Repaired a PSW505 yesterday

Picked up via Craigslist for $30. Power light turned on but no sound. Previous owner tried replacing the speaker with no luck
Polk wouldn't supply the schematic (thanks guys) but it turns out that the Klipsch RW-12 "Linear board" is somewhat similar, so I referenced that (Google for manual). The Power supply was putting out the proper voltages so I then moved to the Linear board. Though it took me a few hours to figure it out (no stinkin' electronics classes for me), it was the very first capacitor in the signal chain on that board. (C100/4.7mf/35v) The cap was open, who knows why.
Anyway, I thought I'd throw this out there just in case someone else has the same problem.
