okay, so if they're not coded, and my new 'donor' board yields no results, then it means its a duff?
hmm.. I'm still trying to work out which mcd/brightness LEDs I should go for..so many to choose from - apparatnlty I need a light measuring device to figure out what brightness the existing ones are!
Shame, because if I knew, it would be a simple case of go in and order them
frustrated!
