Sorry about your tuner but don't despair; it's actually a straight forward DIY fix that I've done before a few times.
The easiest solution (which might sound crazy) is if you can, simply superglue the ends of the broken string together and then refit it. The only challenging part is to get the tuner display to match up with the frequency that's tuned in, but in most cases, the display indicator, being attached directly to the string via friction, can be adjusted easily.
If the old cable is shot and that won't work... Dental floss.
