    Default Micromega CDP. "Err"

    I've dug up my old Micromega Stage 5 CDP. It was my pride and joy for ages - but now years and years ago.

    It plays but more often than not when reading a disc it comes up with Err. Even on the same disc. So I assume the mechanics and/or laser needs cleaning or fettling in some way.

    Any guidance?

    I'll try to attach a pic of the CDP without its trousers on.

    Cheers

    Cotton wool bud on the optics. But usually its dried grease on the runners, worn door open cogs and sloppy belts that do for the Stage series.

    Thanks Simon. I'm always wary of going near the optics probably as so many people warn against it. But I guess using cotton buds is less intrusive than the cheap cd cleaners one can buy. Any risk of soaking the bud in isopropyl a bit? I tend to use quite a bit when reviving laptops/computers.

    Is it relatively easy to do a tear down of the mechanism to get to the runners, belt etc and what is the best way of applying new grease?

    Personally I wouldn't use anything on the Lenses.
    The early ones were Glass so OK but these 'modern' ones will be Plastic and can react badly to certain chemicals.

    Use a fine artists brush for the lens, or Badger if you have one - a brush with Badger hair that is.

    Thanks for that. We have lots of fine arts brushes around here, but no badger one.

    I've been looking at utube and found some guy who did a partial tear down for the belt replacement. Will tear down tomorrow to see how the belt is doing and get a better peek at the mechs.

    It seems that these Micromega Stages were notoriously unreliable (mine lasted for years though) which basically bankrupted the company due to the high level of returns. I'll probably not spend too much time on this but would be great to get it working reliably.

    Need to research lubrication for the runners.

    I have always cleaned lenses with Zeiss photo moisture tissues. Heck I have even cleaned my dslr sensor with them. Material is of a special type so virtually no scratch possible and special liquid cleans nicely and evaporates completely.
