A Quick Fix For Creative Inspire 4.1 4400 Speaker Volume Control Unit

I have a Creative Inspire 4.1 4400 multi-channel speaker system. The problem is that the power/volume control unit does not work any more. I searched their website and came to know that they don't sell any spare parts. I went to their service centre in S.P.Road and the person there said, "We don't have spare parts but you will need to get the entire system and we will send it to the company in Mumbai and then they will service it and send it back."


Well I felt it was a rip-off because they did not even bother to ask what the problem was and then there was no information regarding the process or the cost that might be incurred.


I contacted their service centre in Malleshwaram and the person there was kind and honest. He said that they don't have spares but they can check and get back. He took my phone number and promptly called me back in about an hours time. He said that they do have a spare but its from another broken unit and can be used. It will cost Rs.350. Hmmm.... Though it was not a fair price he was at least frank to keep informed everything about it.


Then my curiosity said why should you spend Rs.350 when we can take a look at it and try to figure out what is the problem. Well I was successful in solving the problem and felt like sharing the solution with everybody and hence writing this blog.


What you need is a 5 pin 10K Potentiometer which costs about Rs.20 (~50 US Cents), a soldering gun and soldering lead (paste) both of which I already had at home. Please note that this is a quick fix and not an elaborate solution. This solution works if you are sure that the problem is specifically isolated to the power/volume control unit. Please make sure that all the terminals are disconnected from electric connections before you start to do any of the below mentioned steps. Please double check and make sure that the power supply is off and disconnected as the speaker's power adapter output is AC.


When I opened the power/volume control unit, I saw the circuit board as shown in the following picture:








The board has a couple of numbers: MS0240A and 010128. It also has Copyright Creative Technology Ltd. 2001.


I prepared the circuit diagram to understand how it is built and to plan what can be done before diving into action. As a project manager, my experience tells me very clearly to plan properly before doing anything.






What I did was to cut the power/volume control unit cable and have the wires ready to connect to the 10K Pot. 


Connect the coloured wires as shown below and solder the terminals for a firm contact. That's all there is to it. 










Once complete, for your own safety, wrap the pot with an insulating tape.


Peace!!!

Hello!
Thank you for this guide, it's amazing!
I have a similar problem. Actually I got the speakers for free from freecycle but they didn't have the volume control so I have to make one myself. I have found the DIN plug required (to connect to the subwoofer) but could you please guide me with the pinouts? I mean, what is the purpose of every cable leaving the subwoofer? I can see in your photograph that they have different colours but which is which? :)
Thanks a lot!

Is this diagram valid? Do the pin numbers match the colours? Thank you! http://www.smarthomeusa.com/Products/LT0146/images/LT0146-Pin-Out-LT0146.jpg

I couldnt find a 5 pin 10K potentiometer anywhere in my town. However, a 3 pin one is available. Anyway I can fix it using those?

Ashwin said...

or is it possible to just join the wires such that it is always at max volume (i can adjust the volume in the computer)

@ Ashwin
Actually, it is a 3 pin pot (mono, linear). The other 2 pins on the bottom are for power, therefore you need to buy a pot WITH SWITCH. Then you'll have 5 pins.

hey, i want to know if there is any way of not using a potentiometer and permanently set it to full volume??

Raf Raf said...

Rajeshwar,
it's possible, BUT: The lowest volume you will habe will be pretty high (loud). At least it was on my PC.

I have a inspire m4500 speakers
but its volume controller is not working.
its actually working but unable to function because the 9pin steal thing connecting the volume controller to the subwoofer is damaged.... I tried fixing it but no one could do it around me.... I cut the wire.... And found there are only 3 wires from volume controller going to the subwoofer.... I couldn't understand. How 3 wires are connected via 9 pins!!!

fine I searched for a 9pin mini DIN cable but till now couldn't find it..... :-( plz help me out.ma speakers are dead since 3-4 months

Hola, hello

Could someone give me advice on a similar situation?

In my case I have the part, but the 6 pin miniDIN connector is missing.

I can buy a new mini DIN, but... can someone give advice on the color code? what color cables should go to what pins on the miniDIN ?

Thank you very much, gracias

I found a 10k 3 pin potentiometer.Is that ok if we change the order of the two wires red and white?

1st white
2nd yellow
3rd red

Hi. I am from Mumbai and have the exact same speaker system. In the past 4 years I have spent nearly 1k in fixing this volume controller! I am an extc engineer but very weak with circuits. My inclination is towards software.

I have a 6 pin pot that i got from the local store. couldn't find a 3 pin one. i was wondering if some standard loosely sold volume controller would work?

Hello,

Thanks for this.. I have a broken 9-PIN DIN Controller for my Creative I-Trigue 5600 sound system (there are 9 pins connected to the subwoofer), could you please advise on the Potentiator type which i need.

Any help on this matter would be appreciated, it won't matter if its full volume, as long as it works.

Hi, I know it's an old theme, but I hope to get the answer. How do you open the controller like is shown in picture 1 ? I put out some screws from the bottom, put out the bottom, but can't understand how to dissasemble the circuit board from the top? thank you for any help. could send message to my e-mail: adzius@gmail.com .
