New to the forum. Thought I'd start a thread for the new Cinema 600 Sound Bar

New to the forums, figured now would be a good opportunity to say hi! I’m a long-time fan of Klipsch products, having started with a set of fantastic-sounding Promedia 2.1’s I bought about 15 years ago. That system has had its quirks, but I’m quite happy about just how repairable they’ve been. I was in the market to improve the sound quality from my entertainment unit, but given the size of my place and the fact I have a toddler running around, having a dedicated home theatre system wasn’t an option. To address this, I picked up a Bar 48 about a year and 8 months ago as I’m familiar with the quality of Klipsch products and knew it would produce quality sound. And produce quality sound it did… until it died. With the sound bar being 8 months out of warranty, I figured I could get it repaired. Turns out that’s not the case. Per the Klipsch support centre here in Canada, these sound bars aren’t deemed repairable. No parts available, no service manual, no schematics. Nothing. Basically, if it stops working there is literally nothing that the repair centre can do to fix it, and they advise you just buy a new one. Furthermore, the service centre told me that there’s a copious amount of glue used to hold everything together, so even if you feel inspired to take it upon your self to attempt a DIY repair, nothing will be accessible and you will cause more damage trying to fix it. Instead what I was offered was a possible trade-in credit on a new unit. I was told that I could send it in at my expense, and they would offer me a Cinema 600 for $699. To put that into perspective, retail pricing for the Cinema 600 when it goes on sale is $699, so they were offering me literally nothing for the sound bar I paid $700 for less than two years prior. Basically, I was told to pound sand. Again, I can’t stress enough that I’ve been a fan of Klipsch products, but the fact that the company made a failure-prone product unrepairable and is unwilling to try and help me out struck a chord with me. I’ve seen from multiple sources that Bar 48s not powering on is an extremely common failure mode, so hopefully this thread can help some people out by adding a ray of hope to their expensive sound bar that Klipsch says can't be fixed. So for starters, the Bar 48 is totally repairable. By removing the screws around the periphery of the back panel, the main PCB, power supply, and associated wires all slide out as a unit: The Canadian service centre mentioned that everything is glued together, and that simply is not the case. Yes, there is some hot glue on the connectors to prevent the connectors from separating if the unit is moved around or bumped, but this is a common sight with consumer electronics and can be easily removed by some careful prying away with a screwdriver. Through my testing, I found that the power supply on my unit had failed. The unit is an LPS-U101D2405L dual switching power supply, made by ETOP electronics in China. The PSU takes a 120VAC source and converts it to two separate 24VDC and 5VDC rails. The 24V rail appears to power the amplifier and speakers, while the 5V rail appears to power all the other electronics, including the control panel, LEDs on the front of the sound bar, and Bluetooth functionality. I found that when unloaded, the rails output 24V and 5V as they should, but once the Bar 48 PCB is connected to the 5V rail, output from the 5V rail drops to 2.7V. This is likely not enough voltage to power the main PCB, thus causing the no-power issue that many have experienced. I have reached out directly to ETOP (as an FYI this is not an easy thing to do!), and have confirmation that the power supply has failed. Per the spec sheet they sent me, operating voltage on the 5V rail should be 5V +/- 0.5V, so the 2.7V reading is well outside of spec, which was further confirmed by their engineering department. I’ve made arrangements to have a replacement power supply sent my way (with which to compare with my failed unit), so in the meantime I was going to try and diagnose exactly which component in the power supply failed. The goal here is to provide the Klipsch community with a low-cost option to fix your dead Bar 48s. As a disclaimer, I am not an electronics savant, but I am pretty handy with electronics and am extremely determined to fix this sound bar due to this awful customer service experience. Additionally, I was going to use this as an opportunity to learn more about power supply and voltage regulator design. So as mentioned earlier, when a load is applied to the 5V rail, output drops to 2.7V. I believe this might be related to a failed component in the 5V rail voltage regulator, which appears to have a couple of components that would be relatively easy to swap out. The first is an A12N65H MOSFET attached to a heatsink on the board. The MOSFET tested fine, but doesn’t appear to provide full continuity between the drain and source pins after the gate has been activated. Again, I’m not an electronics expert, so perhaps this is normal but I ordered a replacement MOSFET to install just in case. The second component I was going to look at was the LD7552BPS pulse-width modulation controller. I believe these are used for controlling voltage, with operating frequency set by a resistor connected to Pin #4. Maybe a resistor failed? I’m not sure! Having a second, replacement power supply handy will help me validate some of these things! The simple solution here would be to have offer a power supply replacement for these units that failed, but since those aren't available it looks like a DIY approach is the only option. Either way, stay tuned with my progress on this, as I will get my Bar 48 working again, despite Klipsch telling me there’s nothing that can be done.

