btw I think it's 8 drivers, 1 driver for 2 clusters. And I am pretty sure that in both case it's driver failure .
An easy way to determine whether it's a bad driver or an open led is to plug a known working driver into the two clusters. Just unplug one that's working and plug the suspect clusters into it. If they light up, it's the drivers. If not, you have a diode out. I've had some experience repairing the very light you have and its almost always one of the leds burns and goes open circuit and usually in only one cluster. If you can't reflow solder a new led and resistor onto the board you can bypass the burnt led and get the rest of your leds on the cluster to light up. All of this applies if you have warranty problems and/or need to get it working asap.
