- DX7II and DX7s, contact failure of common tact push button switches is restored by pouring contact spray(not a cleaner spray) inside the switches.
The same type of switches is also used in Roland D-50,D-10,KORG M1 etc.
発売から30年以上たったDX7Ⅱ,DX7Sでは、よくあるタクトスイッチの接触不良ですが、スイッチ内部に接点復活剤を流し込むことで復活させています。
他にYAMAHA V50,SY77,Roland D-50,D-10,KORG M1等でも同じタイプのスイッチが使われています。 - Hudba
Holy moly I just did this to my D-10, works perfect! I didn't use the tube, just spray enough and work the switches 20 times. So happy :D
Thank you for this video! I have a Roland Sound Canvas SC55 module from the early '90s that had some very inconsistent buttons. I tried using a tiny bit of Deoxit D5 contact cleaner and pressing the button with my finger repeatedly and it seemed to help but not much. After watching this video I saw that probably a lot more contact cleaner was needed to really flush it out and a harder object to press the button would likely help to give it enough pressure to clean the contact inside. There isn't enough room on the PCB to do the pen trick, so I just used a paper towel to absorb the overflow and doused each tact switch with Deoxit and then pressed it several dozen times with the plastic handle of a tiny screwdriver. This made a HUGE difference! The buttons are now working like new! When I got this unit the outside button caps were damaged and I fixed them, but when they weren't reliable I thought for sure I would have to replace these tact switches too. I'm so relieved that a good cleaning is all that was needed.
Thank you again!
Hello & thanks so much for making this video! I just fixed all the buttons on my Roland Rhodes MK-80 - cleaning went very fast and all the buttons are working like new again. This is the best method for cleaning tactile switches I've found on the web. cheers!
Hello.
My mk-60 also fixed the switches.
at first I was going to sink the pcb in liquid pool to fix the switch, but that was not realistic.
Thank you!
Great video. Thank you also for the subtitles!
These switches are in so many musical and other devices.
Thanks! I used this method to fix the tactile switch on my 5 year old electric toothbrush. Works great now!
I didn't have contact cleaner but just used methylated spirits aka denatured alcohol.
どうもありがとうございました！ Thank you!! Using this method and "inox mx3" as the contact spray, I have repaired not only my DX7ii FD , but also my Korg EX-800 and my Korg DDD-1.
Has the repair held up, or did the switches start giving you trouble again? I’m about to try this on my DX7II, and I’ll use the inox if it worked for you.
@@bricago2302 yep still working great for me 2 years later !
Thanks for sharing, this is going to save me a lot of soldering!
ありがとうございます！！
すごいおたすかりました！！
World should know this guy saved me around £79 thanks mate for this life saving video
It's even cheaper if you buy new switches from sites that sell electronic components. These switches are regular tactile switches they cost like 2 cent a piece. I've used them in my Juno 106 and they work like a charm. Desolder the old ones and install the new ones. The entire fix should cost like 1 euro. Don't get these components from people who label them as "Yamaha switches" bla bla. You'll get scammed by them by paying like 5 euro for a component that costs 2 euro. Fucking sick dude if you ask me.
Thank you sir, just did this with the switches of my dx7 mk1 and it worked like a charm.
Greetings from the Netherlands.
Thank's!!! I don't have this contact cleaner but I tried using isopropyl alcohol instead, just like you did. And it works great! Domo arigatou gazaimashita!
Thank you so much, I was able to repair a balance of 150 $ in 15minutes! :D (I was going to trow it away and buy an other one)
THANK YOU MAN!
I fixed the shift button of my MPC2000 and it is ready to make music now. I really appreciate it!
excellent video. I have a number of SY77 in need of just this
Thanks for this demonstration!
Brilliant! Thank you! My JD800 is much less frustrating to use now :)
I tried this with my DX7IIFD, and it kind of worked. There were 13 intermittent and one dead switch. The cleaning restored 7 of them and brought the dead one up to intermittent. Time-wise, it would take about the same time to replace them. Rather than try again (soaking them longer, I suppose), and hoping it works, I’m just going to replace them.
Good work, #1 on my DX7 ll has this problem.
Great! it works for me. thank you
thanks it's worked for me.i use the isopropyl alcohol.during this pandemic is not easy to order the parts.i just follow your guide.now my line6 hd500 working perfectly.
Thank you verry much. No Ive repaird my Roland JX305 Arp- Button 😀 with contactspray.
