I think that when trying to force my seized front mech to shift, I may have done something to do the shifter. The problem seems to be that the bit that holds the ball end won't move around when attempting to shift. So it doesn't have the indexed clicks either and I think it's stuck in the "big ring" position. See a pic below that shows the ball end stuck in the part that won't move..

Can this be fixed somehow, anyone had the same problem?
At the minute I'm riding the bike 1x9 which isn't actually too bad but it'd be nice to get it all working as it should!
tiagra 4500? this happened to me. a small piece of plastic inside will have snapped off. you need to open the shifter remove the snapped bit and reassemble. It's not as difficult as people make out.
there is though a lack of guides available.
I followed a japanese guide and the use of google translate - shifter is as good as new now.
Shimano europe website might help.
You can take the assembly out of the shifter housing via a grub screw & pivot bolt, might give you more room to work (just watch out for the lever return spring)
You can't strip them much further though without killing it completely.
Has it possibly pulled the cable end past where it's meant to sit & gone further inside the shifter?
I've seen that a couple of times & it's do-able, just fiddly.

this shifter is the same constuction
Cheers! Will give me something to do on my days off this/next week 😀 Just how fiddly is it though? I'm not very good with really fiddly stuff, how much should an lbs charge to sort it?
It depends how long it takes.
I've done one in 5 minutes yet spent an hour on another.
Really is impossible to tell until you're working on it
