I don't have an oscilloscope. :-(

OK, thank you very much for your help and patience!

If I could find the answer to this problem, I'll post it here.

Thanks!

OK sorry but I am at a loss to suggest anything else.
Anyone think of something not tried yet?

i understand:
> you have tried different chips in diferent roles... first or second in the chain
> and the chips in paralell to confirm basic functoionality

The only breakage appears to be in the SOUT -> SIN ?

Have you tried using different different locations on the bread board? it could be damaged on the sout pin of the first chip..

It's seems so. The first 3 ports of the second TLC do the same as the first 3 ports from the first TLC. All other ports from TLC 2 are open (LED on).

An rebuild on another bread board makes no difference.

I've found the solution to the problem.

It was my fault. I had adjusted the wrong tlc_config.h file.
I had adjusted the tlc_config.h out oft the BasicUse example folder.
The correct file would be finde in the arduino-0018\libraries\Tlc5940\ folder.

Absolute Beginner Mistakes!  >:(

OK, I say again thank you to all who helped me!
