P30 Fault, cann it be easily fixed

Hi
I was wondering if anyone on this forum nay be able to help me with a Pentax P30n fault. I'm wondering if it's a known fault?
I know a P30n can be picked up for less than twenty quid but so it's not worth getting it repaired but I've had this camera since the 90's, it was my first real camera (that I "borrowed" off my Dad as a teenager and still havn't given it back)So it would be nice to fix it if I can. I'm fairly confident with things like this.
It hasn't seen that much use really, I just push a few rolls of Tri-X at 1600 through it occasionally.
The last roll that went through started ok but half way through the shutter would not cock in a single advance of the film wind lever, some times it has to be crancked multiple times to cock the shutter. Which wastes a lot of film!
Any one know the fault or the cure?

Your help would be apriciated.

Sorry, not heard of that one but it sounds like a mechanical fault.

Only you can decide what it's worth to you to fix.
