ESP8266 p10 Panel start problems

Hi
I am using p10 dip panels and using dmd2 library. I do not have a problem with these panels, but when I use the smd p10 panel, the panels do not work, sometimes they work without problems, but mostly they do not. What would be the reason?
note: there are 16 ic in the dip panels, 8 ic in the smd panels

Are these panels monochrome, two color or RGB?

Monochrome ,Only white

The reason can be a logical level of esp8266 signal - 3.3v
Try to use logic level converter 3.3 - 5v on all signal lines
