The brown resin is glue that changed color due to heat and age. Rarely have I seen it cause problems. So unless you are having problems, No.

New sony receiver str-dh740 has 2 RCA plugs for sub woofer. How do I connect to psw350


only use one of the outputs from the rear of the str-dh740. and use a rca "y" adapter where you plug it into the subwoofer so that both of the inputs on the sub are getting a signal.

Polk Audio DSW Pro 500 remote doesn't"t work. I've tried replacing the battery and was told by another technician to take the sub-woofer out and make sure the cable is plugged up to the amp and the IR...


Is this NEW? Or did it just fail spontaneously after working for awhile?

Is this just a remote control issue or is the sub dead, too?

From the manual...

No sound coming from subwoofer.

If hookup is "SUB OUT" to LFE, check and make sure your receiver is set to Subwoofer=YES. If hookup is via speaker wire, check that the polarity of the wires is correct.

Subwoofer has no power.

Is the AC MAIN switch on? Check outlet; check fuse after unplugging the subwoofer. The fuse is located under the power cord
receptacle. Fuse type and rating is found on the back panel.

Remote control doesn't work.

Remove the plastic tab to activate the remote control's battery or try replacing the battery. Ensure the IR sensor is not blocked.

If it's a new problem with a previously working remote...

Polk Audio PSW202 subwoofer. Replaced burnt fuse but blows the next fuse after connecting to amplifier and powering on. What else can I do?


Fuse probably went bad because either the large filer capacitors at the edge of the PCB went bad and or the final output IC mounted on the heatsink(15 pin) fried. Check the capacitors and all the semiconductor components on the board for burn marks or corrosion. You have to remove the heat sink clamp from in front of the output IC to adequately visualize its condition. In fact you might have to remove the large aluminum heatsink attached to the chassis to get a good view of the IC. If it or the heat sink clamp show signs of thermal burns you need to replace it. The IC is a TS TDA7294 mono audio amp available at Mouser Electronics. Replace the 35V 4700mF caps with 50V 4700mF caps. You will only have enough space on the top of the PCB for one of the larger caps. I mounted the other on the circuit side of the board. Note the polarity of the original caps and respect it in their replacements. The fuse is a 5 X 20 medium speed slow blow 250V 2.0A glass fuse.
