OLED display faulty.

[Gods]

Hello, the OLED display on my RS232 WIModem is faulty. It works intermittently, mostly off. 
It's definitely the display because I connected a different white one and it worked fine. But this one has the "VCC and GND" pins reversed, so it's not compatible. 
And what is its actual size?
I ordered a 1.3-inch display (from AliExpress), but it's too big.
What is its actual reference number? (It's difficult to find the layout of the "Vcc-Gnd-Scl-Sda" pins).
I can't send it to you because I'm in Europe. Thank you.

You likely pressed on the one of the lower corners and snapped the glass. That breaks the display, typically where every other line is missing.

That is a custom display, but you can find them through Aliexpress, as that is where I get them.

Hi,
This is unlikely, the PCB is in a 3D printed case. It also causes problems in the I2C bus because sometimes the LED is off too. 
Can you please give me an AliExpress link for the screen?  Thanks.

This one is Good ? https://fr.aliexpress.com/item/1005004355547926.html

The LED is not I2C. If you did not trim the 4 solder joints that are on TOP of the display, you can break the circuit board (barrels for the signal pass-through) when using a 3D printed case. You have to trim those to be below the height of the glass! People who make these cases don't tell you that. I have had quite a few people end up with broken boards and displays due to the various cases made.

That is the correct display! MAKE SURE you trim the 4 solder joints on that display before you install it!
