MisterMsk Posted May 13, 2016 Share Posted May 13, 2016 Hi All, I have converted my Vader Atari 2600 over to composite a while ago. Recently, I started seeing these static hum bars going up the screen. Really wide. One very noticeable and another one on the screen not as noticeable. They slowly move up the screen. I don't remember them before. When reading about hum bars if I have two that means that it is a 120 cycle hum. I assume this means power supply maybe? I don't want to have to go out an buy another power supply if it is not. Any assistance would be appropriated. Quote Link to comment Share on other sites More sharing options...
Andromeda Stardust Posted May 13, 2016 Share Posted May 13, 2016 Pics? Is it affecting audio, video, or both? Quote Link to comment Share on other sites More sharing options...
