HID digital ballast failure

Hey guys, not sure this is the right spot for this but...

I have a 600w digital HID ballast. Recently I went into my shop and realized that the light wasn't on. I checked the ballast and it was very hot to the touch. I quickly unplugged it and let it cool down.

After it had cooled, I plugged it back in. The bulb didn't fire, and upon closer inspection I noticed the fan wasn't working. I could hear something in the ballast clicking but I couldn't find the source. (I later replaced the fan with a new one but it didn't start up either.)

I checked the board for any signs of an explosion, but everything seems shiny, new, and unremarkable. No burning odor came from the ballast either.

The online shop I bought it from has apparently gone under, no way to contact the retailer and I cannot tell who made it because there are no identifiable (to me) features on the hardware itself.

My questions are these; is there any way I could do a diagnosis online to find out the problem? Is there a particular part of a digital ballast that fails first when it gets too hot?

Also, I am unable to remove the board from the housing entirely because the bridge rectifier has been cemented to the ballast housing by some white rubbery looking stuff. Is there a way to safely remove this and allow me to remove the board?

Thank you for your time, and I'm sorry if I haven't provided good enough info. I appreciate any help you could give me.
