Polk sb9000iht fell from wall all speakers work just can't change volume with or without remote

If it fell and it was working before it fell it therefore seems likely that there is some mechanical damage inside. It may be as simple as a connector having fallen off. Open it and inspect for damage, check all connectors, look for any cracked boards.

An i get the diagram for the ON OFF switch and volume control? mine is damaged i like to fix it

-"Can i get the diagram for the ON OFF switch and volume control?". I built mine based on a schematic generated by tracing the printed circuit board of a working unit. Some component values are non-standard but I just used the nearest standard values. The ON/OFF switch was also replaced by a toggle switch because the original is an integral part of the volume control. The 9-pin mini DIN connector presented the greatest hurdle in my part of the world but got lucky cannibalizing a discarded Strobe Pro scanner. The completed unit worked as charm. The schematic can be found here:

nothing is wrong with the woofer the connect is broken at the strain relief and the cable needs to be replaced.
You can replace the connector if you know the pinouts. You will need the connector and the schematic.
you may be able to find the pin outs configuration here.
As for the connector this may take a search online.

I had the same problem and found the root cause to be the RF speaker connector at the back of the subwoofer. The male and female connectors are OK. It is the 5 male pins inside the connector and the way they connect to the female holes that is the problem. Wiggle the RF speker connector as you move it in and out until you get 100% of audio voilume back. Once you get it back, do not move the connector. Have not found a permanent solution to date beyond this.

Broken volume and tone remote cord for the SoundSource 3200 Seies


I just need a new connector cord as described. I was hoping I could buy a new one.

But it looks like I will have to take it to an electrical fix it shop somewhere to see if they can fix the pin connector.

Thank you.

Creative Inspire 5300 Volume Control broken!

For those searching the answer "How to replace/repair Creative Inspire 5300 volume control":

Its simple : looking at the back of the suboofer, the pins are as follows from top right, clockwise : LED VDD , Balance pot middle leg, GND, pots + legs, Volume pot middle leg, on switch input. Connect one pots ends to GND and the other ends to pots +, connect a switch on GND and on switch input, anode of led to LED VDD, cathode to GND (there is a 1,8k resistor inside so no external resistor needed)

No sound in my computer and i can't figure out why

Check to see if you have the mute ticked in the volume control, your laptop may also have a volume control knob that needs turning up.
Also check the sound level is not set to minimum.
Connect headphones to the sound out connector and see if you can hear and sounds.
Open the Control Panel, Click on Sounds & Audio Device Properties, you can check on all the sounds and audio device etc.

Dell HK 395 Speaker System - Need Circuit Diagram Download

1.  Check the orange multi-pin connector the sufwoofer for a broken or bent pin.  If there is a broken pin you can bypass it by cutting open the cable jacket and tap onto the affected wire with a 6 inch or so jumper, and then attach a jumper to the appropriate point inside the subwoofer.  Pass the subwoofer jumper out of the case (drill a small hole) and connect it to the jumper you added to the cable.

2.  Try wiggling and rapidly rotating the volume control.   There are reports this control may become a problem as it ages.

3. I haven't been able to find a schematic.  My only recourse was to google the output amp and the 2 op-amp packages for data sheets.  They are readily on the internet.  Then I laboriously traced out the stereo paths.  I found that red and black fine tip felt pens were helpful in marking out the signal paths through the circuit boards.

Can't increase & decrease the volume

Double check your connections. Still not working fine. Remove the input jack connector and try to touch or hold the tip of the connector, also adjust the volume of the speaker, you should heard loudly the 60 hertz sound of your body signal. Otherwise you have a defective amplifier in the speaker system.
