FYI, the other speaker had the same problem and I fixed it the same way 💯😎.
I used this technique and an old HP PS, and now my 5.1 lives again.
Thanks bud.
Glad to help
You're what we call a board-level technician. Nothing wrong with that, but it would have been worth your time to bring that simple power supply to the component level. Something made that resistor get hot, you could do it.
* Regardless, I came here to find out how you fished the main board out. I got so much more, because of your complete disassembly. Thanks man, kudos.
Hahahahah I not gona lie, you are right 😂😂, I was tempted to dig in some more but it wasn’t worth my time since I had a powersupply to replace it, dw next time
THANK U SO MUCH, I got a set for free because it was faulty, and now with an old laptop psu I can get it working, bless u. 💖💖💖
No problem mate, happy to help 💃🏽
Worked great! Thank you. I used an onn brand 19 volt, 4.7 amp computer charger and so far it’s working great. Got the Logitech system for $10 and the charger for $5. Not a bad deal at all lol
That's a great deal 🙌 awesome stuff
Great job bro, love the step by step breakdown of the troubleshooting process, and also your thought process. Keep it up!
Thanks at bro, 🙌🏽 people don’t realize fixing isn’t a to b it’s a to b c d ……. And the solution might be all the away at z
Hello, thank you very much for that video. My daughter faced exactly the same problem and I fixed it thanks to your video ! We were so happy to save that device.
Omg it's always great to hear when my videos helps someone 💃. Thanks for your comment and keep fixing 🙌.
You just got a new subscriber love this video, hope to see more electronic fixes on the channel ❤
Thanks a lot. Working on some more videos stay tuned.
The real solution is to replace two capacitors on that power supply on the power output side which go bad. I am currently dealing with this very issue and found a reddit thread of several people also with the same issue and one person finally realize it was just those two capacitors on it which is the same conclusion I came to when I noticed the bulging capacitors after a few hours of troubleshooting and pulling apart the volume pot to clean it and resoldering connections only for nothing to work. It's a lot easier and cheaper then just tossing the whole power supply and replacing it. I'm currently waiting for replacements I ordered which is a set of 5 so if I have this issue in the future I will have some spares on hand.
Thanks a lot I did the same test 'cause I've the same Logitech speaker problems. Gonna fix it now, Thanks for sharing your knowledge. Cheers from Mexico🤓
Awesome happy to help, remember to take all precations when wiring up even if is the dc side. Last thing you want is the box of catch fire. Other than that good luck and you can always DM me on Instagram if you need any further help.
@@JustBarran Yeah, I've used thermofit to cover everything. Also used a 19.5 volts 3.5 amp laptop charger. Thanks again
@@andresvega5476 awesome well you all set, and cheers from Trinidad 💃
Thank you.
🙌
Very nice Thanks
No problem 🙌
Liked the video! Very good! You've fixed the issue of that speaker. Well, there's one thing I want to try. I bought a DB9 RS-232 cable female to 3.5mm male (since there's scarcity on the shop for male to male) then just bought another RS-232 male to male then will use a soundbar model LP-1807 (detachable L & R) with R bar as main then control as bluetooth and main control speaker. Hopefully it will work xD Subbed!
Hey would love to hear how this works out so keep me updated. Adding Bluetooth to this would make it so much more valuable as a sound system
@@JustBarran Once I've received the cable, will test it out then get you updated xD
@@JustBarran Didn't work bro 😅 I think only analog speaker with rs232 will work and not the digitized ones.
my z506 got broken this week, sound cutting out arround 70% - 100% volume and I think it get worse everytime, now I can only play at around 20% - 25% volume.
already checked the mainboard and the cable, all looks good.
not yet check the power supply yet because it's kinda hard to reach, but thanks for your video that confirm it can be replaced with laptop power supply and I have some spare laptop power supply
No problem, just be careful power supplied tend to have a capacitors that store charge so try and discharge the unit before testing and let me know how it goes. Happy to help
I can see the same resistor looking... a bit fried. But I couldn't get either of the boards out. I was about to rip the box to pieces and fix it later. But now I know the boardremoval and voltage. So I can either fix the board of just change the PSU. Thanks!
Hahaha i know things like this does make people get frustrated. Happy to help
Nice work, you still have more stuff to fix hun
Don’t remind me
Did he just say he want to “ destroy that box “ 👀👀👀😂😂😂
No boxes was destroyed in the making of this video
Found this while my friends are trying to repair a Z506 power cord lmao
Hope it helped
@@JustBarran We figured it out, but it was more shocking to listen closely and realise you also in Trinidad 💀
I have these and after 4 years they have a clicking tick almost like static. I checked my drvers and all but it remained. The fix was to remove my memory and wipe it with a damp cloth. I have my tower on the floor and have carpet. Bad move....static creps in but once wiped they are all good. Outstanding speakers if you are a hip hop head and a gamer.