Oh My God This is right on time...Gonna look up contact spray prices right Nizzle!
Thank you for saving my mouse! :)
Thank you!!!!
VERY GOOD!!!
Can this type of spray be used for sliders too?
Will this fix tactile button bouncing
Could work in an Access Virus TI 61?
Thanks 👍🔝
sorry for asking i dont undertstand: is contact spray like WD 40, and contact cleaner like isopropyl alcohol..or? dx II here i have 1 dead and 4 hard to push
Good video but i do notice you use to much contact cleaner fluid, a small amount will do.
Fixing up an AKAI MPC1000128XL right now... those sad, sad UI buttons (not the pads) were just dying.
This is awesome. Thanks for sharing your knowledge. Does anyone know if DeOxit is a contact spray or a cleaner spray?
Definitely CAIG D5S - 6 DeoxIT is a contact spray.
@@jskawa Quick reply! Thanks so much. Really really appreciate this video by the way. I'm really pissed at Yamaha for making the DX7ii (and S) more complicated to take apart than the original!!
@@MIDERA It's a pain in the ass to open the DX7II FD. I wish it was more easier like a Juno 106. But this fix isn't the best, these tactile switches are dirt cheap they cost like 2 cent a piece. All you have to do is buy them and install them. I've done this on my Juno 106 and it works like a charm. The fix should cost less than a dollar.
@@padmad3k63 Thanks for the tip. Can you give a few specific examples of where to buy the switches for 2 cents each? And how to determine the correct type/size of switch?
I had a button switch that would only turn on when pressed hard (past the point of the click).
I didn't expect anything, but I used a toothpick to drop a couple drops of 70% isopropyl alcohol on the inside of the button and it instantly worked perfectly again.
Is it still working? If I am not wrong, alcohol has a low boiling point, this fix should not last very long.
@@Brian16537 You are right, I tried it again now and it is back to how it was.
I guess I'll need to get some contact spray.
hi i need help what is best tact switch cleaner i have korg pa4x
my korg switch / half of it doesn't work And some of them have to press hard 10 time to work
this has happened because of my room temperature and moisture and my korg is like new used just home 2 years old any help
It is not a cleaner. Use a contact spray like WD-40.
@@jskawa many many thanks man i will try
@@itkurdpro Bro, don't use WD40 it can be very messy. Better fix, get new switches they're very very cheap like 2 cents. Just desolder the old ones and install the new ones. It's even cheaper and faster. IMHO the proper way to fix this since a new switch is always better than an old one.
@@padmad3k63 thank you very match man the problem i don t now where to bay same tact switch for my korg pa4x
@@itkurdpro These should work:
www.ebay.com/c/14010027666?iid=273790653226
100 switches for 2USD lol others sell like 10 switches for 1USD. Too expensive. So many people will rip you off when it comes to these parts bro. It's a shame.
Get those from that eBay link they will work.
can i use wd 40 instead?
I don't really think so. You better you some contactol, or at least alcohol to just clean it.
I will try after i watch this video..tq for sharing...😁👍👍
Hi! can i use WD-40?
If this is still useful 4 months later, you cannot use WD-40
@@christianm4947 Just desolder the switches and install new ones, it's waaaay cheaper and easier to do. These tactile switches cost like 2 cent a piece.
This costs too much money and time. It's just a simple tactile switch which costs like 2 cents. Just buy it, desolder the old one and solder in the new one. I've replaced all the tactile switches on my Juno 106, quick and easy.
What the fuck wrong with you. Desolder and solder it's not QUICKER and EASIER then this method! You need skills to do proper desoldering and soldering
@@Rotaks Soldering trough hole is easy especially on these old boards. The chance ruining this button with the method displayed in the video is pretty huge. These buttons cost nothing. I've placed them all on my Juno 106 and my DX7II. Saying soldering is hard is a stupid statement. Even a 8 year old kid can solder.
@@padmad3k63 "Saying soldering is hard is a stupid statement. Even a 8 year old kid can solder." Ok. Now, GET THE FUCK OUT you morron.

that push switch is a always noise click click click..
not good...
better rather use a quiet silent push switch
can I use penetrating oil as an alternative? I dont have a contact cleaner? :(
I used denatured alcohol aka methylated spirits. I think penetrating oil is a lubricant, whereas you want something that's a solvent that cleans and evaporates away after.
Temporary solution
