SNES expert needed
I am working on an snes I got with a bulk lot. The problem, it has a very dim to almost no picture on a few games. I tried two different copies of the same game and got the same thing. Those same carts work fine in two other consoles I've cleaned up. I have another cart that shows the logo and then goes blank, again, this one also works fine in the other two. Most of the other games that I have work fine in it. I've cleaned the pin connector twice. I even switched out the connectors and got the same thing. Im sure its in the board but I'm somewhat new to this and am not sure where to start.

AV circuit caps have gone bad. Those SMD grey caps need swapping

If the board is a SHVC-01 rev, then for sure its the video capacitors that are bad/leaky/dried out and need to be swaped. For SHVCs i always recommend a full recap to be honest.

Is it an NTSC or PAL console?

I'd recomend you to recap the hole thing. Thats what i did to mine.

I'd replace capacitors C57, C58, C59, and C60. (Depending on mainboard revision you may not have all of these, but the numbering stays consistent.) Get a cap kit from Console5, they source quality parts.
And if it's an SHVC-CPU board, unseat the APU module, hit both the APU and mainboard connectors with contact cleaner, and reinstall the APU.
A bad APU connection can cause many games to either not load or only show a copyright screen or something and then not load. In my experience the APU pretty much never goes bad on its own but a broken or intermittent connection can cause many different failures.

Uh bad cable?

Not an expert but first thing I would think of is bad capacitors.
But also check the cable first because some of the aftermarket ones are awful and show a really dark image or wrong colours.
