Mine was the Mosfet on the right as you look atht he first picture on fixya. I know the Klipsch Promedia 2.1 systems had a 1/4W resistor, when there should have been a 1/2W. I bought a lot of 13 of those from a Best Buy warehouse that was getting rid of them.Replace 1 resistor, BAM. Still using them today. I have no idea if it's a common problem or not. When mine blew, there wasn't much solid info on what was wrong. Hence why it came down to just shorting the fuse and seeing what blew up. Ended up saving me $133. You said it would cost AU$400 for a replacement module... How much is a new sub? IMO, it's worth shorting it out and replacing what's bad. Mine's sitll going STRONG.

Replaced the mosfet and the blown resistor, and it powered right up. There's another issue, but it's working for now. WOO HOO!!!!

FYI, I finally got brave and decided to short the fuse and see what started smoking. One of the mosfets (the one closest to the edge of the power board) pretty much exploded. I'm replacing that, along with the resistor that blew. I'll report back after I get the parts to let you know if that fixed it.

My RW-10D blows the fuse every time I turn it on. I've looked over the boards, but can't find any components that are visually damaged. I'm a handy person, and have repaired 10+ Promedia 2.1 systems, but I'm just lost as to where to go from here. Spending the $100 and sending it back in just isn't in the budget right now. If anyone has a wiring diagram, or knows of frequently bad components, please let me know. Thanks, Mike
