This video is Part 2 of 2 of a Super Famicom (Super Nintendo) Jr repair. I purchased this at goodwill with a note on it that said it only outputs gray blurry images, with no further details. This video shows all the steps I took to diagnose and attempt to repair the console. The particular problem is the blue signal is missing on this board for RGB output which causes any game played in this console to display with no blue colors.
