Re: jbl psw1000 no power

Have you checked all fuses. There might be 2 - one for the input and one specifically for the amp section...

Check to see if the speaker is fried. Remove the grill then place your fingers as evenly as you can aa couple of inches away from the cone. Press gently and listen. There should be no scrating sounds at all. If you hear this, first try repositioning your fingers. If it persists your speaker is fried. This is caused by a few reasons. Amp failed and took speaker with it. Or a large signal was inputted which causes the amp to hold its max power for a longer period of time (amplified signal is no longer a sine wave but a sqare wave).

Otherwise, unless you know what you are doing with AC (house power) I don't suggest you go poking around-you need at least a volt meter to start testing

Is there a replacement amp for my jbl SCS180.6S subwoofer? I tested the speaker and it's fine. I also tested the output from the stereo and it is also fine. When the sub is turned on, there is a b

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.

Can`t power it up. Connections and fuse OK. Stopped working after switching off and would never switch back on. LED indicator light`s neither green nor red but simply off.

First, I have to commend you for having a really fine piece of equipment. Mission makes great products. Now down to business. Being where I am and not being next to your sub-woofer with test instruments and tools I'm going to be so basic as to almost be insulting. However, If I were there, I would be testing these things.
Normally, when one has a catastrophic failure. i.e. no power, and no indication of power present one starts with the power supply. And that starts at the power company.
1st Determine if there is power in the actual outlet that the unit is plugged into. I have found that when installing a sub-woofer on a two plug wall outlet, for example, it might be plugged into a plug intended for a floor lamp. and is turned on and off by a wall switch. Many residences have this feature. It is usually one of the two plugs in an outlet. So you have to test the actual physical outlet. If the outlet is off, check the light switches. If there is no power to the outlet, check the household circuit breaker.
Let's assume that everything works, so far.
The next thing to do is check the internal fuse with a meter. If you don't have one, pick up a multimeter from Radio Shack or Walmart for less than $20.00 or Harbor Freight for less than $7.00
If the fuse looks good but checks out bad (sometime happens) replace it with A FUSE OF THE SAME VALUE. DON'T STICK IN A PIECE OF ALUMINUM FOIL OR BYPASS THE FUNCTION AND PURPOSE OF THE FUSE. The fuse costs a dollar, at the most, the Sub-Woofer costs $800.00 at the most.
OK, so now you have either a working sub-woofer, or an elegant paper weight.
If it is still being a paper weight, contact mission to locate an authorized service company. This piece of equipment in not designed to be user servicable
Here is their link below,
I hope this helps,
Best Regards,

Loud buzzing from Kef PSW1000 Subwoofer

yes. A good idea. Kill power to the sub, then unplug and remove everything from the sub. go ahead and plug it in again and check for buzzzz.
That is test one. if you have buzz still, its the sub assembly. bad luck, but not impossible. If the buzz is gone its one of the signals to the sub. They can produce a buzzz without any signal coming from your stereo equipment. Replace the feed line, enjoy! BTW...Kef sure does sound clean. good choice.

Continous low level pulsing but no Base Response from JBL PSW1000

There is a huge discussion among audio enthusiast regarding subwoofer output and how you should connect your sub to your system. If sub preout is turned and on your amp/receiver and you are able to adjust the crossover frequency adjust your crossover frequency to highest setting, higher HZ number, so you don't double low pass filter your signal too much. If you can adjust crossover frequency on your receiver and your sub allows separate connection to by pass it's filter, use that instead.
There is a great article on Polk Audio website regarding Home Theater setup. You can use it as reference and tweak it to your taste.

If no warranty - remove amp and check sub to another amp to isolate speaker from internal amp. Either the amp blew a channel or subwoofer blew. JBL's are typically well built. Has this speaker often been pushed loud often?

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.
