Flash Bang Wallop!

The dreaded happened – I forgot to lock the 580EXii in place! With tripod and camera in one hand and large equipment bag in the other, there was nothing I could do but watch in perfect slow motion, as it bounced onto the tiled church floor. Luckily the only thing damaged was the diffuser panel.
That was two months ago and it’s been bugging me ever since to get it fixed. I seldom used the panel as the light’s too harsh for most situations, so there was no real need to get it replaced, but being a bit of a perfectionist I decided to get it repaired.
I managed to source the diffuser without difficulty but couldn’t get anything other than text info on the disassembly of the unit, so if you’re here because you’ve suffered the same fate, I hope this guide helps you out.
Word of caution: Remove the batteries. Even with the batteries removed the capacitor can still give you a nasty shock so it would be safer to discharge it first. I managed to avoid one but be warned! Remember that opening the unit will invalidate you warranty and by carrying out any repairs on the unit, you do so at your own risk.
1: New diffuser panel top right. Old diffuser panel with broken lug, bottom left and the white catch light card on the right.
2: Diffuser panel comes complete with hinge
3: Undo the two small screws from the rear of the unit using a watchmakers screwdriver.
4: Gently lever off the rubber seal using a flat screwdriver. The seal on either side is held by a tacky glue which was strong enough to reseal on reassembly. Remove the 6x screws (3x on each side) being careful not to drop them.
5: Seals and screws 8x removed
6: Gently prise the two sides apart to reveal the flash tube housing. Using a small piece of Blu-tack on the end of the screwdriver remove the 2x screws holding the white housing.
7: A small ribbon cable is attached at the rear of the tube housing and care must be taken not exert any pressure.
8: By moving the tube housing slightly to the side a further 4x screws can be found: see bottom left of the picture below. When they have been removed the diffuser cover will fall free revealing the diffuser panel holder.
9: The hinge can now be removed without any difficulty.
10: The new panel in place with the spring to the bottom. The white catch-light card has a small rectangle hole which aligns with the diffuser. Use a small piece of Blu-tack again to hold the catch-light to the diffuser – making sure to place the Blu-tack near to the rectangle hole so it can be removed easily after full assembly.
Note: The white catch-light has a slight bevel which matches the casing of the unit and thus should be aligned to match.
11: Assembly is a straight forward reversal of the disassemble process, nothing difficult. Use the good old Blu-tack to stick the screws to the driver, screw them in and the jobs done!
12: Load the batteries and test.
13: Looking healthy!!
Hope this helps
