As folk above have said, if it's within warranty period, odds are it'll be replaced even without a receipt - Silva are pretty good for this.
If you do need to buy a new one, I really don't think that you can go far wrong with the Type 4 - good selection of roamers, mm scale , long base for easy using establishing a bearing on longer legs and sits nicely in a mitted hand. Big enough for bezel to be used by mits as well.
Not the best for running / racing though.
If you do a lot of sighting / resection then type 54 is good too - but you'd need to be using it a LOT to justify the extra cost.
Most compasses from established companies are pretty good, but I'd avoid ones without roamers on the base - when the weather is crap, I'd rather not have to do maths to figure out distances from a mm scale!
Cheers,
