Question about Sony SA-WM500 Subwoofer
Right before the subwoofer stopped working it made a rattling sound that resembled more of a problem regarding the amplifier rather than the actual speaker (I cant explain the sound too well). Ever since it has stopped working, nothing appears to be wrong with the speaker cosmetically (the cone is not damaged or stiff). When I press the button, the green LED still lights up. However, I do not hear the actual speaker "turning on" or "engaging" like it used to about three to five seconds after pressing the button. Nothing happens when I run sound through it. Any suggestions?
I had a problem with no audio and I recently found the fix. When thesub still worked and you turn it on you hear one relay click and thenabout 5 seconds later a second relay clicks and the audio comes on. Theproblem I had lies with that second relay. When you take the case apartthere are 4 circuit boards. The big board with the two big bluecapacitors is the main board. Well next to the two blue capacitors is ablue relay. That relay had a pin that came un-soldered from the circuitboard. I re-soldered that pin and the sub works just like new. If yougo here http://www.eserviceinfo.com/downloadsm/20627/sony_sawm500.htmlyou can find a free service manual that has the wiring schematics forthe amp. Hope this helps!
