I searched and did not find anyone with this issue. After a vacation where all of my equipment was unplugged from the wall, I return to have the LEDs on top and front flicker then stop working. I suspect a power supply issue as previously mentioned in posts, but am not savvy enough to replace it. Two year old unit out of warrant that now completely cuts out at random times using HDMI. Pops a bit with optical cable (that might be the TV settings). And I seek the wisdom of @KevinBif you've heard of this one. Also, I'm super curious - with all of the issues with Bar 48, what influenced you to purchase a Cinema 800???? I love (understatement) the brand also, but it seems that the Soundbar division isn't up to usual Klipsch quality standards. [I'm a newbie so the system won't let me message you directly]

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.

I have a complete bar 48 complete with the matching surround sound speakers. Absolutely love this system, sounds fantastic. Last few months the volume LEDs were flickering, then all LEDs stopped working all together. No big deal the system still worked. Welp today the left and center speakers stopped working. The right channel still works as well as the sub and surrounds. So its obviously not a power issue. I am well out of warranty so I figured I shall tackle this repair on my own. Any suggestions or has anyone had a similar issue?

This is my second bar48. My first one died, so I bought another because I already had the matching surround speakers. After about 2weeks the surrounds started crackling. Another 2 weeks they stopped working. They powered on and paired just produced no noise. Also it seemed the center channel seemed louder then the rest regardless of setting. Today I have the day off so I decided to update it. Yay the surrounds work and it all sounds well. But now it doesnt work with my TV remote at all, it was originally automatic for both bars. It just straight up worked to control volume. Also only the front facing LEDs work and I have 2 additional ones above the volume level lit up.

The latest firmware update provides two new modes but I can find no information about them. Does anyone know what they do? Version: v83 (S/N: 106655719110001 - 106655719242000) Released: 12/13/2019 Region: Global Bar 48 BT v83 - Change Log: Improved subwoofer connection Increased Surround Output when Rear Surrounds are present. When volume is set to minimum, sub volume now mutes. Content continues playing after Bluetooth connection is made from device to soundbar. BT switches input when coming from other audio input after BT connection is made from device to soundbar. Sub Volume Increase/Decrease LED indication improved on bar Can power off soundbar when HDMI content playing with button on soundbar or remote. Installer Mode Added External Player Mode Added Various Bug Fixes

Does the Klipsch WA-2 wireless adapter work with the Klipsch Soundbar Bar 48 Subwoofer?

Has anyone had an experience fixing a power supply from the BAR 48 subwoofer? It clicks every 5 sec, output is jumping simultaneously from around 0 to around 3v. VDD is also jumping up to 14v and dropping back down. It looks like it tries to start but something is triggering protection on OB5269. I've changed OB5269 - no effect. Diodes look good, pulled out FET and checked - looks good as well. Capacitors look good. Nothing is visibly burned. I couldn't find any info on that power supply, even the output voltage.

I have a Klipsch bar 48 sound bar. Recently i am hearing clicking/popping noise from the center speaker. Anyone have any idea why this is happening?

My sound bar will not turn on. I updated the firmware back in July to this version: Bar48_2.4_V30.zip dated May 5 2020 and it was working after that. It was ok yesterday but when I went to turn it on this morning it would not come on - no lights no sound. I tried the factory reset repeatedly - power + source for at least 10 seconds. Unplugged for 1/2 an hour and tried again still nothing. After unplugging and retrying, the sub-woofer started to pop randomly. I've tried it in different outlets that I know are working and tried using the power cord from the sub-woofer. No change. Thoughts...

my ex bought me a bar 48 we split up and I will not reach out to her to ask her for a receipt now the thing had no lights I sold it to the repair shop for $25 because they said there is no repair and they wanted it for parts but now I'm regretting it thinking there might have been a way to have it repaired does anyone have advice for the next time something like that happens and how to find a good repair shop also what is everyone second go to brand I might try B&W for my theater

