Logitech G603 Scroll Wheel Fix (+Full Disassembly)

[@AustintheJLman]

Update November 2022: Unfortunately, my scroll wheel encoder outright failed on my mouse. The fix was still working, but for whatever reason my encoder stopped working. I hope this hasn't happened for anyone else, but if it has I ordered this part from eBay and my 603 is good as new. I followed the same tear down process I showed in my video and did not install plumber's tape as I replaced the entire encoder. Hope this helps anyone who continues to have issues. www.ebay.com/itm/283820012778?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=qfdc9QT9Ri-&sssrc=2349624&ssuid=fltuEjuIShK&var=&widget_ver=artemis&media=COPY

Your mouse encoder was probably fine, those things apparently oxidize over time from sweat from your fingers. I've cleaned mine with WD-40 contract spray and it works like a charm, probably this will work with king of contact cleaning spray. Hope this helps a lot of people. In general the hole does not get bigger overtime, so probably the teflon tape fix, does not solves it at all.

[@juanblockman9924]

I think mine is bad because the white wheel that has teeths is worn out. It also has a little metal ring which marks the steps.

[@DanielSylveste]

@@DenisGeorgiev You are absolutely 100% right. The problem is just oxidation and dust inside the rotary encoder which is not encapsulated. Contact cleaner and compressed air fixes the problem in 5 seconds and you don't even have to take apart the encoder assembly.

Glad I watched the video all the way through before I started taking mine apart, gotta go get some thread tape, I'll update this comment once I try this fix. POST REPAIR UPDATE: It works! I used it to scroll to this video and comment! The repair was surprisingly easy, I used the screwdrivers from a small Glasses Repair Kit that I had and they did the job nicely, I can say for certain that the scroll is now completely fixed, though the thread tape does make the scroll wheel a little stiffer to spin, its not a huge difference. One thing I would like to point out, is that during reassembly, the tan ribbon wire that goes into the scroll assembly itself has a specific slot that it goes back into on that receiving connector, it is potentially difficult to figure out if you don't know what to look for, but otherwise, reassembly is just as easy as disassembly, just be careful not to strip the faces of the screws.

This method is so much better than another video I saw, which used paper. Thank you!

[@misterluquinhas]

Thank you! This fixed my Logitech G603. Had this problem for a while. Glad that I had everything to fix it. Used the same tape as you but a little bit smaller. Didn't disconnect the beige connector as I didn't want to take the risk of breaking it.

[@valentina8999]

This method really helped fix the “backscroll” problem. Thanks for the video! The scroll wheel started spinning only in the right direction. What became different: the wheel spins a little more tangibly and you have to press harder on it to click the mouse wheel.

[@pjuppi]

i bought that kind of tape years ago but haven't had any use for it, now it came to use! works really good and i actually think the scroll feels more sturdy now 😄

[@jackychan7511]

Thanks so much! I didnt have this problem but for me one of the sticks on the side of the scrollbutton broke off so I couldnt scroll. Because of this tutorial I could find the problem and glue it back together and now it works again!

[@zyblack]

It worked for me too. Just a note that there is no need to remove the 3rd connecter (the beige connector written on screen) as I could do all the steps while leaving the connecter untouched. Thanks!

[@AustintheJLman]

Hi! This is correct. You would only need to remove that final beige connector if you were to replace the entire scroll wheel encoder. Thank you for pointing this out!

[@juanblockman9924]

I just disconnect the first one

[@MarcosAntonio-rt5vz]

quick tip: you dont need to remove the delicate cable on the left, just the power one and then lay the upside part of the mouse at side while you do the fixing

[@Edson-Lima]

Thank you Austin! It worked for me too, but I used a little different approach, since my well support was broken.

Thank you!! I was going to buy a new mouse, but I just try this and it worked perfect my mouse is working just like new!!

[@thedarksoul1993]

Great video, it actually worked. Nicely done!

Man, what a good video! Just thinking of replacing my mouse and it worked really well!!

[@liameyskens722]

YOU ARE THE GOATTTTT!!!!!!!! Thank you sooo much for this tutorial!!!

[@igalporat4855]

Great video, saved my G602!

[@tryofahuman9536]

love you bro, i almost bought a new mouse

[@alexyz78]

Thank you for this tutorial! I fixed my mouse.

[@kubotwostringz]

Yo! thank you for making this, friend. I managed to fix my "jumping" wheel behaviour on Logitech M190. Take care

[@lucasdiaz5060]

Best video, repaired my g603 in 20 mins, thanks man!

[@AleStronz]

Dude, thank you so much, fixed it with your video many many thanks!

[@overparser]

It works. I'm just removed hairs on the wheel and that was enough

[@gomeshes]

Thank you very much sir. You are a legend.

[@overproof1460]

Thanks so much!...I used masking tape though & it seems to be working so far.

[@overproof1460]

masking tape wore out after a month...gave me enough to grab some plumber's tape. so let's see

[@JQWojcik]

Hi, very useful video you hleped me so much, it worked for me so i belive it will work for you guys too

[@sandrvoxon]

Thanks. Because of your guide I’ve broke small white piece !

[@nibbid]

thank you!! you saved my life

[@bartekltg]

The inside of your mouse is much cleaner :)

[@2GUISSOS]

It worked for me! Thanks!

[@drunkmosquito4834]

Fixed mine. Thanks!!!

[@lucasquaroni3120]

Fixed! Thanks!!❤

[@Crotalus206]

works perfectly

[@Math_0027]

Will this fix scrolling sometimes not registering? Also does this make the scroll wheel feel heavier?

