12:46 - 3. Capacitor Fiasco
15:42 - 4. End Result
My Roland JD-990 gets a well deserved makeover by updating it's internals and installing a brand new LED display screen :) Screen is incredibly difficult to capture faithfully on camera, mainly because it appears a lot less saturated then in real life.
In reality it is a deep, deep, rich, lovely blue color that matches the device perfectly. Best reference to the actual real life color can be seen in the image displayed at the end of the video.
Replacement capacitor specifications are 10V, 100uF. - เพลง

Years later, still a good resource for a tear-down. Thumbs up.
Congratulations! The 990 is deserving of love.
Many Thanks for your video. Following your instructions, I have changed the screen of my Roland JD990 and refurbished all my SR- JV80 Expansion boards with new capacitors. Everything came out as expected.
I'm glad it helped and that you managed to update and future proof your synths :)
Great video Vojislav. I appriciate your happiness for the JD-990. And I feel the same about mine. Have to check the cap and also ebay for a spare display ...Thanks for the inspiration!
A+ for commentary and good microphone placement. A+ for well lit video, A+ for the subject... the JD-990 is very special and happy to see there is finally a new display solution.
Really useful, helpful video, thank you so much ☺️☺️
I own 2 JD990's which I've bought once new. (incl Vintage & Orchestral Exp) From all the synths I've owned and sold over the 30 past years (quite some exotics like M12, Wave2.3, and many more) they are the only ones I will never sell. And I repeat NEVER. Alongside the Jupiter 8, the JD990 is simply the best (sounding) digital synth Roland has ever made. It is a true WONDER machine that reproduces awesome sounds on condition you know how to handle and program it. Hard to find and becomes more and more expensive. A good alternative is the JV2080, almost similar (also to program) but 32 Khz.
@ sK3LeTvM1… I agree the JD-990 is simply awesome. I too am fortunate to have some coveted vintage classics, and have also been a close follower of Roland's better creations going back to the 80s. In fact my favorite synths over all are my MKS- series analogs (2-80s, a 70, and a 30), and my mint JD-800 and JD-990s. I'm a bit surprised at times how little known and under-appreciated the JD-990 is… that might be in part because I'm older now and was around when this model of synth was new & current. For the price they can be purchased now, they represent an amazing value in an incredible sounding machine. As a side note, I will say the inclusion of 8 audio outputs (4 stereo pair) seems like an odd choice for this module given the polyphony restriction… would have been more useful on some other Roland products.
+ 1 here !! 👍
Lovely guide - thank you!
I just followed it to replace my JD990 display - the hardest part is getting the screws off the display raisers - they are very tight, so finding a screwdriver that lets you get enough torque, but with a small enough head, was the tricky part! Thanks again though, you gave me the confidence to tackle this on my own
Great tip on creating a new contact point if the pad comes off , thanks
Well the Black screen is in and i used tiny dots of gasket sealer to bed the screen in went relay well. Capacitor done, came off ok and new one on nicely but i almost put it to close the the hole but just got away with it and the board fitted back in. Happy JD990 with lovely black screen. Thanks for the tips.
Very useful vid. Thank you. Subbed😊
wow! Thumbs up - good news for JD-990 owners! My Display is now very weak - but with the new one you will have a complete Studio Light :) - I will change my Display - like the Blue Look.
Thanks for sharing this video. Subscribed to you channel
Just got my white on black display. Only issue i had was the mounting screws for the display. mine were so tight, my screws were starting to strip. i recommend that once you get the older display off, use a 5.5mm socket to get the brass double sided mounting nuts off. thanks for the video!
Thank you for watching and for the tip! :)
Hello Dave, thanks for mentioned this possible problem. I have question for you, I need to refurbisch a JD-990 for someone and I want to ask you if you maybe want to tell me where you bouth this display. I can find some "cheap"products but I'am not so shure about th e quality. Looking forward to anwer. Regards, Ivo
Nice display, i just bought the black one :) i use A Roland A 01 with the jd and it also has a black white display so should look nice. Good vid.
I think an Custom LUX (Negative) LED Display is looking much better.
I have the for my JV2080s and my 990.
An old friend ( he is 87 )installed them for me.: Thank you Wilhelm! :)
The are very eye friendly and not so expensive.
Hi! Could you please help, where can I buy Custom Lux negative led display for my JD-990? Thanks!
@@nanemarnanemar67 eBay. a Shop from great britain ... England...
when is part II coming? great great video thank you very much! :) and can you say me the model name of the display?
Hello and great video w/thumbs up by the way.
My question is, does this procedure of replacing LCD display the same as the Roland XV-5080? My screen is very low lighting.
Thanks.
5:59. That is a gorgeous piece of music my friend. Your work? Is there a full track please?
Again, great video. This time I'd like to ask about the failed firmware update. I've updated a couple of my older synths with newer firmware on ICs. Never had an issue. You didn't address the failure in the vid. Can you tell us if you were able to isolate the problem? Seems odd that it would boot up and display the correct ROM version, yet stall/hang on normal boot-up.
Good to know, thanks.
A boutique version of this would be great.
@@MyDeepGuide I always thought the V-Synth version sounded very clean compared to the D50 but believe there are two modes, so you are saying the Boutique version is even cleaner?
Jd800 just came out yesterday :)
Are there any other displays that will work for the 990? I am fortunate, my display is good, however the new LED displays are quite an improvement over the back-lite. Late last night I replaced the screen with a modern LED on my JV-880 - which is similar to the install here.
How to transmit or dump utilzing sysX for Roland JD 990 would be yet another great video.