Update Monday 20 January 2020. I received the JBL Bar 5.1 soundbar and subwoofer yesterday. It works right out-of-the-box just like I expected a 5.1 sound system to work and sound in full-time, room-filling 5.1 sound from all sources, both stereo and 5.1 source. Let me repeat that: 5.1 surround sound full-time from all sources, whether stereo music sources or 5.1 video sources. Full-time 5.1 surround sound, loud enough to be heard ALL the time during two 2+ hour movies (Star Wars, The Last Jedi and The Force Awakens). The Klipsch Bar 48 5.1, in comparison, played surround sound barely loud enough for only a few seconds at a time and only during a few loud scenes during the same two 2+ hour movies. Also, Bluetooth paired with no problems to my computer and smartphone (Klipsch Bluetooth failed to connect on 2 of 3 units I tried). After trying three BAR 48s with 5.1 in the last six weeks, the result is obvious to me now: Klipsch fails to deliver 5.1 surround sound on the BAR 5.1, nor do they acknowledge the problems (including Bluetooth failure to pair), nor do they promise a date when it will fully work as well as the competition does right out-of-the-box. Competition 1, Klipsch 0. Game over for me. I'm happy with the JBL Bar 5.1 and will be returning the Klipsch BAR 48 5.1 today. ***** Update 15 January 2020. Where to start? Klipsch has really dropped the ball with the BAR 48, in lack of features and poor quality control. 1) Out of 3 BAR 48s I’ve had in two months, two fail to pair with Bluetooth, including the latest unit. This is a show-stopper for me. I haven’t decided whether to seek a 4th replacement or get a refund and go with a competitor which I know works well and sounds nearly as good. 2) Out of 3 sets of Surround 3 speakers I’ve had, one pair produced static, none are loud enough while playing 5.1 surround videos (such as Star Wars Last Jedi), and none play stereo sources on the S3 speakers louder than a whisper, which I fully expected to enjoy (given that simple car audio and home theater receives plays stereo sources on all speakers using ‘Balance’ for left-right and ‘Fade’ for front-back balance). I may just return them for a refund, since 5.1 is an option for me, as I’m fine with 3.1. 3) I’ve an online support request. The tech said he has forwarded a bug report to engineering. I replied I hope he forwards these concerns to marketing, engineering and manufacturing so they can decide on a competitive feature set and improving product quality. 4) Kudos to Amazon for their extended return/exchange dates during the annual holiday period starting at Thanksgiving (extending normal 30-day returns to January 31). ***** Update Mon Dec 30, 2019, 1200PM PST. In short, I received the replacement BAR 48 (from Amazon), updated the firmware (to v23 of 12/13/2019) and was disappointed (again) the Surround 3 (2nd set) speakers remain whisper quiet even with Dolby Digital and Surround lights on. To add insult to injury, Bluetooth does not connect (Bluetooth on the 1st BAR 48 worked fine to connect to both my Windows 10 computer and Android smartphone). Bottom line, if this were any other brand and I absolutely had to have 5.1 rather than 3.1, I'd shytecan it and never look back, but I'm a long-time fanatic for the Klipsch sound and Klipsch delivers for me again in amazing 3.1 sound from the affordable BAR 48. Having 5.1 with the Surround 3 speakers is an option that doesn't work for me and I'll simply return them for a refund. I can easily exchange the BAR 48 on Amazon again to get Bluetooth back online (Kudos to Amazon. Each year, from Thanksgiving onward, Amazon offers deep discounts and allows returns/exchanges through Jan 31 for almost everything). ***** Update Sun Dec 22, 2019, 1640PM PST. In short, I'm waiting to received a replacement BAR 48, then will test the Surround 3 volume output. I chatted with Amazon tech support, explained everything I have done (firmware update, exchange of Surround 3 speakers). After we tried an HDTV audio out adjustment, they will exchange the BAR 48 for a new one. I should receive the new replacement BAR 48 in a few days. Note: Klipsch tech support has not responded to my online service request in 12 days. ***** Update Dec 21, 2019, 1800PM PST. Bad news for the replacement S3 speakers I received today. I received the replacement Surround 3 speakers, plugged them in and connected them. The low-volume sound problem still exists with this new set of speakers. I have the BAR 48 Surround volume turned up all the way for both channels. I have to put my ear up to the speakers to hear them, which makes them useless. I am confident I properly installed the BAR 48 firmware v23 (dated 12/13/2019) several days ago (all the lights lit up in sequence as the PDF said they would). Update 1830PM. I updated the BAR 48 to firmware v23 again. No change in the low-volume problem. Sigh. ***** Update 12/16/2019: Klipsch just posted a firmware update for the BAR 48, firmware v23, which includes this fix: "Increased Surround Output when Rear Surrounds are present." Ironically, two days ago I returned the Surround 3 speakers and am waiting for a replacement set to be shipped to me for this exact problem. I went ahead and installed the firmware update and will be ready when the Surround 3 speakers arrive. Fellow owners, if you want to try this on your BAR 48 to see if it improves sound volume for the Surround 3 speakers, please post here and let us know your findings. ***** Original Post 12/09/2019: I have a BAR 48 sound bar, which I love. I just added the Surround 3 speaker pair and adjusted the surround volume to maximum, but I can still barely hear the sound. The surround speakers are on my desk. By comparison the BAR 48 across the room drowns out the surround speakers. My BAR 48 firmware was up-to-date out of the box (I just checked in klipsch.com, which said it has the current firmware, v14, released 7/17/2019, region Global). I've adjusted the Surround 3 speaker volume to maximum (using the Surround button on the remote as per the Klipsch PDF). Is there another way to turn up the surround speakers louder? Am I missing something else? Or should I request support from Klipsch?

