A comprehensive, detailed disassembly, repair and rebuild of a Suzuki HG-425e mini grande digital piano to fix keys that stick for free with minimal tools and no replacement parts.
Required tools:
Philips screwdriver
Triangular screwdriver or bit or something else that will fit
Fine-grained sandpaper or file
I used some pliers and a mallet, but they are not required
Note: this process took me a long time. I lost count, but it was quite a while. Hopefully, this video will help you to do it faster with no guesswork as to what the next step is.
