| Bondi Blue CD hints? |
Posted by: Cam on 2023-10-28 17:27:22
Hi!
I picked up an imac Bondi Blue this past week, and managed to get everything restored and working (dead hard drive replaced with n SSD, OS loaded), with the exception of the CD-ROM drive. It's D-E-D dead.
The drive doesn't spin up, or eject when the button is pushed. Does anyone have any advice on fixing it?
I see a couple of capacitors I may replace and see if that makes any difference.
Thanks,
Cam
Edit: I should have mentioned it's a tray loading drive, not slot loading. |

Make sure everything is seated properly. Any chance a disc is stuck? (Should be able to put a paper clip in the front).
Worse case. They’re actually not that bad to replace IMO. (vs. The slot load models). Just fleabay a PC laptop CDRom (or CDRW or even a DVD) IDE drive. Key is IDE.
The bezel may not fit if it’s a different brand from your OG. But some glue can be your friend here if needed. |

I considered another kind of CD drive, and just transferring the bezel over, but the bezel appears to be glued on? I guess worst case (if recapping doesn't work) is transplanting the drawer from the broken drive to a working drive, and hope the problem is in the pc board. |

OK, just to complete the documentation on this in case someone if the far future is looking at a similar problem.
I recapped the LB (even though the machine works) because . . . well capacitors that old are begging to be replaced. Once that was done, the CD-ROM came back to life!?
I'm speculating that one of the caps that got replaced was part of the power circuit that fed the CD-ROM, and replacing it brought the power rail back in line??? At least that's my best guess. I could be wrong, and more than willing to 'no you're wrong' feedback on this.
The last problem (not really a show stopper at this point) is a high pitched whine that fades away 20 seconds or so after being turned on. I hope it's not the flyback.

I have the same issue with my SE - high pitched whine. I recapped the PSU and it didn't stop (but the voltage rails become more stable).
I heard from some people it's the video circuitry, so I'll be recapping it in the new year.
If that solves the problem I'll be sure to let you know! |

Until my mid 20s I could hear if a TV was on in the next room even if it was muted, just by the high pitched noise they make. |

I am actually (in fact I turn 17 tomorrow - surprise surprise, I'm actually young!).
I figured out the frequency was somewhere around 18,000Hz, but with my SE it does go away after a little while.
I have a little Samsung TV that has the high pitched sound and it's really loud and annoying, so I don't use it often.
Guess I just have good hearing? |
