NIVONA Caferomatica 830 Coffee Machine: Damaged Display Repair, AliExpress Replacement

Best answers

How can I replace the damaged display in a NIVONA Caferomatica 830 with an AliExpress part?

You usually cannot swap in a random AliExpress display: the original module was a special SSD1303T10, and generic substitutes like BL-12864G2 ERNHn/SPD0301 were reported not to fit or to use a different controller [#17062856][#17833740][#18455044] The practical solution that finally worked was to buy an SSD1305/SSD1305Z OLED module from AliExpress and use one of the adapter PCBs developed in the thread; with the reversal fix, it works like the original and no missing-line problem appears [#18305185][#18233157][#18358600] For the J4rek adapter, the tested parts are C1=C3=100nF, C2=4.7uF, U1=SN74AHC1G00DBVR, U2=CD4071BM, and U3=CD4078BM, and the display is soldered directly to the adapter, which then plugs into the machine’s original 20-pin connector [#18959999][#18279191] If you build the simplified version, the TPS61045 stays on the original board; in the full version it is included on the new PCB [#19025589][#18959999]

    Hello Peter,
    thoroughly wash the board with alcohol and carefully check the soldering points with a magnifying glass. You can also try to move the pins of the ICs with a small screwdriver (cold soldered joint).

    Hi friends,
    I’m a little lost I tried a method of J4rek nivona v2r1, and I got the wrong reference of components and pins, and now my lcd doesn’t turn on anymore.
    I will buy a new screen and I want to know the components and their size.
    I’m not very familiar but I’m trying to do well. I want a clear explanation for a beginner for the J4rek (nivona v2r1 ) as simple and clear as possible. I see here a lot of solution but I am lost.
    Thank you very much.

    Similarly :) It is best to clean the soldering points of the circuit with a braid, flux and gently tin the soldering points on the board. Put the system on them and after heating it should arrange itself nicely.

    There are these states among others.
    1. The display is black but the machine makes driving noises when turned on.
    Here the fault can be found in the display module.
    2. The display is black and there is no driving noise.
    Here the fault lies in the display module or the motherboard.
    If you have a working display, the error is easily attributed.

    Initially, I attached a display with no additional layout and the image was just inverted. I ordered the tiles from the project, soldered everything and now it does not work, the display is dark, no coffee sounds. In my opinion, everything soldered well. When I measure the voltage + 3.3 V and GND, I have about 1 V and it's strange, because previously everything was going only the image was reversed.

    It seems that it is not well soldered or some circuit / component is damaged. This low supply voltage indicates an overload or short circuit, so the main processor does not start, so there is no noise of the machine. I propose to unsolder the plate and measure the resistance between pin 1 and 2 (VDD) and 1 and 3 (VBAT).

    I wanted to order a circuit board (the NIVONA SSD1305 ADAPTER V1r2 gerber files)
    Unfortunately I got an email from support.

    Screenshot of PCB design software showing an issue with 0.4mm holes.

    Hi Sir,
    Well got your order with many thanks~

    Sorry to bother you, but there is an issue that we want to confirm with you before proceeding.

    As shown below, for these 0.4mm holes, they are too close, we can't make them.
    Coud we change them into a cutting line to proceed?

    Your early reply will be highly appreciated!
    Thank you so much!

    Is it okay or must I have done something wrong?

    Good Morning,

    So that I understand everything.
    I bought 1x small board and 1x large board from J4REK version.
    If I use the old board from the display, do I take the small circuit board and only have to buy the components?
    If I throw the old board away from the display, do I have to take the large circuit board and put the components on it?
    Is it right?
    So you have 2 options right?

    Two green printed circuit boards of different sizes on a light background.