That's awesome. Yeah the problem would probably have been the sound card on the computer. These speakers work great
@@JustBarran Perhaps but it was the memory that held the static. The sound card had nothing to do with the speakers. If left on they do tend to get a hum or a click but yes great speakers but still disposable
I have one and the center speaker have some noise in the back ground and the sound is very low, do you know any way to fix it? I tried cleaning the input and the plug but did not worked.
Yes, you should post attempts as well.
Thanks Shawn, I guess it’s the Journey not the destination
Ya son como 5 casos que falla la fuente de poder en ese modelo de logitech. En mi caso reemplaze la fuente con una fuente de laptop sony, va funcionando como 5 años sin problemas. La nueva fuente la puse dentro del cajon del subwofer.
yea, thats what I did also, great minds think alike
for the algorithm
❤️ 🙌🏽
Hey nice info.
But I bought 2 sets at the same time, I paid $70.oo each at a computer show.
one has gone (kaput).
I have had them for a long time.
Don't think I'm gonna try this as it would cost half what I paid for the full set.
And time to put into it.
Thanks for your video as I was going to try to fix it, but think I'll save the time and get an upgraded set up. And go back to Klipsch, or set up with Atmos. Not sure yet.
Hahah that’s a great deal you originally got, but yea I feel you, sometimes the repair is not worth it. See if you can sell it broken or give it to a repair shop at lease they can up recycle it. A lot of people will be looking for the speakers or control speaker alone too.
Hey, I like your video.. what kind of Hp power supply you use..?? Is the normal one 19v and 45w comes with laptop..?? 🙂
Yea it was a standard old time charger, 19v about 3A
Great video man, can you tell me how can i find the potentiometer on the controller speaker(volume control)
It is a dual (double) 20 ohms potentiometer i believe, A 22 will also work. It looks like this. store.comet.bg/en/Catalogue/Product/25571/
@@JustBarran thanks much appreciated
Hey bud, great video! I happen to have the same speakers, and with the same exact problem. Even have an old laptop power supply I can use. Just a quick question to clarify, you skipped really fast on the wiring and connecting the wires from that laptop power supply to the DC wire that connects to the board of the speakers. Any chance you can explain a bit further how you did that exactly? Would be greatly appreciated.
Hey no problem man. Sorry It was too fast. Not sure if you have a multimeter. But make sure the laptop powersupply is around 15v to 19v. I cut out the end from the laptop charger. This is the side that would have gone into the computer. On the AC to DC supply on the speakers. The little circuit board I threw. There should be a red and back wire that plugs into the main amplifier board. I cut that wire and spliced the red (positive) to the positive of the laptop charger. And the negative(black) to the negative of the laptop supply. Use a multimeter to make sure which one is positive and negative because laptop chargers vary the voltages. I put some heat shrink also before I did the splice and added solder after to finish it off. Then I pushed it Through the hole that the original AC plug would have gone thru. Tied a knot so it doesn’t pull out and fill it with glue stick. The I plug in that to the amplifier board and you should be set.
@@JustBarran Nice one dude! Thanks a lot for the info. Wish you all the best, and happy projects! :)
@@MeTr01DPr1M3 no problem, let me know if you are successfully
@@JustBarran Hello. How many volts and how many amps does the adapter in it use? What power supply did you use? What value did you use?
@@abdulllah01 I not sure what are actually specification of the powersupply that originally came with the speakers, I believe from looking at the components it could be around 13to16v 5A , I replaced it with a hp laptop charger which output 19v 6a I can’t remember exactly cause I gave it to my friend.
Nice wood smell, can we get that in a candle form?
I would give you a candle with the smell of my wood 😂😂😂😂
Christmas gift that keeps giving 🤦🏽♂️🤦🏽♂️🤦🏽♂️🤦🏽♂️
Eehy watchu ylknow about di Lofi gyal?? 😂 Great job my fellow ee/me engineering coop!
I actually received these speakers today wuth the understanding that they dont work. On a preliminary test, I observed massive heat on the DB9 control cable and no output sound on the control speaker. This has to be a dhort- no?? Do you think that could be a short either on the output stage or the right speaker?
