Sony SA-WMSP87 Active Sub -- No sound, but can still turn on/off

Hi,

I have an active (powered) subwoofer that came with my Sonyhome theater in a box system. I am not sure what the home theatersystem kit model number is any more, but the model number of thesubwoofer is SA-WMSP87. Just this past weekend, the subwoofer stoppedproducing any more sound. When plugged into the electric outlet, I canstill turn on the subwoofer when the power button is pressed. Just nosound comes out. I swapped the RCA from the A/V receiver to thesubwoofer, and still no sound. I also borrowed a similar Sony poweredsubwoofer from a friend and connected this to my A/V receiver to makesure it's not the A/V receiver or the wire.

What could be wrong? Please, any help would be greatly appreciated.

Of the Phillips is not a home theatre system them you can but you will have no volume co trol of the sub. If it is the alot of philips home theater in a box (htib) use special plugs...you would need to change the cable end of the sub to a compatible plug.

Sa-he70 subwoofer no sound


Hi, The sub woofer does have a level control, is this indicating that the level is moving?
Woofers are a power device and usually active, i.e. needing a power amplifier to feed them. If this is a stand alone speaker though try using an AA battery on the wires. you should here a click when you touch a battery on it. If you can see the cone move out then the wire that goes to the + of the battery is the red or positive wire, if not turn the battery around. do not use anything higher that AA i.e.1.5V If you hear a click the speaker is ok and the amplifier is either faulty or not turned up.

The required fuse is 1.6 A / 125V an is blown, I wen to radio shack and bought a 1.6A/250V and it has blown 2 already, what can I do or check to fix it? This is a Sony Sub-woofer model sa-wmsp1.


Hi,
If power transformer T1 got shorted or its output voltage got shorted for some reason, fuse will blow in Sony SA-WMSP1 active subwoofer.
Check power transformer, D401 bridge rectifiers and IC301 power amplifier out chip. Any of them is bad.
Let me know if you have additional question.
Thanks.

Can i hook up my SA-WM20 subwoofer to my sony DAV-S500 home theater


As long as your sony reciever has a sub out connection you should be able too. This powered sub you have has a rca sub input which should coincide with the receivers rca sub out.

Subwoofer noise


You didn't say is your sub active or passive.If its active first check signal cables from theater system,power line of the sub, it has to be the same phase as the system.If its passive take a voltmeter disconnect the sub from the system and measure for DC voltage on the SUB output on the system when its OFF.If DC voltage is present your amp is damaged.It can also be that the preamp circuit for the sub doesn't mute the input when unit is on stand by and you hear frequency of your power supply (50-60Hz) on the sub

Sony Active Subwoofer noise


The circuit that should be turning the sub on and off based upon the presence of an audio signal is not working correctly and the sub is trying to reproduce 60 cycle hum. The unit needs service.

Subwoofer: Active or non active?


Hello Smegboy,

Yes, you are right. This receiver is rated at 100WRMS output in all 5 channels (2-front, 1-center and 2-surround) while in Dolby Pro Logic operation. The subwoofer output is line level only (not amplified), which means you need a powered subwoofer to be connected to this output. A non-powered subwoofer could be used but, you need an additional amplifier connected to the subwwofer output from the receiver to drive it.
Let me know if this helps.
