So you connected the GND to the 5V - and the VDD & STB to the 5V + but what do you plug to the 24V output? Quote Link to comment Share on other sites More sharing options...

cmoore7 Posted October 30, 2022 Share Posted October 30, 2022 I want to thank all that have contributed to this thread. Shame on Klipsch for telling us all that they can’t be repaired. Took me about a half hour and $14 and I was back up and listening to my Cinema 600. Quote Link to comment Share on other sites More sharing options...
cmoore7 Posted October 31, 2022 Share Posted October 31, 2022 I did want add something to my first post. while the fix did work, I was on the phone the same day after the fix and started to get a tremendous buzzing noise coming from one of my surround speakers. I had to unplug. Any thoughts as to why this might be happening? Quote Link to comment Share on other sites More sharing options...

Andy7778 Posted November 6, 2022 Share Posted November 6, 2022 With a little confusion I figured out how the white wires needed to be hooked up. It works amazing! Thank you so much SixerFixer. I will not included the nasty email to Klipshit I sent. lol. Quote Link to comment Share on other sites More sharing options...
JoseP Posted November 15, 2022 Share Posted November 15, 2022 Unfortunately my Klipsch 48 bar is still not powering on after replaced the power supply unit. Initially I mistakenly swapped + and - while connecting 5V. Would that might have caused any problem? Thanks, Jose Quote Link to comment Share on other sites More sharing options...

Well if it is not the fuse, see what Klipsch says troubleshooting through their motions. Plenty here just do a search here and and on google on the bar 48... @KevinB Quote Link to comment Share on other sites More sharing options...

Even Klipsch doesn't attempt these repairs. They just provide a whole replacement, if the unit is still within the warranty period. I wouldn't count on much support from Klipsch on this one. 1 Quote Link to comment Share on other sites More sharing options...
JoseP Posted November 16, 2022 Share Posted November 16, 2022 At this point I'm not sure if it's the fuse or something else. Will start with the fuse I reckon. Any ideas on how to locate, check and fix the fuse? Sorry, I'm not an electronics expert. Quote Link to comment Share on other sites More sharing options...

captainbeefheart Posted November 16, 2022 Share Posted November 16, 2022 Let me get this straight. To fix these units you guys are buying different power supply boards instead of fixing the one that's already in them? I suppose if you don't have the tools and knowledge to troubleshoot the broken one I have to say this is a pretty ingenious method albeit more expensive. The reason I think this is so amazing is that instead of more stuff heading to the landfill people are diy'ing a solution to get their gear up and running again. It shows that with some fortitude your average Joe can fix their own amplifier if willing - well and has a basic understanding of electronics and knows how to solder. Awesome thread!! 1 Quote Link to comment Share on other sites More sharing options...
newbie1952 Posted December 24, 2022 Share Posted December 24, 2022 Does anyone have a diagram, pix of how to wire the replacement power supply? Thanks! Quote Link to comment Share on other sites More sharing options...
Jaya Posted January 11, 2023 Share Posted January 11, 2023 (edited) Ordered my power supply off eBay and followed the instructions. My Cinema 600 came back to life. Wish Klipsch sold these power supplies as replacement parts. Mine original one only lasted 1 year.

Capri335 Posted January 15, 2023 Share Posted January 15, 2023 Hi everyone, I too like fixing stuff rather than chucking it away. I also believe that modern electronics are built to fail, that's why I like older cars!! Anyway I have been following this tread since before Christmas and thought "well it seems that easy that I'll just get the power supply". That arrived last week and following SixerFixer's instructions I got it all done. I thought that it had worked as I saw the power light on the bench but after putting it back in it place..... nothing. It's a bar 48. So my original board had NO power to it at all after testing (240v was there) no 24v no 5v. With the new power supply that I sourced from ebay the power is there for about 2 secs. The 24v is fine the 5v will only stay on initially then drops to 2,3v. I f disconnect the 5v then power remains at 5v as soon as I reconnect it it drops to 2.3v. This is telling me that something else has failed but I have no idea what. Can someone point me to what it could be? I don't really understand electronics, I do known how to solder well and follow instructions though! When I was a teenager (Mid 1970's) I worked for Orange Music(UK) wiring speakers and amplifiers. Thanks in advance. 1 Quote Link to comment Share on other sites More sharing options...
RayWatch Posted January 22, 2023 Share Posted January 22, 2023 Yay! I purchased the power supply module from Amazon and connected it according to the info found in this thread. My BAR48 works again! Thanks everyone! Quote Link to comment Share on other sites More sharing options...
Bwb Posted February 1, 2023 Share Posted February 1, 2023 Harold, I read your fix for the Cinema 600 soundbar using a usb charger to power the 5v rail on the PSU. Do you have any pictures of the repair and connections on the PSU? It would be greatly appreciated. TIA Quote Link to comment Share on other sites More sharing options...