Hmmm heat on the db9 seems weird, yet it definitely means something shorting but also that should be a low voltage circuit. I would check all the connectors because that is serious weird
I blowed up my multimeter once by measuring AC voltage with DC set on it 😂😂
Sorry to hear that 😢, but yea making sure it’s set correctly is really important
Don't be sorry for that !! Actually it was funny at that moment
You can "blow up" your multimeter if you measure on the "ohm" setting and there is volts in the circuit though..
Do you know how to fix the part where you plug in the speakers to the subwoofer? Cause the right front(black) female connector on the subwoofer is only making noise or static when i hook up my speaker.
Sorry I returned the speaker to the owner, so I really can't say.
I have this speaker set and I wonder whether it's something that I could make battery powered? Perhaps a laptop battery and power supply?
Hey, definitely I think that’s a good idea, you could also get a Bluetooth module also. In terms of battery it would need to have a decent capacity depend on how long you wanted it to play for. The speaks are DC so you just need to flow the video , but where I change to rectifier /power supply you can substitute that out for a DC jack and feed the speaker of a 12-19v supply /battery and you should be good.
Hello. How many volts and how many amps does the adapter in it use? What power supply did you use? What value did you use?
I not sure what the Original one was, I believe it could be 13-15v 4A around there, the one I replaced it with was a ~19v 5A hp laptop charger. Anything around the should work
You should probably get that drill checked out... I heard there's medication to help with that o.O
Yea I going “straight” to the the doctors 😂😭
Hello, do you know if it's possible to modify this subwoofer for use with RCA input without the control speaker? I acquired the subwoofer by itself and i'm looking to see what I can do with it.
It should be possible since the control speaker doesn’t do much other than put on the amplifier and set the volume. It would require getting a pin out for the DB9/rs232 connector and making the required circuit. Check out this www.yoreparo.com/es/audio/audio/preguntas/1250316/logitech-z506-control-de-volumen-db9
@@JustBarran Thank you.
No problem
Hello can a Logitech Z313 Subwoofer Speaker work in the Logitech z506 subwoofer as a replacement ? trying to find out online but it's really difficult
Am not sure sorry.
Speaker watt and impedance should be match otherwise it would be damaged to speaker or amplifier.
So replacement subwoofer should be 25-30 watt max and impedance should be exactly equal.
It should be between 20-30 watt,
Don't play bass volume at max.
Use 60-75% bass n volume.
IT won't be damaged.
can I connect the z520 speakers to thr Z313 woofer, Bcos I want more bass in my sound
Am not sure to be honest
Watching this video cause I have a 7 year old Logitech Z506 which i bought from supertech in puna for $550 and still works perfectly. And I recently saw on amazon for this same brand goes for $264.64usd 🤣and the Logitech Z906 for $399.00 . So I have a damn expensive system in 2022. So I was just looking around to see what is the type of issues can occur and how to prevent them.
Thanks for watching 🥹
@@JustBarran not calling anything on my speakers but if anything goes wrong i know where to go 👍
can make video to open z506 center speaker?
Sorry this was a repair for a friend, I don’t have the speakers anymore
hello, I subscribed to your channel, I have the same problem, but I don't know if I can use the old Lenovo 20V 4.5A power supply?
Hi, this one I am not sure about the 20v might work but it would be risk. I most I tried was 19v
@@JustBarranwhat exact power supply model did you use?
@@damiantobaj5977 18.5V 3.5A 65W HP Pavilion DV4 Power Supply
@@JustBarran I bought the same one, I haven't cut it yet, but which cable is + and which is - in this HP power supply
Hi, this would be different between models but I recommend using a multimeter to check this.
Hey, the sond emitting from my speakers sounds like it's breaking up and sounding distorted when the volume is proberly on only like 35%. Don't know if it's the speaker ffrom the box
or something else. Could you give some advice. Thanks
Hmm not sure to be honest. Distortions come from noise or a bad component in the amplifier
@@JustBarran I should have clarified b4. It's the logitech z506 speakers. The distotion is coming from the bass box. I think that the speaker is blown but I don't know if it could be something else. I disconnected the speaker but got the same result. Don't know if it's another component that has malfunctioned.
Hello! Bro, my master speaker from my Z506 is "broken" according to the technician. He told me that I need to buy the master speaker, BUT that is not in amazon or any other website for me to purchase, or is it? Can the cable be fixed? Please answer. Greetings from Panama!
Hey Robert, when he says it is broken does he mean that the power supply is broken like in mines ? Or is the speaker with the knob broken. Because as in the video you can also try what I did and change out the powersupply with a old laptop powersupply first. If the power supply is broken the. The master speaker would not work also
What are the values of the adapter you plugged in? Is there any problem if I use 12 volts and 3 amps?
