ive tried for 1:30h and it hasnt moved a single degree...
i think i have to give up for the time being until i find some solution to get grip on the screw
Interestingly, what worked for me was a flathead screwdriver with a shorter blade length.
The long way to the trigger magnet is to remove the mirror box, which will help you get to know the T90 from the inside.
A shortcut is to loosen the four mirror box screws at the front and the two at the back. Then the mirror box can be pulled forward, and the magnet is accessible.
However, this is experimental, as it can cause problems with the motor clutch.
Another option is to remove the green circuit board with the DC/DC converter (two screws, solder connections), which will give you direct access to the magnet's screw.
It should also be sufficient to loosen just the two screws.
See PM
We control the T90, not the other way around
Cant, its locked until i am at 20 posts "due to spam accounts" unfortunately

Great, congratulations!
So it worked without desoldering just loosening the two screws of the DC/DC converter board.
I would thoroughly clean all contact surfaces; the part inside the camera looks a bit cloudy. Try using benzine or isopropanol on a cotton swab, etc.
Can you use a magnifying glass to look at the coil (arrow) to see if there are any wires sticking out from the winding?
Might sound stupid but i used nail polish remover from the 100 Yen store and this is the result:

I was confused by this too but it was just some piece of plastic stuck to the tape, not the coil itself.
From this perspective:
- The silver screw is on the outermost side, top right.
- The longer screw is in the middle, top (hidden).
- The remaining screws should be identical. One is in the middle, bottom (hidden), two are on the outermost side, left, and the last one is underneath the silver screw.
Ok perfect, then I assumed correctly!
The girl is alive and well after essentialy being sold for parts
When I look at the complexity of film cameras from the 80's and 90's its like looking at a moon rocket. The scale of the suppliers that made all the pieces, etc, etc. Simply amazing.
If the sticky shutter occurs (black marks on the rear shutter curtain) there is also a shortcut:
Canon T90: Advanced cleaning of stuck shutter blades
Sticky shutter at EOS Nano Burger gives in „Manage Your EOS Camera’s Sticky Shutter“ https://www.instructables.com/Manage-Your-EOS-Cameras-Sticky-Shutter/ a guide on how to clean stuck shutter blades in a Canon EOS. The reason for the sticking is a small damper under the vertically running...www.photrio.com
The long (and thorough) way is to disassemble and clean the shutter. Something for a rainy weekend
Have fun with the T90!
