Trying to Fix My Logitech Z333 2.1 Speakers (One Speaker is louder Than the Other)
ฝัง
- เผยแพร่เมื่อ 2 พ.ย. 2019
- An issue I have been having with my Logitech Z333 Speakers for the past few months is that the left channel of audio is noticeably quieter than the right even when I play audio that is mono and balanced centrally. This should not happen and both speakers should be equal volumes in this scenario… But they aren’t; time to investigate!
In this video I will demonstrate the issue, diagnose what’s causing this issue, and then attempt to fix it, will I be successful in this? You’ll need to watch the video to find out.
*This video is very long compared to my other videos as I intended on making this a 2-part series, however, after reviewing the footage there wasn’t a good place where one part could conclude and the next part to begin, so I changed my mind and put it all into one video. - วิทยาศาสตร์และเทคโนโลยี
I'm having the same problem. So surprised others do too! I thought Logitech had good stuff
same
it has good stuff
just the quality controll sucks
i have had these speakers as my daily frivers for 2 years now
despite me driving them crazy and possibly overvolting them(and overwatting them) the just are clear as ever
(occasionally clipping a bit)but the get to 140w from 80w
so it can draw a lot more power safely that its recomended
i usually go into windows audio settings and turn one up louder if I had to fix it
I have a problem, I need to shake and hit the base for them to turn on, what could it be?
I was going to try to fix some connection issues on my Z333 but seeing this video made me drop that idea. Not only do you have to take apart the entire sub to get out the little control board but the RCA connectors are like a full-on assembly? Probably not worth the time and effort for a $50 sound system...
i have a trust tytan 2.1 speaker set and i have a problem with the volume control thing that has 2 aux cables + 1 3.5 mm jack when i turn it to max volume it switches speakers so one becomes louder than the other
Same problem here: black output volume worked fine, blue output volume was very very low regardless of which speaker was attached. My problem was the potentiometer underneath the volume knob. It was not outputting the same resistance for both left and right speakers.
At 8:52, you can see the white 7-pin clip coming from the volume knob/pot. The resistance between VOL_LOUT and GND and the resistance between VOL_ROUT and GND should be the same at any specific knob position. Seems they should scale between 0 and about 12-14 kOhm as the knob is turned from 0 to 100%. My VOL_LOUT maxed out at ~25 Ohm for 10-100% volume, whereas VOL_ROUT output the whole 12-14 kOhm range. I was able to fix it simply by blowing compressed air into and around the pot in the middle of the PCB at 30:21. Seems to have been weak contact in the pot or it's wearing out...
Hopefully this helps someone.
Works here! Thank you soo much
Works here too! Thanks for sharing your solution.
man exactly the same but here the blue output broke both my speakers from my old z333 and my new z333
both speakers just sounding horrible now, no clue what the blue output did to the speakers :/
running 1 speaker only
Just took mine apart. took the connector out and gave a few good turns on the pot and all working fine.
Thanks for pointing in the right direction.
Thanks you so much much ! I had tried to dismentle de back pannel but couldn't and was so frustrated ! Now I'm so pleased with my two speakers blasting ! (it was the Left output aswell)
I have the same speakers, when I opened it up I noticed the glue, and took some of it off. However my fix was to push in the black box that holds the audio jacks into the PCB. For some reason this was one of the only things that didn't have glue on mine, but yours did despite being the exact same model.
Mine doesn't give out any audio at all..
The problem is with the connectors in volume control pcb..
Logitech sucks!!
Had exactly the same problem, i just hammered the right outport a bit. it seemed to fix the issue
how about 1 jack with 2 speakers that are connected and only the right is working?
Does Logitech have a repair place somewhere? Can you get one fixed if it goes bad out of warranty? The price for them now is $99 on amazon. Maybe I could get my right channel to sound, cheaper by them fixing it rather than having to buy a whole new one to replace? Does anyone know where to get repaired?
I had no sound in left speaker, the first thing is to try look is at the connector for the speaker that has no sound, squeeze the connector inwards so it makes harder contact with the output on the sub-woofer box's amplifier board, the connector is loose and making poor contact with the amplifier output connection. if that doesn't fix it than you must unscrew the amplifier board and check for loose capacitors, you must reflow the solder because the capacitor solder joint has broken loose and is making poor contact. mine is fixed now
im having the problem , when you adjust the volume i can hear that noise and its annoying
Hey today I came with the same problem.... Any help?
How do I know if it’s happening
I've bought this 2.1 Speaker set as a christmass present. I would like to know, is if this problem had occured some time later of using it, or when it was brand new connected to PC and started acting weird?
Thanks for watching, with me, the problem occurred sometime later after using, but I've had other comments saying their speakers suffered from this issue when brand new. I think it's hit-and-miss with this issue.
