Re: "the hunting sound came out with only displaying ZOOM A and TTL indication"

That has nothing to do with the battery, that is a blown capacitor on the flash board.

You need to have the flash assembly replaced.

Dear FixYa Customer,

Is the following your unit :

Please list your CANON UNIT MAKE & MODEL #.


STATES: "This Model JESSOPS Flash is NOT Compatible with the CANON EOS 50D!

I could find no technical assistance or phone number at the JESSOPS Site but you can e-mail them @

if you have a question about a product repair and it will be sent to their service department! I would do this since it may be a simple problem or an inexpensive repair!

Hope this is helpful.

Good Luck!

    Dear FixYa Customer gman 265,

    According to FixYas' Solution #1 by "ginko" you have a blown capacitor on the flash board necessitating replacement of the whole flash assembly!

    If I were you I'd either
    1) Continue to ask FixYa how to remove the flash assembly, buy replacement parts and install a new one


    2) Email Jessops again asking for an estimate to repair your flash for you in which case you should include all the relevant info Model Make Part Needed. I believe they will respond faster if you make them believe you want them to repair it for you and they will probably confirm the problem if you just give them the codes again....I understand you may have already asked them for a repair estimate so you may want to try telling them you definitely want to have it repaired but watch out they may want you to send it to them before giving you an estimate.

    Sorry to hear it wasn't just the batteries!

I have also suffered from this problem with Jessops flashes on various Canon cameras (even EOS 5N film camera) with my current Canon 40d sometimes the Flash symbol disappears from the view finder display. As I have two identical Jessops 320AFCs I believe it is to do with battery power. These guns will only work reliably with Duracell batteries or equivalent they soon lose the charge otherwise, they will not work at all with re-chargeables and only for a short while with standard AAs.

Hey guys. I use my old vivitar 728AFC flashgun on my canon 550d (T2i). the flash works but does not communicate fully with the camera, however my problem is; when set my camera ss higher than 1/200 it...

Hi, the flash in question will not work in TTL mode even though it has contacts on the bottom that may indicate that it could...... so it will work in auto or manual mode but not adjust itself. All adjustments will have to be made manually.

Broken hotshoe repiar problem

It's a known weak point on that model and is typical of ANY similar large, heavy flashgun which mounts via a hotshoe mount which was never designed for such loads.

Unfortunately, the most common type of break cannot be glued or repaired in any neat fashion, but if the wiring is intact a very rough looking but functional repair can be adapted by fastening external metal repair plates using epoxy resin and very short screws. The unit looks dreadful afterwards, and has zero resale value but it usually works and if done correctly the repair lasts the lifetime of the unit.

If you want a neat repair, then the only option is via the factory (often they just dispose of your broken one and send out another new unit). In the camera club which I belong to some members have found it's more cost-effective to sell the broken unit as spares or repairs on an auction website and to then put the funds towards purchase of a more suitable model (either a smaller, lighter, less vulnerable unit, or a proper off-camera hammerhead type unit like all traditional Metz models). One other member found that his credit card gave him accidental damage cover on purchases for up to ninety days (yours is brand new, so worth checking) and another found that her flashgun (not a Metz, but a similar bad design) was covered by her household contents accidental damage policy, but she had to pay the first £90 of the claim.

In case you're wondering, the "bad design" is an intentional compromise. It's simply preferable for the flashgun to break rather than for it to rip the top of your camera off. That's a major disadvantage with the repair option which I mentioned: further knocks simply mean that something more vital gets broken.

Good luck with whatever you choose to do, please take a moment to rate my answer.
