Default Help? SWA1801 Sub quit after 4 seconds

I moved and hadn't turned it on my Mackie SWA1801 powered 18" sub in maybe 3 years. As soon as I powered it on, the LED lights lit up and then there were some slight popping or weird static-y sounds for about 4 seconds and then the lights went off and you could tell it was no longer powered. I unplugged and plugged back in and I can't get her to power on again. I took off the back panel and checked the 3 fuses that I can see and they were all good. I don't see or smell anything that's burnt. The big black transistors(?) don't have domed tops (which would show need for replacement).

Any tips on getting this baby back to work?
I can attach pics if that'd help.

Popping noises are never good, I think you need to get it to a qualified technician this most likely is not something that will be a quick fix.
