I have been looking around to find a solution to my problem. I have not been able to find any information on any Canon camera that has been of any use. I'm asking here to see if anyone can give some ideas as to my problem. I am also very new to photography. I have only been shooting film for the last month on my Minolta X 700 and now this Canon Rebel 2000. So please be nice! My pop up flash will not fire. It pops up just fine in the auto modes, and when I push the flash button when in the "creative" modes. It just will not fire. When the flash pops up in the auto modes, I hear a slight repeating clicking noise as it tries to fire the flash quickly for the auto focus. I can also hear a slight whine that peters off quickly. The whining comes back if I push the flash down then pop it back up. Then it just goes away a few seconds later. This seems to be saying the charge circuit is working? Right? But, I know for sure that this problem is not the micro switch in the hot shoe. I can freely move the switch and push it down which makes the camera flash will not pop up. I have also used plenty of electrical contact cleaner in there so that plenty should have got in there. I used a q-tip and was sparing of course! I'm leaning on the flash tube being bad but, I am unable to test further right now, and I don't know how to disassemble to camera to check this or replace it! An external flash will work, and I have a nice Yongnuo YN600EX-RT coming soon to replace my old Vivitar 2800. Hoping this flash works in the E-TTL mode. Can't find anything on that either! Off track so, let me know your thoughts and how I might be able to test further or repair it. I bought the camera only recently so I am not too familiar with everything, but I do have the manual and have shot a few rolls though it. I currently have a roll of B&W in the camera so I won't be making any test shots, at least until the roll is used. However, my few rolls I have shot through this camera have turned out nice! At least as far as I can tell on the negatives, need to get a scanner to really see!
