Hi!
I've designed a board with 6 daisy-chained TLC5940 and 5 of them are working perfectly, but the second chip in the chain does not. When i connect the power supply the leds connected to the second one lights up (not happening for any of the leds connected to the other chips) and when i start sending data to control them the second chip's leds are turned off.
I find this somewhat strange since all the TLC5940's are connected the same way, and there are 4 tlc5940's connected after the faulty one in the daisy chain so the serial so the SOUT is obviously working. Also the strange error mode of having them turn on when powered but then turn off when i ask them to actually do something confuses me.
Any ideas? :) Is there any known mistake that might cause this kind of error mode?
