Would greatly appreciate some help. About 2 months ago my DSW PRO 600 started making a noise and then would produce a large thump noise with out the AVR being on. It would do this several times at random intervals. I discounted it from the AVR and unplugged it. Went back several days latter and plugged every thing in and turned it on. It didn't make any noises so I tried watching a movie. At first it seemed fine but then it started making random noises again. And finally another thump. Stopped the movie unplugged everything waited for several minutes and plugged everything in turned it on and the green light would come on for a while and would then go red. Did this several times and then the light just stayed red.
I purchased the sub from Polks ebay store as a refirb. I did contact the Polks CS and as expected it was out of warranty. Options were to buy a new amp for it or get maybe look at a DSW 505. Really would like to keep this sub but not really wanting to spend the $ right now for the new amp. So having nothing to lose I finally got around to popping open the hood and taking look see hoping something would jump out at me. Below are a few of the pictures. Anything not look right? Can't really tell if any of the caps are bad. Input greatly appreciated.
