Re: No Power to Sub

If you think the fuse is blown replace it take card you use the right one (fuse) then see if it goes.

Lost power to my house, came back on outlet has power clock on radio works radio has no power. wall clock on same outlet works fine

There is a battery backuo in the radio. This is probably powering the clock. It looks like the radio power supply is either fried or the hardwired fuse is blown.
Take a look at the manual. If you take out the battery back up does the clock still work? GPX MP3 Player KC232S user manual

My Creature II speakers still work however the big subwoffer isnt working. I think it is probably just the cord but is there a way I can be sure

Which cord are you thinking of? If you look at the subwoofer there are 4 cords. One to the left tweeter, one to the right tweeter, one to the computer and one to the power.
  1. As both the tweeters are woring then those 2 cords are OK.
  2. As both tweeters are working then the cord to the computer is OK.
  3. As both tweeters are working then the cord to the power is OK.
  4. Therefore it is not 'just the cord.'
What I would suggest is checking that the sub has not been turned down - one of the silver posts on the sub. If that is not the case and you cannot turn the sub volume up then I suggest that you replace the system. They probably cost more to repair than to buy new.

Loud humming sound. Blown power adapter transformer. Bought new adapter same humming

The power adapter that blew damaged the amplifier circuits inside the sub (or a damaged circuit caused the power adapter to blow)... in either case, if you have electronic skills and access to a oscilloscope, you can trace the signal on the circuit board. The suspect components to look for would be around the connectors for the power supply to the circuit board.

Bose Companion 5 110v/220v short circuit

The fact that everything but the power amp is still working, it could be only a fuse protecting the output that needs replacement although this fuse is probably circuit-wise after the main fuse you have already replaced and could be soldered on the board. Worst case, the output modules are blown and require replacement and depending on the power level it may be worth repairing instead of replacing.
Most modern electronic devices can be set or adapted to line voltages from 100-240 Volts and a good percentage of the devices, using the common switched mode power supply don't need any changes made by the user since they can be inherently 'auto-ranging.'

I have a logitech x-530 5.1 system that doesn't work. when i pulled the sub woofer apart, all I found was a blown fuse. What caused the fuse to blow? Also,what would be the voltage of the secondary side?

Hi there bud , The Blown Fuse could of been cause by maybe a Power Surge or a Power Trip...If this hasnt happened then it could also be due to faulty wiring in the Subwoofer itself when it was being produced.
What you can do is , take it back to the shop and have them replace it...Dont inform them that you had opened it as then they will delete your warranty...
Hope this helped bud
Happy new year

My speakers simply will not turn on any more. i was playing music on them and then all of the sudden the power just will not turn on in the sub. Does this mean i blew them out? I didn't really have the...

Maybe. There should be a fuse. It will prolly look like a black knob on the back of the sub. Unscrew it and check the fuse. Replace it with a good fuse.
If it keeps blowing the fuse, the problem is likely in the speaker. If the problem is inside the sub, you may need to repair/ replace the circuit board inside the unit. If you can't get one you will have to replace the speaker as it will keep blowing fuses.

Cambridge megaworks 250D won't power up.

Yes, Hi there, as junk996 say, check for the FUSE , and carefully see if burn, or something is bad waired, other than this, if you can RMS the unit is better, or with warranty.
If not, check with s tech guru , for open the panel and check cables, or broken wires. (board inside the sub)
good luck!

One speaker wont work

if u have experience with the soldering of the terminals then you can open the speaker casing of the sub woofer and then solder the right speaker input wire.

dont do this if you have no previous experience and DISCONNECT THE POWER SUPPLY before doing any work inside.

My creative megaworks thx 550 does not power on anymore

ok, so far, you said you checked the power cables and switch and they seem ok. But i have run into a simliar problems with some equipment i use. Sometimes a plug may go out of a strip, but not take out the entire strip( have that problem with a power strip right now actually, in the process of fixing that)

Also, im not sure what kind of Cabinet you have, so i dont know what to really suggest other than to find either the model of your cabinet and pull up the building spec's on it, if it comes with its own cabinet or contact the manufacturer.
Without having either a picture or name and product number. I dont feel i can really help otherwise with the problem.

Please be more detailed. I would be glad to help all i can, but more details will be required
