I have the same problem as you do, although somewhat different. My subwoofer stopped working, and I popped the lid and took a look inside. (your picture) See the gray resistor on the right side? The board underneath it has been burnt and the resistor previously had colors indicating the value/tolerance. I haven't had a chance to check it with an ohmmeter, but I'm guessing it's a lot lower resistance now. You'll also notice the band on the right "snapped" from the heat at that location. Again, exact same thing happened to me and this looks like the only bad component. In my situation, I only want to get the subwoofer to work (my 4 satellites work fine, but I don't use this as my main amp any more), so I might try to shuffle the amps so that a different one powers the sub (change the jumper on the amp board and connect it to the sub). R12 = 680 ohms. R26 might also be scorched, it's probably hard to tell. http://forums.klipsch.com/forums/t/95829.aspx http://forums.klipsch.com/forums/p/84603/849925.aspx#849925 I'm going to try to replace my two resistors (I have to find R26 first), and see how that goes before I resort to using a different amp for my subwoofer than the other speakers. - Adam

Thanks for the response! This gives me the motivation to try to fix this sub right back up! [Y] This helps a lot to know. Thanks! 1a) Could this cause anything dangerous? I don't know what internal crossover can do if I connected the inputs: 2 grounds (probably fine) and 4 signals (issues?). I've seen mono-out to stereo-in before, and I haven't seen any negatives, but this BASH subwoofer can carry enough oomph to make me worry if I connected the 4 channels together to read the single bass input. Also, the receiver I'm using can optionally (if no LFE) output "LFE + MAIN", which is the "bass elements of the front speakers' channels," so it's not necessarily just dolby digital/dts LFE. 1b) I think the cleanest way would be to wire the LFE directly into the un-amplified subwoofer input inside the box itself, if I could. I have no clue if the satellites are amplified on the same path as the subwoofer, and I don't know if I can get a circuit diagram, but I'd like to avoid the satellite circuitry altogether (since I'm going to be opening it up anyways). Any idea if this is possible? 2a) Center speaker: I've looked for a PM5.1 center speaker, but none have popped up on eBay yet. I've seen some other nice Klipsch ones on Amazon and eBay, like SC-1, SC.5, and C-1, within my price range. Would these go well in my setup as a new center speaker? Adam

I've owned a ProMedia v2-400 set for several years now, with few complaints. The other day, I walked across my room and turned the subwoofer volume down, apparently carrying quite a bit of static along with me. This static discharged through the (what I thought was a dielectric) subwoofer volume knob to somewhere in the amp/subwoofer itself and it decided to disable my subwoofer for me. My 4 satellites work fine. This was actually handy as it motivated me to purchase an audio receiver (the stereo from my PS3 to my PC to my v2-400 was nothing compared to the ability to recieve DTS on my receiver and hear 4 channels) -- a JVC RX-D205S ( http://av.jvc.com/product.jsp?modelId=MODL027648&pathId=5&page=1 ) for around $160 on FRYs.com. After perusing these boards, I've noticed more than a wealth of information on fixing a broken v2-400 subwoofer, so I'll bust out the trusty soldering iron and dive into the case later on this week armed with the existing success stories here. If I find a situation that cannot be solved by existing posts, I'll certainly post my problems. My situation is pretty simple: I'm trying to upgrade to a 5.1 from my current 4.0 situation. I also want to retain the use of my JVC RX-D205. Currently the four Klipsch speakers work very well plugged into the JVC instead of the subwoofer/amp. 1) Subwoofer: Once I (hopefully) repair my v2-400 subwoofer, can I treat the v2-400 subwoofer (no satellites plugged in) as a powered subwoofer that I can connect to my subwoofer line out on the JVC Receiver? The receiver requires a powered subwoofer, so I think it isn't amplifying the subwoofer line out. A friend of mine suggested checking if I could output a powered speaker signal from the receiver as subwoofer only, but this receiver won't allow that (outputs subwoofer/LFE signal to powered subs only) I picture myself wiring the first mini jack input into a coaxial adaptor and then plugging that directly in. If I could access the 1-channel line input to the powered subwoofer inside the box directly that would be even sweeter, in concept at least. If not, perhaps I could wire both of the stereo audio inputs into the subwoofer line out (1 channel base from Receiver --> 4 channels into PM4.1 amp/sub --> 1 channel sub)...? 2) Center speaker: I'd like to purchase a separate center speaker that would work nicely in my setup, but checking the available Klipsch speakers I see a lot of selections. Which one would complement/improve my v2-400 setup best? I'm budgeting below $300, but $100-$150 would be best. I'd love any feedback on this, because it seems like I can definitely Frankenstein this awesome speaker set into 5.1-land if all goes well. - Adam
