SOURCE: jbl PB12 powered sub woofer problem

These subs have had many problems, all associated with the amplifier section. PB 12's with an "M" as part of the ser. no. were assembled in Mexico and these are the ones with the amp problems. JBL fixed mine and sent it back no charge, BUT it cost me nearly $100 to send it to them in the first place. I have another one that has had no problems at all. Try sending it back for repair. At best you'll get a rebuilt unit back, at worst a substantial discount from the company for a new sub.

I had the same problem...replaced the C42 capacitor with one that I got from RS...fixed everything and all is well again. I only have moderate soldering skills, too, so if I can do it, so can you

More likely to be the Class D power amp module, but you should look through the service manual to make sure all the parts are installed correctly. My PB10 AMP module went out and you cannot get one anymore.

JBL PB12 will have loud thump or pop!


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.

Describe your Venue SUB10 Subwoofer Problem: The subwoofer won't turn on at all. The red light doesn't even come on. Could it be the fuse in the subwoofer? If so, where is the fuse located?


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.

Light stays red, will not switch to green. I hear no sound from the subwoofer


Red Light Constant On - Means the Amp Is Not Turning On - Signal Problem or Most Likely Burnt / Non Working Components - There Is A Guy On Ebay Who Repairs these amps.

PB10 Loud Hum and Crackle- LED Lights mixed Red/Green


Hello, Jesse. I doubt I can help, but there is at least one SIMPLE thing you can try - with maybe a 10% chance it wil return your unit to normal: Unplug the unit for 30 seconds, then plug it back in to a DIFFERENT outlet. Oh, yes - there are NO fuses or other "reset" devices. I'm sorry I couldn't offer you more help.
