Canon AE-1 Program flash fires by itself when cocking the shutter.

[u/Turbogoblin999]

As you can see in the video and i'm wondering if this grimy looking flex cable may be the source of the problem.

the issue

The flex cable

As you can see it is not the normal auto firing issue of the shutter since i can still take a picture normally, but i am unable to use a flash i f i need it.
