How to open case to perform tests

I have the same problem as indicated below in an August 2005 post. I've removed all screws and opened flash head partially. The side with the dial is free. However the other side acts like there is still a fastener holding it together, perhaps under the silver disk. I'm afrade to force it for fear of breaking something. How do you get into the case to perform the below tests? The flash hasn't been used in many years and I'm sure the problem is a corroded contact inside. The hot shoe has 230v but as mentioned below, no trigger will fire the flash and discharge the capacitor. Thanks in advaance for your help. rws138 ************************* Symptoms: energy storage capacitor charges as indicated by the audible inverter whine changing frequency increasing in pitch until ready light comes on but pressing shutter release or manual test button has no effect..? Test for voltage on the trigger capacitor and continuity of the trigger transformer windings. Confirm that the energy storage capacitor is indeed fully charged with a voltmeter. **********************

Re: How to open case to perform tests

Remove the metal circle oposite to dial (it's glued). Under the circle you will find a metal clip connecting halfs of the flash - pull it out. Flash is ready to open.

Cannot open case to install batteries. Pushing door in direction of arrow. Is there something else?

I was able to get it open by putting my finger on the battery door back toward the screw and pushing it down and forward until it popped open. I worked for hours trying to get it open. I found a video on uTube that gave an opening review of the camera and I saw how he opened it. Hope this helps.

Zoom--mm blinking and can't change mode

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.

Sigma EF-430ST not working

This indictates one of 2 condition.
1. Batteries Flat
2. Information Fault.

More than likely the second is your issue.

if you here a whirring sound when the flash starts then your fault is possibly that the inner head in the flash can not move in it chamber to adjust for the focal length of the lens.

You need to remove the 10 screws (5 each side on the head) 1 is located at the front and 4 under the plastic cover at the swivel point of the flash. These are covers are held in by twin sided tape and can be pulled off.

Now in front of the circuit board is a motor and gear - just in front f this is the flash tuble and the chanber - click the tuble back into the chamber and ensure it moves freely.

You can check that all is working now by installing the batteries and turning the unit on - should settle at 28.

Once working reassemble and all should be fine.

Broken flat ribbon cable on SD 28 flash

Hello, after breaking mine this morning I was able to fix the flash so It can fire from the hotshoe.

Any automatic TTL features will still not work however atleast you will be able too fire in auto, and manual modes.

I simply opened the flash by taking off the hotshoe, and then swiveling the flash head 90 degrees to expose the four screws there. You need only remove the two screws from the front side of the unit.

Open the battery door and gently pull away the front case (Be careful there are several delicate ribbon cables that you do not want to snap. From here you can either unscrew all the ribon cables to free yourself room to solder or try and dodge them.

You should now be able to see the rear side of the PC sync socket. There is a blue wire that joins the outer edge of the socket - this is ground. Solder onto this point and join onto the top left circle of the PCB board of the hotshoe. (Opposite corner from where the ribbon cable attatches) There are copper circles exposed on the pcb for easy soldering.

Next, return to the rear of the PC sync socket and note the orange wire coming from the centre pin. Solder a wire to this point, and then down to the hotshoe PCB and to the circle that joins to the centre pin of the hotshoe. (Trace the circuit paths)

Sorry I did this about 30mins ago and I'm remembering this out of my head.

 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
