E30 convertible roof top stuck in down position

[e30tron]

I have a top that will just not budge and unfold out of the down position.

it is an automatic , with disengaged motors.

I have been manually folding it down and unfolding it up for years no problem.

but now it just seems like it doesn’t want to unfold back up!

any ideas what might have happened or what I should be looking out for to get it back up ? Thanks

Lubed the hinges and that seemed to get it back up with a little force .