Thank all you guys for your genius knowledge. I am an untrained novice...a messy solderer at that! And thanks to you all, I got my amazon power supply in to my Cinema 600 and it's working (for the moment....)!!! Since they gave me an 800 (It sounds a bit better and more options for connecting the sub), I am hoping the 600 keeps working and I can give it to my friend for his new place! Did you see Klipsch has come out with a whole new line of soundbars and is sunsetting these? They are made with Onkyo. I hope they have better luck. I experienced good customer service.

Good morning, I was wondering if someone can assist me please. I purchased a cinema Klipsch 600 in November of 2021 and the sound bar died on me approximately a month ago. I came across this forum online and I was very excited to see that there was a forum dedicated for klipsch. I followed the link and I have purchased the exact same power supply 24 volts 4 amps 5 volts 1 amp and follow your instructions down to the letter the green light comes on which does suggest power going to the power supply however the sound bar still is not booting up, I was wondering if someone may have an understanding as to why this is happening. Thank you guys so much.

Hello I have a Klipsch 600 cinema soundbar. The first one had the no power issue. Klipsch replaced it and in less than a year the new 600 soundbar does a loud popping sound and then sound is reduced so you can not hear it anymore. Factory reset will fix it for about 5 minutes and it does the same thing again. Contacted Klipsch and they said it is too far out of warranty to replace it. They did send a 30% coupon for a full priced item but with the average life span of a year I do not think I want to purchase another Klipsch soundbar. My question is does anybody done or have a repair for this? Is it a supply power issue on the 24 volt side? Thanks

After my second BAR 48 died, Klipsch gave me a Cinema 600. It had just become available. Unfortunately, it only lasted a few months. I was then given a Cinema 800. Search these community forums for "Cinema 800" to learn more. Both the Cinema 800 & 1200 have reliability issues too but far fewer than the BAR 48 and the Cinema 600 do. Early firmware updates were a disaster but the latest ones are stable. You should be quite happy with your Cinema 800. I am. 🙂

As we all know, the Cinema 600 has its issues. As long as your soundbar is still under warranty Klipsch is required to provide a warranty replacement. I would open a case with Klipsch product Support. Klipsch may have some suggestions how to resolve your issue and if their recommendations don't help they should provide a/another replacement. Have you reviewed the Cinema 600 support articles?

is anyone having problems with connecting cinema 600 3.1 & klipsch connect app ?

I want to also add my voice to everyone here who has thanked Sixer for starting this thread, and to the Cinema 600 owners who joined in to include and clarify the experiences they had with our version of the soundbar. We purchased the Cinema 600 just over 3 years ago. Last month we had the exact same symptoms that have been described here, the audio getting a little static-y, followed by problems powering up and then the lights not coming on and then getting that one red light before the next time after that trying to turn it on and kaput... nothing. A quick internet search brought me to this thread, I read through it, and even though I have absolutely no electronics experience and am not a DIY'er at all, the postings in this thread gave me a clear enough vision and the confidence to tackle the task of retrieving a hardly-ever used set of gifted allen wrenches, disemboweling the sound bar and replacing that good-for-nothing ETOP power supply (although okay, it did make it through 3 years of not very heavy use). Like most here, I got the NOYITO replacement for $15 off Amazon (only 1 left in-stock the last time I saw about 5 days ago, must be a lot of us replacing Klipsch soundbar power supplies). Long story short, my replacement worked, my soundbar is back in business, I am bragging to everyone who listens about my newly acquired electronics skills, and I am grateful to all here who shared. I also did splurge and got an inexpensive multimeter/voltmeter. That came in handy to verify, before unplugging, snipping wires and removing the ETOP, that yes, had 120V AC going in, had 24V DC coming out on the larger output wires, but only had about 3V coming out on the smaller output wires. It also helped me verify the outputs on the new power supply, that as described elsewhere here as you are looking at it from that output side, 24V are the two on the left and 5V are the two on the right. It also verified for me that the NOYITO was marked correctly, with the two positive outputs being on the far left and right of the four, and the two negative outputs being the two in the middle. I can also add to the verification that for my Cinema 600 for the smaller 5V wires, white was GND, black was VDD and red was SBY, and I twisted the VDD and SBY together onto the +5V output of the new power supply. Now, yes, the NOYITO is about the same width, but shorter in length than the ETOP, and the metal heat sink grates, which are bigger and placed differently on the circuit board, don't seem to easily allow you to use one of the existing mounting holes in the soundbar backplate. I see here that some people have drilled new holes in the backplate to mount. I did not find that convenient for my 600, so I just have my replacement power supply sitting unmounted in there. The heat sinks do lay against the inside of the casing, but so far, the area has only felt tepidly warm to me. If that turns out to be an issue down the road, I would have to go back in there and figure out how and where to drill a new mounting hole or holes and get it to slide in and fit in there mounted to the backplate given that the size and orientation of the heat sinks make that harder to do. So, thanks again to Sixer and everyone here. This fix worked for my Cinema 600 soundbar. If Klipsch is smart and monitoring this, I want them to know that their reputation for quality has taken a hit with me. Being 3 years out, I did not choose to call them. But, it would have gone a long way with me if I had seen on their website a troubleshooting description of all of this, an acknowledgement of the customer experiences with these ETOP power supplies, and the offer of an inexpensive replacement that would include detailed and easy-to-follow instructions for doing so. In my book, that would have really set them apart in my eyes and gone a long way to enhance their reputation with me and win me over as a loyal long-term customer.

