So when I get home, I'm going to first clean the sensor
Secondly, in that video, the mirror rises and the shutter curtain falls backwards, correct? Couldn't I just poke that shutter lightly to unjam it if the cleaning doesn't work?
Does the fact that this is a CMOS and not a CCD make any difference?
Also wanted to thank everyone for all the help and how kind everyone is.
Never, never, never, never, never, never, touch the shutter, and especially...
Never, never, never, never, never, never, never, never, never, never, never, poke the shutter, you will break it. They don't fall back they drop down, and reset (move up) when the mirror drops back down.
CCD/CMOS doesn't matter, cleaning the sensor won't help, running it though sensor cleaning mode may help unstick/reset the shutter though.
EDIT: If you can't physically see the sensor, one or both of you shutter curtains is not opening. If you can see the sensor, then odds are your shutter is fine, but try shooting to see if this reset/realigned the shutter.
If its worse than the shutter, buy another off craigslist or
ebay, that model is cheap enough, or better yet get a sturdier model either a single or double digit D.
