Hi Andy, Thanks for the detailed debugging tips. Based on your tips I have now revived my iFi to full working condition. Here is the summary: I procastinated for a couple weeks after getting your tips, just because my two satellites were working and it was only the sub-woofer that was not working and your tips looked liked I neded to spend a lot of time. (I had replaced the fuse with a new 2.5A last month as described in my original mail and I got the satellites to work but had to disconnect the subwoofer to keep the fuse from blowing again). But this week the entire system went out cold again, likely because the 2.5A fuse blew out again. So I read thru your tips again and got a pack of 3.15A fuses from RadioShack. I did only the check1 visual inspection without disconnecting any wires and found everything to be in order. The yellow coated disc was not cracked nor damaged. I then went directly to replacing the 2.5A fuse with the 3.15A fuse (lazy I guess to actually disconnect each of the wires and test like you have mentioned. If this one blows then I will do all of that). Then I connected my sub-woofer and speakers and everything works fine now. Just have to wait and see for a longer time if this continues to work. Thanks again for the help: I spent $6 on the two packs of fuses but your advice helped my regain my $200 iFi system to its full working condition without taking it to a repairman. harish

Hi Andy, Thanks for the response. Yes I am using slow-blow fuses only. I double checked to make sure that that is what I got from Radio Shack: http://www.radioshack.com/product/index.jsp?productId=2102760 harish

After reading thru the forums and trying out some things, I am posting in the hope that I can get some help from the community. My iFi speakers (purchased at Costco) are about 2 years old and likely out of warranty. Last week, they just did not power on. After reading this forum a bit, I opened up the sub-woofer and found the fuse was blown. Got the replacement fuse from RadioShack and put it in. I tested before connecting anything with just the circuit board and ipod dock plugged in and it seemed fine (no speakers and woofer connections made). Next I put back everything and made the speaker and woofer connections and then turned on and the fuse blew even as I turned it on. So I blew couple more fuses before narrowing down the problem to the sub-woofer. If I made the sub-woofer connction to the circuit board, the fuse would blow out. The RSX speakers themselves are fine. Now I have everything back and working except for the sub-woofer. Just looking for some help on repairs. I read about replacing capacitors. It seems a bit out of my expertise level though I could read up and do something with a soldering iron if I was sure that it is the capacitors. But I cannot be sure it is the capacitors or the sub-woofer itself. Any way of narrowing this down to decide if it is the capacitors or the sub-woofer? Also, how to remove the grill from the iFi sub-woofer and detach the sub-woofer from the frame? Can it be replaced with any 8" 8 ohm or 4 ohm sub-woofer (it says 6 ohm, but I dont see any 6 ohm replacements on the market)? I just dont want to trash such a fine system on account of the sub-woofer not working, but without the sub, the system does not sound as good. Any help from the experts is greatly appreciated.
