| Power Macintosh 5260 Flyback |
Posted by: lem150 on 2024-11-24 15:18:37
Hi, I have a 5260 that is having some issues. I have done a full recap and the logic board works fine (I tested it in a 6500). It turns on (most of the time) but there are some click sounds and a loud sound from the CRT startup. I have a video to see. Is this the flyback going? Does anyone know if I can get a replacement somehow? |

From startup, that sounds OK - slight crackle as the CRT turns on and then the "donk" being the degauss function.
A failing flyback would be more evident over using it for a while. If you hear the CRT snap and crackle under normal use (or it might turn off for a moment), have a look at the flyback in a dark room and see if there is any arcing from the unit. |

So it is turning on regularly now, but it wasn’t yesterday. I did reflow the psu caps. Could there be something wrong with the psu board? |

Give it the board a tap while on - turning on and off would be suggestive of dry solder joints. Yes, PSU caps ideally need to be replaced for long term use/if you love it. |
