key repair/replacement for motif

Unread post by melonhead » Sat Jan 19, 2008 12:10 am

MOTIF8.png
Hey !

I have a Motif 8 that i purchased in 2001. A few months after I bought it, it fell from a keyboard stand and the a above middle c got knocked out.. When I inserted the key back into the slot, it still plays but the action is messed up. Does anyone here know how to disassemble the the front panel of the motif 8 so that I can pop the key back in? any help is greatly appreciated. this has been a very unnerving process to say the least. thanks!

Hi melonhead,
Welcome to the Forums! Someone that has dealt with the Motif series will have to help you, all of my experience has been with much older Yamaha synths. I'm surprised that is has been functioning this long with no repair. If all of the parts are still OK, it should be a relatively easy task to put them back together once the keybed has been exposed.

Hi,

Whilst I haven't disassembled a Motif before, I've taken my EX and SY apart and they both have very similar keyboard mechanisms.

On the EX5 I had to repair a few broken keys. Believe it or not, I broke them whilst getting carried away on the finale of "Won't Get Fooled Again". 8O

On my broken keys, a very small plastic lug that holds the key in place (which also contributes to the action) was broken off. So if your key can come out easily and the action is very "floppy/spongey" and not springy then there's a good chance that the key is broken.

Anyway, if you're going to disassemble the keyboard, I'd assume the worst that the key in question is actually broken, and get a replacement from Yamaha before starting the job. They're not expensive, and the service for getting them (here in the UK) was really fast. Whilst I was at it, I actually ordered a spare of each key "type" ready for the next time!

Replacing the keys was not tricky, but time consuming as you have to work from the base inwards and remove whatever is in the way (connectors, circuit boards) until you can remove the keybed. So you need to be methodical and record where things go. And there'll be lots of screws!

Once the keybed is out, you can get to the key in question and replace it. Depending on the key, you may need to remove the keys either side of them to get them out.

I did take some pictures whilst repairing my EX5 keyboard with the intent of writing a guide, but I never got around to it. I can knock that together quickly if you wish.

Good tips there Derek! I have found that anytime I'm doing dis-assembly/repair that it is a good idea to keep a digital camera handy and take pictures often to document where everything goes. It can save you a lot of grief when you are putting it back together.

Digital cameras are great for that!

I ran into trouble when doing that SY77 display repair, and it was referring back to the pictures that I realised the mistake I had made!

thanks for the advice! unfortunately, i'm still unable to lift the front panel to expose the keybed. I taken out every screw ! And now I have to be able to lift the front panel as the power input and power button have fallen through. I'm in a bit of a pickle. What's worse is that I have my senior recital in a month! ahh! Is there a yamaha technician I can contact or a link that can point me in the right direction? thanks ! :)

Not sure where you are located, but you should be able to go to the Yamaha website for the country/region that you are in and locate an authorized Yamaha service center. Start here at Yamaha Global: http://www.global.yamaha.com/ and then go to the links for your area, then there should be a resource/links for authorized service.

Have you fixed your key yet? My son also has a broken key on his motif 6. If you know how to do it please let me know. Thanks! Nilo

Hi nilo,
Welcome to the Forums! If your handy with mechanical things and electronics repair, I'm told it is not that difficult, just lots of dis-assembly (preferably documented with a camera to aid in re-assembly), replacing the part, then re-assemble. There is also the option of an authorized repair center, I've opened up several of my keyboards and performed minor service but would likely use a service center for a broken key.

If people want, I'll hunt out the pictures for when I did the key replacement on my EX5 and write up a guide.

Broken keys

Unread post by Kingell » Mon Mar 10, 2008 11:58 am

I have a PSR9000 and unfortunately one of the roadies damaged several keys at the upper end. It was a task to replace. I had to remove the base then all the boards. Each of the keys is marked with its note name. It was quite easy to do once stripped but what a task disassembling and reassembling. :roll: If your aftertouch operates like mine you could have some dirt on the strips below the key. Try a strong vacuum cleaner - it might save you a lot of trouble. Good idea to take photos. I'm a trained electronics engineer and it helps to remember where plugs and screws go.
Good luck. :lol:

i would really appreciate that, if you put up the pics up somewhere.

i bought an sy 77 not too long ago, and the transport seems to have done some damage to a key and i want to fix that.
my piano teacher said he often experiences loose keys on his dx7, so i'm hoping it#s not broken but only loose.

i won#t see him in a while now, would ask HIM if i could

i have never done that before, so i could need something to get a bit of an idea what this task could look like. i am a bit afraid of being unable to close it properly again after having opened it.



very good forum you got here

It's not too difficult to do it yourself. First make sure you can buy the replacement keys - and make sure you ask for the proper key - letter C and F - and B and E - are not the same for example - although they look so. :roll:
You can expect to remove many screws from the base.
Get some little tins to keep the separate screws in and stick a label on to say where they came from.
Now put a soft cloth on a strong table and put the keyboard upside down on it. As you remove and unplug things write down what and where.
Taking a digital photo will help as you go along.
Also see my posting above.
Good luck.

thank you, i read that.
these tips sound quite reasonable. guess many learn that by not doing it n the first place.

i was just looking for pictures.. smth that shows me what my sy looks like inside. searching that, i found derek's guide on display repair... took the fear from me, i believe.

nad, ahm, klingel: have you had experience with BROKEN keys? seems like nobody in this thread, i believe even the whole sy forum considers the possibility of keys just being loosened... is it really more likely they are broken?
