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]

    amigos: great work!
    One more request: since I've only worked with Eagle so far, can you also provide the board layout as an Eagle file? Thank you very much.

    Hi @All,

    what voltage did you order the components for?

    For e.g. 100 nF C-0402 >>> 10V / 16V / 25V / 50V???

    Or can someone send me the mouser / farnell shopping cart?

    Thx @all

    The highest voltage is around 12-13V behind the inverter. Buy 16V or higher and it will be ok.

    Hello,
    I ordered pcb from post 172. Soldered components and display ssd1305 (short cable) but image is still reverted. Tried same display to original plate, same reverted picture. Now the display seller told that maybe I received ssd1309 display. Does the ssd1309 have different pinout?

    Pinout ssd1305 i ssd1309 jest taki sam. Na pewno dostałeś ssd1305 bo przy ssd1309 jest brak linii taki sam jak w poście #189. Sprawdź dokładnie lutowanie układów IC. Daj zdjęcie zlutowanej płytki od strony układów.

    Is the capacitor C5 short to diode D1? SMD would be better.

    I don't think so, but maybe it'll work and it will talk. The diode and capacitor are in the inverter block and it would probably affect the display lighting itself. From what I write, it shines ok only does not reverse so I would look more for short circuits in ICs, especially 4071 and IC3 because there are 2 vias there. Maybe a tin came over.

    Diode is not shorting. Replaced three times all IC-s. Mesured that nothing beneth ICs not shorting. No result, still reverted. One possibility, that I ordered wrong pcb from post 172 (untitled_ok_5_new_SSDzFCP_Gerber.zip). Also soldered second pcb with all components, still reverted.

    Hello everyone
    I have a problem with the SPD0301 display and pcb by satanistika on 24pin. My display has uneven backlighting in the lines and wraps the image display by 3 lines (first photo). What could be the reason? Maybe someone had a similar effect.
    Regards

    No line or curl, as you describe, is a normal symptom on SPD0301. The fact that you have uneven backlight is assuming a problem in the TPS converter system and therefore a lower backlight voltage. It looks quite dark. Check if you have surely given the right resistors or a well soldered coil and if you have a short circuit somewhere.

    As suggested by Amigos, I smeared with flux and soldered TPS. The effect - as can be seen.
    Thank you very much for help.

    And a revelation. Next equipment saved and user happy :) Thank you for your points, although you have very few of them. That is why I give a good start to collecting because without activity it is hard to collect something ;)
    Regards!

    I had the same display as you. This is the same as in post # 160 and worked ok https://www.elektroda.pl/rtvforum/topic3435827-150.html#18000551. The problem is rather something else :(
    And out of curiosity, send a picture of a clean plate from both sides. Have you replaced IC3? There are grommets close and easy to short-circuit.

    The next dead man was made (photo 1). Thanks a lot amigos. After some time, a slightly brighter vertical line appeared (photo 2) but after a while it disappears (photo 3) but this is probably a defect of the display itself.

    And great. Remember that without Satanisticka it wouldn't be. I think that this error may be the result of some inaccuracy on February. I see that you have already folded yours, but if this happens again, undress and correct all soldering points, especially on the display tape. Espresso machines are great in my opinion and I wouldn't exchange my own for another. That is why it is worth saving them :)

    In my opinion, a 99% display defect, so-called vertical line, probably not glued to the COG (chip on glass) driver, as it is called.
    Although so unusually a bit, because from what I see, the line does not run through the entire height of the display. In small displays it is used to place the driver directly on the glass, e.g. in TV sets it is placed in the middle of this connecting tape with the plate.

    My project has resumed the tile, now you do not need to remove the plastic pin under the display. If anyone is interested, I have several more. We solder, cut off one pin and connect it with a wire to a square solder point on the board and that's it. You do not need to change anything except the display.

    Correction is the IC displacement and making an undercut under the dowel so that the plate does not interfere with the mounting of the frame under the display.

    No revelation. Finally something professionally done. Are you ready to share your project or are you just selling ready-made tiles? I don't need it right now, but I'd like to look through the documentation with the project. What did you design it for? I like this performance and it may be useful one day ;)

    The diagram below. I didn't order tiles - I can throw gerberas and if anyone is willing, they can order pcb to test it. The project was made in Altium.

    This is what the tile looks like now, version without sm.

    Two printed circuit boards, one with a mounted integrated circuit, the other circuit is empty.

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.
