I had my A-1 checked out by one place, they said it needed a full CLA, and I think from the talk that included replacing any circuit boards that needed it, but this was rather pricey overall. I took it to another place and they said it was most likely the circuit boards, and suggested it wasn't worth the effort to find replacement parts. So, how hard is it to find good working (i.e. not take a gamble by canibalizing another camera and have IT fail from old age too) circuit boards for a Canon A-1? Everything else on the camera is almost pristine. Great finish, great looks, works sweet, silent shutter, clean internals... Taking off the bottom plate and manually tripping the shutter works, and it follows the light meter and shutter speed settings, etc... There's just a faint electronic noise and the meter LEDs go dark when you press the shutter button. What's an average (ballpark please) that replacing the upper housing circuits might cost? Can I save a chunk of change avoiding a full CLA if I only need this part? I kid you not, almost everything on this A-1 body is primo condition. Only down sides are the seals have started going and the button won't trip the shutter. If I can fix it without losing any more, that's good. If I'm sinking money into a failing venture, I'll cut bait and find a working model for less than I've already spent on this.
