1. Check online SI 9 - LCD Backlight intensity

Set it to 100 if it is low.

*It may be 0.

2. Touch display for more than 5 sec and check if you can see INFO mode display.

3. Connect to COM 1 of PLC and repeat all system files update.

If you go back to the original O/S what happens?  Is there an actual need to change it?  If it works and does all that is needed, don't change it. 

And something left field, did you install Visilogic as Run as Admin, and have you got the program's .exe set to Run as Admin as well?  I can't see that this would create the problem, but worth asking as sometimes the "correct" installation resolves strange comms issues.

cheers, Aus
