You have the old style pads. They are notorious for burning out. Its the larger cluster leds on the blue channel that are really bad, they start to delaminate from the circuit and open the circuit so nothing works on that channel anymore.
The new pads a totally different, different leds, restistors and diodes all added to the new pads. They require new lens as well.
You can sometimes get the busted blue leds to light again by putting a little pressure on the top of the small led emitter. IT never last long though. I was able to get it to last for quite a while using a type of glue to reseal them but they ran hot enough that eventually that fails too.
Now if you contact coralvue and explain whats going on they will make the offer to replace all pads and lenses for roughly 120US. But they want you to ship it back to them. IF you can convince them that you can fix it yourself AND get them to ship to Canada they may just send you the parts.
I searched everywhere for the individual LEDs used on the old pads and guess what, they don't exist anymore.... why? Because they sucked.
I can send you my old pads where you may be able to heat the pad up and replace the individual led. But I would try to see what coralvue will do for you. They are usually pretty good with helping out their customers.
They gave me a great deal on parts for my three fixtures, after a few months of scabbing things together I emailed them and explained what was going on. I live on the border though so I never had to convince them to ship to Canada.
I was told that they really only warranty united states addresses, however I have been able to get around that with a bit of patience.
