Regarding Sony SA-WM250 Subwoofer

Well i had this subwoofer for some time now, but never abused it, and it performs great, except the odd time when the bass will cut out..... then kick back in. Any ideas to what this may ? I checked my cords and connections, messed around with them a bit, and nothing happens to the bass, so thinking it must be something else, i am using a sony amplifier model STR-de597 hooked to the playstation 3, but im sure all my settings are correct. Any help would be great!!

Re: Regarding Sony SA-WM250 Subwoofer

There is probably a bad solder joint or loose wire inside of the sub box. If you can, unplug the sub, take the screws out and remove the back to inspect the circuit board. A clean solder joint is pointed and shiny, with the solder evenly distributed in the hole. Also check to see if any plugs are loose. Plug in the audio input and then the power, but be very carefull not to touch anything inside the box while the cord is plugged in!! Play some bass at moderate volume so there is pretty constant sound. Now, take a screwdriver with an insulated handle and gently tap around on the connectors and circuit board. Tap a little harder if nothing happens, also tap in different areas to try to force the sound to cut out. You can try to locate where the bad connection may be by tapping lightly and zeroing in on the location. When and if you find the problem, you will need to solder the connection with a soldering iron. If you don't have a friend to help, try a local electronics store. Good luck!

There is no power to the subwoofer when its pluged in

hi; try to check the power cord and AC plug if still good condition, if ok.
open the back cover of you wooper using screw driver,search the fuse where AC cord was connected,
if you find the fuse check if it's blown. some wooper has varistor and thermistor for protection,
try to check if it has burn parts, you cen remove it and replace it by soldering iron, you can buy these parts at your local electronic store.
if you cannot do this soldering things, call a repair technician
thanks hope this help you,,,

I have an older model sa w305 subwoofer, Its in good condition. Just need the fuse that has blown. can you please tell me what to get and who carries them fuses?

Hi, first take out the old fuse. Make a note of ALL the information on it. Then vist either Radioshack, Maplin (UK) or Ebay.
Make sure you ask in store or the supplyer on ebay to make sure it is a "LIKE for Like" exchange ...all except that the new one should not be blown of course :-)
