Hello all,

I'm new to the forum- I just picked up an old Casio PX-130 to try to get back into piano- I took lessons for several years, over 15 years ago now. The keyboard works great- except for one key that is sticking up and doesn't sit flat. Has anyone seen this issue? I've seen lots of repair videos for when the key is sinking low, and a cap needs to be replaced. Before I take the thing apart, I thought I'd see if anyone knows for sure what's happening here. The key actually plays, but obviously this makes things a little difficult. Any input will be appreciated!

I've repaired keys on a few keyboards but not Casio so can't give a definitive answer. However, it would be worth opening it up to see if it is just a simple adjustment. If you don't already have it, you can download the service manual for free here, which will should disassembly easier for you. https://www.manualslib.com/manual/2572953/Casio-Px-130.html
I hope you manage to fix it without too much trouble.

Welcome.

The diagrams are not exactly clear but it could be as simple as a displaced retaining locking clip on the key or a broken limit bracket that is part of the key itself, so do keep a watch for any loose plastic parts when you open it up.

Do keep the keys in order when you strip it down, we have had guys not doing that and with weighted keys their position is critical.

Thanks for the replies! I think I'll have a go at at least opening it up and carefully seeing what's under the hood. The manual helps, thanks for that. I'll post an update when I do.

I have a PX-560 I've had apart for a different issue. They're not terribly complex but it's a bit tedious as there are what feel like a LOT of screws.

I learned that at least on mine, if you pull up on the key, it'll snap out of its place and look a bit like what yours does in the picture and I can push down on it (more towards the back of the key) to snap it back into place. I hesitate to tell you what to do because it may not be the same thing. But you may be able to tell for sure if you at least take the cover off and have a good luck.

Good luck!

The PX-130 is very simple to rectify that issue:

on a soft surface turn the the PX-130 upside down - underneath you find a cover that goes along the entire instrument and is about 4 .. 5” wide. Remove all the screws around it and lift that cover off.
now carefully turn the instrument back the right way up - best to rest it on a cross stand so the key weights can protrude beyond the frame case. You will hear all the key hammer weights drop down. At this point all the keys should be more or less “free” or have moved into place - if any are not just hold its hammer weight and put the respective key in place.
Now comes the important part - maybe get a second person to help.
Slowly lift the instrument off the cross stand and roll it on its back again BUT you need to roll forward. You will hear all the key hammer weights falling back into place taking all the keys with them.
Now put the cover plate back into place and the keys are back in place again.

However - I suspect you may have another issue that actually caused the key to come off in the first place.
There is an “interface“ between the key and the hammer weight called “hammer cap” and these rubber caps tend to perish therefore letting the key slip off from the hammer weight.

Hi all, happy to report that I've fixed the keyboard- the service manual was very helpful in learning exactly which screws to remove, and then I went onto Youtube and found a few videos that had handy tips with similar model Casios. It was the hammer cap- when I removed the key, I found that the hammer cap had spun around and was positioned in a horizontal fashion:

So the key was resting on top of it. I just twisted the cap around to the proper vertical alignment, and the key popped back into place (you have to hold the hammer down from the back while pushing the key down- learned that after some failed attempts and then saw a video mentioning it). Thanks for everyone's help with this one- this is a great keyboard and it's back to working properly again. And now I know what to do if and when any of the caps fail down the road.

Good work.

Saved a far amount in Service Tech costs.

To use my Wife’s methodology, you now have spare cash that you can use for satisfying your GAS.

Glad to hear (and see) that you managed to fix the key issue and that the service manual was a good help. It's always great to get feedback, especially when it's a positive outcome. The motto "nothing ventured, nothing gained" comes to mind and although it doesn't always work out the way we want, we'll never know unless we make the attempt at repair.

I'm 'old school' and will try to repair anything, so long as I have a reasonable chance of doing so.
So many times, people just chuck stuff out, it drives me crazy. Waste is evil !
When I was studying marine engineering, many moons ago, we were taught to always take the line LOOK FIRST.
So often, a "fault" was easily diagnosed by just using your eyesight.
Even these days, before I do throw anything away, I cannibalise it for every last spring, nut, bolt, washer, spacer, rod, bearing or brushes.

I agree with you 100% and do exactly the same with anything that I can't fix. I have countless jars, plastic tubs etc. filled with components that I've salvaged. I even have one of those large popcorn tins filled with small plastic items of all descriptions and many times have found something I can put to good use.
It drives my wife crazy, until I remind her of the many times I've managed to fix yet another item by using something I've had stored away.
