Another thing Markus.... Tried lots of other sized bands and had the same experience as you....put the right ones in and it worked straight away!

Hi Markus!...sorry just looked up your site again as I had issues with my disk drive on w7 again. Saw you had replied to my comment. Hope I'm not too late.. lol. Found the belt drive for the W7 at Syntaur Parts in US about $16 US. but beware ….there are 2 different types of A drives used for W7's so need to watch out for that. these guys are great to deal with and are really passionate about their stuff. Found that the belts had perished again so will have to get some new ones. Once again your info was invaluable. Thanks heaps for the time taken! Pete

Great1 I have the W5 and there are issues. One main is the buttons you just replaced. Another is the display that has to be called blank, so dim. The jog wheel is kaputt with a loose cord I guess and the increase button not work -only the decrease button. It's a cool machine. The age is unbelievable 26 years and a pretty woman still. Thanks Mark. Goaan replace the battery at least.

Markus what a great video! I have two of these babies at home and what a wonderful help you've been . Both have disk reading problems but ended ordering belts rather than a new disk drive which I was about to do! Such a valuable wealth of knowledge! Really, really appreciated! Pete

So exciting, new synthesizer repair video!

Excellent video, as always. I owned 3 of these over the years, and on 2 of them i replaced every single tact switch. Big-ish job, but worth the effort. The switch & disk drive problems were a common issue with the W series, i seem to recall. :)

I'd call this a win, definitely; the problems that weren't solved in the video have solutions that you know about, so you can deal with them as you wish. Your method of finding/sorting out the key volume problem is a testament to why a person, after testing a newly-ordered TR-505 with a few 'dead pads' should probably check the volume levels of every sound, before opening the unit, and lightly abrading the carbon contacts. Not that I ever did that. I love this channel.

Thanks for this. A similar set of issues affect my SY77. I tried a new band in the floppy drive but something else wasn't working... Also the screen - same deal, but it works still!

Nice. Gives me the incentive/courage to pull apart my Korg M1 pawn shop find to replace a bunch of switches that I've already acquired. Nice tip on the battery replacement as well. I did a SysEx dump of the M1 when I bought it just in case the battery dies before it gets replaced.

Thank you very much Markus for great video-lesson.

Really cool repair video. Thanks for this one :)

If you can get hold of an NEC FD1241H direct floppy drive along with the 26 pin to 34 adaptor on ebay, this combination will swap out directlt with these dodgy Matsushita EME-213-YN belt driven drive. I have done this with a PSR-620 and SY85

you can order EL strips on ebay. I've found one that was wide enough but double the length, so I'm folding it in half. they're fairly cheap

Very nice video!

I got some of my switches out of old pc mice.they work perfect.

Awesome video... I have the Yamaha QS-300 and by the way they look very similar... but about 10 years ago I had the same problem with the display and I replaced the whole module with a L.E.D backlit display, it wasn't easy as I had to follow the connections of both data sheets to match the pins, but it's been working ever since. And it's a lot more pretty to look at with the white font and blue backlit..

Great video 😊

At least the buttons respond now - shame about the floppy. - good instructional video as usual - thanks.

I really enjoyed the look inside another vintage instrument. I think you may be dealing with a power supply problem going to the disk drives. By the way, 720K is the format Amigas used. Oh, I've found a solution for your backlighting problem.

Excelente video maestro saludos desde México una pregunta de cuantos pines son los interruptores táctiles que reemplazo?

Aw, too bad about the disk drive! Great video Markus! Btw, a few years back I saw that one could buy luminescence strips that one could cut. I can't remember where I saw them but that could probably work for your display!

You can find cuttable el panels on eBay, you can cut them to your required size and fix the backlight problem.

Hi Marcus. You're videos are inspirational. I succesfully changed my sy85 floppy drive a few years ago. The guys at Yamahaforums have quite a bit of help, though ive got an audio interference problem on the sy85 I cannot fathom. I wondered if you had any advice? There's a very high pitched whine on audio out and on headphones. It glitches, sort of like a dial up modem sound when bank change button is pressed e.g. song to performance to voice. Last time I opened it up I had no idea what I was doing. Feeling braver and inspired now, but would welcome any pointers as to what possible fault I'm looking for. Thanks in anticipation.

thaks

Very very very very good

Same problems with my SY-77, backlight and floppy drive are dead but all buttons working. All data in and out is done faster over sysex anyway. The only difference in the 77 is that I had to unsolder the old and solder in a new battery followed by a factory reset.

Have just came into ownership of one of these, sound great but has the exact same issues as yours, i think its all about the patience in fixing the Tactile switches let alone getting the right ones on order. The floppy is a right off but curious if the atari or amiga one would fit. Backlight has gone too, ive had loads of synths like that, the qs300 is similar. Thanks the video though.