I have a 2 year old Bar 48 sound bar. The other day it just stopped working, we haven't changed anything with our home setup. It's connected to the TV via optical cable. When we power on the soundbar the status lights will come on initially, then starts flickering and goes out, sound never comes on, it seems the power is still on as we can adjust the volume and when powering off then on again it keeps the same power level, but again no sound comes through The subwoofer light starts flashing blue like it's waiting for a signal from the soundbar but nothing happens. I did try to swap out the optical cable but that didn't fix it, so it seems it's not that and the bar itself has an issue. Anyone experience anything like this before? I've submitted a support ticket (#284599) about a week ago but haven't heard back yet. Also tried calling in the support number but can't seem to get through and get put on hold indefinitely before I have to give up and carry on with my day. Any suggestions would be greatly appreciated!

I have the bar 48 with Surround 3 Speakers. One of my rear speakers (I have it set to the right channel) makes a scratching noise that lasts about 1 second, but only it only happens every few hours. It happens suddenly and complete out of the blue. Has anyone else ever experienced a similar issue? I haven't tried any trouble shooting yet like swapping channels with the left speaker and seeing if the speak does the same thing on the other channel, or re-syncing the bluetooth. It'll be hard to trouble shoot so it's very unpredictable. Is it possible I have 1 defective speaker?

I recently bought a Bar 48 3.1 sound bar. I have it connected through HDMI ARC. Sounds great, just having subwoofer problems. From when I first set it up, I had to unplug the subwoofer and plug it back in to reconnect it. And every time I turn my tv on, everything comes on, but no sound out of the subwoofer. I try a reconnect (using pair buttons), and nothing. It always comes down to unplugging the subwoofer and reconnecting after that. Anybody else have this problem, and hopefully a fix for the problem? Also, I did not do a firmware update. I’ve seen so many posts about the firmware update failing, I would rather wait that out.

Update 20 January 2020. Ignore this post. Two of the three BAR 48 soundbars I received failed to pair with Bluetooth. I returned them all and am now a happy owner of a competing brand. ***** Original post. Several posts have been about Bluetooth problems on the BAR 48. Due to a different problem, I now have my 2nd BAR 48 and it seemed like BT pairing was hit and miss on both of them, but I've found a procedure that works well for me to pair to my Windows 10 laptop and Android smartphone. Basically, BT must be the source when you power off, then on, then BT will be the first source when the BAR 48 is powered up and pairing must be the first thing you do. After that, connecting to the paired device should be as normal as any BT device. Procedure: 1. Set the Bar 48 source to Bluetooth. Blue LED will blink slowly to tell you nothing is connected. 2. Power off by holding down the Power button for 5 secs. Then unplug the power cord. 3. Wait 10 secs, plug power cord in. Wait 10 secs. Press Power on for 5 secs to turn on the BAR 48. Source should (MUST) be Bluetooth (blue LED blinking slowly). 4. Have your device ready to pair (for me, Windows 10 or my Android smartphone). 5. On the BAR 48 remote, press the BT button for 3 seconds, then the blue LED should blink more quickly on the BAR 48, indicating it is ready to pair. 6. On your device, pair to "Klipsch Bar 48". Try it and let us know how it works for you.

