Logitech z506 Speaker Repair | Fix-it Friday #2

[@JustBarran]

FYI, the other speaker had the same problem and I fixed it the same way 💯😎.

[@jimrankin6634]

I used this technique and an old HP PS, and now my 5.1 lives again. Thanks bud.

[@JustBarran]

Glad to help

[@OnHoldAt50]

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.

[@JustBarran]

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

You save my birthday, tomorrow i make a party and i fix my z506 with this metod! Many thanks!!!

[@enforcedraccoon8648]

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

[@ZikiDwiJR]

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

[@JustBarran]

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

[@waiora_wf]

Same speakers started out with a slight buzzing sounds, when it was cold in winter time the buzzing would be worse if speakers were off and eventually fade when using them. After a few years the buzzing stopped but speakers started cutting out at 30-40% vol. Woke up one morning with power tripped and when i switched everything back on, the speakers were just dead.

Hahaha i know things like this does make people get frustrated. Happy to help

[@triplemmenace]

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

[@JustBarran]

Hmm not sure to be honest. Distortions come from noise or a bad component in the amplifier

[@triplemmenace]

@@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.

[@edgardominguez9081]

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.

[@JustBarran]

Sorry not sure, a number of issues could be causing that , could be short in the wire also or a bad transistor on the amplifier

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

[@JustBarran]

Am not sure sorry.

[@escapethematrix5379]

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.

[@escapethematrix5379]

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.

[@dennisacheampong4910]

can I connect the z520 speakers to thr Z313 woofer, Bcos I want more bass in my sound

[@JustBarran]

Am not sure to be honest

[@oOPaiNOo14]

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.

[@JustBarran]

Sorry I returned the speaker to the owner, so I really can't say.

[@adityam8888]

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

[@JustBarran]

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

[@adityam8888]

@@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..

[@JustBarran]

In one of the other comments on this video I give someone the link to a replacement pot, ask them if it worked

[@escapethematrix5379]

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.

[@BlindMellowJelly]

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.

[@JustBarran]

That's awesome. Yeah the problem would probably have been the sound card on the computer. These speakers work great

[@BlindMellowJelly]

@@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

[@ThePeterasd]

will bluetooth connection allow surround sound (all speakers will sound?)

[@JustBarran]

Yea these speakers don’t do directional processing so what ever Input you put in would be equally play the output (L and R)

[@ThePeterasd]

Thanks again. I will try getting a Bluetooth adapter.

[@LindellHarry]

You just got a new subscriber love this video, hope to see more electronic fixes on the channel ❤

[@JustBarran]

Thanks a lot. Working on some more videos stay tuned.

[@buhuhuh7757]

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?

[@JustBarran]

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.

[@ShooterQ]

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.

[@JustBarran]

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

[@Haldrie]

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.

[@JustBarran]

I check the caps on mines and all were fine. I just reach a point where I weight the time taken to find and fix the bad components or spend just replace it with something I already had lying around. I went with the lather. Sorry that you reached the same place 🤣

[@drumreach5940]

[@MeTr01DPr1M3]

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.

[@JustBarran]

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.

What are the values ​​of the adapter you plugged in? Is there any problem if I use 12 volts and 3 amps?

[@JustBarran]

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

[@coladict]

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.

[@JustBarran]

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

[@coladict]

@@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.
