Default Re: Leitch Studio Clock Problem

I know nothing about clocks, but a few common sense (I think) observations. Assuming it is similar to the one in Brunel's link, that electrolytic capacitor looks like the ones fitted in early 1970's hybrid Grundig TV sets, so change it. I would also run your soldering iron on every one of the leads of the ribbon cable It is easy to get difficult to spot dry joints.
There are three stepper motors shown, so with the clock disconnected from mains (after doing a reset, whatever that is), try with an AA cell with wires connected to find if you can get one of the steppers to move. Whichever one is not where the reset should have put it, step it thro until it is in correct position.
I have not done much with steppers, but I did find that by touching and removing on the correct pins it the correct order, you can make them go wherever you wish.
Cheers, Les.
