Spherex surround sound wont stay on

My Spherex XBOX surround sound system won't stay on. If I flip the on switch and then turn on the power with the remote control it stays on for about ten seconds and then turns itself off. I can't figure it out and the company is no help. Any ideas?

    I have the same problem but I doubt it is heat as the sub unit that houses all the electics is sealed hand does not have any ventilation...

    I bought my Xbox Surround Dound System last Feb. 2007, st Futureshop, and I'm having the same shutdown problems as the others. It worked fine for about 2 months and then WHAM! - it starts shutting down after about 10 secs. I'm not mechanical/technical so I'm stumped as well. But, I will check for the soldering issue to see what I can see and let you know.

Mr. Vargas is right mine also won't turn on and upon further inspection I found burn discoloration on the boad where the two power cables are connected. The burn spot is where the four diodes are locaed and the big power cable connection. I am not sure how to replace these diodes or where to find them. Never done this stuff but will try for sure. Please post if you have any suggestions. thanks

Oh yeah, I got the Diodes from RadioShack

I had to go to a bigger diode to fix my problem, I went with part number 276-1144 (3amps/400PIV).

Good Day Everyone.
I acquired said speakers off a family member with the same problems. Spherex went out of business but the main head company exists in Canada. I spoke to a representative from the head office, the spherex xbox system suffers from cold solder issues and catches fire because of it. When I pulled of the assembly off the sub woofer box, I noticed that on the board the sub woofer speaker and power transformer are connected to, it had burn marks on where a bank of 4 diodes and power resister are connected. That area needs to be resoldered to adjoining solder spots. this will stop problems with power and sound issues. P.S Make sure diodes didn't burn out. Audio Products International (API) still has parts for sale.

That is easy, something is causing it to overheat and the system has a self shutdown. If you can keep the unit on without it shutting down than it is not a heat issue. First check for heat issue. Make sure it is getting enough air flow or that it is not clogged. Find your warranty, you likely have a power problem if it is not heat.

Speakers have hiss and crackle but no sound coming through optical feed on spherex xbox 5.1 surround system

the speakers plug/outlet is usually at the back of the computer you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good
try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the sound card and the CPU central processing unit dust causes static to build up in a computer
hope this helps

Spherex XBOX surround system has started shutting itself down after around 30 seconds. Prior to this, the display starts "pulsing". Is this an inexpensive repair, or should I ditch the system and buy...

Hi there bud ....What i suggest is , if you still have a warranty , send it in and see what they can do....Otherwise Compare the price of a repair and a price of a new one...and there you go :)

Spherex Xbox 5.1 Surround suound..USB does not work

If the xbox is not able to recognise the usb, it is most likely that the product is not compatible with the xbox i would look for an adapter which would take the usb connection to the xbox's analog connection, or if your speakers have a stero 2.5 connection then you can easily find an adapter to connect to the xbox's analog connection in the back, the analog connection is the red and white ports at the back!.

Freezes, no sound, won't turn on!

Hi Joeker, I believe you have a problem with heat. Also to get this problem solved, you need to open the main box and clean it up real good. I use a paint brush to dust off the circuit boards. Clean all the dust and lint out of the box. Put it allback together and make sure the main box has plenty of ventilation. do not set it on carpet, this will restrict it's natural circulation of air. I truly hope this helps you.