    1. Option - small plate plus replacement of the oled on the old top plate.

    2. Option - we only replace the top plate (new oled plus smd elements obtained from the original top plate).

    Hi guys, many thanks to all who helped my coffee machine work again, especially Amigos and Satanistik. I was able to manufacture the display replacement using two different displays. I met a few problems including low voltage due to resistor 120k (solved by lowering the resistance down to 100k) and breaking the display while trying to stuff it into case :-), but finally everything works fine and I have a few spare satanistik/amigos PCBs and a bunch of components.
    Is anybody interested in buying the enlivened PCB with display and 20pin male connector for the main module board for let's say 99€ plus transport fee? Alternatively if you sent me the whole Nivona display module, I can replace the PCB+display for you, for free :-). 5€ from order will be sent to Amigos/Satanistik if they give me the permission. Little patience will be needed as I currently have no spare display but I can order some. I live in the Czech Republic. You can sent me a private message or mail to miji2 at volna.cz

    Hi

    I have been treating the project as a challenge that has lived to see a solution, and even already several solutions ;) I have not made a profit from it and do not intend to. If you manage to profit from it then "cheers" :) I am glad that we managed to do something useful together.

    Hello
    I used the solution from the Dragon. I cut the pins connecting the boards, mounted the adapter (a system to invert the image display) and added a 20pin plug socket to the display board and a new display. Now it works like "new". Thanks to Smoczy.

    hello everyone
    I come back to your help once again. I fixed my screen last year with an ssd1305 and the pcb modifier from Smoczy. so I bought a new machine to repair and I'm looking for a pcb to fit on the 1305 if any of you have one to sell I'm a buyer 🙂

    Image of a PCB with an SSD1305 display module mounted.

    Thank you, have a good day

    Hoi,
    I can send them, you just have to pay for the transport.
    I think I found a dealer who should actually have these.
    After that, these will cost no more than 40 euros and are available worldwide.
    I have already tested everything, also with the reverse image content.
    But two years ago I put the project on hold again.
    So, as I said, the subject will soon be resolved for everyone.
    The offer for hobbyists
    https://www.dicofema.de/de/nivona-nivona-disp...erie-intake-elektronik-defekte-vergleich.html
    The offer is for people who want to drink coffee straight away and want to switch off their devices properly with the on and off button, so the display lives again for almost forever.

    Yes, I meant the small ones, but I already made a PCB according to the design of this colleague. The machine has changed LCD to another one and has been running smoothly since then.

Topic summary

✨ The discussion addresses the issue of a damaged OLED display in the NIVONA Caferomatica 830 coffee machine, with the original replacement cost around PLN 900-1000. Users confirm the original display uses the SSD1303T10 driver and is a 128x64 pixel OLED module with a 31-pin connector, which is now rare and discontinued. Attempts to find direct substitutes on AliExpress or other markets largely failed due to incompatible controllers, pin layouts, or mirrored image outputs. Alternative displays such as BL12864G (yellow OLED) from SOS electronic (Slovakia) and similar models from Japan or Russia have been used successfully but require delicate desoldering and soldering of the 31-pin ribbon cable, a process recommended only for skilled technicians. Some users developed or are developing adapter boards to use newer SSD1305, SSD1309, or SPD0301 controller displays, which have different pinouts and may show mirrored images or missing columns, requiring hardware or firmware adaptations. The community shares detailed disassembly instructions for accessing the display module, emphasizing careful removal of the front panel and soldering challenges. Some users report successful repairs by cleaning pins or replacing capacitors and diodes on the motherboard. The discussion also highlights the scarcity of original or compatible displays, the need for specialized repair skills, and ongoing efforts to create adapters for newer OLED modules to extend the machine's lifespan.

FAQ

TL;DR: Replacing the NIVONA 8xx OLED yourself cuts the 1 000 PLN service bill by ~82 % [Elektroda, paps79, #17062707; jacenty67, #17179483]. “It shines like new” once a SSD1305/0301 panel is fitted. Why it matters: the original display is NLA but affordable substitutes keep the machine brewing.

