I always thought it wasn't that bad to replace screen on a synth like this. Guess I was wrong 😂. Luckily, we have folks like you who take the extra mile to document the process step by step!
Thank you so much for creating this guide! I have ordered the same display as you and followed your video and a PDF guide. After about 5 hours the SY99 was equipped with the new display and reassembled again. It's a lot of work, but really worth it!
Great salvage! Reasonably easy if you know what you get into and have all components and tools in house. Once fixed a multi fx pedal and just turned out to be a loose pcb, literally a screw loose 😅 And replaced a battery in a Boss SE-50 fx module 😎 My first endevour into taking stuff apart...
You're right, there's no actual technical knowledge required for this fix. But män, it eats up a lot of time. Doing this on EX5 was a walk in the park compared to this.
I just bought this synth yesterday for its Rhodes emulation, it is close and sometimes better than the original since Rhodes EP's are not all in top condition Unbeatable EP!.
I just replaced the screen, battery, and upgraded to a USB emulator drive last winter. Original owner since 1992. Also own the 77 since 1990. Love them. Opsix is easier to program but there AWM/AFM is classic.
@@mr_floydst Same here. In 1991 if I wanted the SY77, I would have needed to wait more years before buying my first car. I got the SY55 instead and my car in 1993. I really love my SY55 (got all seven WAVE/DATA sets), but I would LOVE to have an SY99. They are still an awesome synth in 2023.
@@EgoShredder You are so right… both the 77 and the 99 still have a lot of power left in them… especially the 99 as you can load samples into its non-volatile memory. I nowadays have a Korg Kronos X 88 which is a real beast but it’s actually nothing more than a PC, running a special Linux OS a DAW, 9 plugin synths and some effect plugins. So it takes a long time to boot while the SY’s are ready to play within a few seconds. I do miss my 99 and 77.
I have an SY99 in impeccable condition. I now need to replace the batteries, so thank you!🙏🏻. BTW: The LED’s in the display were never bright. If you saw it new, you’d think they were bad, that’s how dim they were/are. I don’t understand why Yamaha thought that this was OK. 😉 I need the original floppy drive, I have 100 Yamaha floppy’s with different patches on them.
Man, am I glad I did find this EXCELLENT tutorial BEFORE taking my SY99 apart - saved me hours if not days and certainly a lot of frustration, let alone possible damage to the synth! Thanks a a big lot Floyd! The SY99 is an absolute beast of a synthesizer, perhaps the best-sounding, most comprehensive, most in-depth vintage synth i've ever owned, whether digital or analog, so it's absolutely worth the effort of thorough maintenance, re-capping, replacing worn parts, installing USB, etc.
Hi, thanks for your kind words! This video was the most physically strenuous I've made (so far). Man. In those vintage synths, you knew what you got for your money just by counting the parts inside. ;-) Yes, this is one of the best FM synths ever made. It's successor, the EX5, dropped the FM engine but came up with the very unique FDSP engine. It's another often-overlooked classic.
Wow, thats no easy feat! Well done! I have a mint condition TG77 that really needs a new screen, but you just convinced me to pay someone else to do it for me! 😁
Ahh, the glorious SY99. Never has an FM synth sounded better. Congrats with the purchase. Reminds me that I got to fix the keys on my SY77 soon. Managed to loose my SY77 on my D-50 when i was packing, a case of an unstoppable force meeting an immovable object, both synths got several broken keys out of the incident.
I owned both an SY77 and 99 at one time. You may make the mistake, thinking the 99 was superior to the 77 and in most cases you’d be right but there are sounds that you just can’t create on the 99 that the 77 excelled at, just because of the older but grittier fx processor in the latter. (SPX90). The 99 had an SPX 1000 which obviously sounded much more refined, clean etc but for the more aggressive sounds, the 77’s SPX90 was unbeatable. The SY99 is one of my favorites in the arsenal of previously owned synths.
Noice video Floyd! must've been crazy filming this, cant imagine how long it took too unscrew and move around inside the SY99. I've always wanted a SY99 :) such a BEAST SYNTH!
It was the worst. :-) One and a half days taking the thing apart and rebuilding, and then 2 days of editing, writing a script and reading it out aloud.
