I have KIA SUPER KIA TURN 15 CNC lathe with FANUC 21T controller. It was out of order for months. After switching it on again, the monitor of it was displaying unidentifiable characters (I attached a photo). The battery changed on controlle
The machine everything is fine ---the axes are fine, main spindle, revolver head move---,
but the monitor does not work properly.
Have you got any idea about the problem?
Can you help me?
Thank you for your help in advance.
