I seem to have damaged the aperture lever or its mechanism on my D7500. It doesn't move when a photo is taken and I get the 'Err' error message after a phot is taken at anything but fully open. If I hold it down slightly I can feel the spring tension reducing but there is no movement.
Tried cleaning contacts and poking the lever a bit so it seems it is time to go to a repair shop.
But I am in Saudi Arabia and wonder if the one authorised service centre here, which also repairs vacuums and toasters is my bet bet. Anyone got a camera repaired in Saudi Arabia able to share their experiences ?
