Hi all,

I went down the rabbithole a few weeks ago of reading about PPU failure in SNES consoles, which is apparently the proprietary chip responsible for rendering graphics on the console. Allegedly, many people are experiencing garbled graphics, etc., and the PPU failing is the suspected cause in most cases. The unfortunate thing is that short of taking a working one from another console, there is no solution. 

I read somewhere that the chip is usually damaged by power issues, like a surge or just longterm innapropriate voltage. This wouldn't be an issue normally, but the capacitors in the SNES are now starting to fail, and some of them act as a buffer to "smooth out" the current going to the console. I did read in one case that someone was able to solve what they thought was PPU failure by replacing the voltage regulator. 

I wanted to document some of this conversation in case many people really do start experiencing this soon, now that our SNES consoles are getting quite old. Does anyone have any experience with preemptively replacing all the capacitors in the console to try to prevent this from happening, and would that be advisable?
