JBL SUB160 has power, but no sound output

I have a JBL SUB160 subwoofer. I was playing around with moving it to a few new locations today. Every time I moved it,it worked fine. Then, on my last move I sat my Yamaha receiver on top of it (along with a few other components), turned it on... and nothing! I'm using the LFE input, but I also tried the high level inputs and still nothing. Do you think moving a receiver (a.k.a. big magnet!) caused my sub to stop working? The power light on the sub still comes on (green), but it acts like it is getting no input. If I turn the volume of the sub all the way up, I get nothing (no humming). I've ried about every combination of inputs (all confirmed working) to the sub, and nothing...

SOURCE: my magnet cracked on my jbl sub woofer can it be

You might be able to get the manufacturer to replace it. Sub woofer repair is possible and some manufactures do offer that service, you'll have to check with them though. There is one other thing to consider- does it still work? If so you might be in luck. The magnet is there for its magnetic feild not how it looks. So if the magnetic field is un-affected and the voice coil is in one piece and un-obstructed it should be just fine. If the field is slighty out of place or not as strong it will probably affect its performance though. Good luck.

SOURCE: JBL Subwoofer - Intermittent operation

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.

SOURCE: the fuse keeps burning out in my jbl sub 10, even

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.

No you can't! I should contact JBL for the location of the part. Transformers are safety parts and should only be replaced by the same part or those approved for use by the maker of the unit.

I have a set of two JBL Prx525 that I use in my local band. From the time we got them, they have emitted a hiss sound. The hiss is not present if no sound is being put through them, though. Say a keyboard...

The hiss is caused by the autooscillation of the internal amplifier. To fix that you will need to install some additional filtering capacitors on the power lines, a high frequency filter at both the input and the output of the amplifier (basically just a 100nF capacitor put in series with a 10ohm resistor between the in/out and the ground) and a new routing of the internal cables. Also check a ground loop on the cables.

I have a JBL subwoofer SUB135. When I turn it on it makes a popping noice. I am not sure what the problem is. It was recently moved when we put in hardword floors. What could be the problem, and how...

Are you sure this is new? That's a pretty common (granted annoying) trait of subwoofers. If it just makes a pop and then works fine, it's probably normal and caused by the capacitors in the power supply. If you're positive it's new, then you'll need a technician to look at the power supply. Did you change the wiring? Often subwoofers are "on" all the time and have a connection to trigger them when the reciever is turned on. That might reduce the pop rather than turning the power on and off every time...

Have you made sure the dock is compatible with the iPod version you have? If you are having to move the iPod around, this may be because the dock isn't built for the iPod you own.

It could also be a technical fault that the dock is loose. Take it/send it back to the shop and explain your problem.

JBL PB10 has lost power even though still plugged into wall, any suggestions?

Do you mean like the subs power lights dimming when playing it at volumes it once had no problem playing, or loss in sound, distortion?

Sleep mode

It will power off if the frequency range of the signal being sent to it is set too low, or the amplitude of the signal is too low as well.

Try increasing the subwoofer crossover frequency and/or increase the gain from the LFE/SUB of the receiver/preamp you have it connected to. Also make sure that in the setup menus of ALL of your components have an LFE channel enabled such as by selecting the output of source material of your DVD player for example, to output 5.1. Otherwise, it will not send a signal for the subwoofer to play, nor will it play the signal if the crossover frequency is set too low.

Example; the setting on your DVD player setup menu is set to two channel: result with only one exception, subwoofer will not play

Example; subwoofer/LFE level on receiver/preamp set to -10dB and/or subwoofer volume too low. Result: subwoofer will not play.

Example; subwoofer crossover point set at 35Hz. Source material playing sound at 30Hz and lower. Result: subwoofer will not play.
