Thanks to you, I was able to successfully install the latest LCD display on my 01/wFD. As advised, the two resistors were regular resistors, not SMD, so there was no problem. This allows us to take advantage of contrast. thank you. I also referred to the power supply board.
Hi Reinard, and thanks a lot for making such an informative video. I am also upgrading/reparing my Korg 01 W FD. I have bought the ROM chips as mine is ROM 28 also bought a replacement USB drive to replace the floppy drive. I have bought a new backlight rather than replace the whole display. I also plan to fix the plastic screen infront of the the display by applying hydrogen peroxide as it is yellowing and I want it to go back to being clear. I want to know where to source the felt that you have used. I would also love it if you can tell me what grease to use on the keybed. Thanks a million!😃
Hi - I don't think the plastic cover in front of the screen is yellowed due to sun+time, I think it is just a yellow tint. It is a terrible thing for Korg to do - should have been clear plastic, not smoky yellow!!
Hi - where you have replaced the screen and added a 2200K resistor to the pins on it, is there an easier way to get the right contrast (roughly level 4) by changing that value, instead of messing with the mainboard adding resistors? I'm about to do this in the next week or so! Cheers.
I have a korg 01wproX, the A flat key has no sound from the middle forward, sometimes it sounds, other times it doesn't, do you have any idea what the fault could be?
Intermittently working key is a clear indication of dirty key contact: clean the rubber dome contacts and circuit board contacts underneath the offending keys with pure alcohol (see my “top 8 synth faults” video -top 2 entry at the end) for details on how to do that)
Does the value change to the resistors apply if you have replaced the display with an OLED? The contrast seems to make no difference since I replaced the display
OLED displays do not have contrast voltage inputs; only LCD displays have. Have not seen 240x64 OLED displays, don’t think they exist. Different LCD make and models have slightly different contrast voltage ranges so it depends… values given here work for the BuyDisplay 240x64 LCD displays…
HI I need a motherboard for my Korg 01W FD by any chance do you have a working one to sell me? and do you ship to mexico? the card is the klm-1528. Thank you
RAM ICs warm to the touch: is ok, are heavily used… audio stage: hmmm… perhaps double check the PSU output on ripple and voltage… also: do you hear strange noise on the audio outputs?
@@reinardsynth6581 Thanks, power supply voltages all good, not checked for ripple but planning on doing that. It's actually stuck on boot screen, was just a quick look on the FLir, work in progress🙂
@@reinardsynth6581 no, I'm sure it's ok because occasionally on switch on the welcome screen appears, however it never goes past that, screen is clear and back light reasonable. I'm going to recap the c94,95 etc and change the fusible resistors since they're discoloured. The caps leaked around that part so I'll tidy that area up with mek.
No worries replying, CZcams is limited, maybe we could connect via email since we're both on the same wavelength, doubtful it's conducive to business due to country constraints/customs etc. I've been interested in synths since late 80s(obviously no money then..); latterly, 2006 bought a broken D50, made a lot of money from parts, bought a few more synths, 95% of time it is profitable to sell the parts, rather than the full unit and pay shipping and possibly (South America) import duties - or er...get moaned about them
Nice video!
Very rare keyboard 01/W PRO
This display was top
Impressive mastery and professionalism, nice from you to share !
oh dear this doesn't look to simple, need to do a similar job on my 01w. thanks for this uploadnsuper helpful. that's a great job you did
Fantastic work. Huge thanks for the part numbers! Will be using this as a reference to fix up my own 01/W.

I want to upgrade or replace exactly what you did in your video ..

Great job ! What resistor should have been used in the display(instead of changing cms resistor on the main board)? Thank you.
about 450 Ohm according to my calculations, living the SMDs resistors (R149 and R147) on the main board untouched.
@@reinardsynth6581 thank you so much for your helpful answer !
@@reinardsynth6581 il works very well. Thank you again !
Master when a fault persists indicating battery low on a korg 01w despite having replaced a new battery. Which ram memory should be replaced?
thanks for the video,
Could you tell me the compatible rate of the LCD display for the Korg 01/WFD?
Thanks in advance
compatible rate? you mean price? about $25-28 plus shipping, see buydisplay link…

Can I ask you about my 01/Wf issue? Thanks

nope, Austria…

On the 01W, is it normal for the ram ICs 18-22 to be warm to the touch, also the audio stage ICs 43-46 and surrounding area are even hotter?