When I still owned the speakers, I disassembled the volume control and cleaned the PCB and volume potentiometer which fixed the issue temporarily, but it always returned and eventually, I decided to replace them (and made this video too).
they glued the connectors since lots of people were complaining there system stopped working and its due to the subwoofers vibrations that get sent out and moving the connectors out of the place
you tried your best but when i saw the glue was thinking they had a reason to be there.I think because of the vibration from the sound that might be an extra security step to make sure they don't get lose.but the 2.thought i had was it might be because they want to prevent someone takes it in apart.good that i know now for what to look for NOT to do.
my problem is the right speaker is not working, there is no sound or anything. I dont know what to do with the right speaker
I had no sound on right speaker. The problem was on the headphone jack. There is a switch inside the jack that de-activate the speakers, move it with a toothpick and problem fixed some contact cleaner may help too.
GRACIAS!!! ME FUNCIONÓ, MUCHAS GRACIAS AMIGO, yo le puse unos audífonos sin meterlos hasta adentro y de funcionaron! :D
now the new problem is that it gives me Mono audio, with you is the same?
How do i move it plz respond and where is the de activate in the 3.5mm
RAFADABO55 When you insert the headphones there’s a tiny tab inside that disconnects the sound to the speakers. I manage to move it and it worked for a while. I ended removing the headphone jack and soldering small wires between the terminals in the board.
@@j.r.cabrera5813 so i put a little toothpick into the headphone jack?
I had a similar issue with my Logitech Z337, but it was only present when the volume was set approximately to a quarter or less.
I took off the volume control knob (just pull it out, don't be afraid to use a bit more force) and sprayed a little amount of WD-40 into the potentiometer. Then I rotated it a few times for the oil to settle and the issue is gone now!
Also, when I was turning the volume knob, the speakers were cracking, now this is fixed as well.
Good tip! I also experience the crackling, I believe it's caused from dust/debris inside the volume potentiometer which interferes with it's function.
I had the same problem with my Z337, the issue was caused by the potentiometer in the volume wheel which was internally become dirty (also oxidized maybe).
I solved the issue desoldering the potentiometer (with a desolderer and the soldererer with a copper desoldering braid), opening it and cleaning the internal circuit traces with alcohol, I also cleaned and bent a bit the internal brushes so they make better contact.
It's not too difficult if you have some skills doing these type of things.
In this way I also fixed the "scratch noises" problem that occurred when I rotated the knob, now it doesn't make any annoying sound.
The potentiometer is called (I think it is its name?) B503 and it has 6 pins. I found similar ones on Aliexpress for a few bucks and I ordered them, if the problem occours again I'll try them
i have the z533, the right speaker stopped working, I unplugged the AC, double checked for no power and felt a loose capacitor, touched it with a screwdriver and used that to straighten capacitor. seems to be fixed
how did you open the knob to access the PCB for the z337. I tried to snatch the top out but nothing came out as easy as shown in this video.
Iam having probably same problem here, but iam scare to soldering that...
I think I have figured it out. I had the same problem with my right speaker very quiet and the left normal volume. When I had only the right speaker plugged into the subwoofer I ended up bumping the 3.5mm jack that connects to the back of the computer. It suddenly got louder. I continued jiggling the jack and the volume changed up and down accordingly. So for mine, the wires in the PC jack must be damaged. Cheers
worked for me. the subwoofer was hitting the wall because it's placed too close into it. made some space then tipped the wire a bit and that fixed it. thanks man.
i cleaned mine all the outputs and it miraculously fixed
How
@@jeffcleds I think I found the fix! I was using the 3.5mm jack from the speakers to the desktop PC, When I bought an RCA to 3.5mm adapter both speakers work. the speakers have 2 input types, 3.5mm and RCA left and right output. use the other one, something inside the speaker has failed
@@eksine I have tried this fix but for me it didn't work. I'm afraid I have to solder the connections on the board. I think Logitech have to improve their quality checks on their products.
I had a similar problem, what i did I bought RCA plugs, cut the cable, put it into the new plug, and my sound went back to normal. edit: I cut the old plugs open andthe left one it seems that the white cable wasn't soldered to the plug properly, it was barelly scratching the place where it should be soldered. that's why new plugs helped.
mine has a crackling sound when i move the 3.5 mm cable. does anyone know of an easy way to fix it
that's normal, it's because you need to turn off the speakers before you disconnect, if you understood how speakers worked you would know
I have a logitech Z337 and my sound stops at low volume after a few minutes
I am so angry on logitech
The glue on the green board looks like somebody sneezed on it!
Anyway, it's pretty frustrating that this video didn't tell me how to fix the issue, but at least I got to see inside my speakers. I probably won't try any of this because it's happened before and the left speaker (on mine) always comes back on again eventually, but I can't believe they make it so hard to dismantle, considering how often this problem seems to happen.