Hi there, I had the same issue. I understand that this problem occurs when you connect the STB and the GND. I have the Cinema 600, with the subwoofer and the satellites, and everything stayed on once the soundbar was turned off. I repaired the original (as some sheets indicated) and replaced the 400v 100uf capacitors and the 16v 220uf ones with new ones, since the regulator was OK, and reassembled with the original parts. And everything started working perfectly again.

I have the cinema 600 bought the board and did the swap. It powered right up which was great, BUT the sub now won't power down when the sound bar is turned off. ????

You might want to sit down before you read this: I contacted Klipsch and let them know that I had seen this was an on-going fairly common problem and wondered if they were covering it with an extended warranty. THEY ARE REPLACING MY CINEMA 600 WITH AN 800!!! They no longer make the 600 so they are replacing it with the 800. I'm so gobsmacked, I'm telling myself that I'll believe it when it shows up (in 5-10 business days). I'm wondering if I am delusional when I read the e-mail and receipt for it! That was a short shelf life for the 600 so my guess is they quit making them because of the power supply problem. This problem has to be costing Klipsch a lot. Not to be ungrateful but I hope the 800 has a more robust PS. At least, now I'm ready. If it has the same power supply, when it goes, I have the one I just got from Amazon! LOL! (and bonus: Now I know I need a set or Torx drivers!) Thank you Klipsch!

Hey, i hope you could help me with something here. I have received my 2nd Cinema 600 set after i thought the first one was faulty, but the new one has the same flaw and im a bit disappointed. Basically the subwoofer has strange crackling noises during low volume sections of movies and stuff, especially during dialog of men while there is no background noise. I dont really know how to describe it. Like i would constantly tap on the membrane of the subwoofer, like using a shitty microphone on a windy day. At first i thought its a faulty product, but i have received the second set today and it sounds the same. When i turn down the sub volume the cackling sound stays basically the same. Its either there, or not and after a certain volume level its gone.

Hey guys. Just upgraded to a Klipsch Cinema 600 soundbar system for our TV. Our previous speakers were a bare bones, 15 year old LG speaker system that was starting to finally burn out. No doubt the Klipsch are better quality. However, they just sound so tinny to my wife and I. It sounds like they are all treble, even though we have the subwoofer connected and working. My wife described it as it sounding like every character on the TV had a mic too close to their mouth. It actually started giving me a headache... Is this normal? Do these maybe need broken in? Or are we just not used to how good speakers sound? Thanks for the help Edit: I was also disappointed to see the Klipsch Connect app only had 6 preset EQ settings, that all sound nearly identical. I was hoping to able to custom adjust eq settings like I had seen online

Its super bowl day and I am bummed! I've had the Cinema 600 sound bar with sub woofer for a couple of years and have loved it until today. After mounting the bar from our TV display I've tried plugging it into multiple outlets and there is simply now power when trying to turn the sound bar on trying both the buttons on the bar and the remote it came from, I'm super upset this sound bar does not have many years of use and I paid a lot of money for it, I see there is a service USB port on the side where you can pair a sub woofer i've validated the power cord is correctly inserted and there is power on the outlet. Why would this happen? Is there a quick fix to this problem or am stuck buying a new sound bar?

Hello @R1c0, @itsmeray, @CH315, @Dlayhue01 I just came across this thread otherwise I would have replied sooner. I use the Surround 3's with my soundbars. First, I had a BAR 48 so I know all about those issues. I too was given a Cinema 600 as a warranty replacement so I know all about the Cinema 600 issues too. My Cinema 600 died completely after a couple of months. I had just updated the firmware to the latest version a few days before Klipsch pulled that update. While Klipsch is pretty good about providing warranty replacements, if you are within the warranty period, the Cinema 600 doesn't really qualify as a replacement for the BAR 48. The BAR has more features than does the Cinema 600 and, while a warranty replacement doesn't have to be the same model, it does have to have compatible or better features than the model it is replacing. Both the BAR series and the Cinema series soundbars have major reliability issues, especially the BAR 48 and the Cinema 600. The most recently manufactured Cinema 600's are labeled Rev 3. 😞 When I pointed out to Klipsch that the BAR 48 specs had features not present in the Cinema 600, they replaced my dead Cinema 600 with a Cinema 800 that had just been released. Through all of this, my Surround 3's never gave me any problems. Here are some suggestions how to troubleshoot Surround 3 pairing issues. Move the Surround 3's close to the soundbar, say 3 to 5 feet, just in case there are any signal strength or interference issues. Move any bluetooth or Wi-Fi devices that could cause interference away from your soundbar. Make sure the switch on the back of the Surround 3's are set correctly: One should be in the "L" position; the other in the "R" position. If only one of the Surround 3 speakers is paired, try reversing the switches on the back so that left becomes right and right becomes left and try to pair them again. If the same physical speaker again pairs successfully, that would suggest the other speaker has an issue. If however the other speaker pairs successfully it would suggest that the soundbar is only able to pair to a specific channel (either the left or the right) and the failure to pairing is due to an issue with the soundbar. If you haven't done so already, I suggest you read these Cinema 600 articles.

