You've got an oscilloscope and a VOM, so you must know a few things about electronics
This problem has showed up before. Just give Polk customer service a
call and they'll sort it all out for you. They're pretty awesome when
it comes to providing great support for their products. You'll probably
have to pull the amp (about 6 screws and a couple connectors - quite
easy)

If your talking about an indicator light OFF the speaker or somthing
then most likey you have somthing plugged in incorrectly. Check all
connections twice.
It is a 1.0 Ampere/250 Volt slow blow fuse that is 5mm x 20mm, often
called a "metric" size fuse. I've been in well-stocked Radio Shacks
that carry all fuse types. If you have a good electronics parts store
in your area that would be another source.
replace the IC and the capacitors using higher Voltage versions of the caps.

Hi,
It would seem that this is a powered sub-woofer which therefore would make it have at least two boards, a power supply and the amplifier board (with filters). Offhand the power supply would most likely be a simple affair consisting of a center tap transformer, bridge diode and two capacitors with a +/- voltages and probably no regulation. Based on this assumption, then there would only be 1 fuse in line with the transformer. I suspect the fuse would be at the back along with the switch or if not then it would be inside pretty near the transformer. If the fuse could be replaced and would blow again, then the amplifier section needs looking into.
This of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.
Fuse is usually located behind the unit near the power cord connection , if you cannot see the fuse then its concealed inside unit you must remove the side screw's of the unit and access the fuse ,make sure you disconnected the unit before replacing fuse or opening the unit ..if not it may result in electric shock...
Good luck....
Try first unplugging power cord for ten minutes.
Try first unplugging power cord for ten minutes. This will drain powerd from the unit and reset it.
If the unit is still dead it is probably a faulty component.
The receiver must be taken apart and tested.
Often this happens because a capacitor on the power board had blown, or an IC in the amp final is defective. The board must be tested to find out.

Check the back of the receiver and make sure all the chords coming from the speaker is connected properly.
Also make sure the power chord is connected properly.
If you cannot see any light in front of the reciver, try using a remote. If you are already using a remote try the power button in front of the receiver.
Also make sure the input mode is selected properly which means if you are expecting the sound from the DVD player or a TV set, the input mode in the receiver is selected accordingly.
If you still have some problem with the power light in that case its a problem with the power board inside the receiver and it needs to be repaired by some technician.
Thanks
