It is the resistor on pin 20 of the chip.
What value do you have?
Double it.

ok... put two 2k in series then  = 4k. Still no change though. Other suggestions?

In case I can´t fix this issue with the TLC5940's, is there another way to get 30 LEDs to breathe smoothly in different duration/speed?

Nearest that i can tell, about a million ways. seriously there are a lot of ways to control leds.

So time for some fault finding.
Use the code that just lights up one device, I think you said that still worked, chech it still does.
Then switch over the input to the other chip by changing the input wire only. If that now works it is your software that is wrong. If not then it is wired wrong.
