Question about Canon Speedlite 550EX TTL Flash
When the flash is in normal position, the info on the LCD flashes. When the flash is at an angle, it stops. How can I get the display to stop flashing in the normal position?
I know you probably have already fixed the problem, but in case you didn't, or just to help others with the same problem:
This morning I connected my 550 EX to my camera and had the same issue with the info on the LCD flashing incessantly. Turned out to be the diffuser on top of the flash head, the one you pull out, then down over the flash to soften the light. If the diffuser is pulled out even two millimeters from its resting position, the LCD won't stop flashing! Just push it back in, and voila!
hope this can be of help

I took what I thought was a bad flash to our local Canon Store. Flash facing forward it worked normal. If you tilted it on an angle there is no camera to flash control.The two don't talk ! The flash works but doesn't show the ZOOM range or fstop.If you pull the defuser out the LCD display starts flashing like there is a problem. But guess what ? All this is normal. They took down a brand new Canon EX 580 II and it does the same thing. I thought my flash was bad,but found out they all do this. So, best part.Not broken and working normally.

It is much simple than that. The 550 has a macro position, slightly below the front position. You just push the head all the way down, holding the button. The release the button and push it up, lightly. It will go up and make a "click". It is now in the front position and the LCD stops blinking.
If it is not clear, check the manual - it's there.

This is either a problem with a damaged cable, switch or connector in the region of the hinge/pivot of the unit. If you can see how to take it apart yourself, then it shouldn't be too hard to identify the cable or switch or connector in question (post a photo if you struggle) - you should be able to see if you can fix it fairly easily. if you can't figure out how to open it or don't fancy trying then any camera shop should be able to do this pretty quickly - just don't let them charge too much - it will only take much time if they have to send away for a new part - else is probably an hours work or so at most. If you decide to try yourself and need guidance please don't hesitate to post again or call on the live chat link. I am sure it should be fixable and worth fixing. Hope this helps :)