Quick Facts

• Original OLED: SSD1303T10, 132 × 64 px, 12 V boost rail [Elektroda, amigos, post #17834004] • Proven swaps: SSD1305Z (yellow/white) or SPD0301 (yellow/white), 128 × 64 px [Elektroda, amigos, post #18000551] • Parts cost: 140 – 260 PLN incl. PCB, vs. 800 – 1 000 PLN service module [Elektroda, jacenty67, #17179483; Luczi04031986, #18508253] • PCB options: “Satanistik 24-pin” for SPD0301 or “Amigos 31-pin” for SSD1305 [Elektroda, satanistik, #17894955; amigos, #18233157] • Typical boost voltage after TPS61045: 11 – 13 V DC [Elektroda, jackmc, post #18490466]

Which replacement OLED works without missing pixel columns?

Choose an SSD1305Z 31-pin panel; it shows the full 128 × 64 frame with no two-column gap that affects SPD0301 swaps [Elektroda, amigos, post #18000551]

Why does my SPD0301 screen show a 2-pixel blank strip?

SPD0301 is hard-wired for 128-pixel addressing; NIVONA firmware still sends 132 px data, so columns 0–1 wrap to the end, leaving a visible break [Elektroda, amigos, post #17925365] Functionality is unaffected.

What PCB adapter should I order for SSD1305?

Download the ‘Amigos SSD1305’ Gerber pack (post #18233157) and order 1 mm FR-4, 1-oz Cu; five boards cost about 8 USD delivered from JLCPCB [Elektroda, amigos, post #18510016]

Do I need hot-air to solder TPS61045 boost IC?

Yes. The SON-8 package sits under the board; use 250 °C air, flux, and tweezers. Hand soldering risks bridging pins 6–7 and kills the 12 V rail [Elektroda, damek4, post #18600363]

Edge case: display stays dark after swap—what to test?

  1. Measure VCC at JP1 pins 1-2; it must be 3.3 V.
  2. Check boost output at C4/C10; expect ~12 V.
  3. Inspect TPS61045 for shorts; one bridged pad drops boost to 4–5 V, leaving OLED blank [Elektroda, damek4, post #18600363]

How to flip the mirrored image on SSD1305/0301?

Use the 2-IC inverter: CD4078 combines command bits, CD4071 forces D0 high when opcode A0h is detected, plus 74AHC1G00 adds a 2-gate delay on WR#. Full schematic in post #18507781.

Is a plug-and-play board available?

Yes. Pre-assembled replacement modules appear on eBay for ~90 EUR [Elektroda, amigos, post #18421610] They clip into the 20-pin header—no soldering—yet still use SSD1305 inside.

Statistic: how much money do DIYers actually save?

Forum users report 170 PLN parts + 100 PLN labor versus 900 – 1 000 PLN service, a median saving of 74 % [Elektroda, jacenty67, #17179483; nioop, #17062856].

Can I reuse the old boost inductor and diode?

Yes—if L1 (10 µH, 4532) and D1 (MBR0530) test OK, resolder them onto the new PCB to match NIVONA’s 12 V design [Elektroda, amigos, post #18233157]

3-step How-To: swapping the OLED panel

  1. Unsnap front fascia, desolder 31-pin ribbon, lift old SSD1303 OLED.
  2. Solder new SSD1305 or attach SPD0301 to adapter; fit boost PCB onto 20-pin header.
  3. Bridge D0 (pin 7) per schematic, reassemble, set clock.

What if the new OLED flickers or is dim?

Reflow TPS61045 and check R4 (set to 120 kΩ). An undervalued R4 limits Duty, capping boost at 8 V and causing flicker [Elektroda, jackmc, post #18490466]

Can I order parts locally instead of AliExpress?

Yes. SSD1305Z modules are stocked by BuyDisplay (~24 USD) and Polish sellers (white/yellow, 130 – 160 PLN) [BuyDisplay, 2020; Elektorda, mipix, #18358600]. PCB components are common 0402/0603 passives.

Expert tip for beginners?

“Flux, flux, flux—then the 31-pin ribbon solders itself,” advises user amigos [Elektroda, 18573539] Clean with IPA before final assembly.
