    Default SNES black screen of death

    Bought a console off ebay. Person said it was in storage. Opened it up, lots of dead bugs and their poop. Cleaned the whole thing out as best I could with 91% alcohol. Board has rust and corrosion all over it but still powers on. Went through and found and repaired some broken traces on the board and recently got the console to work. Was in the middle of playing Flashback: The Quest For Identity when suddenly it crashed. Couldn't get it to play that game again but it would play other games. Then several minutes later I suddenly couldn't get any other games to work either. Don't think the board gets hot enough to melt the solder I used but checked all the traces for continuity anyway and all of them are fine. Still a black screen. It's not the pin connector, power supply is original, removable sound board is good, tried both RF and A/V ports. Thinking it's one of the chips, but why would it suddenly go bad without any warning? Games were perfectly fine with no issues AT ALL. A visual inspection does not reveal any answers. Very stumped on this one. Any ideas? Thanks!

    Just replaced all the capacitors. Still no picture or sound. So now I'm pretty much down to just the chips being the issue.

    Console is just for parts now unless anyone has any ideas.

    Are any of your jumper wires bypassing resistors or anything?

    I have one like this, no rust or any thing but just nothing.

    some time I can get the Capcom logo or konami to show up but otherwise it is something similar.

    if it weren't rusty I'd say it was worth keeping at it but if yours s pretty rusty then i'd set it aside as parts and move on. once the oxides take over its kinda a lost cause before they take something else out

    No none of them are bypassing any resistors. But I think if they were it probably would have become apparent pretty soon. I had been playing Flashback for over an hour before it started acting up. Had almost beaten the game too.

    You're probably right. Which is unfortunate because many of the parts on it seem to be pretty good. Maybe I'll keep messing with it just to give myself some additional circuit experience.

    I'll take a few pics of it in the next day or so of the insides just for reference.

    Solder melts at something like 350F depending on the alloy. I love that people think their 360 failed because the solder melted but at that temp you'd seriously notice it getting that hot.

    The hottest component on a SNES is probably the 7805 voltage regulator. They get pretty toasty without a heatsink attached but hardly hot enough to melt solder.
    I fix things. You name it, I'll work on it. Want something modded? Recapped?
