Appears to be the same as Yamaha V-50 also. Note, the plastic projections that supports the spring towards the front of the key were breaking on my V-50. Only on the white keys. I think they become brittle over time. I had to machine a 1/16 hole and epoxy in 1 1/16 metal dowel on the white keys. Worked like a charm.
Do you know, if these SY77 keys are compatible with the YS200 FM keyboards? I have one broken black key in my YS200 from 1988 that needs replacing. Yamaha has no parts anymore after just 30+ years. ;)
Yeah, to piggy-back off of Rik's comment, on the DX11 there's a rubber 'stopper' that MUST be removed before you can remove/replace keys. Fortunately, it just slides right out.
A couple of notes: 1- you can’t work on black keys if there are white keys in front, to replace a black C# I had to remove both the white C & D keys. 2- on the SY35 there’s a soft rubber strip that hooks into the back of all the keys, I had to gently move that out of the way in order to extract & insert the keys.
how do you get access to the keybed? been pulling different bit off my SY55 for a week now and this is the most useful video i’ve found so far ! cheers
