Replacing R527, the two FR104 diodes, and the two caps nearby on the AC converter board fixed mine. I still have to add some cooling to it though.

Just a reminder that you can call Klipsch and get your amp 'repaired' (they sent me a brand new one) for a comparable price to other options. Once they receive your old one you will get something functional back in a timely manner and it will have a warranty on it.
As long as you find some way to keep the replacement cool it should last a while. I'm up to 2.5 years on my replacement and haven't had any trouble.
And she was about to be dumped into the trash...
I've read that Klipsch no longer offers this (I'll call them sometime). How much did it cost you and how are you keeping it cool?

you mean your ac dc board is grounded.. well you could check the Rectifiers connected to the heatsinks theres a mica insulation between the rectifier and the heatsinks.
I sent my amp to Elliott to get fixed. Same thing that everyone experiences. No response to emails, nothing - until my amp was on its way back.
breadman said:I plugged in my unit almost immediately after getting it and bam. Nothing. Not working. I emailed Elliott asking him if he would fix it again and he said he would
And how many emails did it take to get a response to that?
I actually just randomly found this thread but my 5.1's have been "broken" for a while (a few months now) with a loud buzz and very low volume. I might try contacting this Henry guy ( [email protected] ?) and take that route. Even though I could probably try doing some of the repair myself, I'm most definitely an amateur compared to whatever he does.
I am just posting here to recommend Henry aka ebayid: stpetesheperd aka [email protected] I found out about him on this board through a google search and went ahead and said fuck it and sent it to him. Anyway I just registered to post about my experience.So has everyone's experience with Henry been positive so far? I just recently got one of the Ultra sets off ebay (happened to be new-in-box, too), and already I'm starting to have some oddities. The temp of the sub is definitely a lot higher than I had expected, and for some reason, the sub's power is greatly reduced when set to 5.1 (setting the soundcard output to 4.1 or 2.1 seems to restore the bass).
I removed the daughterboard from the power supply and replaced 11 components that were discolored from heat, brittle, and/or tend to fail. These boards will reach 185 degrees Fahrenheit when working in open air (and likely higher when inside an enclosed sub without a fan), and individual components rise above 190 degrees (measured on a THX panel on my bench).
--I upgraded two 470 ohm resistors at the bottom that sometimes char the daughterboard. The replacements are 1 or 2 watt and mounted above the board for better airflow, using a different mounting point to avoid the area that chars.
I replaced
--four 1/8 watt 1% precision resistors with 1/4 watt,
--a 205,000 ohm 1/8 watt 1% precision resistor that often heats and rises in value. Yours had risen to 226,000 ohms, 11% above tolerance. I've seen panels stop working when that resistor has continued to rise. The replacement is rated for 1/4 watt and will be under the cooling airflow of a fan.
--three capacitors, and
--the 100,000 ohm resistor that is part of my cooling kit on eBay (one watt flameproof).
The board will now be under a cooling fan, so its temperature will be much lower. The resistor that rises to 190 degrees will operate at about 105 degrees.
On the power supply board I replaced 10 parts, including 6 electrolytic capacitors that can dry out over time (originals were 85 deg. Celsius; the replacements are rated to 105 degrees Celsius). I replaced and mounted for better airflow four other parts: a resistor (original is typically 1 or 2 watt; replacement is 3 watt), a fast recovery diode, a zener diode and transistor that can fail from heat.
On the main board I replaced three capacitors that are close to a couple of warm heat sinks. The capacitors can cause a hum when they fail, as had happened with your panel. The originals were rated 85 degrees Celsius, and the new ones are rated for 105 degrees.
I regreased with silicone heat sink compound the small black heatsinks of three power transistors on the main board, and reinforced their connections with silicone adhesive (these heat sinks can fall off during shipping). I also reinforced the mounting of the main power relay, which can easily be damaged during shipping or installation, and soldered 4 pin connections between two boards that can cause intermittent problems.
I installed a 92mm 11dB Silenx fan with its own power supply that will switch on when the panel is turned on. The attached page shows how the transformer can be mounted.
Your panel is running while the fan's adhesive cures. The first few hours typically expose most instances of a (rare) defective replacement part. I'll provide a 90 day warranty. If a new component is not up to specification and does not fail immediately, it will show within the first month or two, so that should cover you to a point the panel will continue to give you good service.
I wanted to take a moment to share my recent exchanges with Elliott. I have been wringing my hands over whether or not my sub (an Ultra) had failed. Numerous times over the last couple years, I would get some very loud buzzing feedback, typically after a power failure at our house (unreliable service, though I live in Indianapolis). It would often go away after days or weeks, and most recently after months. Fail means fail, so it was confusing to hear full functionality return.
During this time, I sought out Elliott, seeing his services shared here and elsewhere. Also, having heard positive things about his selection of components and quality of repair. My amp no longer appears willing to return from the dark side, spewing very loud buzzing even at zero on the control pod. I finally pulled the amp and sent Elliott my payment. While waiting for him to provide a mailing address, I looked a little further into this forum and on ebay.
I uncovered the cooling fan upgrade available from stpeteshepard (not sure if this is also "Henry"?). I decided, for what it's worth, that for the extra $20 or so, this was a good insurance policy.
Elliott replied to me several times over the weekend. First, he recommended how to pack my amp, as I was concerned about littering the boards with styrofoam. Later, he provided the mailing address and instructions on what exactly to ship. Finally, he responded with a full refund of my PayPal payment after I requested it, informing him of my decision to pursue the fan solution. He then shared a couple photos of what appears to be a homemade cooling fan solution (two smaller fans, repurposed transformer) that failed.
I respect all of his responses, not to mention his patience as I waited months after contacting him before sending payment (he requested payment in March, which I ignored, thinking troubles were over). While I haven't followed through to the end, so far I'd say he was professional and helpful.
Unless you compare all results of the fan solution and all results of Elliott's repairs and customer service of both tech's, you don't have the full story. I know Elliott is employed elsewhere, but he has had many satisfied customers, to be sure. Only a few of them find their way to this forum.
My 2 cents, for what it's worth.
Hey guys, does anyone know what can cause the amp to hiss? I thought it might have been a problem capacitor so I figured I'd just replaced all the capacitors on the AC/DC board but that apparently isn't the problem and the hiss is still there. The sats and subwoofer still works fine but I can't seem to get rid of the hiss. Any ideas?
Off the top of my head I bet your one or both of your BASH daughterboards (the white PCBs) has a bad solder joint to the module its attached to. Try heating the solder joint until it just melts and then let it reharden.My 5.1's have started hissing on and off from all the satellites whether a signal is present or not. Right now it comes and goes but It seems to be getting worse and I would like to fix it before it dies completely or never stops hissing again. They used to just hiss a little when first powered up and then the hiss would fade away with a little high pitched whining noise and be fine. Lately the hiss comes back though and gets really loud and annoying.
Are you guys really so attached to those two cheap Klipsch 8" subs and subbox that you won't buy a receiver and a stand alone sub? You can even make the Klipsch subs work but it's some effort.
I went full receiver + subwoofer (KSW-12) and changed the center to an RCX-4