Wow Floyd! It might have been easier to just build a new synth! lol. Nice job! I couldn’t do it. I’d like to point out to everybody Floyd is doing this on his sofa! I’ll bet your knees hurt afterwards as well! I have regular visits to Harbor Freight just to get seating for this type thing. Or I used to. Thank you for filming all this! I know at least one project I won’t be taking on! My Kronos 88 needed a new hard drive so I purchased everything and ended up buying a Nautilus 61 to midi it! lol, works great but my bank account is in pain!
@@mr_floydst it is probably because I've owned it since almost new, but I'm a trained technician so I should be okay unless there's a surprise waiting for me! 😀
Oh god, I feel like Homer Simpson when he's watching that DIY foundation repair-video. I've always thought opening up the Roland D-50 was a hassle, but this takes the cake. I hate that synth developers of this era stopped using hinged top covers...
@@mr_floydst Agreed. My display has developed some contrast irregularities on the top line, and I wanted to take a look at the procedure of changing it out with a new one. There's no way I'm doing this until it's absolutely necessary...
It's crazy that you have to take it apart completely to reach the screen. I've only opened home range PSR once in my life to clean the key contacts, and it was like 1/10 of the complexity shown on this video.
@@mr_floydst Yes understood! I thought you might know offhand. Sorry for the trivial question but it’s actually important for me because I have to provide someone with an lcd and I don’t want to get the length wrong and don’t have an original Yamaha display in order to measure it. Thank you very much for answering
Hi, I didn't measure that personally. I can only speculate, but as the floppy emulator doesn't need mechanical seeks, it should be _slightly_ faster than an actual drive. But all in all, the speed of the transmission is limited by the floppy drive interface/cable/protocol. That speed is 250 kiloBIT per second on 720kb drives and 500 kiloBIT per second on a 1,44MB drive (31,25 Kilobyte/s and 62,5 Kilobyte per sec respectively)
Hello, I am from Venezuela and I need the technical specifications of a screen for the SY77 keyboard, if you have the possibility of providing it to me, I would be very grateful since I have to order the one for my country from you.
Hi, thanks for watching! I'm afraid I can't provide you with technical details, but there's a link in the video's description to some shop that has replacement displays. Here it is again: www.synth-parts.com/search?sSearch=sy99 They should be able to send it to Venezuela, but I'm afraid it'll add onto the already steep price. Hope that helps!
In July 2021, I replaced the backlight in my Yamaha QS-300 which uses the same display as in the SY77 / TG77 and others. Cost approx £15 and was a lengthy procedue like in this video, although nowhere near as many boards to unscrew. The online guides on how to do this resulted in a non-working display, but once I soldered in a couple of wires and connected to another power point on the motherboard, it all sprang to life and works fine. I was sweating cobs like Floyd, as the weather was very hot at the time.
It looks similar, but EX5 has a different approach to synthesis. This here is a mixture of (rather modest) sample based synthesis and FM. EX5 doubles down on samples and throws in virtual analog, FDSP and VL.
@@EgoShredderYes, so it is. One definitively needs both! 😊 I had the SY99 first, with the intention of selling it after getting the EX5, but they are both still with me after many years. Even my Kronos 88 couldn’t quite replace them, although technically it does. By far.
Finally you have an SY99! Congrats! Try this sysex sound tweaking with Novation SL I/II controllers (there are more videos about). It's something you can't do with anything else: th-cam.com/video/QWlkseQH1Jw/w-d-xo.htmlsi=tpWKau3dRnaF59oo
Thanks for sharing this idea - I'll try to include it in my next video on this synth. You _could_ do this with the Reface DX and a "Grid" controller as well (for example) - but it's amazing this more than 30 years old machine pulls it off effortlessly.
Horrible. Absolutely. And I was nearly sweating when I didn't see you putting a control cable (?) back through the hole in one board... It wasn't mentioned, so seems it was just re-routed :)

One of my favorite synths ever!! thank you for sharing, a video about the functions of the Floppy Disk Emulator could be great!
Thanks! I'll do that in the coming months (there are other topics on my agenda first)
you are a brave man Floyd. sounds great and now you can see the screen. great idea to replace the floppy drive with an emulator.
Thanks ;-) The floppy emulator needs a custom firmware for working correctly - I'll cover that later...
not for the faint hearted! well done and congrats on the 99 fun video.
Thanks! It's like a DX7, but with samples and without the noise.
Thanks man ! I owned a sy99 back in the day and It was awesome! Kudos for your fine work.
