Is there an easy cure?
Depends on what the disease is. Can you get hold of another flash to debug if the flash or the camera is to blame? Did you test if the flash still works as an optical slave w/o repair?
Is it worth sending it in for repair?
Hardly, at least with the cps service prices around where I live. Look at the 430ex2 prices on ebay and decide.
It's a nice flash, but 430ex2 doesn't have rt capability, and you get "big" 600ex flash clones from 3rd party manufacturers very cheap these days. Unless you positively want a "little" flash w/o master capability, get a new one with warranty.
