Question about Creative Labs Gigaworks S750 Computer Speakers

3 Answers

Gigaworks S750 Hi- My Creative Gigaworks subwoofer won't power up. The green light just flashes and the control pod doesn't power up. I can't get any sound from the rest of the speakers, because the subwoofer contains the amplifier for the whole system. Please help. Thanks. Var

    I have a similar problem although my speakers are soldiering on with drastically reduced power. I switched on the unit using the rocker switch on the rear of the subwoofer unit. A loud crack came from inside followed by a white flash of light and that unmistakable smell of electronics that have fried. :( I unscrewed the back plate to see the damage which turned out to be a component on the power board, there was a black burn mark on the green board. I was shocked to see how messy and shoddy everything was on the PCBs. Obvious signs of hurried careless work - made me sad to see it. No wonder there are so many problems with this system. I have had two breakdowns. Waited four months for the first repair in Singapore at Creative HQ. I complained but they could not care less. The founder of Creative is a Singapore native and something of a local hero. It's a pity he gets all the manufacturing done in China on the cheap.

If you check the Creative forums there is a thread there where a few people have started to fix problems like this permanently and they have helped quite a few people fix their problems. I would only suggest checking it out if you have any electronics experience (soldering, and basic troubleshooting minimum). Otherwise I would send it back but keep in mind that this is one of a few common problems with the S750's and you are likely to have other problems in the future unless you take measures to fix the problem that creative has not.

I would also like to point out that your problem would be a short on one of the amp boards after the power regulators, very likely one of the STA575 amplifier ICs. Those are not easy to find but it is possible to find replacements.

There isn't much you can do I'm afraid. If you were still in warranty Creative would replace the sub.. but as I found 2 months out of warranty, they really didn't want to know. Their solution was buy a brand new system. This problem of the subs "blowing up" can happen from the moment you first turn it on to a few years down the line. My system had never been over half volume, and was well looked after. Such a nice product, sound is great! BUT, with the risk of it blowing up at any moment... I just cant find it in my heart to blow another £300 on one. Creative do not recognise there is a fault with the system, even though hundreds or even thousands of people have the same problem. Their customer support really sucks!! I love creative products, but I cant see me buying any more of them. They are a giant let down. Awesome product while it lasts, **** service, **** internal components, **** support, **** company. A real shame.

The Amplifier or its power pack has failed. I would not know of a repair possibility[No user serviceable parts in side] is usually stuck some where on the units like this because they are integrated boards and service is by replacement. If it is of recent purchase get onto whomsoever you got it from.

I have a Gigaworks 750, the Audio Pod is not working, however, there is power going to the subwoofer though the power light is flickering. Hope you can help me in solving the problem. Thanks


I did fix this problem and the whole bunch of other ones with the s750 system.

"light is flickering" is a very common! It shows that there is a problem with STANDBY power supply:

1) Yellow glue became conductive (needs to be completely removed)
2) Capacitor malfunctioning C61 (68uF 450)

3) mine had TH1 cracked (replaced from PC power supply) and D9 diode.

If this successfully fixed, you will be able to get 2nd stage power supply on (Relay or power on button)

If you will have problems there, there is a whole bunch of test needs to be done (capacitors, IRF740 etc.)

Subwoofer will not play with other speakers


Hello

It looks like you have posted this before. Unfortunately, I don't know what you have tried so I may be repeating some of your earlier troubleshooting.

The subwoofer needs its own power supply to function properly. if it isn't getting enough power, the sub will not work at all.

On the back of the unit, you should see a green LED when the power is turned on. Is this light on all of the time of does it fade / flicker? This would indicate the power supply is going bad and you need to replace it.

All I need is the control pod for the Gigaworks S750


I had an extra one but I sold it. According to creative labs they do not sell any replacement parts for the speaker systems. The best suggestion that I can give is to check craigslist and ebay for the control pods.

Audio control pod seems dead


You can see about getting a new control pod from ebay or craigslist but the problem is more likely inside the subwoofer. Below I have pasted a link to a forum thread about fixing the Gigaworks S750 systems. There is not much information there about control pod problems but at least the people on the thread will help as much as they can. If you are not familiar with electronics then some of the people on the forum thread can help if you are willing to ship the subwoofer box to them.

Control pod


Double check the connections, if the connection for the control pod is good then something is wrong inside. I would say most likely thing would be a problem on the power supply inside the subwoofer box.
