would boot if it was. I'm thinking about disabling the lockout chip possibly. That fixed my NES that wouldn't boot.
I disassembled it again and now it doesn't even turn on. I guess I blew the fuse. I replaced the fuse with a wire for now and it turns on again, same issue.
I bought Madden for $1 at a store and it just gives me a black screen. I can't find any solution for this. I put a working connector into it and it still doesn't boot.
Replacing the fuse with a wire isn't going to do you any favours. Part of the fault your console is having is likely causing a fuse to blow. When it occurs a second time, which it will, if it hasn't already, you're going to lose more than a fuse.
It wasn't the fuse at first, the power cable has a short. So far I've redone the fuse, disabled the lockout chip, desoldered the reset button, swapped connectors with a working one, cleaned it with alcohol. Nothing is working. I just get a black screen and a red light now.
I can't edit posts on my phone so forgive me. I tried this and there were crackling sounds and the room smelled of burnt rubber. If the SNES wasn't fried before, it is now. It doesn't turn on at all. 1: Obtain voltmeter 2: Connect negative voltmeter lead to perimeter ground of circuitboard 3: Set voltage range to 20v 4: Turn SNES on 5: Touch positive lead to leftmost pin - should be around 9V 6: Touch positive lead to rightmost pin - should be 5V 7: Post results I know what I did and it's embarrassing but the leads were switched.
Bad ram ic since most chips in a snes is custom made chip no hope of repair I have a few snes motherboards one where the ram chip get too hot result black screen.
SF2 shows "Licensed By Nintendo" before doing sound hardware init. I bet you have a problem with the sound CPU or sound DSP/ sound RAMs... The games were coded in a way they can't run without the sound hardware working correctly. Edit: Japanese version does not show anything but only Capcom logo... Just mentioning ...
