    Just a courtesy heads up: I am still repairing Klipsch's ProMedia 5.1. This thread has not been very active recently, so I get emails asking if I am available.
    As others have noted in past years on this thread, my contact email with juno is correct. Not sure if I may post my own email address. (This is my first post on hardforum).
    I have used thousands of Nichicon and Panasonic low impedance/ESR electrolytic capacitors for the power supplies with excellent results, but now after a dozen years repairing ProMedia 5.1s, I am exploring the option of using audio grade capacitors from pF through uF sizes.

    Funny thing is. I have a ProMedia set that I've sort of pieced together. And I believe the subwoofer is not outputting to the speakers. The sub works fine for bass though. I might get some cracks from the speakers, but overall... nothing. Would love to get this fixed.

    There are a few typical causes for the satellite speakers to not work--from as simple as a failing 2N5551 transistor or 22v zener diode, to replacing a ceramic BASH HC1011 module (sometimes it will make noise or be intermittent). I am still brand new to this forum, so I am not yet familiar with how to go about helping you further. You can find my juno email listed by others previously. Not sure if it would look like seeking business to provide it here.

    nope he's not, i still have a juno as well, i for the life of me cannot find out how to delete that account so i left it alone

    anyways, i found henry on this very thread by googling klipsch 5.1 ultra repair and contacted him (did not remember i contacted him a few years ago and forgot i did to ask)
    shipped my amp to him, the repairs were extensive and i should have it back next tuesday.
    he did notate the "repairs" that elliot-tronics did hahahahah

    communication was A+, emails were clear and listed everything he repaired/swapped out.

    can't wait to get it back, been probably 5 years + since they last worked. i had them repaired twice and everytime they died again within 6mos-1year.
    once by klipsch when they repaired (before sybesma or whatever), and once by elliot. i gave up at that point and shelved them until now.

    i'll report back once i'm using them again, and 6+ mos later after extensive use if i can remember to.

    Henry has mine right now and he's been pretty good with communication. I'm curious where my repair stands.

    received it back today, fired it up and it's good to have the system working again after years
    don't hesitate to work with Henry everyone.

    Hey guys, first post here. I just ran into a problem with my Promedia 5.1 Ultra's yesterday. I bought these brand new probably in 2003 and have NEVER considered looking into any other speakers for my pc, so if I can get them fixed I'd be very happy. What happened was I was doing some cable management in my office where my pc is, and while playing music through my speakers from my pc, I disconnected the right rear channel, not really thinking, or thinking anything could happen. Well, that did something. Sound is incredibly low and distorted. My left front speaker barely makes any audio. The speaker is good as I tested it on my home theater setup, no issues there.

    I took apart the sub, the fuse looked intact and good. Wasn't broken or burned or anything. I didn't see any burned areas anywhere on the boards (though I didn't look TOO crazy close at everything), nor did I smell anything. All the speaker wires are properly connected, as is the connection to my computer. I tried connecting my phone to the control box, same audio issue. Headphones work fine though from the control box.

    Here's a link to a video I took last night, I couldn't really turn the sound up as my 2 kids were sleeping. But even at this level, sound should have been clear and loud.


    Just for reference, I typically leave the speakers at level 55 and use the windows volume to adjust. When music was playing it was pretty low in windows, but the speakers were set to 55 which is pretty loud for them. Any help is greatly appreciated. I feel it's something with the amp or power supply, which seeing these are a quality speaker system can be fixed. I just put in a help ticket with Klipsch.

    This post is long overdue. I had my Promedia 5.1 Ultra amp repaired by Henry in May of 2015 after finding his info here and reading all the success stories. I had the full work-up done... new BASH modules, the cooling fan and an assortment of other upgrades and preventatives. Henry's work and communication are top rate... let there be no doubt for anyone in need of his services to have him do the job. It took me a little over two years to get things sorted out enough at home and reset my office and set up my Promedias again (yikes, time flies, doesn't it), so I was well out of Henry's warranty period. Not too worry, they sprang right back to life and sound as good or better than they ever have. When my amp gave out, I was very disheartened that nothing else on the market really filled the gap left by the PM Ultras... I am very happy that Henry was able to breathe some new life into my system.

