Something is wrong

There is nan internal fuse right behind the board were you plug the power cable in. You have to split the cabinet to replace.

poor design, the amps that are screwed to the heat sink are below a transistor which is catching all the heat,heat rises and changes the bias of the transistor so high it causes runway in circuits that results into failure also the amplifiers are sealed with no air flow, this can't be good.Maybe if they put air vents or remove the cover to panel then the heat will have somewhere to go instead of just building up inside.If this problem is not fixed a replacement is going to fail too.good price bad design.

Didn't it come with a manual?

Of course it needs external electronics to provide sound sources, controls, bass management AND amplification for the other speakers. It's just a sub.

I had the same problem and fixed it by replacing the C37 capacitor (see service manual). It was a 47uF 16V eletrolitic capacitor. No external signals of problems, but it was defective according to the capacimeter. I replaced it because it was the part responsible to retain charge and keep the voltage up in the signal sensing circuit (a simple comparator). After the signal gets low or disapear, it would slowly discharge through a 10Mohm resistor (R121).
Replaced for a 47uF 25V eletrolitic capacitor.Everything went back to normal.
