Hi all, I recently decided to attempt to astromodify an old Canon 450D, adding in the Baader Astro-Conversion filter - I followed the modification procedure on Gary Honis' website and managed to swap the filters and reassemble the camera, however when it came to switching the camera back on I get no response. I've tried reseating and repositioning all ribbon cables that are unclipped during the process - including cleaning all contacts with isopropyl alcohol to make sure nothing is messing with the connection. I've lost count of the amount of times I've tried doing this, and even removed the rest of the body to make reseating ribbon cables I and J easier. I've tried with different batteries just incase, and have noticed that if the battery is left in and the camera is switched on, they do drain over time - so I expect the issue lies elsewhere. Has anyone had any experience with this, and if so I would love to hear any recommendations of what I should do next!
