Minimum Hassle Kits
Replacement displays work with original Roland firmware, however, Vecoven firmware upgrade is required to take advantage of the enhanced display features. All of the display related components are replaced by the new module. The notorious FIP coil, VFD, transistors, Micro-controller, Latch IC and capacitors are no longer required.
JX10 VFD Module – 189 GBP
For stunning performance and “eye candy” whilst keeping the look and feel of the instrument within its original design intent. On request, there is a syx firmware download to emulate the original starburst display using it’s graphics capability.
It is an assembly that is attached to the JX10 Display Board. Includes VFD and mounting screws. Replaces all display related components on the JX10: FIP coil, VFD, Microcontroller, Latch IC & capacitors. Wire not supplied.
JX10 LCD Module – 82 GBP
An LCD character display that is essentially twice the price of a replacement FIP coil, but like the VFD version, removes all the ticking time bomb issues on the Display Board. With Vecoven firmware and “GU280” suport enabled it presents the same enhanced information as the VFD version but in 40×2 character format. Enquire for custom colours but note that the illumination and contrast is not as competent as the VFD because the window on the SuperJX is geared for VFD and is designed for “hidden until lit”.
A single all in one assembly that is attached to the JX10 Display Board. This includes VFD and mounting screws. Replaces all display related components on the JX10: FIP coil, VFD, Microcontroller, Latch IC & capacitors. Wire not supplied.
MKS70 VFD Kit – 197 GBP
A full kit comprising of all cables and mounting hardware for the MKS70. The VFD attaches to the Display Board and a new PCB attaches to the casing using spacers. Replaces all display related components on the MKS70: FIP coil, VFD, Microcontroller, Latch IC & capacitors.
MKS70 LCD Kit – 90 GBP
A cost-effective kit comprising of all wires and mounting hardware for the MKS70. The LCD attaches to the Display Board and a new PCB attaches to the casing using spacers. Replaces all display related components on the JX10: FIP coil, VFD, Microcontroller, Latch IC & capacitors.
Note that the illumination and contrast is not as competent as the VFD because the window on the SuperJX is geared for VFD and is designed for “hidden until lit”.
It is however, serviceable and gives some enhanced functionality that the Vecoven software exploits for VFD in just a 40 character by 2 line display. The very best results can be achieved by ensuring that the window is thoroughly cleaned to get rid of the “soft focus” effect. Like all other displays, works with original Roland software.
Options & DIY
JX10 Flat Cable Kit – 50 GBP
A full set of cables and connectors for the JX10 as shown by the three flat cable guides in the maintenance section. Foil tape is included for the cartridge cable and a 0.8mm drill bit is provided for drilling the Switch Board connector holes.
Vecoven Upgrades With Display Kit
The Vecoven SuperJX ROM update is for existing customers of the Vecoven OS and is only shipped with a Display PCB or Kit. Contact us if the whole package needs to be supplied together with a licence for the Vecoven upgrade. If you have Version 3.11 or later or PWM 4.5 or later then upgrade to current version to get the enhanced display is not necessary unless you want the latest version of Vecoven software. The ROM supplied is not windowed and cannot be erased and reprogrammed.
Voice ROM Upgrade
Ideally, to be “supply current neutral”, voice ROMs can be upgraded to CMOS types to release more current for the new display. This doesn’t apply to Vecoven PWM users, power brick option, or instruments that have had a voice ROM upgrade to correct an issue; When using Vecoven upgrade (not PWM), voice ROM upgrade is sometimes required to overcome a pitch range bug in some early versions of Roland software.
It powers the VFD version of the display independently.
- Reduces burden on the transformer and rectifier.
- Isolates display ground path from the instrument for best noise performance.
- No need to remove the Roland Power Supply Board to fit a power connection.
It fits near transformer on JX10 or near power filter on MKS70. It requires wiring to the mains supply on the output of the power filter, so installers need to be comfortable with mains wiring and PAT test the instrument.
The Power brick is not required or used with the LCD version because current consumption of LCD is very low.
For driving VFD modules, the Display PCB can be purchased on its own. The bare PCB is also available for those who wish to source their own parts, it is all 0805 SMD soldering due to the lack of space available in the JX10. The special Display PCB for LCD is not available on it’s own. Firmware version history is shown here.
Sourcing Your Own VFD
If you enjoy a little soldering, you can purchase the Noritake VFD separately to save money. If you don’t like soldering and still want to save money, then post it to us and we will do the soldering for you when purchasing a Display PCB. This is easier to do in Europe and more difficult in USA, contact us for assistance.
A guide explaining how to source and attach a VFD to the Display PCB for MKS70 or JX10 is here: VFD Sourcing and Attach Guide
VFD can be purchased via Telephone (they don’t respond to web or email orders!) from your nearest Noritake office as each office carries some stock. See the detailed guide on how best to obtain one and solder it to the board. When buying your own display from UK, expect to pay approximately 95 GBP inc post & tax for a GU280X16G-7806A VFD. Price can vary depending on exchange rate and country of purchase.

Based in UK
We are based in Wrexham, North Wales, UK and really happy to help out users and keep the Super JX up to date, it is such a magnificent sounding synth.
Items ordered are all sourced and custom made to order, in very low volume. For the very best reliability, all parts are brand new from approved distributors where they can be traced back to original manufacturers. We can supply a receipt on request (non VAT, Sole Trader only).
The development time and supply of parts and kits is just a hobby and is not intended to make any money. When GU280 displays are purchased, the cost has to include UK VAT at 20%, so apologies for the high cost when including the VFD in a full kit, but this is offered if installers have difficulty obtaining it or just want minimum hassle.
