Super Nintendo: Powers on but seems dead

[Tokimemofan]

I have several of these sitting around at the moment, I have ruled out the cart connector and SHVC-Sound units, Screen flashes normally on power on but the game never loads. I checked all cables.

Have you checked the 7805 in them?

I'll do that today.
Edit: tested them, they work, besides these units seem to power on (the led lights normally) but games don't load, as mentioned the video encoder seems to be running enough to put up a black screen. BTW I am having the same problem on at least 3 revisions of the hardware. Only one of the 5 units with this problem has had a fuse replacement.

It's a dead capacitor issue. The surface mount caps on the video-centric areas of the SNES board love to fail with age (just like with everything else from the 90's) but it's an easy and cheap fix if you can solder. I had to sort through a pile of dead systems I got in a bin of so-called 'broken' consoles from a local games store and fixed all but one of the SNES'es that was in there.

I doubt it, I tried moving the caps from a bad unit to one that had a f*** controller port IC and the they seemed fine, besides I'd expect some visible abnormalities on at least 1 of the caps in any of the units. I also have the fact that these units have potentially had repair attempts done before, the only low hanging fruit repairs so far have been fuse repairs, and 1 broken power port, these also range from being heavily used to near mint. I already gave up and moved on from these.

Sounds like a dirty cart port to me.

I tested that, that wasn't it.
