No Sound Output Despite Power And Green Light
I'm not sure why the sub isn't producing any sound despite being connected properly to both my receiver and the power source. Green light is on, output level and frequency are set to max. Would appreciate any help.

I found and article that said one of the defective parts that causes this is an open R2702 resistor. It's a 470 ohm resistor found in the subwoofer component. I opened up the subwoofer and found it back on the right hand side near the transformer. I used alligator jump wires to connect a good 470 ohm resistor across the existing resistor to test it, and IT WORKED!
Getting at the circuit board to replace the resistor is going to be a nasty project. My advice: If you don't actually have 470 ohm resistors lying around your place, you probably don't have enough electronic knowledge to repair this unit. Get a friend who is comfortable with electronics to do it for you. Their labor (a couple of beer) will be much cheaper than a repairman. The resistor costs about 2 cents (I buy in bulk - 470 is a commonly used value), so it's a shame to hand out about $100 to do the repair.
Testing the resistor is easy. To open the unit up, there are a bunch of screws on the bottom and a couple of screws on the side. Then the electronics slide out of the box. NOTE: You will have to disconnect the wires to the subwoofer speaker to slide out the electronics. Then you can reconnect the speaker to test it. BE CAREFUL! There is enough exposed high voltage to fry yourself on the board!
