The LCD on my Taz 4 powers on but is blank.
I reseated the two cables behind the lcd, as well as the serial cable that connects to the outside of the control case. I also reseated the two sets of female headers that connect to the Rambo board.
I did a continuity check with a multi meter from the female headers inside the case to the serial connector that’s outside the case (tested fine).
I’m able to print via USB fine.
Is there anything else I can?
EDIT: Forgot to update this thread. I replaced the LCD and it’s working fine. Looks like the LCD just failed.