2023 Logitech still have this issue just bought a new speaker set and plugged it into the subwoofer and still one is louder then the other
Im having the same issue right now.
Did you fix the issue?
@@evenus3044 No. I just bought a new one XD
@@evenus3044 i have the z533, the right speaker stopped working, I unplugged the AC, double checked for no power and felt a loose capacitor, touched it with a screwdriver and used that to straighten capacitor. seems to be fixed
@@eksine Lol, same. two capacitors were bent, I just straightened them and everything works like a charm again :)
@@dejanzvonar9187 i ended reflowing the solder to the caps, it worked for a while but still getting the same issue, 1 speaker cuts out, replugging the audio input fixes it but it goes out as soon as the pc goes to hibernate. maybe the caps need to be replaced or maybe its a bad microprocessor. its a huge shame, these sound good while both side work. i could just bridge the wires to both channels so at least i have both working again
My speakers are fine my subwoofer doesn't work at all.. They glue the connectors so they can tell if you've tampered with it under warranty.
I guess I’ll just buy a replacement subwoofer on eBay, sounds like a good idea? They’re only 30$
my blue output doesnt work ata all on the subwoofer the speaker are fine tho
maybe a dumb question but, is the big one supposed to give off sound as well? because mine has been very very soft.
@@FrazerForbes1 oh okay, i alwayd have the bass turned all the way up. So the big one is mainly for bass then?
@@MZeuSD the big one is called a subwoofer btw
@@darcyy3807 oh ok.
Had the same problem, usually just putting the volume at max and then thouching the head of the 3.5mm plug with the tip of my finger repetidely did the trick, this time that was not enough
Had to touch the pins on the back of the white conectors (why are they glued lol), specifically the one for VOL_ROUT seen in 8:54, which is the 3rd one from right to left seen in 10:34, fingered that little thing a couple of times, each time i touched it the sound changed in timber, until eventually it came back to normal
You need to make a come back Frazer!
My blue input doesn’t work, any advice? Both speakers work in black input but neither In the blue
same , need help
omg, Ijust bought mine Z333 and have the same issue... :/
i would like to help you as i fixed mine, but i dont know the words for it...
@@wolfy4278 was it too complicated or an easy fix?
Shako Winter complicated , i had to destroy the cable that gets into the pc and look inside it, inside i found an cable that comes from the second speaker so that means the cable was broken and thats why. i fixed it with some adesive band or some thing and then plug it back in and it worked, if you want i can give you my discord and show you exactly
same exact problem
i thought it was my speaker jack being damaged
I'm having the same problem. Bought them 2.5 years ago.
i have the z533, the right speaker stopped working, I unplugged the AC, double checked for no power and felt a loose capacitor, touched it with a screwdriver and used that to straighten capacitor. seems to be fixed
my subwoofer isnt working :c
im not taking mine apart ive just turned my volume in the balance tab on windows for the right channel to 50% and gave up there lol
I have the same issue with the Z337.
same here :(
did you fix it?
Change the capacitor behind the port. The 1000uF 16v
No funcionó
thank you you are the my superhero
@ArdieBacardi its the e color :green pink and blue (should be) insert the pink i trier its happened
I lose power in the R speaker because pcb afer 3 years.

i am having the axact same problem
Or you could get a 2 Male RCA 1 3,5mm Male cable and connect it in the back of the sub... just sayin...🤷♂️🤷♂️🤷♂️
@@FrazerForbes1 ❤🥰🤩
I tried this on a Z533 where the right audio output does not work. Changing from 3.5 to 2 male RCA did not change the output channel issue.
good I watched if it worked at the end xd
I have the same problem
Look at the bloody glue!
o.0 Why it Do diss?
i just slapped the fuckin subwoofer and it works :D
BTW; DONT TOUCH THE STUFF YOU SAID WAS GLUE! IT MIGHT BE ACID
the problem is logitech they fkin suck with those stuff brand new ls21 same problem lol
My left one is ok. Right is not loud enough. I inverted the cables and determined is not the speakers. What a piece of shit.
try using the rca output instead of the 3.5mm jack, fixed my problem
@@eksine Thanks so much, your comment saved me the trouble of tearing it apart myself!
@@eksine that's isn't working in my case, what shoould i do?
My right speaker was louder than my left, but I finally discovered what was wrong. Because of the position of my subwoofer, I decided to switch the connectors and then switch the position of the speakers. I didn't think there'd be anything wrong. Turns out connecting the right connectors to the right sockets solved the problem. Basically blue goes into blue. Black goes into black. Or else the volume imbalance problem occurs. This comment is only for those who made the same mistake as me.
Last time I ever buy Logitech crap.
You were no help at all
