I had two mint, perfect condition ones which jammed up.
Had bouncing leds etc too.
Bottom line is this.. they can be fixed. Both mine didn't need parts - even though that was the reason given that almost no-one would touch them. What they needed was a strip down and all the electrical connectors cleaned/deoxidized. This is just due to age.
If you can find someone to do that, no problem. Dave Easterwood was the only person I could find who would do that. His work was excellent and the price was very reasonable (under $200 IIRC). But it took forever with a lack of communication which was worrisome.
In other ways this is the world we live in. Very few people actually want to fix things. The majority just want to replace parts.
By any chance, are you AKA Desmolicious? If so, howdy!
To echo what you said - full disclosure here - I got my CLE for a scant $250 from a super honest seller on the auction site. He was forthright about the dancing LEDs, which was of zero consequence to me, as I intended to shoot full manual anyway. I've been wanting one for years now, finally said F it and jumped. It's already paid for itself in pictures and pure enjoyment, as far as I'm concerned.
However, while waiting for the camera to arrive, neurosis set in and I began scouring the web for info on where to take it if something *should* need to be repaired, and... yep. Nada. The fella you mentioned.... maybe it was your post, but someone mentioned him going AWOL with their camera for a long stretch of time, and that frankly doesn't work for me.
Started trying to hunt down a manual... also NADA. I posted here, maybe came off like a jerk... I dunno.... but nobody was able or wllling to offer anything besides the TWO EXISTING ARTICLES on the web re: repairing this camera. Oh yeah, one of the articles is in French, btw.
So, the camera gets here, I pop in some new batteries, and it is FINE. Fast forward a little while, though, and the rangefinder starts going out of whack. Like, wayyyyy out of whack. I open it up as per the articles and do my impression of someone who should be trusted with sharp objects, let alone fine machinery, and by some miracle get the rangefinder SOLID.
Three days later, it's slipped again. Oh well.
So, now I've just taped over the rangefinder patch and use it in scale focus mode, mostly with a 21 and 28. Not ideal, but still fun and still manage to snag some keepers. The line about "walking wounded" is beautiful, btw.
Maybe someone will post some better instructions on basic CLE repairs, here's hoping.
Anyway, enjoy your camera, I certainly love mine.