At: 10:08 the camera does not pick up the edges of the characters because of the display lens which diffuses the output of the LEDs.
can you post he contact for the guy who makes the displays
Hi! Thanks so much fo the video! Question using 100uF 25v or 16v vs 10v would be an issue?
Higher voltage isn't an issue, as long as it's not something crazy different. Capacitance has to be the same.
@@MyDeepGuide Awesome, I got a kit but is made in China, it as 100uf 16v, people say Japanese ones are the best. I bet I’ll order some Nichicon🙂 thanks a lot for your advise.
Hello, i need to do replacing the screen also. I saw you video and you did this verrywell. So I want to ask you if the replacement screen has the same voltage ore should I need to replace ore adjust the input voltge for the screen. I saw you did need to that ? Also can you send me ( if you want of course ) youre suplier for the screen.In advance thanks and keep up do some more good upgrades. Regards, Ivo from Belgium
I have installed the Super Editor for the JD-990 (ctrlr.org/roland-jd990-super-editor/) and not able to see the JD-990 however all the synths which have a USB driver show up in the list of connected devices for both MIDI in and out. Please advice. I am using the M8 from MIDI Solutions. The one out from the M8 is going to the MIDI in into the JD-990. I tried bypassing and connecting the MIDI in and MIDI out directly to my USB to PC adapter, still nothing shows up in that app. I am able, using the M8, to control my rack modules from any Keyboard.
At: 6:00 - again, is that you music? Just a few chords, but as a mentor stated to me, poetry is words often placed in sequence which are not usually seen.
Is the opening of this presentation your music? If so, dude, you are very creative. Thumbs up.
@@MyDeepGuide Impressed. My background in taste and in style stems from the Baroque period.
I did all the upgrades that you did and everything came out perfect except when boot up the display get stuck at the introduction screen. I have two 1.05 chips and it does it on both. When I switch back to my ver 1.00 chip it works fine.
You just need to do a factory reset after swapping the OS. Then it will boot up just fine :)
@@MyDeepGuide Thank! It worked. I also put a new battery in it.
Glad to hear it :)
Hey I bought a JD-990, replaced the motherboard battery. Display just has a line across the screen. Would your replacement fix mine or do I have a different problem?
I have no idea, it really depends on what your specific case might be. Do you know if the display ever worked? A line across can be a broken display, or a faulty display connection or so many other things. I can't diagnose it for you, sorry.
@@MyDeepGuide No idea I bought it used. I made a reddit post here with pic. www.reddit.com/r/Roland/comments/os1c35/roland_jd990_screen_prob_how_to_fix/?
Well, then I can't help you, because it can be anything. You can test if the synth produces sound by pressing the volume button. That is how you audition sounds, and the big dial is to flip through presets. So that would be a starting point to see if the synth is alive or not. After that, you have to trace and troubleshoot on your own. Good luck! I hope you get it to work and serve you well :)
Hi, nice video! Can you tell me, why need to Replace capacitor?
As I said in the video, they can spontaneously explode and ruin the expansion card.
@@MyDeepGuide
do you think that everyone needs to change?
It's up to you. I did because i didn't want to risk it.
@ Vojislav Dimitrijevic
I want to say how fortunate I feel to have stumbled upon this vid late last night. I have (4) JD-990… 3 of them have the 04 Vintage synth board installed. The 4th JD unit is a bit "scruffy" cosmetically and I got it for an amazingly low price from a local musician looking to dump it for some quick cash… I'll be selling this unit.
Anyway… my 3 JDs' displays are still working fine, but i will be upgrading to the displays you've now turned me onto. I've gotten in contact with Matt who is Steven's associate. Matt tells me he runs the store on "Reverb", and Steven runs the eBay store.
WAY more important to me though was the heads-up i got from you regarding the capacitor on the expansion boards. HOLY SHIT! I had NO IDEA that disastrous surprise was likely just around the bend for me. SO glad to know about this BEFORE any/all of my 3 expansion boards are rendered useless.
In the video (which i believe i watched carefully) you say "should be replaced with another capacitor"… if i missed it i apologize, but could you please name the specifics of the capacitor replacement for the expansion board? I want to make this mod ASAP before any of these boards get ruined.
btw… I subscribed to your vids… thanks.
I'm getting Steven's displays for my (2) Roland A-50, Wavestation A/D, and Yamaha TG-77 to start with. All the pixels are still active on my JD-990s and quite readable, so those replacements will come a bit later for me. I've viewed photos of the white on Black display installed in a Kurzweil K2000R on their "Reverb" store front. I can already tell you I prefer the blue… blue is "happy" and calming. The white on black is kind of "clinical". Thank you for the heads-up on that though :-)
Regarding the eprom/firmware update, what actually is dissapointing? It looks like you updated it just fine, not clear what the issue is/was?
It didn't boot initially. It took another reseating and then it worked.
@@MyDeepGuide I keep trying to get the new frimware rom in, it keeps bending, pain in the neck.
@@MyDeepGuide V nice job on the screen, where was it from?
FWIW I found that those chip-removal tweezers tend to twist much too easily, and have a better ROM removal tip: bend a small, old flat-head screwdriver 90deg at the head (leaving it shaped like a garden hoe), and insert the blade between the end of the ROM and its socket, then gently lever it, working each end of the ROM out gradually. This exerts no undue stress on the PCB - it only prises the ROM from the socket - and does not require much space (only some vertical clearance).
Hi mate,great video. Please where can i get this nice blue display for my JD? thanx
Look on eBay. Someone is selling them for $178 US.
And where you found Firmware Upgrade?
On eBay.
@@MyDeepGuide what is the name of?
Just search for it, I'm sure you'll be able to find it if you just try ;)
dont have background music in a video with narration.. hard to hear you and its annoying.
