I purchased a pair of the 12" 15 led smd strips with the 3m adhesive on ebay. they work great and look great (except even though they are supposedly ultra blue, they do not match the ultra blue led dome lights i have in) except for today when i noticed that the one only ahve the first set of 3 leds, and the third set of 3 leds lit up. leds 4 5 6, 10 11 12 13 14 and 15 were not lit up. Im assuming this is just a break in the wire somewhere. but does anyone know how i could go about investigating/fixing this?

Thanks!
