Wasted too much time on A630 whose shutter seems to have become stuck in recent years. Black screen, black photos. Play / Rec repeatedly, opening battery door during long exposure repeatedly did not get it unstuck, tapping around on the lens more or less mildly with a pencil while doing the above cycles didn't do anything. Other ideas?
FWIW, if you want to hammer on the shutter actuator, you could repeatedly call OpenMechaShutterEvent and CloseMechaShutterEvent eventprocs. You must call MechaRegisterEventProcedure first to register them.
- Failed CCD. Take a picture (preferably DNG) and look at the grain. If there is normal grain, the CCD is probably OK.- Broken shutter flex cable (it's in the lens, difficult to repair).- Or, it could be that the shutter is just jammed a bit more.
Thank you. Well, why not. I recall having trouble in going to Rec mode from CHDKPTP the other day.
How would I best do this? In a simple loop as a lua script with some degree of sleep in between?
on 10> =wait=10 for i=1,10 do call_event_proc('CloseMechaShutter') sleep(wait) call_event_proc('OpenMechaShutter') sleep(wait) end
Code: [Select]on 10> =wait=10 for i=1,10 do call_event_proc('CloseMechaShutter') sleep(wait) call_event_proc('OpenMechaShutter') sleep(wait) end
--[[@title Cycle@chdk_version 1.3--]]call_event_proc("MechaRegisterEventProcedure")wait=10 for i=1,1000do call_event_proc('CloseMechaShutter') sleep(wait) call_event_proc('OpenMechaShutter') sleep(wait)end
It runs, nothing happens. Did I miss anything?
Note the eventproc names are slightly different on newer cameras, the ones I posted earlier were for A630.
call_event_proc('CloseMechaShutterEvent') sleep(wait) call_event_proc('OpenMechaShutterEvent') sleep(wait)
It's probably a long shot, but if it's stuck from sitting for a long time, I could imagine rapidly cycling it might free it up. You could also try whacking the camera while the script is trying to cycle the shutter.
