Felix 2 LCD Backlight?

[Kentxu]

If i check the display connector on the Felix 2.0 pcb i get on all datalines (D0-D7) signals

Strange that you get all 8 data lines. It seems that in the PINS.h file only 4 are defined. Any I only saw 4 lines with data on my printer.
Perhaps you have different firmware...

And you are right about quality control, this display should never be sent to u.

Also the main board had a dry joint.

Well Done, Glad you sorted it all out
