This is how you post a link on this forum.
And this is how you post a picture:
I have used many clone max7219 chips that look like yours and I have never had a problem with them, and I have spoken to many others who say the same. But I have also heard that they can be faulty, so it's not impossible you have a faulty chip, but unlikely.
Post a schematic showing how you connected it up (not someone else's schematic, draw your own, pencil & paper is ok). Also post close-up, well-focussed, well-lit pictures of your circuit so every wire can be followed.
Also please confirm you have followed my test instructions from post #3 with the display you are using, to prove they truly are CC and the are no faulty segments.
