Sometimes bad caps show a lifting or rounding of the top of the cap, sometimes this top will split from heat and pressure and sometimes it will not show any sign of damage but will be dry inside and its capacitance value will drop to a very low value. Replace the big power supply caps and test again. Get the same size, value and voltage rating. You can go higher on voltage rating and a bit on value. Getting a similar size or something that will fit in the same space is important also.

This usually indicate a power supply rail, failure, and or a main amplifier has "Blown". You need to take this unit into a JBL repair shop, contact a local or head office of JBL, and ask them for a referral to an authorised service center. When in face to face contact here, ask them only and first off for a "Quote" as to the prospective repair costings and go from there?

SOURCE: Describe your Venue SUB10 Subwoofer

You can remove the screw near the volume knob and the screw near the on/off switch - then slide out the amp remove the black and white wire - then check the fuse - if its blown look for we repair amps - ebay - if its good then it probably still needs work - it should turn red when plugged in and no signal and green when signal is present - which means amp is on.

First try to find the source of your problem. The easiest way would be to try your sub with a different audio source to see if the problem still occurs but is sounds more like there's a problem with the receiver.