The 12v isn’t enough because amplifier is rated for higher voltages, I think 12 may still working but it would affect the maximum output volume among other things
@@JustBarrani get a very wierd doing with 18v, is it normal?
Hi, should I use 15v 5A adapter or 19v 3.2A ? I appreciate your response, please help me choose don't say they're the same. lol thanks
Hey ether one will work, the 15v 5a is closer to the original powersupply so try and see if it works first and how it sounds. The only reason I used 19v was because it was what I had available. So if you have had to chose go with the 15V as it is more with in the original specification
@@JustBarran thanks man I appreciated it, and yes it works like a charm! But now I have other problem the potentiometer is broken because I forced it without opening the screw at first lol..
In one of the other comments on this video I give someone the link to a replacement pot, ask them if it worked
Are you using 15 v.??
I think it will be safe.
I replaced with 12 v but can't play at max volume
IT play well around 70-80 % of total volume bass.
Reply if 15v is working well.
I tried to open mine, but both the control speaker with the buttons, and the subwoofer panel are glued inside. There's nothing wrong with it, except i want to see if I can turn the whole thing into a passive speaker system, since the *ONLY* 5.1 HDMI ARC decoder on the market has an internal amplifier. Yes, there is only one such product and it's discontinued. These are just remaining units. There are $2000 audio mixers that support HDMI ARC input, but that's a professional studio system with about 30 I/O ports of various kinds.
Hmmm good points it would be something I have to look deeper into myself and get back to you but at that price it that audio mixers are nt worth it
@@JustBarran Update: I managed to get the subwoofer open and adding the new direct input was easy as soldering two wires to the speaker, then on the input port, drilling a hole and gluing it there with hot glue.
Also on found which two pins in the DB-9 go directly to that speaker. When looking at the RS-232 layout as reference, pin 6 is the signal + line and pin 7 is ground. Got a DB-9 connector wired to an RCA jack and it worked as expected. The whole system of course is unplugged from power. Don't want to know what will happen if I turn that on.
@@coladict did it work?
@@JustBarran The new inputs work. I haven't tried the old ones, because my 5.1 optical audio decoder is has a buffering issue. The longer I leave it on, the bigger the audio delay. It reaches a full second of delay within just 2 hours.
@@coladict dam that's a big delay, hope you get a work around
How do I connect the speaker with a laptop power supply board ? Not sure how it works 🙏🙏🙏
You have to take out the old internal power supply and by pass it
Can I bring my speaker to fix as well?
Depends is it a Logitech?
Mine also got an issue with the centre speaker low sound. Compare to others
Not sure about that sorry
Is it normal that we don’t get a a clear sound? I can’t really enjoy my music with this solution, I get a dirty sound I don’t know it it because of the power of others
Nah, something else might be the issue. The sound on the one I deliever was clean. It could be noise from a bad power supply used, bad input connection or cable or bad sorce. I recommend try the input with another speaker and seeing if you hearing a similar sound. If not it could be one of the ampliers for damage from the original failure of the powersuppply
I tried this with an 19v 3.42a charger, the speakers turn on for a second but then the energy fades away and wont turn on until I disconnect the laptop power supply... Im not sure what im doing wrong :(...
The charger says it is INPUT: 100-240V~1.6A 50-60 Hz OUTPUT: 19V 3.42A
Do I have the wrong values for my laptop PSU? Thank you in advance!
Likly that the laptop psu Is detection a high current spike and going into protection mode. Check and make sure their isn't a short circuit any were or that the power supply is not faulty
will bluetooth connection allow surround sound (all speakers will sound?)
Yea these speakers don’t do directional processing so what ever Input you put in would be equally play the output (L and R)
Thanks again. I will try getting a Bluetooth adapter.
Hiibro my Logitech z506 model 5 days working next day not working rear or left speaker very low volume problem telme solution bro
Could be the speakers them selfs
is it better to use 19v laptop adapter or 15v ?
I don't think it should matter, I believe the original one was around 15v, once the current is around >2A
@@JustBarran thank you for your response, I was just wondering if using 19v will create a static or noise?

Hey the video sloved the issue
como le añadistes el blutoo
I used an external Bluetooth adapter
My systems keeps playing and cutting off repeatedly... don't know what's the problem?
Could be a number of things from a faulty cable to a bad power supply like in the video. Would be better to see if you can isolate the cause of the problem,
Eg it cut of when you move the system, or when you try to play it too loud. It could also be a switch shorting out
Mr. Barran: I don't see the interesting part of what you buy. We would like to learn not only electronics but to program Arduino building anything useful either for home or for industry. Still, thanks for your input.
