Hello PW!

I'm looking for some help and advice on how to repair a Roland F-110 with a broken key. The warranty is long gone and the place it was bought at are asking a very high fee for a simple repair. There are also some logistical problems in moving the piano to the shop. It's my sister's DP and she asked me to help her repair it, so I figured I'd just order the needed part(s) from Roland directly. I'm not experienced in DP repair, and I've found nothing on the internet about the F-110, no pictures of the internals, no service manual, nothing. What am I getting into here? I really don't want to damage the piano trying to repair it, especially as it's not my own. I've found some videos of people replacing broken keys on Roland keyboards and it seems easy enough. Problem is, this DP doesn't seem as easy to open up, there are more screws and more stuff inside, like the speaker system.

This is the problem, G# just sits there sunken down into the keybed. It works to play on, but has a very spongy response. I strongly suspect the plastic hammer is cracked like in the videos I've found, but probably hasn't fallen off completely.

Does anyone know how to open it up safely? I don't want random parts falling out... I'm looking for tips on what screws need to come out, how to handle the piano without damaging it, and so on. I took what photos I could and color-coded the different sets of screws to make it easier to identify them. I'm not sure they belong together the way I coded them, but it looks like it. I'm assuming the stand will have to come off, but that shouldn't be too hard.

Bottom of the Roland F-110 (click for higher resolution).
Red - Probably securing the speakers to the board?
Purple - Headphones hook I think, looks like a hex in there?
Orange, Green, Blue - Not sure, probably holding the box together?

So, orange, green and blue seem likely.

Back panel of the Roland F-110 (click for higher resolution).
Pink - Not sure, holding some components inside?
Yellow, teal - Circuit boards?

Not sure if anything needs to come off the back, but included it anyway. I don't know what the sides of the unit look like without the stand, and didn't have time to take it apart during my recon visit. More screws?

I found this isometric perspective of the F-110 in the manual if that helps in any way.

Grateful for any help you experts on here have to offer! This problem is causing my sister to not play much anymore because the broken key bothers her so. Pianos must be played! smile

Thank you!

I don't know about he F110, but you can have a look at some pictures I did for taking apart an FP3 here.

I would guess the lower green and orange screws in your picture are holding the keyboard assembly to the case - don't remove.

The yellow screws will be securing the sockets to the casing - don't remove.

I would start by removing the blue ones, then the pink and teal ones on the back if the top cover isn't moving.

Good luck!

I don't know about the F-110 either, but some generic advice might help.
I would first look at all the screws around the edges (the orange and probably the blue ones). It may be safer to just undo them a few turns so that the screws stick up a quarter-inch or so.
Then you can see if there is a gap opening up in the case. If not, loosen a few more. But I would leave the center row of green ones alone. It's unlikely that they hold the case together.
When you actually get to take out the screws, make a note of which type goes where (unless they're all the same). It's not as difficult as it looks to open most DPs and keyboards and you seem to be very well organized and careful.

Thank you lolatu and baladin! It's nice to at least get some pointers smile

My instinct tells me the screws on the back panel aren't involved in holding the case together, the reason being they're not symmetrically placed along the back. Surely any designer would have a sense of symmetry, for stability and aesthetics. Like the green ones on the pictured FP7. I might be wrong though, we'll see!

I believe I'll start by removing the stand, then loosening the blue screws on the sides, then the top orange ones. Good idea about unscrewing them halfway and jiggling the case, that'll make me a little braver! You're probably right about the lower orange and green screws holding down the key assembly, but probably also the front panel. Hopefully that won't have to come off.

I'll update when I've given it a go, will try to get some pictures on here in case anyone else should need them. Won't be for a few days though, open to other suggestions in the meantime! Thanks guys.
