Yamaha DX7 Restoration/Refurbishment
Вставка
- Опубліковано 4 жов 2024
- In 2022 I bought a vintage Yamaha DX7 keyboard. It was in a reaaly bad condition. The previous owner connected it on a 220V power line (The keyboard is 110/127V) and the transformer burned. He tried to rewind the transformer but it was a really bad job and the kayboard was still not working.
Althrough, after changing some voltage regulators it was possible to bring it back to life. The transformer was changed anyway, because it was heating up and making an anoying noise.

My personal DX7 was full of drywall and had gunk all over the exterior before I restored and modded it (SuperMax+ 3.0 modchip). I didn't remove the surface rust because then I would've had to paint it, and I had already spent a lot of time and effort on it. Some of the buttons still have issues, so I think I need to hit them with some contact cleaner. Otherwise, it's been a joy to have.
Hi @lars1588.. thanks for your comment. About the buttons, i had something similar with the NO button and two or three othres, can't remember now. At the end it was a bad contact in one pin of one connector (probably by high number of assembly/disassembly by the previous owner). You should check if there's a problem on the soldering of those buttons, also a problem on the button itself, that you can check with a multimeter. In my case, all buttons passed on the test and also I resolder the pins, so started to find where else there will be a fail point. Looking at the schematics, the buttons failing have the same common connection...
@@adailtonemerick I plan on testing the continuity of all the buttons and wiring at some point. For me, buttons 8, 16, 24, and 32 all work only occasionally, so they probably all share a common connection somewhere that is faulty.
@@lars1588 According the schematics, Buttons 8, 16 and 24 shares the same signal pin (S8). 32 is the pin (S16). Maybe you can check the buttons and the connectors C3 (Buttons board) and C16 (Main board)
That was a fairly large project. Glad you were successful bringing it back to life.
Yes... months of hard work just on free time. Hard to find some parts like potentiometers, but it is done. Thanks
Fantastic 💗 DX7 black édition 🙏👍 very good restoration my friend 😊
Thank you.
very nice video and lovely how this DX7 got a second life ;) and i also liked the music btw ;)
but i would have appreciated some more detaillled explanations of your steps; but with the very fast time lapse only it is almost impossible to understand what is happening in detail, where to pay attention etc. ... maybe you could make this into a (of course much longer) very explanatory how-to video :)
Meus parabéns, ótimo trabalho eu também adoro reformar e construir as coisas, nos últimos 6 meses retornei a tocar teclado, a 22 anos sem pegar em um. Comprei um Ensonic MR76 com problemas na placa principal e com muitos arranhados e pintura mal feita por terceiros, eu mesmo reparei a placa e revitalizei a pintura ao mais original possível, agora ja comprei um Korg Triton Le e um Roland Xp50 e estou fazendo o mesmo trabalho de reparo e revitalização. O DX7 é um sonho pra mim devido aos pianos eletricos, se Deus quiser um dia terei um. Parabéns pelo video.
Olá, obrigado pelo comentário. Eu tive um Ensoniq SQ2 que em princípio estava sem som. O difícil deles é que não se acham esquemas. Contudo, no manual que encontrei, vi que eram muitos parâmetros e resolvi fazer um "factory reset" e voltou a funcionar. Estava bem sujo e com adesivos. Não precisei pintar, mas foi osso remover todas as colas. Um abraço!

