My Yamaha PSR E 373 piano keys are internally like the ones on yours. The thing is that 2 black keys are broken and here is my question: Is there a way to glue them (they are broken on their articulations (like hinges)) or do I need to replace the whole 7 black keys?
I pulled off 3 of the rubber strips to fix this liquid spill. The rubber strips were all the exact same size and the contact pads were all the same size. Different keyboard model might be different though.
Right at this moment I'm cleaning a Casio VZ-1 for some issues. Came actoss your question while wondering with what detergent to clean the rubber. The ones away from you, seem to be a bit longer. Perhaps two or three milimeters.
You’ll need to find someone in your area that can do board level component testing. Search for “micro-soldering” or “IC replacement” or “SMD replacement” or “logic board repair” It Could be a bad capacitor on the logic board, assuming you’ve already tried a new external power supply and cord at this point. Most guys that do board level testing and troubleshooting are expensive ($100+/hr). You might find that it is not cost effective to repair, depending on the current value of the keyboard model you are trying to fix.
Hard to know. If it lights up when plugged in, it could be a few different issues. If it does not light up or power turns on, then it may have a damaged A/C jack. This is where the power supply plugs into the keyboard. That will sometimes be damaged if power cord is kicked or pulled out improperly.
I've done this method. And it works for an hour but again it became dead again. Key Problem was sometime dead sometimes ok, some time sound comes with louded and sustain. What should I do now?
If you are 100% sure that the contacts shown in my video are clean (be sure to look very close) you may have a different issue or a logic board problem. I would suggest double checking the contacts on the rubber strip under the key assemblies themselves to be sure there isn't residue on that end causing the intermittent contact issue. Remember that there are contacts on the green area of the circuit board as well as the little round contacts on the underside of the gray rubber strip. Maybe even try moving the problem keys to a different position on the keyboard to see if the problem moves to the different key position that you moved the key assembly. If the problem moves to a different area of the keyboard as you have moved the keys too, that will tell you that the problem is with that specific key or group of keys. Then you can could try to determine if it's a physical problem with a specific key group. The fact that it works temporarily and immediately after cleaning but fails again after a bit of time, would suggest to me that the contact points may still have a bit of residue on them somewhere. Be sure to use plenty of alcohol when cleaning both the little round contacts on the underside of the gray strip as well as the contact points on the green areas of the circuit board too.

What liquid is best for the cleaning of the panel
Please, I want to know the rubber contact is one point short or both of them are long ?

My ew300 some of the keys are not working when I first turn it on
Very nice information .
Do you know how to fix current leakage

I have a key board psr320 at any time you on the key board it will not make any sound please sir how can I repeir it sir

@@chadmccollister TQ. For suggesting me. Let me do this method for once more. If this problem occur I would give to pro. Maker
But I didn't use any liquid such as alcohol. I cleaned by brass only.
Facing same issue with my psr e363
You jump what i want to see, how to open the keyboard
Just a suggestion: Mount your camera on a stationery surface instead of moving it around by hand. You're moving it too fast. I couldn't watch.
We didn't even see if the keys weren't working at first
