Hello, I recently bought a Canon 814 XL-s that seems to be in mint condition externally. The only visible issue are the seals around the cartridge compartment that are ruined and falling off. But upon trying it out this problem arose:
Problem:
The film speed dial works erratically. Sometimes the motor will spin slow, sometimes medium, sometimes fast (about 0.5, 1.15 and 1.5 rounds per sec) independently of where the dial is pointing, but changing if I push it around by shifting it or pressing it lightly. The Slow-mo button always works, instead.
I still have to try other functionalities such as fades, preset bursts and changing the shutter angle.
I'm guessing it's just a problem with the selector's contacts... I've heard these are not so easy to reach, but then perhaps a little contact cleaner might be enough. I've only opened some Nizos, this seems a little more complex, and I found nothing online... Any ideas on how to reach these contacts, or about what else it could be? Thanks!