I have a Bar 48 with a bluetooth woofer. Last night all worked normally. Today sound bar will not power up. No LEDs show. Soundbar seems dead. Woofer seem to be working but cannot connect to bar. Other devices connected to surge protector are working normally. Anybody got ideas except soundbar unit is dead? Thanks in advance!

Hi, my Klipsch Bar 48 fail to power on after the new firmware update. Totally no power even after changing power cable and wall socket. I am trying to update it with the new firmware following to the instruction provided, there were no response when I plug in the USB, hold the power button while connection the power cable. Afterwhich, the sounder fails to power up. Does anyone having the same issue?

I just recently got the Bar 48. I have the HDMI (Arc) from my TV going into the soundbar. Numerous times the audio would just go out, and I'd have to fiddle around with the inputs on the remote to get the sound back. I'm not sure why this is happening. When I switched to the optical cable, everything seems fine, but then I lose the benefits of the HDMI Arc. Has anyone encountered this issue?

I’ve got cracking in my wireless Surround 3 speakers connected to my Bar 48. It’s intermittently R or L or both at once & seems to come when I’m switching a channel or source. Switching surround mode off eliminates it until I turn surround mode back on, however unplugging the surround speaker seems to reset it resulting in no crackling. At first I thought it was cable related, but occurs with both comcast and ATV, then I thought it was related to using the dialogue mode, but that wasn’t it either. Looks like other folks have the same problem on the forum but I don’t see any answers there. I’m wondering if the issue is WiFi related and unplugging the surround speaker resets it’s little WiFi chip or settings? I don’t have to re-pair the unit to the Bar 48 after repowering the unit which makes me thing it’s not resetting to a default mode…any suggestions on preventing this intermittent crackling?

I’m a bit of a home audio noob, but I currently have a 5.1 setup in my home. Moving in January to a new house without existing wiring for 5.1, so considering the Bar 48, but curious if I can utilize this setup with my current Yamaha receiver, or if I can/need to forgo the receiver and just hook up the bar directly to the TV. Thanks!

Hoping to get some feedback / recommendations for the best Klipsch soundbar to go with between the Cinema 600 vs the Bar 48? Anyone tried these that can give some thoughts and impressions between the two? They both cost $499 each. I'm not really sold on "wireless" vs hardwired. And front firing would be better for the sub. But, unfortunately, the soundbars all come with down firing subs. Plus, I live in an upstairs apartment with a woman in her 60's below me. Her living room is right below mine. So, I'm not sure if a soundbar is gonna be the best option for my living situation or maybe another set-up such as either satellites or bookshelf speakers with a front firing sub. What do you guys think?

Hey everyone. First time posting here. I have a Bar 48 Soundbar and a Toshiba Fire TV and I'm having a problem connecting the audio with the provided HDMI cable. It's not working. The sound is great and works fine with the optical cable but nothing with the HDMI. Am I missing something? I've searched all over for answers on this. Is there some trick I'm missing? Any help would be great. Thanks.

I have ordered the sound bar twice, both times it has came broke in half in the same spot. For whatever reason in the packaging instead of using styrofoam in the middle of the box to support the sound bar there is nothing. Just free space... So I'm wondering if they have changed this with the cinema 600? I really want to have this on my tvs in my new house. But not if they are gonna all be broken. So does anyone know if the new 600s are packed in styrofoam front to back?

Not sure what the heck is going on! 😞 ... Device was actually fine but Surround speakers were failing to be paired. Followed Klipsch instructions and went ahead to install Firmware Update. I followed firmware update instructions as is but it never gets installed successfully. All LEDs do not glow at all during the update process, instead, just the HDMI LED glows Orange with Speaker Volume LEDs at level three which should actually happen after ALL LEDs glow. After power OFF and turn ON again, remote functionality will work only for UP or DOWN buttons or SURROUND button (holding down for a few seconds). UP or DOWN buttons actually turn ON LEDs one after the other in line. Weird! Am I missing anything in FW update process? Any help will be greatly appreciated!

Hi all, Has anyone encountered any problem connecting their Bar 48 with a Sony Bravia XBR tv VIA hdmi? HDMI port 3 for Sony is the ARC port but get no play back. Have tried changing the inputs to the bar with no luck. Playback VIA Bluetooth works so speaker is operational. Any help would be greatly appreciated. Take care, Jag
