Power issues: will not turn off or function

If your Pioneer SW-8 subwoofer is not powering on, there are a few things you can try to troubleshoot the issue:

1. Check the power cord: Make sure that the power cord is securely plugged into both the subwoofer and a working electrical outlet. If the power cord is loose, try unplugging it and plugging it back in.
2. Check the power switch: Make sure that the power switch on the back of the subwoofer is turned on.
3. Check the circuit breaker: The subwoofer may have a circuit breaker that has tripped. Check the circuit breaker on the back of the subwoofer to see if it has tripped. If it has, reset it by pushing the button back in.
4. Check the fuse: The subwoofer may have a blown fuse. Check the fuse on the back of the subwoofer to see if it has blown. If it has, replace it with a fuse of the same rating.
5. Check the auto power function: The subwoofer may have an auto power function that turns it off after a certain amount of time if there is no audio signal. Make sure that the audio source is playing and sending a signal to the subwoofer.

If none of these steps resolve the issue, there may be a problem with the amplifier or power supply in the subwoofer.

From set up manual Setting up the system takes no time at all. Connect the subwoofer to the main unit with the provided cable. The NXT speakers connect directly to the subwoofer with color-coded cables for left and right. An FM antenna is included and can be connected easily to the rear of the unit (the AM antenna is built in.) Finally, the subwoofer gets plugged into the wall for AC power and the unit can be powered up. If this takes you more than 5 minutes, call your Dad and ask for help, you're probably over-thinking it. There is no setup in terms of volume or bass management configuration as the sub handles all crossover functions as well as volume balancing between itself and the NXT speakers.

Logic card issue, get it repaired by a good technician. I too faced a similar situation

Got the exact same issue... can't find a solution anywhere.

If the system is connected properly and the main tuner power is on you will see the orange standby light on in the front of the main diamond shaped control unit. If that light is not on, you have not connected the system and power cables properly.

If the standby light is not lit, press the power on/off button in the middle of the rectangular processor/tuner to turn it off and unplug the main power cord from the main tuner/processor from the wall. Next, ensure that all of the power, video and audio cables from the diamond shaped control unit are properly connected to the large tuner/processor. Since you are there, check any other av in/out connections.

Now that you have checked and adjusted the cables between the controller and the tuner, plug the tuner back into the wall and push the power on button. Now check the standby light again on the diamond shaped controller unit.

Once that light is lit, press the silver, horizontal on button in the middle of the diamond shaped display unit, or the Power Standby/On button on your main remote control and you are operational.

same here. happened after moving residences

I have several of these units due to being a liquidation seller, and the MOST common problem is the subs not getting any power. Next is CD Player Dying, and 3rd, unit powering, but not sending info BACK to the sub.

In any case the issue with the subwoofer is rarely the fuses. It's further up the line. So far every unit we have checked the transformer was the culprit. If you are handy, by all means replace the transformer and you're better to go.

okay, this seems like either the fuse hase blown in the actual mains plug, or the mass fuse inside the device, it looks like this very small glass fuse, same size as an ordinary fuse, its just seethrough. see if you can get a replacement for it, you may need 2 open the unit to check if it has blown, it will be black or a "burnt" colour from inside! if you dont want to open it, take it to any electronics store, they are bound to check for you, but these fuses don't cost more that $1 or 50pence!

hope this helps

every thing is working the system and the subwoofer my problem is the center and surround speakers are not working
