When updating an application on a V350 the screen turns black at startup, it actually blinks very fast. I reinstalled the previous application and it works correctly again. Do you know any reason to find the solution? regards

Are you doing anything special with screen jumps, for example using ladder functions to jump between HMI screens?  It sounds like the unit is flipping between HMI screens.

It happened to me when I had "Set String Library"  called in every scan.

Easiest way to find error if you have your program divided into subroutines is to put MBs you don't use in front of "subroutine call" in main routine and call them one by one by setting MBs.
