If any key on your keyboard does not work or does not respond correctly to your fingertips, you should do the following:
1) Remove knobs and sliders, open the keyboard, remove plastic buttons, and gently remove rubber strips on electric board;
2) With a pencil gently colors the contacts of the sensors located beneath the rubber strips;
3) Replace the rubber strips on the contacts, reset the plastic buttons, close the keyboard and retrieve knobs and faders;
4) Enjoy it and please like this video! ;)

I tried to fix dead keys for two days without success...I resorted to onlone help...I found a very good advise.I used the pencil and all problems were solved in few minutes.Thanks a lot

You're a sinner perhaps🙄😁😂

[@renacarter9541]

After searching the internet for a couple days trying to fix dead keys. Cleaning didn’t work and I noticed the missing connection. I just happened to come across this video. Thinking to myself, this is a load of crap since you never showed the keys not working in the beginning. Decided to give it a try anyways, and it freaking worked. Thanks 😃

[@dnyaneshwarmhaisane3605]

This technique is works 75%, I just tried it I want to give one my personal experience if ure key is not working after the pencil use then use erase o same key it will 100% works. Thanku🙂

Just throwing my cents here: The pencil fix can work fine, but if a key is dead, always clean the contact first with circuit-friendly cleaning fluid, then reassemble and give it a try. Sometimes it's a thin layer of dirt what's causing the faulty connection. Adding a coat of pencil graphite can fix the problem temporarily, but that thin coat will wear out eventually.

[@lamijerald2364]

Hi......Which Fluid can that be please coz some times using a pencil is short lived. and I wanted a parmanent solution or atleast for a long time. thanks you in advance

[@SnypieExe]

​@@lamijerald2364Isopropyl alcohol is good for cleaning any circuit without damaging anything

[@slayridah]

​@lamijerald2364 I'm gonna try buying a new contact board, which is what the rubber pads press down into. Not sure if there is a more permanent solution other than that but I'm sure you could use some other material thats more longer lasting but i just have no idea. Maybe $50 buy a new contact board compared to $2500 for a new keyboard in my case.

[@slayridah]

​@@lamijerald2364also the curcuit friendly fluid he's talking about is simply called electronics cleaner. Wd 40 makes some that us meant to be used on sensitive computer parts like mother boards and contact boards to clean them.

Thanks for saving my Yamaha Keyboard. I tried taking it apart cleaning it everything it just kept getting worse. I was thinking it was going to the garbage can but then I found this video tried it and it fixed all of my dead keys. Plays 100% now thank you so much again. Also I dropped a cup of coffee on my keyboard that's what screwed it up and it still work

[@Alice-fs5sq]

Какое полное название у вашей модели?

I've done so many times for decades it's not permanent but sometime last for about a year. Worth some tries as it pose no harm..

[@mynameisdanman]

I was so hesitant to try this... but after hours of cleaning and tinkering with the sensors I finally tried this AND IT WORKED!!!! THANK YOU! I did this on my Korg Kross 88-key Workstation to fix two keys that were stuck at full volume. Thank you again.

[@jaimemontero6712]

Seems like a common kross 88 issue. Gonna do the same to mine. How's yours holding up?

[@mynameisdanman]

@@jaimemontero6712 after a year or so one of the keys started to mess up again, but all in all the fix has really held!

[@johncraven4539]

I would recommend simply rubbing the contacts with a cotton swab moistened with distilled water to minimize residue (I used the water condensed under the lid of an electric kettle). This fixed 2 non-working keys, and I did the whole keyboard to prevent similar occurrences in the future.

[@YTJ3]

Thank you so much Man. You saved my piano of 8 years.

[@diegovalenzuela4608]

Thank you very much! It worked on my Korg SP-170DX which was dead for 2 years, what I did was scrape a lot of the lead off the pencil and emboss the contacts with it

[@redteamgarage299]

I fixed the same issue with my CTK 3000. Here is the quick fix, you need: 1. Interest in technology (to open the casio) 2. Simple Pensil Eraser. I rubbed the same surface area with rubber and the rubber sucked the entire black dust and now it is working just like before 💯

[@kawaii2811]

Some more tips. So on my keyboard, 3 keys went dead. Cleaning the landing pads and swapping the rubber membrane did not cure the problem. Looking at the circuit board, I noted that keys are wired in groups. Although the three keys were not next to each other, they were in fact part of a group. So I traced the fault to a break in the PCB track. I fixed this with a bit of soldering and the dead keys are now alive! However, all three now play louder than any others. This cannot be due to their membranes, as it is not common to all three keys. So I have more work to do!

[@bol7]

Hey, you gave me a big hint! In mu case contacts under the keys were totally fine. I found a tiny corrosion on pcb board connector, it made 3 random keys dead with my casio. Now it's fully working again. Thanks mate!

[@jamesgraff2705]

I wanted to give an update that it has been two months of heavy playing and my keyboard is still working perfectly after using the Pencil Trick. After spilling some coffee I had a dead key and the more I tried to clean it more the problem spread until I had about 10 dead keys

[@patrickh2053]

Thank you sooo much! I had an old Casio 671 keyboard, not in use fo rmany years. The keys were working fine, but the buttons, that you need to use to select t he sounds or rhythms were not reacting, when pushing them. Also the on/off button did not work most of the time. After cleaning the "contacts" with alcohol and additionally applying some pencil on them it works now like it is a new keyboard!!! Can't thank you enough :) Now my kids can use my old keyboard to practise music

[@malabarspyder]

I did this as well. The problem is its easy to short out the contacts with graphite "haze" on the non-contact portions. My fix was to go over it after with a Qi-tip and a lighted magnifier to find the shorts. Worked great! NOW my issue is that one Bb ALSO plays the # above it every time! GRRRRR

[@ricochet5211]

This really worked!!! At first it didn’t but after wiping the excess pencil off the sensor it works

[@666pinkster]

I've seen a few videos like this, but it works better if you clean the contacts on the PCB board, and then apply graphite to the carbon contact in the the rubber strip

[@BenLJackson]

I had that problem. Mine was because the board was corroded from soda. Clean between the solder traces with alcohol and a cotton swab, then scratch the junk out from between connecting solder points with a file or your nail. I even washed it in the sink with dish soap and dried it before putting it back in.
