Your zoom motor is probably stuck. Remove the two screws on the front side of the tiltable head. Pry off the two tilt caps using a small flat head screwdriver (they are glued on). Remove the 4 screws found under each cap. Now you can separate the two sides of the head and take out the two lenses (remember exactly how the lenses were positioned). Try pushing the flash in or out (it should move with a little force). See if the flash now responds before reassembling.
Worked as a charm for me! I opened the housing and used a plastic rod on the edges to move the flasher a little. Suddenly it snapped and from then working perfectly! Thank you very much
Perfect. Worked for me too :-) Thanks a Bunch !!! Perfect instructions above. I can see how the mechanism would get mildly stuck sometimes. And then be unstuck manually. Probably happens to a few other people as well. Perfect instructions.
Perfect instructions. Worked like magic :-) Thanks a Bunch !!! I used my fingers to hold flash by edges carefully and pushed gently. Little more force at a time and it snapped. I can see how this might happen to a few people out there.
This solved my issue too, I have posted an illustrated step by step tutorial on my blog:http://wp.me/p2HrbR-2e

Hi,
This is probably the switch of the zoom head wich is broken.
Open the head carefully, and you'll might found the broken switch, this is connected to the PCB with only 2 wires.
It could also be the small sliding connector wich is not working properly.

I had the same problem with mine and it was the zoom mechanism was stuck, I've put together a detailed tutorial on how to fix it here: http://coatesandstain.com/how-to-repair-a-canon-430ex-speedlite-zoom-function-frozen/
My speed still saying zoom--mm.... what do I do? I have taken out the batteries and check all of the above

Did you press MODE or ZOOM button? Otherwise did you turn off and on the flash? It will stable when SLAVE is off. Try these please.