Fantastic work, restoring a classic. Hard to believe it’s over e0 years old
Thanks... really very old and working fine
Great job! I would make sure you change out the rectangular gold capacitor on the power supply. They have been known to catch fire.
It was changed
Cool video. Thanks for the technical Portuguese terms. My wife is from Brazil, so I need practice :D Love the DX7!
Hi! Thanks a lot! Great! Where are you from?
@@adailtonemerick We live in California, but my wife is from Rio
@@philipstrangio4887 I also live in Rio state, at the north part of the state.
I would never have used spray paint on that, I def would have prepped it a bit better though if I did, a paint job regardless of the medium you use, the outcome always depends on the amount of prep before laying basecoat, the amount of orange peel in the coating on the back alone is pretty rough looking, I would have at least tried to cut it / wet sand it / buff it out before making a video about it to be fair, internally everything else wasn't bad for a resto, but the paint job was not good at all, shame because you could have had someone prep it better and shoot it with a real gun and the end result would have been night and day better.
Just kind of sad to see such an iconic digital synthesizer get a cheap makeover as it were.
Hi @nkogliaz. Thanks for your comment and based on the video only, you were possible right. Although I have painted the lower part with srpay as seen on the video, but it was really crappy at the end.
So I decided to hire a specialized car paint company to redo the painting on lower part and do the front panel (and as you are a detailed viewer, you noticed that I didn't hava a video painting the front panel 😉).
You use the tools you have sometimes.
Personally, if had to do this, it would be more money than it’s worth. Removing all the prior oxidation. Power coating the metal parts. Color matching all the original colors and decals.
If I had a DX7 in this bad condition, I’d look for a better cosmetic and electrical condition unit and call it a day.
I respect he did it at all. It’s a lot of work.
It looks great. Did you paint it black or is it a dark brown like the original? I can't tell since the DX's look very dark in room light. In turn in sunlight they look completely brown.
Also were the prints originally stickers? I think they were painted on, since you never ever see them peeling off on even the worst condition ones. Or maybe they were, but they don't have the clear parts at all on the sticker.
Hi, thanks for your comments. I took a help from a friend that paint cars. I guarantee you it is not the original color, but it was a dark brwon near to the original.
About the stickers, I made them in inkscape and print it on transparent vinyl (specialized print company).
Karl Casey - Last Stop... Combina perfeito com o vídeo... Cara, o DX7 ficou muito bonito... Onde fez o desenho do painel?? Saudações do Brasil
Olá @thenetware1, tudo bem? Obrigado pelo contato. Eu fiz o desenho do painel usando o Inkscape e depois enviei para uma gráfica fazer em adesivo vinil transparente. Tive que converter para Corel Draw, que era o formato requerido pela gráfica.
Ottimo lavoro, sto cercando anch'io un DX7 da riparare. Se non ricordo male, il colore originale della tastiera era marrone cioccolato fondente che non si trova nei negozi. Bisogna farselo fare in colorificio.
Grazie! Sì, e questo è stato il mio caso. Il colore era vicino, ma più scuro
Great job and awesome music, well done!
Thanks @MrPrzekojot. The sound track isnt mine: ua-cam.com/video/g6hY7dB54bc/v-deo.html
Wow... impressive ...
Hi,
How did you print the white adhesives?
Thanks for sharing your work.
Well done.

Hi, thanks.
I just found a company here in Brazil that do this type of work.
Complimenti per il lavoro molto ben fatto , una curiosità, dove hai trovato gli adesivi ?
I made it in Inkscape/Corel Draw and then sent it to a third party company for printing on transparent vinyl
@@adailtonemerick my compliments for a job well done
Genial mano! parabens
Obrigado!
Great job!
Which transformer did you change it to? I am looking to convert a DX7 from 110v to 220v.
Hi, thanks. I bought one in a marketplace here in Brazil that has a 110/220V primary and a secondary of 6,3V-0-6,3V and 15V-0-15V, 2A. I used the support from original transformer and some plastic mass to fix it on the support.
This is the link of transformer specs:

@@adailtonemerick Thanks - I’ll see if I Can find something like that.
Excellent! How many hours did you spent?
Hi. Thanks. In total it was about 80 hours to do, using just free days or free time. The fine painting job was made by a friend that works customizing cars.
Nice project! Well done :-)
Thanks
Paint work is awful
Its really terrible to do that. I just paint the "primer" and hire a more specialized guy to do the painting, after trying to make it by myself and fail miserably ahaha
Ma per essere ridotta così dov'è che stava, in una discarica? Poverina, è vero che è un "oggetto" (per modo di dire) ma ridurla così....
Il proprietario forse è stato molto negligente
Would you fix mine
Well... where do you live? At video description you can find my mail
