I bought replacement display from Slovakia.
https://www.soselectronic.com/products/bolymin/bl-12864g-ernhn-1-52156 30.3 Euro
It works fine, but it required 3 displays in total, I accidentally destroyed the 2 first displays when trying to desolder those very fragile zebra strips... practice makes perfect!
But now the multimeter is like new with the OLED display from SOS Electronics!

I can confirm that this display is identical to the original and works, at least on a U1273AX. It's a shame this store has a 50 euro minimum order, but I also needed other stuff, so it worked out fine.
The replacement is easy to dessolder from the original board with hot air, but at the slightest mechanical pressure the ribbon will tear from the solder pads, it is really sensitive.

I didn't see anything about it so I've made a video of the procedure on youtube.

Here's the video. Nice recovery on the torn ribbon cable, José.

Cool video buddy!

I have the U1273 which has the "OLED screen" too. Cool to know there is a fix if the screen poops out on me! They seem to be hit and miss? Some people say "they are terrible only using it very lightly" and others say "oh, mine has been going fine for years used loads every day" so who knows?

Yeah, makes you wonder if there were just bad batches of them from the screen manufacturer.

Yes, that may have been the case, or perhaps other environmental conditions such as storage temperature and humidity. Also, there seems to be more concentrated on the prior generation U1253.

José, nice video BTW!

Finally my new screen arrived and I installed it successfully.

I bought it for 18~20 USD, from taobao.

Nice job buddy, well done! Hopefully it lasts you for years now.

Hi, I'm from Germany. Through research, I met this forum and I am pleased about the quality of the posts. In Europe, there is a similar problem with the 164x64 Oled with SDD1303, which is installed in the high-quality coffee machines of the Nivona 8-series.

o far, it has been in the forums Germany, Holland, Poland only managed to replace the yellow display BL12864G, the display is now voided in the European market. There are individual pieces in Russia, but they do not deliver abroad.
The yellow display is a compromise because white displays are not available at all.
White displays with the SDD1309, 1305, 1325 drivers are easier to buy, but how are they connected electrically?
Promising attempts have been made in this forum but the final procedure is still missing.
Unfortunately, I understand too little of the matter, but I could try out finished solutions with my coffee machine. So I would be very grateful if you could help me to replace the Oled Display 1303 by an Oled with the driver SDD1309 or similar.
Thank you

what do you mean by "the display is now voided in the European market." ??

There are SDD1309, 1305 displays with the same pinout as SSD1303, no electrical differences. However these controllers are not identical in commands they support. Using them in keysight meters results in mirrored image. You may try them, though. If you are lucky and unsupported commands are not used in particular device, it may work just fine.

Sorry my english is bad.
There are no Oleds to buy in Europe with SSD1303
Thanks stj for the info.
But my SOLOMON technical data sheet has a pinout of PIN 25-29 on the SDD 1303. SSD 1309 has NC there.

Hi Latet,
the Oled has the driver SSD 1305z, because the columns are reversed?

Rosenköpfchen · « **Reply #138 on:** February 10, 2019, 04:08:47 pm »

Hi,
a question to the experts. Could this OLED be installed for replacement?
Thank you

Dont think so, may have the good chipset, but see the connector ........ it wont do unless you make somekind of daughter board

Latet · « **Reply #140 on:** February 12, 2019, 05:30:55 am »

Hi Rosenköpfchen, the seller has changed the product, $:-\$ be careful. Search it as SSD1303T10 driver, and check the size you need.

Rosenköpfchen · « **Reply #141 on:** February 12, 2019, 09:04:43 am »

Many Thanks

Has anyone considered soldering in a connector for the LCD? If the display has a shelf life of ~4months - 3yrs depending, why not solder in a ribbon connector / Rotary Backlock Type connector to the agilent daughterboard?
I'm down for researching a connector, I just need the pin pitch.
Also, the Adafruit Monochrome 2.42in 128x64 dot monochrome oled display looks to be a similar pin pitch, but it does not look like there is a chip-on-flex like the other oled displays.

Hi All,

Desperately trying to find a replacement screen with SSD1303 it seems there are none in stock anywhere, anyone know of anyone who has stock?
Cheers

Hi,
Now again new display was produced with the driver SSD1303

.
Look here for ..https://www.coffeemakers.de/Nivona-Displayeinheit-691-NICR8xx-64758-3268?gclid=EAIaIQobChMIubn08umJ4QIVV-J3Ch3ytwl8EAQYASABEgKaN_D_BwE

jdurango · « **Reply #145 on:** March 26, 2019, 01:06:39 am »

Just to clarify, is the SSD1303T10 the correct screen for a u1253b? Seems like most everyone in this thread is dealing with A or AX models. Thanks!

ntrx · « **Reply #146 on:** March 28, 2019, 01:41:20 am »

I'm wondering this too, I can't find a compatible 1303 driver oled anywhere but can get a replacement screen for the B.
I have an A and don't want to spend the $220AUD if it isn't the same.
In actual fact I can't find an OLED display of the correct dimensions at the moment at all, if I can get one with a 1305 or one of the other drivers that just requires a flip command on power up I will start work on a replacement screen board with a PIC to hijack the comms on power-up.

Rosenköpfchen · « **Reply #147 on:** March 28, 2019, 01:07:55 pm »

Hello, with the SSD 1305, the image is mirrored. There is column offset with the SSD1309.
Problem is to reverse the mirrored.

ntrx · « **Reply #148 on:** March 29, 2019, 03:13:19 am »

Was your old OLED driver 1303 or 1305? I am currently trying to find 1305 so keen to know where you got this one please?

Rosenköpfchen · « **Reply #149 on:** March 29, 2019, 03:02:33 pm »

Hello,
original was the driver SSD 1303 installed. Then the driver SSD 1305 was installed and the image is mirrored.
Oleds with SSD 1305 can often be found at Chinese retailers,
eg: https://www.ebay.com/itm/Green-2-4-inch-128x64-OLED-Display-Module-I2C-Serial-SPI-SSD1305-w-Tutorial-/291844721833?hash=item43f34d0ca9&tfrom=301226745140&tpos=unknow&ttype=price&talgo=origal
