Make sure all of your cables are seated well; this can come from poor shielding of low-level audio cables. If all seems in order, then the power supply for the subwoofer has poor filtering that can come from a failing electrolytic capacitor.
If you plan on DIY service, here is a link to the manual:

It is said to be 60 pages long.

JBL pb 10 sub keeps going into standby mode


Did the same fix as Bratcop on my PB10 with the 7.2 amp board. Replaced C42 and it seemed to fix the issue of rapidly switching in and out of standby mode.

JBL-SUB135S please i need User Manual


As it is also sold as part of this system, Cinema ProPack 600, this manual should suffice.

http://www.jbl.com/resources/Brands/jbl/Products/ProductRelatedDocuments/en-US/OwnersManual/JBL%20CPP600%20OM%20(final).pdf

Page 37 gets into it. That's all there is to know.

There's not a lot going on in a vanilla self-powered sub. You seen one, you've seen them all.

Jamo Sub300. No power. No lights


Well it would void the warrantee, but you can take the back panel off and the power supply will only have two leads (3 if grounded) in from the plug, and out to the crossover. It sounds as if you are correct that the power supply is bad.
