My 430EX is making a buzzing noise then it flickers in between taking images. The images are still OK, but I can't tell if it's the flash or the camera which is new. 50D

The buzzing noise is normal for that model .. first it makes noise as it charges and maintains the capacitor then when it auto focuses ..
here is a discussion of your speedlite model and the buzzing it produces

The problem is with your IP (inverter / power) board. This is a pretty common issue, actually... one I see almost daily. The power board for your TV is part number 0500-0507-0260, but they're not available anymore... the sub part is 0500-0507-0260R.

Just got a Canon 7D. Attached my 430EX to the hot shoe and it won't fire. Tried new batteries and checked the contacts, and it still won't work. Put th 430EX back onto my Rebel XTI, where it has always...


Make sure you using flash grade batteries and not rechargables. try energiser ultra or litiums or duracelll plus but nothing else. if the charge light is not coming up then most likely batteries. I would take it to your local camera shot and test your 7d with one of thier 430 just to make sure the hotshoe didnt short out the flashgun

This could be early signs of imminent failure of a defective CCD imager. If so, Canon should fix this for you for free, including free shipping both ways. This is regardless of your camera's warranty status. Please check the following two links for more info:
