When I did this video I thought that access to the rubber contact strips was from the underside of the keyboard. Now that I know that the access is from the top, I know that I could change the contact strips in half the time. 1. Remove back casing 2. Remove keyboard cover 3. Remove control panel 4. Remove keys
Thanks for posting this video. This video plus another site with pictures on disassembly for my model were extremely helpful. I have a PX-850 and and these instructions were 100% applicable. I had issues on 3 keys. All counting from the left: Key #13 (A), Key #34 (G-flat), and Key #35 (G). The A key was the referenced loud sound issue and the G keys had a very loud buzzing sound. All 3 key issues were addressed by this procedure. Important comment on potential simplification for this procedure: the keyboard did not need to be removed for my model. Just merely removing the screws that attach it from below and above allows you to slide the whole encased keyboard as a unit. This "slide" away from the side provides enough space for pulling the keys away during removal. This significantly reduces complexity and risk (no need to disconnect any connections to circuit boards, etc.). Also, for removing the back panel and the panel with control buttons/dials, just using a piano bench or something similar on the back side allows you to set those components on so that you don't have to disconnect any of those circuit board connections either. This allowed me to have a fully functioning piano all during the disassembly process, which made it so that I could test whether the fix worked before I put it all back together. I now have a 10 year-old piano which is as good as new now. I know this video is from 5 years ago, but nice job on your first YT video. Thanks again!
I should clarify that I said at the end of the video that hopefully this will fix the problem. It did fix the problem and the piano plays like brand new again!
Hey! Great work! I also have a Casio PX piano, a PX770 and I bought it dec 2020. It’s running well but I’m noticing that the keys at the centre octaves(most played) are getting a little loose feeling, did you notice that too?
When I I start checking the keys, I admit that their is some extra movement, but no one has commented while actually playing the piano. Maybe a felt between the far end of the keys would help. Hope you find something that works for you!
When pushing the rubber contact strips downs onto the keyboard I had to use a plastic needle that my wife uses for crocheting to make the strips lay flat without damaging them.
Hi, thank you for your video. I used it to open my piano and fix the key. I am unfortunately struggling to assemble it again.I am struggling putting the digital band back into the black box (the one you take off at 4:20). Is there any trick for that? Many thanks.
Sorry it has been a long time since I looked at that piece. Try pulling up gently on the black part and then insert the digital band and then push back down. I could be thinking of the wrong piece...
Hi! I may have accidentally spilled a liquid in my PX 770 and now some of the keys are hard to press, they work and the sound comes out, but they are just harder to press now compared to the rest of the keys that are normal. Any chance you can maybe describe why it’s like that? Quite strange.
Hard to say.... I guess I would start by cleaning between the keys if you haven't already. Something thin like a baby wipe and a knife. If that doesn't help I imagine you will have to take the keys off to clean beneath.
I have this exact piano. I am stuck trying to take it apart. Any chance you can do a video about that? I can't get the control portion off...the part with all the buttons.
If I recall correctly... I removed the back panel... Then the keyboard cover slides back and off (have to play with that a little) then disconnect wires from the control board and there are a few screws across the top of keyboard and maybe one or two at either end... Hope that helps... I didn't take a video of taking apart since it was my first time
@@shannonveurink8430 halo sir, I am so glad to find this video since I had the exact problem like in this video . Two keys (G#5 and A5) in My PX‐560M suddenly producing very loud sound (127 in midi level) although It was pressed smoothly. I Brought it to Casio Authorised Service Centre in KL but they just told me that It caused by mother board problem and have to be replaced and cost me 400 USD due to warranty expired. Doesn't make sense right? So I manage to disassemble the keyboard DIY and found out that the problem come from the grey rubber band like what you have in your Video. I am having trouble to find the part. Can you inform me what the part name or maybe code number of the part, and where can I can get it as well. Any help appreciated. Thank you 🙏🙏
Hai sir, I have found the rubber contact part in Pacparts.com and ther is two kinds, 7 moduls and 4 moduls. If I only need replace 2 moduls, is that possible to just cut the 4 strips into 2 ? Thank you
So when i press down on 3 individual keys i get a snapping noise that goes away when i turn touch-response off... do you think the rubber things are causing tht too??
That's tough for me to say! Does the noise come through the speakers or is it a coming from beneath the keys you press on? Same model? Just 3 select keys, or any 3 keys pressed together?
dare walk i opened it up last night and disconnected the left speaker and it stopped mostly... there was still a slight clicky noise on the left coming from a smaller speaker i am assuming... model px-350m... Just 3 keys by themselves or pressed together -F21/G21/A21... Im gona see if it that noise runs thru a monitor... other than unplugging that left speaker internally idk what else to do
@@xeroblastx are the 3 keys grouped together... If so try lifting the rubber contact strips and clean the surface below with an alcohol swab.... Otherwise I thought parts were pretty reasonable at pacparts.com
No doubt there are better yamaha and Roland keyboards...but not under $1000. As a matter of fact, we would have to pay $2000-3000 for a yamaha or Roland with a similar feature set
@@darewalk1735 and whats is the use of under 1000 piano if it breaks constantly? I don't think is worth more than 25 bucks and only for display as a iece of furniture. I own one and regret buying.

@@darewalk1735 Hi there. I just bought a used PX750. I'm having the max volume issue on a single key (which I knew about when I bought it). My daughter has been just playing without the touch response activated. Anyway, I just wanted to clarify whether I can access the under-key strip without disassembling the whole piano. Your comment above seems to indicate that I should be able to. Is that right? Thanks, great video.
@@bradleyscott5296 yes that is right! When I disassembled whole piano I thought the contact strips were on the bottom side of the keyboard. Now that we know they are on top, it is 75% less work.

Fyi I have the same problem in my PX 560M and I already disassemble it to find the problem is from the rubber contact.
How do you put the key back in?

Soo...I got it apart. Got the keys off. They all work now, but I cannot for the life of me figure out how to get the white keys back on.
So black goes on first and the white have to hook at the front and then the back snaps down in place... I think 😊
