I need help with my SNES and couldn't find an existing console mod/repair thread.

Anyway here's my issue, I have an original North American SNES that has recently begun having issues rendering mode 7 effects. Most sprites will flicker in and out of existence while undergoing mode 7 transformations, for example the pendulum on the Chrono Trigger title screen doesn't even appear at first and only pops in for a second or two at a time until it comes to a stop, after which point is stays on screen as it should. There are some mode 7 heavy games like F-Zero and Mario Kart that don't seem to be affected at all however.

So far I've tried cleaning the cartridges of the affected games as well as the cartridge connector on the system. I've also tried cleaning the contacts on the AV port and swapping AV cables. Nothing seems to have made a difference.

The only help Google has been able to provide is SNES burn-in test ROM which I ran on my flash cart. Everything passed just fine except the final mode 7 scaling test, where the sprite being scaled disappeared for a second or two at a time, though not as frequently as they tend to in games. I should also be noted that the mode 7 rotation test from the same ROM worked just fine. The most recent thing I did before posting here was open up the SNES to check the board for bad caps, but couldn't find any.

Has anyone encountered a similar problem before or have any idea how to fix it?

I guess the old one is gone. If I missed it, sorry.
