Blown Ballast

[Delphinus]

It's probably a safe bet the ballast is fried, sorry. Check with the manufacturer to see if they can be repaired.

At least in my experience it's probably bad news. I had an electronic ballast for a double-ended lamp that I was trying to DIY a fixture. Somehow one of the lamp leads contacted the fixture, which I had diligently grounded. That was that. I then read on the ballast some warning about the lamp leads were never to contact ground. Ooops. I opened up the ballast to see if it was repairable, and it probably would have been had the whole electronics board not been encased in epoxy. That was an almost $200 donation to my garbage can.

But, some electronic ballasts are repairable (I think). I think Icecap for example can repair their ballasts. I just had some cheap knock-off brand and as far as I know the manufacturer doesn't even exist anymore, so I was out of luck, but perhaps you have a chance still. Good luck.
