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

I poured the flux in February and gently corrected it with a new tin. Then the hot air at 200 degrees and the ribbon gently heated itself goes away. Nothing is lost.

If you've done what your friends write, you probably have a damaged motherboard. I had the same symptom, capacitors and diode are damaged on this board. After the exchange everything will work, the diode is small SMD, the capacitor I do not remember, tel. 886081288.

And whether you can find out which capacitors and which diode, because I have such a problem that the Nivona 830 does not turn on. I could send a photo of the tile as needed.

After replacing the plate, my coffee maker has a damaged display, but the mechanism moves, and the voltage measurements are attached.

Does anyone have a display on the sale, or know where to currently take such? I searched all pages and missing. There are other models in Slovakia and you are kindly informed that BL12864G2ERNHn already have a different controller and no longer matches Niwona.

I took a chance and bought such a display at TME: REX012864HWPP3N00000. Everything would be fine (it shines in white) if it were not that it is the other way round - i.e. from the back. But in the mirror - perfectly Costs: 100 PLN display with shipment + 100 batching. But recently I found something like this: on lcds-screen.com (China) - RGS24128064WW001 - I am waiting for a quote, or on engtaobao.com you can look for SSD1303 - only that it shines yellow, but the price with a transport of around 30-40 PLN.

Has anyone found a supplier of white, blue or yellow OLED?

Hello. Fits the following "Display Elektronik DEP128064G-Y", which can be purchased at sklep.eltron.pl. Yellow. The cost is about 260 PLN with shipping. They still have 3 pieces, Mutated thanks to their friend's courtesy (thanks !!!) and it works greetings

Thank you, I'm happy biniu01.

With this REX012864HWPP3N00000 is an interesting thing. It would be a nice alternative, but if you can do something about it, then someone who plays with LCD displays professionally would have to say The outputs look sorted identically, and are only numbered from the other side. The size is also the same. Somewhere, I read that the ssd1306 and ssd1309 drivers are compatible with ssd1303, but maybe this is not entirely true. I am tempted to test, but I do not have any damaged: / Maybe someone has a beaten display for sale, of course for some money I see that with a mirror reflection it is still a problem. I do not think there is a chance to adapt ssd1309.

SSD1309 and 1305 OLED reflects the display and shows the speakers upside down. The solution would be an FPGA adapter for SSD1309 / 1305. It would be safer in the future. I just do not know about it. It would be great if someone started the project and solved the problem. A faulty display is currently available on eBay, about 16 EUR.

I was convinced that it displays rather like in this post, and thus from the back. https://www.eevblog.com/forum/repair/u1253b-oled-replacement-problem-screen-inverted/ Guys can not deal with it either. https://www.eevblog.com/forum/testgear/replac...ed-screen-on-an-agilent-u1253a-multimeter/50/ As a last resort, if the menu worked properly despite the mirror reflection, then as for your own needs would also be some solution Thanks for the info about ebay. I see that it is for 11 euros + shipping, so probably it's about. I am trying to buy the entire coffee machine at a good price, but if I can not, I can buy the display myself. This is an auction, but nobody can fight. Thanks.

Dear colleagues, please tell me where else you can buy a display for Nivony 830. Maybe someone has recently bought. I would ask for some other information than those given in the subject.

I would also be keen on the display, or would send someone to repair.

I found a repair announcement of this display on Olx and I used it. The offer concerned the exchange for 380 PLN plus shipping. The display works, it's yellow, so it was a store of previous matching ones. I can see that the user's ad is not up to date, so probably the displays are over.

I think that we have to say goodbye to Oled SSD 1303. The driver is no longer produced, and the OLEDs with this driver are old. They have already lost their endurance. My friend changed the display in Nivon for a lot of euros and after 1 year he was again unfit. The future belongs to OLED with SSD1305 or 1309 with an adapter. Only who can make this adapter?