Rather like the belts, replacement electroluminescent backlights seem to be seriously overpriced. Instead, you can buy sheets of EL foil for a much more reasonable price and cut them to size. I did this with my Emulator II and have been meaning to do the same with my Yamaha QX1.

Under the heading "nothing to lose" if the belt on the floppy is in fact slipping. An old trick for belt driven tape players was to wipe the belt with brake fluid. Then wipe it clean with alcohol. The brake fluid would cause the natural rubber in the belt to swell. This is quick fix that would get you going temporary. After a few months the belt will shrink back up again.

I have a Yamaha EX7 which also had a lot of dodgy buttons replaced some of them but other have failed since contact cleaner does not work for long. Those old keyboards were very heavy, but were built a lot stronger than the £1500 to £2000 keyboards nowadays and I assume would stand up to gigging a lot better :-)

Hi @markusfuller Should I be awared to get electric shock while I´m changing the battery ? -and what is that for a kind of cable you have on your right hand ? - is that something antishock prevention ???

Hi Marcus you can get an adapter for the disk drive cable which converts to a standard floppy drive connection I did this with my sy85 using a Sony floppy drive. The video on our channel ‘take the fear out the gear’ shows this mod. Cheers Simon

old pc mice have perfect buttons for the w7

The disk drives are brutal.

Did you check the voltages and signal lines on the floppy data cable ?

Come on, Matsushita Electric was foremost about quality and reliability, as opposed to Sony being about maximum profits. Sony consumer products tended to die sooner than anything branded Technics, National, or Panasonic. In broadcast market though, both Sony and Panasonic are very respected, as well as JVC. Anyway, I had replaced the belt drive in my SY99 and the backlight display in the SY77. It took me five times to nearly completely disassemble and reassemble the SY77 to make the LCD backlight work properly. I broke the display in the process. I got the new LCD assembly, and it finally worked. I find it very difficult to properly settle the LCD backlight strip. And by the way, I would never install the "cool blue" LCD atrocity. It brings the look and feel of the Yamaha otherwise flagship synth to the level of MX-series.

Hi Mark Doing the same with my W5. Have put in a USB disk drive emulator and have ordered new screen and tactile buttons. Quick question - what soldering iron and solder did you use or recommend. CHeers

It does sound good. I wonder if the Motif has some of the identical waves in it

Just acquired one of these, couple of stuck buttons and the data entry wheel seems flaky.

good morning I have a yamaha W5 and it sounds like when I play it a bit loud the keyboard with intermitencia.y uncover it and change the battery and I did not see anything loose. What will it be?

Would you help me with advice. One key is stuck and does not move. What do I have to do to peel it off. thanks.

Hi, I have a question, my yamaha motif 6 when I turn it on, it works when I change sounds at 2 or 3 minutes, it does not have audio it stuck I changes the internal battery, I programmed with os , I reset Does not do anything any idea thanks

Hi Markus, you have great content and vast knowledge. At 15:00 what were those two tools you were using please? And what were you doing exactly it looks like you well loosening and pulling the old switches from the board but the board is reversed so...I'm looking to do the same thing on my keyboard.

Great video - the frustration with the floppy drive mirrors my experience with my Roland XP-50. Given all the suggestions for fixing the screen light and floppy will you do a follow up?

I have the Yamaha V50 with the same floppy problem. Maybe it's screwdriver time for me as well :D

Hello Markus Maybe you could solve your problem of rubber belt by cutting it diagonally for shortening a little bit and use a special instant glue used to glue O rings. I found O ring of all diameters sold by meter and this special glue in a workshop who sales pieces and accessories for jacks, it's very cheap ! rubber for O ring is very resistant and could easily replace a belt...

Mark, I have a question for you. When you took the buttons off did it require soldering? I have a dead key on my Korg DSS-1 and I need to replace it. Thanks for the awesome videos. May I request a video on changing the floppy drive to the USB drive. I'd really appreciate that. Thanks for making the wonderful videos. I always enjoy them. Take care and have a wonderful week. Sam from machiwoomiapoo

Do you know how to get the Jog-wheel to work? 99 of 100 it doesn't work. One of the increase - Decrease doesn't work either for scrolling for sounds. It's a Yamaha W5

Hi Markus, I need to replace couple of tact switches on my mpc, do they come with different parameters (except size) ? as the original ones are more than 300 times more expensive, and i would have to pay for shipping, but nearby they sell them for very cheap and they look exactly as those that I need also, is there way you can connect them wrong, or it really doesnt matter how you connect them?

Could you Araldite an additional tension wheel on to the chassis to take up the slack of the loose belt?

Good morning, I can update a w5 to w7 by changing the card, there is a way to reset the W5 to factory settings

what do you charge for repairs on the W7?

Would a contact cleaner fix the button problem without actually replacing it? If a button still "clicks" it normally means the little metal plate inside it is still Ok, innit?