[@AustintheJLman]

Not registering may be an encoder issue. Mine did not feel heavier when I applied this fix.

[@iniciativawayze5093]

Muito obrigado. Era o que eu estava procurando.

[@juanblockman9924]

Aun te funciona el mouse ?

[@rafael_luz_rodrigues]

Hi, after how long of use did you have to do this? I bought one but it hasn't arrived yet, but I bought it aware of this problem. I hope it happens after 2 years as that's when the extended warranty ends.

[@AustintheJLman]

Mine lasted about 4 years I think but it could be different for each person

[@krymtON]

I have same issue. My question is - what cause the problem? Was the gap between the scroll wheel and encoder? If so, wouldn't it be better to use hot glue/superglue instead of tape? :) Any idea?

[@DanielSylveste]

Problem is caused by oxidation of the contact surfaces on the rotary encoder. Can be fixed in a few seconds with contact cleaner spray. This "fix" instructed in the video does not fix anything. Just buy a can of contact cleaner spray, open up the mouse (no need to disassemble the rotary encoder), spray the encoder with cleaner, scroll the wheel for a while to both directions, and you've fixed it.

[@yanke_s3016]

Works perfect for me

[@IL4NCER]

What if the cilinder broke between the wheel and encoder?

[@AustintheJLman]

You will probably have to replace the entire encoder. See pinned comment for the one I bought when mine completely failed.

[@IL4NCER]

@@AustintheJLman i tried to glue it but you need to have surgeon precision to do it right, kinda worked but later replaced it with a new one

[@navossoc]

If I scroll down, sometimes it scroll up a little bit too... Anyone managed to fix this?

[@AustintheJLman]

That is what the tape aims to fix. If this does not work, you may need a new encoder. See pinned comment for the one I purchased for mine when it failed completely.

[@navossoc]

@@AustintheJLmanYeah, the tap didn't fix... I think I need a new encoder. Anyway, this is my 3rd g603, so I took one scroll/wheel from another one. Thanks.

[@colig54]

worked thanks

[@mastermode]

Do this before. Just turn the mouse and let the mouse wheel roll on the mouse pad for one minute.

[@pisitmeegrud5544]

THX SO MUCH!!!

[@enso8762]

Why does logitech scroll wheels always break like this?

[@CEAG23]

gracias!!

[@redzcoleto5078]

I lost my usb dangle, is my mouse going to waste or I can do something please help.

[@AustintheJLman]

You would need to request one from Logitech I don't believe you can buy them but search ebay.

[@avia4281]

I tried but not work saw another video where you use wd40 and a heatgun to dry it out and works like new.

[@xinao]

that string of hair was driving me crazy

[@11elie09]

Can't believe I have to do all that just to access the wheel... Wish me luck 😭

[@AustintheJLman]

Hello! Yes it is a pain. I actually took mine apart again and found that I really only needed to remove the ribbon cable at timestamp 2:40 in order to access the wheel. I took all the way apart in this video to be extra cautious of damaging tiny cables, but looking at it again I didn't necessarily need to. The top half will just hang off the side from the red and black wires. Good luck!

[@m1m014]

[@Mateus01234]

Os cara usando fita veda-rosca pra consertar mouse KKKKKKK Mas se funciona, é o que importa.

[@DanielSylveste]

WAKE UP! THIS DOES NOT FIX THE PROBLEM! Only reason why this migh work for a while is that while manipulating the scroll wheel (taking it off and pushing it back in) you move the contact surfaces of the rotary encoder in which the problem is. By pressing the wheen back into the socket you can - with a bit of luck - make the contact better for a short period of time. In a couple of hours or days the problem returns inevitably as the dirt/dust/corrosion/whatever is still on the contact surfaces. ONLY REALLY WORKING FIX IS TO USE CONTACT CLEANER SPRAY AND COMPRESSED AIR TO CLEAN THE CONTACT SURFACES OF THE ROTARY ENCODER OR GET A NEW ROTARY ENCODER ALLTOGETHER.

[@journey4109]

It is temporary fix for 2 months.

[@omarsplaytimechannel]

I did something that I now regret.

[@grzegorzmiodek4380]

Garbage product, my first Logitech mouse that physically broke (scroll axle broke) right after warranty.

[@greyrock420]

Thank you. Worked for me. I did not have thread seal tape. Electrical tape was not sturdy enough and was tearing away. So I just put there piece of paper. It works well. But wheel rotates with more friction now. It is little worse feeling, but much better than scroll back effect. That was driving me nuts!!! One more important thing, You did not tell us that when you are removing cover, there in front there are small 2 plastic locks in the middle. Roughly same position as scroll wheel edges. It is in video in time 2:13 where it holds in the front you take it out of camera and break it open. When I opened it, one plastic lock broke. See here: drive.google.com/file/d/1BgLjTFiwKaYisJQJfGZ_igdgjLBtXvi_/view?usp=drivesdk And I think for you it happened same... Luckily it does not feel missing when assembled back together. Also some ppl claim that it help them just to use firmware update from logitech web page. I tried and I think it improved but did not fixed it fully for me. The link is here: support.logi.com/hc/en-us/articles/360024848853-Download-G603-LIGHTSPEED-Wireless-Gaming-Mouse But the piece of paper was ultimate fix for me. I was little skeptical but it really worked. Thank you.

[@greyrock420]

It got better, but I have to report that scroll back is still happening :(((

[@jear3147]

Worked for me, thanks!
