I have a couple of T2's which are about the same. I had a similar thing happen to one of mine when I had a TC mounted. It took some fiddling with the aperture feeler in the camera body to get the shutter release to complete it''s cycle. Also it looks like your timer is set. Is it not counting down? That would cause the problem as well. I have not delved any deeper into my T2's other than re-mounting the battery well contacts so i can't help much more than that. Getting repaired would prbably cost more than finding another body. Good ones can be found for around $40-$80 US.