Someone gave me a W5 (monster 76 keys!) for free. The Curve setting helped a lot. Thanks!🎹

Two wrist-watches, digital + analog?? :-) Nice video, as always!

How's To cek ic Dead yamaha keybroad w7 ya

"I must read more of these things" - hilarious

Yes, I have heard that the floppy drives on these machines are MatsuSHITa too! Lol!! :O

Can you help me? I have YAMAHA MOTIF XS6, sometimes my power-switch button is not working and i can't to launch my synthesizer. Sorry for my language, im not strong in english.

Did this come out before or after the QS300? I used to have one and it looks very very similar. Still have the factory disks somewhere. Lol.

put the band round the pin next to the motor spindle to take up the slack!!!! :)

I've had success using contact cleaner on those switches. ref: 13:12 Thumbs up.

Hi Markus. What size are the buttons needed to replace the faulty ones? I'd like to buy the correct buttons before taking my W7 apart. Also, I've fitted a new belt to the drive, but still the drive doesn't work. Could a good clean sort out the problem? Thanks in advance.

I have a w5 and of all the buttons the voice edit button and enter button don't work

Hi Markus, I had the same problem in my Korg X3R, same brand of floppy I believe. I tried the elastic band trick and got the same problem you encountered. I found a bespoke replacement belt online and it worked fine. I think these drives are sensitive and maybe a rubber band just has too much friction or something ... But you're right these belts are expensive. As far as the backlight, I was excited when you talked about replacing the CCL with an LED array: even though it didn't work out in this case, I would love to see how it could be done in general, cos I don't have the faintest idea where to start with a project like that ... Any ideas?

I juat wanna ask...whats the name of that light for lcd of yamaha w7 and where can i buy?thanks

I have a W5, with many songs stored on floppy disks. If I am not able to repair the disk player, is there any way to retrieve the data from the disks?

I don't know how much you care to get the floppy working, but I found a pinout of the W7 without to much fuss to wire in a standard drive.

Hi I like your videos I have a question my yamaha psr 540 works well but when I connect it to the mixer or amp makes noise or buzzing ground I check the jack is fine thanks

Hey Marcus, I know I could chuck anything on it but do you know a place to source a Yammmy CS1x knob set? Got a few missing.

Блин! У меня такой же синтезатор и точно такие же проблемы. А как называется пластинка за экраном, которую нужно менять чтобы заработала подсветка? На алиэкспресс не найти такую?

do you know how to set the octave on those, mine got changed and cant change it back. dont have a manual and the ones on line are crap.

perhaps roughen the traction surface with a emery board ? I remember in the 1980s dismantling those early VHS players that were full of rubber bands and gently heating the band with paint stripping heat gun which would shink the band ?

You're doing the impossible... For miracles you need some time to get organized ;)

Is one or both of the touch screen synths in the room-o-synths a Tyros?

How to fix yamaha p45, automatically play demo songs and i can't remove it even pressin the grand piano button, when I turned off the piano I tried to turn it on but the red light is blinking

Can you dig up a service manual? It should have the floppy drive pinouts, these 24 pin connectors were apparently from the old MSX computer architecture and it is indeed possible to directly wire it to a 34 pin standard IBM floppy connector.

I'm thinking about replacing the floppydrive with an emulator on my SY77. Do you think that's using the same component as this one, making it not compatible?

Absolutely Useful video. By the way I cannot find any source of the factory voice disk. Could you help me in finding it somewhere in the net? Thanks 1k.

I don't know if you put Matsushita as MatsuSHITa on purpose or because you saw it on a forum styled as such. But they did make some very shocking disk drives, both floppy and DVD (common fault for laptop disk drives are because they use matsuSHITa drives), but now i believe they are under the Panasonic name.

have you done a korg m1 or an op 1 yet new to the subscription

You may have actually fixed the floppy had you left the white belt on. The shop lights may have been interfering with the exposed optical sensor... PS, you should be able buy a beltless floppy drive on eBay.

Bylo milo.

Cut the band and superglue it. you got nothing to lose.

hello.. i hope you can help me.. I have problems with my W7 which i just bought and it has a problem with double tap even though you just tap it once. and also having problem with the display light.

I used to have one of these and I have to replace a bunch of the buttons as they kept breaking off.. I ended up selling the thing.. not worth it.

Yip it becomes a fragile operation the older they get, very risky...

you look like Colin Furze's dad

matsuSHITa indeed

h i marcus. is there a chance i can send in a micro korg for repair?

Hi markusfuller, The 8-bit Guy just uploaded a video involving interfacing one of these floppy emulators with an incompatible 26-pin ribbon cable. Drop him a line maybe?

Why do you wear two watches?

Floppy disc ring- yes, the gay who was trying to restore my Yamaha W7 found original rubber ring from some industrial machines that was using the same floppy disc and he said to me " Well, you are now one of the last people in Europe that have this original ring because I found only two of them - one fore you and one for that company"

Yamahaw lol
