darkchylde28 | 1,546 Posted February 10, 2022 Share Posted February 10, 2022 I watched a video about basically that exact thing a couple of days go. It's not the PSU, it's that the caps in the power section of the NES have gone out of spec, as converting the AC to DC causes interference, but taking straight DC from a third party/Genesis power adapter causes no issue. Basically, the power circuit doesn't have to "work as hard" when DC is input, since it doesn't need to be converted, so no lines, but when AC comes through, it's got to hit all the caps to be properly converted, and causes lines on the screen since they're not up to snuff any longer. Not a terrible job to do, if you've got the right equipment, but something you'd probably want to address sooner rather than later since electrolytic caps have a tendency to leak and destroy stuff if let go for too long. 1 1 Link to comment Share on other sites More sharing options...
drxandy | 3,225 Posted February 10, 2022 Share Posted February 10, 2022 Noice, very cool to learn about the caps. I was wondering about this last year or so.. I thought it was cap related but didn't get too in depth just got a replacement power cord and was happy it worked. 1 Link to comment Share on other sites More sharing options...

I wouldnt bother, if you are open to my advice. I spent 150$ on a “good quality” desolder tool and honestly using a solder braid/wick and a little patience is far better, if you have an OK iron. It takes longer but is more consistent. 1 Link to comment Share on other sites More sharing options...