Here we are in April 2024 and my 2 1/2 year old Cinema 600 has dies, I presume with the same problem. I ordered the power supply. What are the names and size tamper proof screws on the back? I want to put in regualr screws because obviously these things need to be tampered with! - Thanks

The Cinema Series soundbars are being replaced with a new series. That's why you can find some great "deals". There are lots of posts about the Cinema 400 and the Cinema 600 soundbars, not all good I'm afraid. You may want to review the Klipsch support articles for the Cinema Series soundbars. If your Cinema 400 was just purchased, perhaps you can return it?

If I would had read all the above I would not have purchased my Cinema 400 this morning. I got a good deal on it and pulled the trigger. I have the sound bar hooked up through hdmi and have not had an issue yet. Been running it for the last 8 hrs. Sound is good. I regret not going for the cinema 600 or higher. The cinema 400 is not compatible with the connect app which has a equalizer to tweak your sound and I did not know that until after I setup my cinema 400.

I bought the Cinema 600 soundbar and sub combo 6 months ago for my bedroom. Everything seemed fine until recently when the subwoofer sound randomly cuts out when theres mostly dialogue, and then comes back muffled for a second. I also noticed a constant low toned static or crackling sound if I put my head down close to the sub, and muffled moments happen when scenes with bass are present. My sub is about 10 ft away with no obstructions. Power cable is plugged into grounded surge protector, but this issue still happens trying with and without the surge. Has anyone else had this type of issue? I wasted an hour on hold today trying to reach customer service, and just gave up waiting. 😔

Hello everyone. Sorry for the poor English from the translator. I recently bought a Cinema 600 SE - 5.1 - Bluetooth set. A set worth recommending. However, I have a problem that, if not resolved, may result in a return to the seller (and I wouldn't want that). I like to exaggerate the bass or treble a bit. It depends on the source, when the sound quality is poorer or I listen quietly - it is worth adjusting some tones. I downloaded the Klipsch dedicated smartphone app, but it only has predefined settings (flat, movie, music, sports, etc.). I can't find even a basic equalizer, slider for low, mid, high tones. There is something like this for other Klipsch devices, but unfortunately I haven't found it for Cinema 600. How can this problem be solved? Please help.

Hey guys, thanks for your input here. My wife's family has always had Klipsch speakers that are awesome and we finally wanted to get one for ourselves. We need a soundbar for our TV room and wanted to grab the Cinema 600. However, reading online now about a bunch of horror stories and finding out that they've already discontinued the Cinema line, I'm a bit worried. I don't like how it seems the soundbars are dying a year or two in, long after the return policy or warranty is up. Do any of you know how prevalent the power issue is on the Cinema 600 specifically? Is the 400 any better? Also, I keep reading posts here and on Reddit about a thread that shows you how to DIY fix the problem yourself, but I can't actually find this step by step instruction anywhere... Could someone guide me? Would I be stupid to buy the Cinema 600? I have to be honest, because of budget and space, our alternative is just going to be a Samsung soundbar system at a similar price, not another Klipsch product, so would really like this one to work out... Thanks guys for the input

I just found this thread because my Cinema 600 died one month short of 3 years. I have to give props to Klipsch in my case because they sent me a Cinema 800 for replacement free of charge and told me they don’t want the 600 back and I can do with it as I see fit. So…. I plan to attempt the repair on this thread and use in another room. Thanks for all the info here and I will follow up after the new power supply comes.

I have not had any issues with my Connect App but I don't use it very often. The equalizer function is pretty basic: it allows you to raise or lower levels in three ranges (lower, mid, & trebil). When I had my Cinema 600 I found the effectiveness of the equalizer to be disappointing. It's better on the Cinema 800 but not great. Since the equalization is done in the soundbar, the results depend pretty much on the soundbar.

Is there a repair procedure available for the Cinema 600 Soundbar? Mine just died and I would like to repair it.