From what I read in the English topic, the guy to the meter has installed the second generation BL-12864G2 ERNHn display and displays correctly (from what I have read, the meter is on the controller 1303, i.e. such as Nivona). But in turn here Marek09 called Slovakia and the guest claimed that the BL-12864G2 ERNHn display has a different controller and does not match Nivon. Now who to believe ?? I mean this topic ---> https://www.eevblog.com/forum/repair/u1253b-oled-replacement-problem-screen-inverted/

I gave the faith of the seller. Anyway, call me and ask. https://www.soselectronic.pl/kontakty The company has a branch in Poland, so they speak Polish. I gave only the display model, and the nice gentleman immediately asked: "Probably Nivona?" I replied: "Yes." Lord: "Unfortunately, it will not match." These are from the new delivery and have another controller. " So I did not risk it and I gave up the purchase. Anyway, see. https://www.soselectronic.com/products/bolymin/bl-12864g2-ernhn-1-300047 The controller is: SPD0301, so another ... Maybe a colleague will risk buying and confirming? It's just that such a display on SPD0301 can already be bought almost anywhere, and already for about PLN 40. You can try to join him on the spider and see if he moves.

You misread the translation because he wrote it a bit intricately. This is the Pole "Paw". He only states that there are new modules in SOS. He has also got a display on ssd1303 somewhere and he is mistaking you for the picture. There is nothing that the new module fits. I wrote with him. The specification and appearance of this new speaks for itself. Does not fit.

Ok, thanks for the info. So you have to look further, or rather combine over the adapter ...

I think that here you need some wise man who knows it The original module with display inserted into Nivony is marked P19702. All these modules were once available in China and then you do not need to sold the display itself, but only the entire board on the 20-pin connector. Below I attach the found specifications of the original module. Maybe someone will be useful. It is also interesting whether the BL12864G module is interchangeable with the BL12864G2 module without changing the target device of the appropriate software to operate another display on a different controller. If it's interchangeable, and I do not see a separate processor for the display on the module, it seems to me that the software in Nivon should handle it. But it's just logic, not relying on the facts of electronics As for the display on spd0301, although it is 24 pin rather than 31 as ssd1303, it has identical pin symbols with the exception of the additional BS0. The order is different, but it can be done with an adapter. Because I do not know how much it is necessary to connect BS0, my intentions end there On the top left SPD0301, on the right SSD1303 Below the info on the entire Nivony P19702 module

Hello, now new displays with SSD 1303 driver have been produced. Take a look at https://www.coffeemakers.de/Nivona-Displayein...MIubn08umJ4QIVV-J3Ch3ytwl8EAQYASABEgKaN_D_BwE

Why do you think that they will be with the ssd1303 driver? I bet they will be with the spd0301 display. Instead of soldering points for soldering, ssd1303 will be a FPC 24 pin socket under spd0301 I do not know when I will have everything to assemble and test this new display. The biggest problem is that I do not have a damaged module from the Nivony display. I bought it on eBay, but before it reaches my friends it will probably pass a month. I will certainly check my own thesis and if it works, I will share with you. I think it will be a solution that will need to be refined in terms of assembly in the old module A practically needed development of a small board making an adapter with FPC 24 with the possibility of soldering to 31-pin soldering points on the old display. I will tell you that according to the Chinese, spd0301 is a substitute for ssd1303 which unfortunately differs in a kind of connector: / I am looking forward to checking it out

I join the subject. I have two to repair. Does anyone have any new information?

Today I launched a mirror image on the SSD1309 model REX012864HWPP3N00000. In addition to mirroring, there is also the problem that the original display had a resolution of 132x64.

As far as I know, the original has 128x64. Why do you think that 132x64? Can you normally select menu items despite mirroring?

Yes. There is no problem with service.
I have Nivona 850 and she has 132x64 on ssd1303. Four missing columns are visible from the right.

I'm happy with the PLN 90 spent instead of PLN 900

I will not argue, but all the original displays packed in these modules in 830, 840 and 850 were the same. They were ssd1303t10. The issue of a lack of lines is probably a problem in something else. I have Nivona 850, where I replaced the display with yellow and I assure you that it is 128x64 Ssd1303t10 were probably only 128x64 because it is a model of a specific display of a particular size. If you're old, read the symbol on it. I posted a specification here somewhere. If the menu works, there is always a solution The most important thing is that you can brew a cup of coffee Maybe someone has a damaged display / module / for sale at a reasonable price? I need to test. I bought, but they will be in me for about 3 weeks, and I am impatient

I did not penetrate that much, but in the specification for SSD1303 they write 132x64. Maybe I did something wrong or the display requires some initialization ... The most important thing is that the coffee does Does anyone know where to find info on the poor frothing of milk (low steam pressure) - I think it's not this thread, sorki. Added after 2 [hours] 3 [minutes]: Problem foaming solved - check valve.

Hi Amigos,

I am also curious if your experiment has been successful. That would be a great break !!

Palal, which check valve?
