Repair flash hot shoe Canon 90 - can anyone help?

Araldite 2 part glue will hold it, try to apply a bead into the corners of the camera body and then push the plate in, this should keep the glue out of the holes and inner body.

Becareful not to glue the pressure switch.

You may have loose screws in the camera body, the contacts may not be connected internally anymore / or damaged.

Edit, see my post below, screws are needed.

Superglue?

Looks like the contacts will be ok.

Clean it with isopropyl alcohol to remove grease & glue it is my suggestion.

Thank you both - have you ever seen this work?
 
Remove the thin piece of metal on the shoe that has come off, there's probably screws or screw holes under it.
Just lift the one end up and it will slide off.

Edit: I would not glue it, it won't hold !

From a quick google, Canon use M1.7 x 3.7mm screws from the top under the spring plate.

Do you have screws below the plate? As it appears to be laying flat on the camera body I'm assuming their missing?
 
As above, it screws in place, and there’s a spring loaded pressure switch that might be missing too.

In short, it’s a simple fix, and there’ll be instructions on the internet somewhere, note that hotshoe isn’t unique to that camera, the design is ancient.

Edit: 2nd look, the switch looks intact, you just need the screws.

As @Sangoma has suggested, I think you'll need countersink screws as the plate is thin.

Hope you can find something.

Could be worth asking wex/fixation or a local camera repair store, they may have and sell you a few spare parts. (PC repair shop or model shop may be able to help).

The info I posted above was from a canon repair sheet but not a 90D, it was 5D III (but can't find it now).

I would have thought that any one who repairs cameras would give you the screws :)

The big question is though, how did they escape? They may just come loose, possibly over time, or maybe they had been out before for some reason, but they should still be captive under the thin plate.

No idea I took some photos with the camera I think Saturday using the flash then yesterday I used it without the flash. (I think I left the flash at home but I can't say, today I went to put the flash back on and found the problem).

Are you sure that it is true?
I read somewhere else

for many, many years Canon did it the other way with screws going downwards & held by either a plate below, or directly into plastic. I think they had only the odd problem of screws working loose and was easily fixable by users - until the 90D came along where they thought in their infinite wisdom it was better to have screws going upwards. It will need the top plate to be removed to resolve.

No im not ‘sure’, and the above seems to explain why it fell off and there’s no screws to be seen.

Looks like it’s not a diy fix if that’s the case.
 
If you rotate it or shake it (gently) is there any hint of screws rolling inside.
They could short something out eventually if you went along the lines of more cosmetic 'fix' of gluing it in place.
You could get an L bracket or frame to hold items that didn't need hot shoe.

Look at the plate that fell off, the four holes will have threads in if the screws are fitted from within the camera.

unfortunately it does indeed look like it needs to be opened up.

specialist glue actually wouldn't be a such terrible budget option if all you want to attach is a small and light trigger such as the new godox X3. That's presuming proper job is expensive, camera is cheap and you have no intention of mounting a full expensive and heavy speedlite.

I just use canon speedlite at the moment I haven't looked for quotes yet.
 
I don't think glueing is an option at all. it would decrease the resale value by more than the cost of a repair (I don't see it being more than an hour to remove the rear and front covers, then the top cover and fit new screws)

It will work loose over time, and as mentioned the loose screws may well short something out and permanently damage the camera.

You may not hear the screws rattle, as Canons usually have ribbon cables along the inside of the top (which would have to be removed to replace the screws) and the screws may be lodged behind these. It may also be possible for them to migrate down the front or rear covers, which you don't want, especially the back with the main boards.

If you do it yourself, the most difficult part will accessing the screws once you have the top off if they are hidden by ribbon cables, as quite often the ribbon cable is one part right across the camera between the controls/display etc, so you might have to remove more than you had hoped to get to the screws.
A touch of Loctite should prevent it happening again.

I have never taken a 90 apart so just pointing out possibilities seen on other models.

I think one thing is certain though, if you want to keep the camera, the screws need to be located and removed from where they are, you will never know if or when they may cause further damage.

Thank you I will look at a repair, very annoying to be honest if it weren't for two software benefits
focus stacking
the ability to have shutter speeds of less than 30 seconds the 7D MKII would be 100% better than the 90D
