| Smoking SE/30 flyback transformer? | |
| Posted by: pcamen on 2019-10-26 08:40:52 A few months back I fired up one of my SE/30's with a Carrera 030 card and a video card and heard a pop and smelled smoke. when I opened it up, the video card was blackened like a component in it had let the magic smoke out all over the board. I've never seen something like this before.   Yesterday, on further examination, I came to the conclusion that the black on the video board is just dirt; there is a bunch of the same black stuff on the side of the CRT directly next to the video board as it sits stacked on top of the Carrera. https://vintageapple.org/pic/crt.jpeg Turning on the unit conformed my suspicion; the flyback transformer, or what I believe is the flyback transformer, was smoking readily. I tried to take a video but all it caught was the same item sparking. https://vintageapple.org/pic/sparks.mov Can anyone tell me how exactly the flyback transformer goes bad? I have an extra analog board from the SE/30 I dropped a couple of months back. I'm just curious that doesn't seem to be the most common failure. Pictures: | |
