Logitech Subwoofer X540 PC speaker System

maybe something in the speaker(s) are broken.

Nominal Output Power (Total) -- 2.3 Watt


On the back of the right speaker where the power cable is connected there is a sticker where you can see the voltage the speakers are using. You should read there 120 V - 60 Hz 100mA.

You will have to use a voltage adapter from 120v to 220v. (found in electronic shops) that maintains the Voltage stability.

Best place for manuals would be Http://www.retrevo.com - try there! :) Elle

Recheck your wiring and instructions. If your woofer is self powered perhaps the amp is no good. Actually it better have amps since the laptop output will not power those speakers.

Hi
Did you find any help, I have the same problem here and I need a new transforme, please did you find anything
I have x-540 too.

You would need to rewind the coils.Do not try to do it by yourself if you have no idea what you are up-to...this time it was transformer next time it could it could be your circuit.Take it to a professional,the charges won't be much.
Good Luck.

Check the main power transformer.

ohm out the primary side should be about 2 ohms. and check for 120v ac when you power it on.

If 120v is present on the primary side check for ac on the secondary. if none you need to replace the tranformer.

If it doesn't have 120v ac on the primary there is an open fuse or bad solder connection.

If you find an open fuse check for a shorted output transistor pair.

good luck

Goodday remmember that you have to have a 5.1 sound card to be able to use a 5.1 sorround sound system.the 5.1 has more plug inputs to plug all the speaker FRONT REAR and SUB.

i believe you have something connected wrg since your pc only requires one jack from sound card. to you subwoofer then its seperated to he others. read the book on *********** board to see if you can change your options on the sound configuration.

Actually i haven't fixed the problem as yet but i did find some info that would help me to fix problem.
I went to google and entered keyword,,, Electronic parts,,there came up a page,,and i went to several manuf sites till i found a replacement transformer,,then i disassembled the power supply and am now waiting for a replacement transformer.
