Humming is always caused by low earth resistance so check the earthing.

SOURCE: JBL PSW-D112 Speaker fuse blow immediately after replaced

The Problem in this unit is the Amplifier module S64AMI,which is surrended in a black heatsink, filled with epoxy, not serviceable, the bad news is that JBL discontinued this module and is really hard to find, sorry....

What is the size of the JBL PSW-D110 fuse?


The fuse is a 250volt 1.25 amp slow blo.
First thing I would do is check C6 to see if it is bulge or blown - regardless replace it with a 10ufd 100volt Non-polarity capacitor. If the fuse blows again unplug the blue wires from the transformer and plug in unit to an outlet. If fuse does not blow then problem is on PC board. I have a service manual for this item. Probable causes on PC board are Filter Caps, Bridge rectifier (DBA), Amplifier module, or fragments of C6 even causing shorts on board if it had blown.

I have bought C6 from MCM Electronics for under .50 cents but you have to put shrink tube on one lead and bend it back along the body and solder both leads in the board.

Good luck

Ws having to leave volume at high level for sound now smoke and blowing fuses


All you need to do is replace the part that is smoking and the fuses and the unit might come back to life. As the burning part is most likly the cause of the fuse blowing.

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.

JBL PSW-D112 Speaker fuse blow immediately after replaced


The fuse is designed to protect the circuit and prevent fire. When a fuse blows it is because it is getting to much current through it.
In some cases it could be because you replaced the fuse with one that did not meet the specs of the required fuse, there are different types of fuses and you should always replace with exactly the same type of fuse.

Do not replace with a higher Amp fuse, you could end up frying the amp at least. It's not a safe thing to do since there is an off chance of fire from using the wrong fuse.

If you have the right type of fuse installed and it is still blowing, then refer the unit to a qualified service center for repair, or look for a new replacement Amp.

My JBL PSW-D110 started humming loud... The fuse is fine and the power LED displays is illuminated in green. However the sound is unbearable... It would like to replace the entire IC panel if its most cost...


Hi calsunbelt

there are some caps that fail in the power supply. If you are up to doing some electronic repairs, I could talk you through it and tell you what parts to check.

JBL PSW-D110 Humming Loud


If I remember these correctly, there is a bad coupling cap in the amp section. You should see it as the top should have ballooned up. Replace the cap and you should be OK.