    In short... props to Henry for a fine job at a fair price. If I ever need to do this again, there will be zero hesitation to get in touch with Henry again.

    I'm a long time lurker, but created an account so I could add to this thread to say that Henry is still going strong. I sent him the amp from my Promedia Ultra 5.1. He fixed all the problems, fixed a few other things that were likely to go bad soon, installed the cooling fan, and got it back to me very quickly at a great and fair price.

    I've only had it running a few days now, but it sounds amazing. I've had these speakers out of commission for a few years, and had forgotten how amazing they sound. Super glad I got Henry to fix these instead of buying something new.

    If you have a bridged amp circuit, touching the two speaker leads together instantly burns your amplifier. I learned that the hard way when installing car amplifiers as a teenager.
    So your amp is burned. If it's a cheap one (which I gather it is) just replace it with something better. And be careful not to cross the beams! Haven't you seen Ghostbusters???

    Edit: Uh, necropost

    My 5.1 amp finally just died. With HDMI surround I wonder if promedia is a thing of the past.

    Henry sells a fully upgraded amp+ control pod for 299$ and is still going strong on ebay as stpeteshepherd.

    Is it worth it to fix this system or invest in a new powered sub and 5.1/7.1 receiver with less wires around my house?

    My PM 5.1 center channel doesn’t work—there’s an electronic hum coming from the speaker. The volume control module works because when I turn it up the noise/hum gets louder from the center speaker. The center speaker itself also works fine as I tested it on another (working) channel with music playing. I basically use my PM 5.1 as a 4.1 system for which it works fine. When testing the center channel I use MusicBee upmixed to 5.1. It always worked this way until the center channel eventually gave out.

    I too was scammed by Elliot-tronics. He replaced several resistors with higher temp ones, and IIRC, a transformer. It worked ok for about 2 months after the repair but then the center channel stopped working. By that time I could no longer locate him on ebay or elsewhere. I subsequently installed a cooling solution specifically made for the PM 5.1 I bought from ebay. As aforementioned, I now use it as a 4.1 system, but games that output to 5.1 (Res Evil Rev 2 for example) lose the audio entirely so I have to set my x-fi to 2.1 mode. Really sucks because I lose a lot of atmosphere in the games as I have the speakers set up nicely in my home office.

    Only recently have I sought to repair the unit again. I think this time I’d like to do my own but would like some guidance as to what to look for.

    So basically my Qs are:

    1. Do any of you know which part(s) I should replace to repair the defective center channel?
    2. How does the Logitech Z906 system compare to the PM 5.1?

    I really like the sound of the PM 5.1. Years ago I tried the Z5500s and thought they were too bass muddied, with no way to set it to get the great tight bass of the PM 5.1.

    I would suggest to stop trying to CPR the old equipment and get something else instead. It's a losing battle and the system wasn't exactly high end even when new.

    Don’t go for the Logitech’s, terrible sound quality. They eq’d The system much like dre beats are for bass, where they just lower treble (which they weren’t good at anyways) and boost low end frequency. The sub was also terrible, by terrible I mean the worst part.

    Hey guys, new to the forums here..
    What exactly does the Bash HC1011 chip do?

    The reason im asking is because i have the PM 5.1 THX, and i too had problems with the lower chip. (the one that's on the bottom of the board)
    I kept messing around with it by moving it a little as previously recommended earlier in this thread, until a few days ago when it "broke" off (too much back and fourth bending).
    Funny thing is- they work fine now! all channels and the sub! no more screaching noises or anything.

    one thing i HAVE noticed is that the amplifier runs EXTREMELY hot now... feels like you could cook an egg on it hot..

    Strange. I have a set of Logitech Z560's for over 15 years and I bought them used. The original control pod's volume had a static when I would play with the volume. A used replacement pod from fleabay solved that issue. Stilll cranking out till this day.

    So they continue to produce crappy sound for years. You consider that good? I consider it an unusual punishment.

    Not really. I enjoy it and sounds just as good now as they did 15 years ago. Hey back then the klippes were quite expensive, so I got these. Beer money and my tunes. Yeah they're not klippies, but I do enjoy them. Sry if that offends you.

    That doesn't offend me, you're free to use any equipment you like. You can consider yourself lucky if you don't have to spend a fortune on audio. For enthusiasts however, that route doesn't exist.
