Galaxy Ballast Question

[dsaundry]

So I come home tonight and I notice half my tank is darker than normal, so I see that one side isn't working, so I change the bulb and nothing, still out. My galaxy ballast is the dual style so I swap the plugs and the side that was out lights up and the side than was on is dark. So my question is, in my 2yr old ballast repairable or is it dead? I tried the reset button too.... I got the ballast from J+L but I haven't the faintest idea where the receipt is, it got scattered with the reno's on the house.
